High-Throughput Screening of Bicationic Redox Materials for Chemical Looping Ammonia Synthesis
Publisher: Wiley
Date: 24-07-2022
Abstract: Ammonia recently has gained increasing attention as a carrier for the efficient and safe usage of hydrogen to further advance the hydrogen economy. However, there is a pressing need to develop new ammonia synthesis techniques to overcome the problem of intense energy consumption associated with the widely used Haber–Bosch process. Chemical looping ammonia synthesis (CLAS) is a promising approach to tackle this problem, but the ideal redox materials to drive these chemical looping processes are yet to be discovered. Here, by mining the well‐established MP database, the reaction free energies for CLAS involving 1699 bicationic inorganic redox pairs are screened to comprehensively investigate their potentials as efficient redox materials in four different CLAS schemes. A state‐of‐the‐art machine learning strategy is further deployed to significantly widen the chemical space for discovering the promising redox materials from more than half a million candidates. Most importantly, using the three‐step H 2 O‐CL as an ex le, a new metric is introduced to determine bicationic redox pairs that are “cooperatively enhanced” compared to their corresponding monocationic counterparts. It is found that bicationic compounds containing a combination of alkali/alkaline‐earth metals and transition metal (TM) ost‐TM/metalloid elements are compounds that are particularly promising in this respect.

Magnetotransport dependence on the field magnitude and direction in large area epitaxial graphene film on stretchable substrates
Publisher: AIP Publishing

DOI: 10.1063/1.4794868
Abstract: We report the magnetotransport properties of large area graphene on stretchable polyethylene terephthalate substrates. At 2 K, weak localization of electrons introduced negative magnetoresistance at low field a transition to positive magnetoresistance followed as the external field increases. Our results suggest that weak localization contributes to Hall effect at low temperature. At room temperature, only classical Lorentz force contribution can be observed. Angular dependence of the external magnetic field on longitudinal and transverse resistivity is measured to test the interplay between weak localization and Lorentz force contribution. Quantitative simulations based on quantum interference theory produced excellent agreement with the experiments.

Screening rare-earth aluminates as promising thermal barrier coatings by high-throughput first-principles calculations
Publisher: Wiley
Date: 16-01-2023
DOI: 10.1111/JACE.18970
Abstract: Thermal barrier coatings (TBCs) play an important role in gas turbines to protect the turbine blades from the high‐temperature airflow damage. In this work, we use first‐principles calculations to investigate a specific class of rare‐earth ( RE ) aluminates, including cubic‐ RE AlO 3 (c‐ RE AlO 3 ), orthorhombic‐ RE AlO 3 (o‐ RE AlO 3 ), RE 3 Al 5 O 12 , and RE 4 Al 2 O 9 , to predict their structural stability, bonding characteristics, and mechanical and thermal properties. The polyhedron structures formed by the Al–O bonds are stronger and exhibit rigid characteristics, whereas the polyhedra formed by the RE –O bonds are relatively weak and soft. The alternating stacking of AlO 4 tetrahedra, AlO 6 octahedra, and RE –O polyhedra, as well as the selection of RE elements, shows intensive influences on the expected mechanical and thermal properties. The B , G , and E of these four types of aluminates decrease in the order of c‐ RE AlO 3 o‐ RE AlO 3 RE 3 Al 5 O 12 RE 4 Al 2 O 9 . RE AlO 3 and RE 4 Al 2 O 9 are brittle and quasi‐ductile ceramics, respectively, whereas RE 3 Al 5 O 12 is tailorable. The minimum thermal conductivity is in the range of 1.4–1.5 W m −1 K −1 for c‐ RE AlO 3 , 1.3–1.4 W m −1 K −1 for o‐ RE AlO 3 , 1.25–1.35 W m −1 K −1 for RE 3 Al 5 O 12 , and 0.8–0.9 W m −1 K −1 for RE 4 Al 2 O 9 . RE 4 Al 2 O 9 with low thermal conductivity and damage tolerance is predicted to be the potential candidates for next‐generation TBC materials.

Magnetic scattering effects in two-band superconductor: The ferromagnetic dopants in MgB2
Publisher: IOP Publishing
Date: 12-03-2010
DOI: 10.1088/0953-8984/22/13/135701
Abstract: This paper demonstrates the magnetic scattering effects on the electron-phonon interaction in two-band superconductors based on the transition-metal-doped MgB₂ to clarify the effects of magnetic dopants on multi-band superconductivity. The phonon properties of polycrystalline Mg(1-x)M(x)B₂ (M = Fe, Ni and Co), with x up to 0.05, were studied, with the investigation based on the normal state Raman spectra, especially the variation of the E(2g) mode. The magnetic scattering effect of Fe is much weaker than that of Mn in MgB₂, while it is stronger than that of Ni. The weak magnetic scattering effects are responsible for the superconducting behaviors of Mg(1 - x)Fe(x)B₂ and Mg(1 - x)Ni(x)B₂. Co shows almost no magnetic scattering effects on the superconductivity, while the depression of the critical temperature, T(c), in Mg(1 - x)Co(x)B₂ is attributed to the phonon behavior and is independent of the ferromagnetic nature of cobalt.

Serum soluble nucleosome and the broad family of antinucleosome antibodies are associated with organ and tissue damage in systemic lupus erythematosus in a Chinese population
Publisher: Oxford University Press (OUP)
Date: 03-2008
DOI: 10.1111/J.1365-2230.2007.02669.X
Abstract: Nucleosomes and the broad family of antinucleosome antibodies (ANAs anti-double-stranded DNA, antihistone and antinucleosome antibodies) may contribute to the pathogenesis of systemic lupus erythematosus (SLE). We collected clinical information on 90 patients with SLE and 73 healthy volunteers and measured serum levels of the ANA family using a double-sandwich ELISA. The results showed that the levels of serum nucleosomes of patients with SLE was significantly lower and the levels of ANA were significantly higher than healthy controls. Negative correlations between serum nucleosomes and ANA, and positive correlations between in idual ANAs were found. Patients with SLE with positive ANA had a significantly higher frequency of renal disorders than those with negative ANA. Determination of serum nucleosomes and ANAs contributes to SLE monitoring.
Photocatalytic Properties of TiO2: Evidence of the Key Role of Surface Active Sites in Water Oxidation
Publisher: American Chemical Society (ACS)
Date: 28-08-2015
Abstract: Photocatalytic activity of oxide semiconductors is commonly considered in terms of the effect of the band gap on the light-induced performance. The present work considers a combined effect of several key performance-related properties (KPPs) on photocatalytic activity of TiO2 (rutile), including the chemical potential of electrons (Fermi level), the concentration of surface active sites, and charge transport, in addition to the band gap. The KPPs have been modified using defect engineering. This approach led to imposition of different defect disorders and the associated KPPs, which are defect-related. This work shows, for the first time, a competitive influence of different KPPs on photocatalytic activity that was tested using oxidation of methylene blue (MB). It is shown that the increase of oxygen activity in the TiO2 lattice from 10(-12) Pa to 10(5) Pa results in (i) increase in the band gap from 2.42 to 2.91 eV (direct transitions) or 2.88 to 3 eV (indirect transitions), (ii) increase in the population of surface active sites, (iii) decrease of the Fermi level, and (iv) decrease of the charge transport. It is shown that the observed changes in the photocatalytic activity are determined by two dominant KPPs: the concentration of active surface sites and the Fermi level, while the band gap and charge transport have a minor effect on the photocatalytic performance. The effect of the defect-related properties on photoreactivity of TiO2 with water is considered in terms of a theoretical model offering molecular-level insight into the process.

Electrochemical performance enhancement of LiNi0.6Co0.2Mn0.2O2 at high cut-off voltage by aluminum-doped polypyrrole coating
Publisher: Research Square Platform LLC
Date: 20-03-2023
DOI: 10.21203/RS.3.RS-2687335/V1
Abstract: LiNi0.6Co0.2Mn0.2O2 (NCM622) is a kind of high nickel ternary cathode materials for lithium-ion batteries with high energy density and high discharge platform. However, the insufficient electron/ion conductivities and corrosion of hydrofluoric acid has limited its practical usage. In overcoming the challenges, it is particularly important to find a method that can improve both electronic and ionic conductivities of such a material. In this study, aluminum (Al)-doped polypyrrole (Al@PPy) is used to coat NCM to improve its rate and cycling performance. Compared with the uncoated NCM, Al@PPy-NCM has more electron/ion transport channels and much better cycling stability. It has an initial capacity of 224.3 mAh/g at a current density of 20 mA/g, and a capacity retention rate is 91.6 % after 100 cycles in voltage range of 3.0~4.5 V. At a current density of 200 mA/g, the initial capacity can still be 185.1 mAh/g, and the capacity retention rate can maintain 88.1 % after 200 cycles.

Unveiling surface stability and oxygen vacancy segregation of Yb2SiO5 and Lu2SiO5 by first-principles calculations
Publisher: Wiley
Date: 12-04-2023
DOI: 10.1111/JACE.19132
Abstract: RE 2 SiO 5 ( RE = Yb and Lu) are significant environmental barrier coating (EBC) materials, in which surface and oxygen vacancy play crucial roles in their structural stability and functionality. In this work, the structural configuration and thermodynamics of (1 0 0), (0 1 0), and (0 0 1) surfaces of RE 2 SiO 5 are investigated by first‐principles calculations. The (0 0 1) surface is preferred energetically, which is attributed to the weak bond broken environment and large rare‐earth polyhedron distortion on this surface. Moreover, the formation energies of various oxygen vacancies on the stable (0 0 1) surface are estimated and the optimal location for oxygen vacancies is held by the [SiO 4 ] tetrahedron. The oxygen vacancies are more likely to segregate on the surface because of the lower formation energies on the surfaces compared with those in the bulk. These findings are expected to enable the development of RE 2 SiO 5 ‐based EBCs by tuning grain size and/or thin film growth orientation.

The effects of size and orientation on magnetic properties and exchange bias in Co3O4 mesoporous nanowires
Publisher: AIP Publishing
Date: 28-03-2011
DOI: 10.1063/1.3548831
Abstract: Co3O4 mesoporous nanowires with average single crystalline grain sizes of about 8 nm, 12nm, 25 nm, and 45 nm were synthesized by sintering of microwave-assisted hydrothermal processed belt-Co(OH)2 precursors at 300–500 °C for 2 h. Microstructure analysis was conducted by x-ray diffraction, x-ray photoelectron spectroscopy, Raman spectroscopy, scanning electron microscopy (SEM), field emission SEM (FESEM), transmission electron microscopy (TEM), and high resolution TEM (HRTEM) to confirm the composition, structure, and orientation in the nanowires. Systematic magnetic measurements have also been conducted on the nanowires. It was found that the size and orientation have significant effects on the magnetic and exchange bias properties. The interesting finding was made that room temperature ferromagnetism appeared at 350 °C in the high orientation s les. Systematic comparison and analysis of the relationships among the grain size, microstructure, orientation (texture), surface electric structure (O vacancies), and defects with magnetic properties (ferromagnetism, coercive field, exchange bias, etc.) are presented in this work.

DOI: 10.1007/S11845-010-0543-X
Abstract: It is necessary to assay multiple autoantibodies simultaneously in the same group of new-onset systemic lupus erythematosus (SLE) patient. To determine the prevalence and clinical significance of 15 autoantibodies in patients with new-onset SLE. Twenty new-onset patients with SLE and 32 healthy in iduals were enrolled in the present study. Serum levels of 15 autoantibodies were detected by enzyme linked immunosorbent assay. The clinical parameters of the patients were also recorded. The positive rate of anti-ssDNA was the highest (85%). The positive rates of anti-dsDNA, anti-ssDNA, AHA, anti-SSA, anti-SSB, anti-Sm, anti-U1RNP, AnuA, and rRNP were significantly higher in SLE patients than in nomal controls. In terms of clinical manifestation, there were significant associations of rRNP with photaesthesia and of AHA with nephritis. Clusters of autoantibodies were identified and associations of antibodies with symptoms were found in new-onset patients with SLE.

Publisher: Wiley
Date: 20-11-2023
Abstract: With the development of flexible electronics, the demand for flexibility is gradually put forward for its energy supply device, i.e., battery, to fit complex curved surfaces with good fatigue resistance and safety. As an important component of flexible batteries, flexible electrodes play a key role in the energy density, power density, and mechanical flexibility of batteries. Their large‐scale commercial applications depend on the fulfillment of the commercial requirements and the fabrication methods of electrode materials. In this paper, the deformable electrode materials and structural design for flexible batteries are summarized, with the purpose of flexibility. The advantages and disadvantages of the application of various flexible materials (carbon nanotubes, graphene, MXene, carbon fiber/carbon fiber cloth, and conducting polymers) and flexible structures (buckling structure, helical structure, and kirigami structure) in flexible battery electrodes are discussed. In addition, the application scenarios of flexible batteries and the main challenges and future development of flexible electrode fabrication are also discussed, providing general guidance for the research of high‐performance flexible electrodes.

Abstract: The influences of lattice strain on the superconducting critical current density Jc and critical transition temperature Tc in pure MgB2 and a SiC-MgB2 composite made by the diffusion process are explored, based on the thermal expansion coefficients and the low temperature effects on Raman scattering. The strong thermal strain provides a strong flux pinning force for the supercurrents at the interfaces between SiC and MgB2. The high Tc of SiC-MgB2 is also discussed according to the expanded lattice and Raman characteristics.

Facile Fabrication of Hybrid Perovskite Single-Crystalline Photocathode for Photoelectrochemical Water Splitting
Publisher: Wiley
Date: 09-04-2021
Abstract: Recently, beyond various optoelectronic devices, lead halide perovskites have emerged as promising candidates for high‐performance photocatalysts owing to their excellent optoelectronic properties. However, most previous works on perovskite photocatalysts mainly used the forms of nanocrystals that need the perovskite‐saturated electrolyte or polycrystalline thin films that still suffer from the instability in water and low performance. Herein, the synthesis of high‐quality hybrid perovskite single crystals and their implementation as photocathodes for water splitting with a simple device structure are reported on. Optimized perovskite crystals exhibit a good water splitting photocurrent density of −0.51 mA cm −2 at 0 V versus reversible hydrogen electrode (RHE) under visible light illumination. Moreover, such devices as the p‐type photocathodes show improved stability, exhibiting no obvious decrease over 600 s. This work highlights the great potential of hybrid perovskite single crystals for photocatalyst applications in aqueous solution.

Abstract: MgB 2 / Fe wires with 10 at. % excess Mg produced by in situ powder-in-tube processing were compared to normal stoichiometric MgB2/Fe wires prepared by the same method. It was found that the critical current density (Jc) and the irreversibility field (Hirr) were significantly enhanced for MgB2/Fe wires with excess Mg. The transport Jc for 10 at. % Mg excess s les sintered at 800 °C, measured at a field of up to 14 T, increased by a factor of 2 compared to that for the normal MgB2 wires. The best Jc results for the 10 at. % Mg excess s le were obtained by heating the s le at 600 °C for 1 h the Jc at a field of 8 T and at temperature of 10 K reached 3×104 A/cm2. The detailed analysis of the effect of excess Mg on the microstructures, the Jc, and the Hirr, of MgB2/Fe wires are presented in this paper.

Platinum dendritic nanoparticles with magnetic behavior

DOI: 10.1063/1.4890506
Abstract: Magnetic nanoparticles have attracted increasing attention for biomedical applications in magnetic resonance imaging, high frequency magnetic field hyperthermia therapies, and magnetic-field-gradient-targeted drug delivery. In this study, three-dimensional (3D) platinum nanostructures with large surface area that features magnetic behavior have been demonstrated. The well-developed 3D nanodendrites consist of plentiful interconnected nano-arms ∼4 nm in size. The magnetic behavior of the 3D dendritic Pt nanoparticles is contributed by the localization of surface electrons due to strongly bonded oxygen/Pluronic F127 and the local magnetic moment induced by oxygen vacancies on the neighboring Pt and O atoms. The magnetization of the nanoparticles exhibits a mixed paramagnetic and ferromagnetic state, originating from the core and surface, respectively. The 3D nanodendrite structure is suitable for surface modification and high amounts of drug loading if the transition temperature was enhanced to room temperature properly.

Abstract: Pulsed magnetic field was first employed in the study on MgB2 superconductors. Superconductivity properties and microstructures of Zn and SiC doped MgB2 were discussed in this paper. The superconductors showed different superconductivities after magnetic sintering. Critical current density and flux pinning force were relevant to the dopants properties in MgB2. Grains in the pulsed magnetic processed MgB2 matrix were smaller than those in the normal processed one. The refinement microstructures have caused the critical current density (Jc) anisotropy in both the Zn and SiC doped MgB2.

Abstract: VNx nanoparticles and nanowires have been prepared by nitrifying V2O5 nanoparticles (NP) and nanowires (NW). The V2O5 NP and NW were synthesized by a facile hydrothermal method. Magnetic susceptibility (χ) and magnetization measurements showed long range superconducting ordering (LRSO) at the temperature of 5.8 K for NW, but there was no observation of LRSO (at least down to 2 K) for the NP s le, which is a much lower temperature than for the corresponding bulk, while both NP and NW showed the absence of long range magnetic ordering, at least down to 2 K. However, the χ data showed that both s les possess a high Pauli-like component, χ0, in their susceptibility (χ0 ≈ 2.22 × 10−4 emu/mol for NP and 5 × 10−4 emu/mol for NW). Moreover, for the NW s les, χ has a strong magnetic field dependence and presents a non-linear field-polarization feature, suggesting strong spin-orbit coupling.

Raman study on the effects of sintering temperature on the Jc (H) performance of Mg B2 superconductor
Publisher: AIP Publishing
Date: 2008
DOI: 10.1063/1.2829808
Abstract: The influence of sintering temperature on the critical transition temperature Tc and critical current density Jc for the MgB2 superconductor was investigated systematically with the observation of Raman scattering measurement and flux pinning force Fp analysis. The enhanced E2g mode in Raman spectra with increasing in situ sintering temperature shows gradual strengthening of the electron-phonon coupling in MgB2, which means that the crystals become more harmonic after higher temperature sintering. However, the crystal harmonicity is degraded for s les sintered at even higher temperature due to Mg deficiency. A possible explanation for the Jc(H) performance, which is in accordance with the Raman spectroscopy observation and Fp analysis, is the cooperation between the electron-phonon coupling in the E2g mode and the flux pinning centers, mainly originating from the lattice distortion due to the different sintering temperatures.

Magnetic Ground State and Tunable Néel Temperature in the Spin ½ Linear Chain Antiferromagnet Co(OH)(2−x) Fx
Publisher: Wiley
Date: 04-02-2022
Abstract: The ground state of Co 2+ in the octahedral CoO 6 crystal field has often been assumed to be in high spin state with S = 3 / 2 . As a result, the effective magnetic moments of Co 2+ are overestimated in Co(OH) (2− x ) F x . Herein, it is argued that the ground state of Co 2+ in Co(OH) (2− x ) F x has effective spin 1 / 2 but not S = 3 / 2 , due to spin–orbit coupling in distorted octahedral crystal field. Analysis of the published magnetic susceptibility (χ) data on three s les of Co(OH) (2− x ) F x is reported here with the new result that the Néel temperature T N decreases with an increase in χ as T N = 36.5, 30.5, and 26.5 K are determined for x = 1.09, 1.14, and 1.26, respectively. The employment of modified Curie–Weiss (CW) law along with S = 1 / 2 ground state eliminates the reported disagreement between the magnetic moment μ(Co 2+ ) obtained from CW law above and neutron powder diffraction (NPD) below The fits of the data to the predictions of the linear chain model yield the exchange constant J / k B = −30.5, −28.1, and −24.7 K for x = 1.09, 1.14, and 1.26, respectively, supporting the chain‐like antiferromagnetic ordering observed using NPD.
Photoelectric cooperative patterning of liquid permeation on the micro/nano hierarchically structured mesh film with low adhesion
Publisher: Royal Society of Chemistry (RSC)
Date: 26-08-2014
DOI: 10.1039/C4NR03496A
Abstract: Stimuli-responsive surface wettability has been intensively studied, especially wettability controlled by photoelectric cooperation, which appears to be a trend for more effective surface wetting. In this field, the patterning of controllable surface wettability is still a challenge in the application of liquid-printing techniques because of the high adhesion and high responsive voltage, as well as low mechanical strength, of the substrate. Herein, we have demonstrated the patterning of liquid permeation controlled by photoelectric cooperative wetting on the micro/nano hierarchically structured ZnO mesh film. The special micro/nano hierarchically structured ZnO mesh is beneficial for lowering adhesion force on the mesh surface than those of the TiO2/AAO nanopore array films previously reported for the discontinuous tri-phase contact line, in addition to precisely controlled microscale liquid movement with considerably lower threshold voltage for the hierarchical structure. Moreover, the stainless-steel mesh with different pore sizes as a substrate behaves with higher mechanical strength and lower cost, compared with the anodized Ti mesh. Thus, this work is promising for accelerating the development of patterned liquid permeation and extending the application of micro/nanofluidic system and micronanoelectronic technology.

The influence of self-field supercurrent on the high-field performance of the nano-SiC-doped MgB2/Fe wires is discussed based on comparison of the critical current densities of the in situ processed nano-SiC-doped MgB2 wires and those of the nano-SiC-doped MgB2/Fe wires processed by the combination of in situ/ex situ methods.
Advanced Strategies for Stabilizing Single-Atom Catalysts for Energy Storage and Conversion
Publisher: Springer Science and Business Media LLC
Date: 09-2022
DOI: 10.1007/S41918-022-00169-Z
Abstract: Well-defined atomically dispersed metal catalysts (or single-atom catalysts) have been widely studied to fundamentally understand their catalytic mechanisms, improve the catalytic efficiency, increase the abundance of active components, enhance the catalyst utilization, and develop cost-effective catalysts to effectively reduce the usage of noble metals. Such single-atom catalysts have relatively higher selectivity and catalytic activity with maximum atom utilization due to their unique characteristics of high metal dispersion and a low-coordination environment. However, freestanding single atoms are thermodynamically unstable, such that during synthesis and catalytic reactions, they inevitably tend to agglomerate to reduce the system energy associated with their large surface areas. Therefore, developing innovative strategies to stabilize single-atom catalysts, including mass-separated soft landing, one-pot pyrolysis, co-precipitation, impregnation, atomic layer deposition, and organometallic complexation, is critically needed. Many types of supporting materials, including polymers, have been commonly used to stabilize single atoms in these fabrication techniques. Herein, we review the stabilization strategies of single-atom catalyst, including different synthesis methods, specific metals and carriers, specific catalytic reactions, and their advantages and disadvantages. In particular, this review focuses on the application of polymers in the synthesis and stabilization of single-atom catalysts, including their functions as carriers for metal single atoms, synthetic templates, encapsulation agents, and protection agents during the fabrication process. The technical challenges that are currently faced by single-atom catalysts are summarized, and perspectives related to future research directions including catalytic mechanisms, enhancement of the catalyst loading content, and large-scale implementation are proposed to realize their practical applications. Graphical Abstract Single-atom catalysts are characterized by high metal dispersibility, weak coordination environments, high catalytic activity and selectivity, and the highest atom utilization. However, due to the free energy of the large surface area, in idual atoms are usually unstable and are prone to agglomeration during synthesis and catalytic reactions. Therefore, researchers have developed innovative strategies, such as soft sedimentation, one-pot pyrolysis, coprecipitation, impregnation, step reduction, atomic layer precipitation, and organometallic complexation, to stabilize single-atom catalysts in practical applications. This article summarizes the stabilization strategies for single-atom catalysts from the aspects of their synthesis methods, metal and support types, catalytic reaction types, and its advantages and disadvantages. The focus is on the application of polymers in the preparation and stabilization of single-atom catalysts, including metal single-atom carriers, synthetic templates, encapsulation agents, and the role of polymers as protection agents in the manufacturing process. The main feature of polymers and polymer-derived materials is that they usually contain abundant heteroatoms, such as N, that possess lone-pair electrons. These lone-pair electrons can anchor the single metal atom through strong coordination interactions. The coordination environment of the lone-pair electrons can facilitate the formation of single-atom catalysts because they can enlarge the average distance of a single precursor adsorbed on the polymer matrix. Polymers with nitrogen groups are favorable candidates for dispersing active single atoms by weakening the tendency of metal aggregation and redistributing the charge densities around single atoms to enhance the catalytic performance. This review provides a summary and analysis of the current technical challenges faced by single-atom catalysts and future research directions, such as the catalytic mechanism of single-atom catalysts, sufficiently high loading, and large-scale implementation.

Integrating non‐targeted metabolomics and toxicology networks to study the mechanism of Esculentoside A‐induced hepatotoxicity in rats
Publisher: Wiley
Date: 31-03-2021
DOI: 10.1002/JBT.22761
Abstract: Esculentoside A (EsA) is a kind of triterpenoid saponins from the root tuber of Phytolacca acinosa Roxb. It has extensive medicinal activity, such as antibacterial, anti‐inflammatory, immune regulation, and cell proliferation inhibition. However, some researches suggested that EsA can cause hepatotoxicity, whose mechanism is not precise. To ensure the safety and reliability in the clinical use of Phytolacca acinosa Roxb., it is necessary to establish a rapid and accurate method to evaluate the toxicity, analyze and verify the toxicity mechanism of EsA. Therefore, this research explored the mechanism of hepatotoxicity induced by EsA in rats and analyzed endogenous metabolites' changes in rat plasma by combining network toxicology with non‐targeted metabolomics. We obtained 58 critical targets of EsA induced hepatotoxicity in rats based on the strategy of network toxicology, including albumin, mitogen‐activated protein kinase 1, Caspase‐3, etc. Many important pathways were obtained by Kyoto Encyclopedia of Genes and Genomes enrichment analysis, such as HIF‐1 signaling pathway, TNF signaling pathway, IL‐17 signaling pathway, and other concerning pathways. Sixteen biomarkers, including 5‐hydroxykynurenamine, N ‐acetylserotonin, palmitic acid, etc., were screened from rat plasma using Ultra‐performance liquid chromatography coupled with quadrupole time of flight mass spectrometry (UPLC‐Q‐TOF/MS), mainly involve Glycerophospholipid metabolism, Tryptophan metabolism, and other metabolic pathways. Further analysis showed that EsA may induce liver injury by activating oxidative stress and energy metabolism disorders, triggering inflammation and apoptosis.
Molecular dynamics study of water and ion behaviors of mixed salts solutions on extended quartz surface
Publisher: AIP Publishing
Date: 13-07-2022
DOI: 10.1063/5.0093885
Abstract: The adoption and evolution of water molecules and ions in mixed electrolytes at the surface play vital roles in the physical properties and chemical reactions of SiO2-like corrosion. The effect of salt type and concentration on the structure and dynamics of water molecules and ions at silica surfaces are studied using all-atom molecular dynamics simulations taking the case of the NaCl, MgCl2, and NaCl–MgCl2 aqueous solutions. The ability of ion hydration is in the order of Mg2+ & Na+ & Cl−, being opposite to their hydration Gibbs free energies, which directly influence the weak interaction in the solution and the diffusion rate of the particles. Mg shows stronger destruction to weak interactions than Na does, and ionic hydration of Mg2+ decelerates the self-diffusion coefficient of water molecules significantly due to the enhanced Coulomb effect and the interruption of solution continuity. Meanwhile, the self-diffusion coefficient of particles decreases with the concentration improvement in the single salt solution as increased ionic hydration. In the mixed salt solution, the order of diffusion rate is Cl− & Na+ & Mg2+ as a result of the different confinement effects of the protonated pore. Interestingly, a small amount of Na+ addition can promote the self-diffusion of Mg2+, but a great many of Na+ addition slows the diffusion of Mg2+. This work provides comprehensive insight into the behavior of mixed salt solutions at silica surfaces, shedding light on the practical applications of geological sciences, cultural relics protection, and colloidal sciences.
Nanoarchitectonics of La-Doped Ni3S2/MoS2 Hetetostructural Electrocatalysts for Water Electrolysis
Publisher: Wiley
Date: 12-07-2023
Abstract: MoS 2 with 2D structure shows efficient hydrogen evolution reaction (HER) performance because undercoordinated Mo–S edges have ideal hydrogen adsorption free energy. MoS 2 usually does not satisfy the bifunctional catalysts because of the poor intrinsic oxygen evolution reaction (OER) catalytic activity. Herein, it is proposed to construct heterostructure with OER active components to induce efficient bifunctional catalytic activity along with heteroatom doping to modify the electronic structure to optimize the adsorption and desorption capabilities of reaction intermediates. La‐doped Ni 3 S 2 /MoS 2 grown on nickel foam (La‐NMS@NF) is synthesized as bifunctional catalyst taking advantage of the excellent OER performance of Ni 3 S 2 . La‐NMS@NF evolves into nanoflower‐like structures with the addition of La dopant, which provides abundant pore channels to facilitate mass transfer and exposure of active sites. Density functional calculations reveal that the La‐doped Ni 3 S 2 /MoS 2 heterointerface can optimize the water adsorption and H * adsorption/desorption, improving the HER performance. The La‐NMS@NF exhibits an overpotential of 154 and 300 mV for HER and OER at 100 mA cm −2 in 1.0 m KOH. Herein, a heteroatom‐driven heterostructure activation strategy for electron rearrangement and structural evolution in electrocatalysts to decrease energy consumption in overall water splitting is demonstrated.

High critical current density of MgB2 bulks sintered in flowing welding grade ar atmosphere
Publisher: World Scientific Pub Co Pte Lt
Date: 10-07-2009
DOI: 10.1142/S0217979209062931
Abstract: The effect of processing atmosphere on the microstructure and superconducting properties of MgB 2 was studied for bulk s les made using the in situ reaction technique under argon gas with three different levels of purity: ultra-high, high, and welding grade. The critical temperature, T c , decreased by 0.5 K, while the full width at half maximum (FWHM) of the MgB 2 peaks, and the resistivity showed an increase in the s le processed in welding Ar . The critical current density, J c , and the upper critical field, H c 2 , for the welding Ar s le were improved in comparison with the s les treated in ultra-high and high purity argon. Optimal J c in MgB 2 can be achieved by using readily available and economical welding grade Ar as the protective atmosphere instead of using ultra-high or high purity Ar .

DOI: 10.1007/S40145-022-0632-0
Abstract: Orthorhombic perovskite oxides are studied by high-throughput first-principles calculations to explore new thermal barrier coating (TBC) materials with low thermal conductivities. The mechanical and thermal properties are predicted for 160 orthorhombic perovskite oxides. The average atomic volume is identified as a possible predictor of the thermal conductivity for the perovskite oxides, as it has a good correlation with the thermal conductivity. Five compounds, i.e., LaTmO 3 , LaErO 3 , LaHoO 3 , SrCeO 3 , and SrPrO 3 , having thermal conductivities under 1 W·m −1 ·K −1 and good damage tolerance, are proposed as novel TBC materials. The obtained data are expected to inspire the design of perovskite oxide-based TBC materials and also support their future functionality investigations.
Magnetic coupling in Mn3O4-coated γ-MnOOH nanowires
Publisher: Thomas Telford Ltd.
Date: 09-2018
Abstract: Mn 3 O 4 -coated γ-MnOOH nanowires were synthesized by using the hydrothermal method. X-ray diffraction and transmission electron microscopy studies reveal that the nanowires have a core (γ-MnOOH)–shell (Mn 3 O 4 ) structure. The magnetic transition temperature of Mn 3 O 4 is slightly lower than the previously reported value because of the increased thermal disturbance for nanomaterials and the influence of the helical magnetism of γ-MnOOH. The hysteresis loop at 50 K keeps the same shape as was measured below the Néel temperature of Mn 3 O 4 because of the short-range order of γ-MnOOH above the transition temperature. The short-range ordering is responsible for the deviation of the hysteresis loop at 300 K from the linear behavior of a normal paramagnetic phase. The magnetic coupling behavior between Mn 3 O 4 and γ-MnOOH also induces an exchange bias effect in the system. The hysteresis loop shifts to the positive direction with increasing measurement temperature. A lower barrier energy is requested for the reversal of magnetic moments on the interface to generate the exchange bias behavior because of the asymmetric magnetic natures of Mn 3 O 4 and γ-MnOOH, which should possess shorter responsive time compared with the traditional antiferromagnetic-ferromagnetic coupling induced exchange bias systems.

Thermodynamics of surface and oxygen vacancy in rare earth stannates by first‐principles calculations

DOI: 10.1111/JACE.19353
Abstract: The research of nanocrystalline pyrochlores highlights the importance of the surface structure, composition and segregated point defect in their thermal, electrical, optical, magnetic, and catalytic performances. In order to provide a basic view on the surface‐related phenomena, thermodynamic stabilities of three low‐index (100), (110), and (111) surfaces for A 2 Sn 2 O 7 ( A = La, Ce, Pr, Nd, Pm, Sm, Eu, or Gd), together with their configurations, electronic structures and related oxygen vacancies are investigated using first‐principles calculations. The (111) surfaces with A 3 SnO 8 and A Sn 3 O 6 terminations are predicted to be stable due to their low surface energies. Meanwhile, the (110) surfaces with A 2 Sn 2 O 8 and A 2 Sn 2 O 6 terminations are found to may also form. For these surface structures, the amount of broken bonds play the main role in their structural stability, and the local coordination environment variation also has minor contribution to it. Moreover, oxygen vacancies are observed to segregate on the surface layer, owing to lower energy of breaking bonds accompanying with oxygen vacancy formation and the larger relaxation space comparing to the counterpart in bulk. These results are expected to provide guidance on optimizing the performances of these compounds through surface engineering.

TC enhancement for nano-sic DOPED MgB2 superconductors sintered in 5t pulsed magnetic field
Publisher: World Scientific Pub Co Pte Ltd
Date: 10-07-2009
DOI: 10.1142/S0217979209062839
Abstract: The superconductivity of nano- SiC doped MgB 2 sintered in pulsed magnetic field (PMF) was investigated with Raman scattering measurements and Raman spectral fit analysis. The critical transition temperature, T c , for the s le sintered in 5T PMF is improved compared with that of the s le sintered without PMF. The high T c is attributed to the strengthening of the electron-phonon coupling (EPC) in MgB 2 , as reflected by the broadened E 2g mode in the Raman spectra. The EPC constants are estimated as 0.876 and 0.874, with the electron-E 2g coupling contribution 2.30 and 2.25, respectively. Magnetic field processing technology has been proved to be a powerful tool to improve the superconducting properties of SiC -doped MgB 2 superconductor.

Underwater self-cleaning scaly fabric membrane for oily water separation
Publisher: American Chemical Society (ACS)
Date: 10-02-2015
DOI: 10.1021/AM508814G
Abstract: Oily wastewater is always a threat to biological and human safety, and it is a worldwide challenge to solve the problem of disposing of it. The development of interface science brings hope of solving this serious problem, however. Inspired by the capacity for capturing water of natural fabrics and by the underwater superoleophobic self-cleaning property of fish scales, a strategy is proposed to design and fabricate micro/nanoscale hierarchical-structured fabric membranes with superhydrophilicity and underwater superoleophobicity, by coating scaly titanium oxide nanostructures onto fabric microstructures, which can separate oil/water mixtures efficiently. The microstructures of the fabrics are beneficial for achieving high water-holding capacity of the membranes. More importantly, the special scaly titanium oxide nanostructures are critical for achieving the desired superwetting property toward water of the membranes, which means that air bubbles cannot exist on them in water and there is ultralow underwater-oil adhesion. The cooperative effects of the microscale and nanoscale structures result in the formation of a stable oil/water/solid triphase interface with a robust underwater superoleophobic self-cleaning property. Furthermore, the fabrics are common, commercially cheap, and environmentally friendly materials with flexible but robust mechanical properties, which make the fabric membranes a good candidate for oil/water separation even under strong water flow. This work would also be helpful for developing new underwater superoleophobic self-cleaning materials and related devices.

Magnetic field processing to enhance critical current densities of MgB2 superconductors
Publisher: AIP Publishing
Date: 13-11-2006
DOI: 10.1063/1.2388126
Abstract: A magnetic field of up to 12T was applied during the sintering process of pure MgB2 and carbon nanotube (CNT) doped MgB2 wires. The authors have demonstrated that magnetic field processing results in grain refinement, homogeneity, and enhancement in Jc(H) and Hirr. The extent of improvement in Jc increases with increasing field. The Jc for a 10T field processed CNT doped s le increases by a factor of 3 at 10K and 8T and at 20K and 5T, respectively. Hirr for the 10T field processed CNT doped s le reached 9T at 20K, which exceeded the best value of SiC doped MgB2 at 20K. Magnetic field processing reduces the resistivity in CNT doped MgB2, straightens the entangled CNTs, and improves the adherence between CNTs and the MgB2 matrix.

Unveiling surface stability and oxygen diffusion of rare‐earth zirconate pyrochlores by density functional theory
Publisher: Wiley
Date: 22-12-2022
DOI: 10.1111/JACE.18920
Abstract: The surface structures, bond variations, and segregation of oxygen vacancies play crucial roles in the structural stability and functionality of nanocrystalline rare‐earth zirconate pyrochlores. In this work, the stabilities of (1 0 0), (1 1 0), and (1 1 1) surfaces of pyrochlore A 2 Zr 2 O 7 ( A = La, Ce, Pr, Nd, Pm, Sm, Eu, or Gd) are investigated by first‐principles calculations. Surface reconstruction occurs on (1 1 0) surface with a transition of ZrO 6 octahedron to ZrO 4 tetrahedron, leading to their large relaxation energies. In combination with the small amount of broken bonds during the surface formation process, the (1 1 0) surfaces are identified having the lowest surface formation energies than the (1 0 0) and (1 1 1) surfaces. Moreover, the reconstructed (1 1 0) surface has characteristics of the segregation of oxygen vacancies. The surface oxygen vacancies have the low migration barriers ( .2 eV), which are comparable with those in bulk and ensure the long‐distance diffusion of oxygen vacancies in A 2 Zr 2 O 7 . These discoveries provide fundamental insight to the surface structure and related oxygen vacancy behavior, which are expected to guide the optimization of the surface related properties for nanocrystalline rare‐earth zirconates.
Thermal-strain-induced enhancement of electromagnetic properties of SiC-MgB2 composites
Publisher: AIP Publishing
Date: 26-01-2009
DOI: 10.1063/1.3078396
Abstract: The effect of thermal strain caused by the different thermal expansion coefficients (α) of the MgB2 and SiC phases on the electromagnetic properties was studied for SiC–MgB2 composite, which was made by premixing SiC and B, followed by Mg diffusion and reaction. Thermal strain in the MgB2 phase was demonstrated with x-ray diffraction, Raman spectroscopy, and transmission electron microscopy. In contrast to the common practice of improving the critical current density Jc and the upper critical field Hc2 of MgB2 through chemical substitution, by taking advantage of residual thermal strains, we are able to design a composite showing only a small decrease in the critical temperature and a little increase in resistivity but a significant improvement over the Jc and Hc2 of pure MgB2.
Performance modulation of α-MnO 2 nanowires by crystal facet engineering
Publisher: Springer Science and Business Media LLC
Date: 11-03-2052
DOI: 10.1038/SREP08987
Abstract: Modulation of material physical and chemical properties through selective surface engineering is currently one of the most active research fields, aimed at optimizing functional performance for applications. The activity of exposed crystal planes determines the catalytic, sensory, photocatalytic and electrochemical behavior of a material. In the research on nanomagnets, it opens up new perspectives in the fields of nanoelectronics, spintronics and quantum computation. Herein, we demonstrate controllable magnetic modulation of α-MnO 2 nanowires, which displayed surface ferromagnetism or antiferromagnetism, depending on the exposed plane. First-principles density functional theory calculations confirm that both Mn- and O-terminated α-MnO 2 (1 1 0) surfaces exhibit ferromagnetic ordering. The investigation of surface-controlled magnetic particles will lead to significant progress in our fundamental understanding of functional aspects of magnetism on the nanoscale, facilitating rational design of nanomagnets. Moreover, we approved that the facet engineering pave the way on designing semiconductors possessing unique properties for novel energy applications, owing to that the bandgap and the electronic transport of the semiconductor can be tailored via exposed surface modulations.

Construction of CoNiFe Trimetallic Carbonate Hydroxide Hierarchical Hollow Microflowers with Oxygen Vacancies for Electrocatalytic Water Oxidation
Publisher: Wiley
Date: 06-2022
Abstract: It is of great challenge to design transition multimetallic carbonate hydroxides with delicate hollow features and defects for efficient electrolytic oxygen evolution reaction (OER). Here, a sequential self‐templating method to synthesize CoNiFe trimetallic carbonate hydroxide hierarchical hollow microflowers (CN‐xFe HMs) with oxygen vacancies (V O ) is reported. The synergistic merits of hollow structure, Fe substitution, and V O endow the CN‐xFe HMs with high active‐site exposure density and increased electrical conductivity. Specially, the optimized CN‐xFe HMs validate the excellent OER performance with an overpotential of 258 mV to drive 10 mA cm −2 and a Tafel slope of 48.7 mV dec −1 . Theoretical calculations reveal that Fe substitution and V O can synergistically regulate the electronic states to achieve near‐ideal adsorption/desorption capacity for oxygenated intermediates. Moreover, the successful synthesis of other six metals substituted CoNiM (M = Cu, Zn, Cr, Mo, Er and La) carbonate hydroxides provides a universal protocol to construct transition multimetallic electrocatalysts with hollow structures for gaining highly efficient energy conversion reactions.

Magnetic properties and magnetocaloric effect of (Mn1-x Nix) 3 Sn2 (x=0-0.5) compounds
Publisher: AIP Publishing
Date: 19-03-2009
DOI: 10.1063/1.3062953
Abstract: The effects of Ni substitution on the magnetic properties and magnetocaloric effect (MCE) of (Mn1−xNix)3Sn2 compounds (x=0–0.5) have been investigated by x-ray diffraction and magnetization measurements. It was found that Ni substitution decreases the crystal cell volume and the magnetic transition temperatures compared with pure Mn3Sn2. The MCE for all s les has been calculated from the magnetization data in terms of the isothermal magnetic entropy change ΔSM. The maximum values of ΔSMmax at the magnetic phase transition temperatures resulting from a change in magnetic field of ΔH=5 T were found to be 28.2 mJ/cm3 K for Mn3Sn2 (TC1∼257 K), increasing to 31.2 mJ/cm3 K for (Mn0.9Ni0.1)3Sn2 (TC∼167 K).
The effects of graphene doping on the in-field Jc of MgB2 wires
Publisher: American Scientific Publishers
Date: 02-2012
Abstract: The field and temperature dependence of the critical current density Jct were measured for both un-doped and graphene doped MgB2/Fe wires manufactured by 99.999% Crystalline Boron and 10% excess Magnesium (99%, 325 mesh). At 4.2 K and 10 T, Jct was estimated to be for the wire sintered at 800 degrees C for 30 minutes, the doped s le is almost improved as one order, compared with the best un-doped s le. At the same time, the temperature dependence of the upper critical field (Hc2) and the irreversibility field (Hirr) for the s les will also be included from the resistance (R)-temperature (T). A significant increase in the upper critical field is the main cause of the enhancement of the critical current density, Jct, in the high field region. The calculated active cross-sectional area fraction (A(F)) represents the connectivity factor between adjacent grains. This value is decreased with wire s les, which is why the improvement of transport Jct is lower than the improvement of magnetic Jcm in diffusion bulk s le.

The combined influence of connectivity and disorder on Jc and Tc performances in Mgx B2 +10 wt % SiC
Publisher: AIP Publishing
Date: 11-2009
DOI: 10.1063/1.3253757
Abstract: The influences of connectivity and disorder on the critical current density Jc are discussed to clarify the different mechanisms of Jc(H) enhancement in different magnetic field ranges. Excess Mg in MgxB2+10 wt % SiC composites effectively improves the connectivity, as evidenced by both the resistivity properties and the Raman scattering. The promising Jc(H) of Mg1.15B2+10 wt % SiC is attributed to both the high connectivity and the improved irreversibility field, Hirr, which is in agreement with the Raman fitting analysis. Raman scattering measurements suggest a strengthened electron-E2g coupling and weakened disorder with Mg addition.
