Abstract: In this work, we report on significantly enhanced critical current density (Jc) in MgB2 superconductor that was easily obtained by doping with a hydrocarbon, highly active pyrene (C16H10), and using a sintering temperature as low as ∼600°C. The processing advantages of the C16H10 additive include production of a highly active carbon (C) source, an increased level of disorder, and the introduction of small grain size, resulting in enhancement of Jc.

DOI: 10.1063/1.2172558
Abstract: Electronic transport measurements have been carried out on superconducting MgB2∕Mg2Si multilayer film, using a standard four-probe method in perpendicular and parallel applied fields. The film, which was prepared by pulsed-laser deposition, has a layered structure with each MgB2 layer being 40–50 nm thick and the Mg2Si interlayers about 5 nm thick. The flux flow activation energy is deduced from the resistivity-temperature curves using an Arrhenius fit. The results show a clearly enhanced anisotropy of the vortex activation energy in the multilayered film. The irreversibility field and the vortex activation energy are significantly increased in parallel fields.

Abstract: In the last few decades, there is a global interest in micro products, and micro forming of metals is a promising micro manufacturing method. However, a comprehensive understanding of this process is absent. Therefore, this study aims to investigate micro deep drawing process via experimental and analysis work. Simulation results are in good agreement with the experimental data. The comparison between the finite element method (FEM) simulation and experimental results shows the feasibility of FEM simulation for micro deep drawing process. This research also lays a fundament of investigating micro forming process, especially micro deep drawing.

A data-driven approach to identify risk profiles and protective drugs in COVID-19
Publisher: Proceedings of the National Academy of Sciences
Date: 28-12-2020
Abstract: The global outbreak of COVID-19 infections generated an unprecedented need to develop novel therapeutic strategies. The SARS-CoV-2 virus enters host cells after binding to the angiotensin-converting enzyme 2 (ACE2), but whether renin−angiotensin−aldosterone system inhibitors (RAASi) are beneficial remains controversial. Standard statistical approaches may fail in assessing medications effects, due to multiple sources of bias in COVID-19 case series collected on an emergency basis. We present a data-driven approach to tackle these challenges. Multilayer risk stratifications were derived for assessing drugs effect, while Bayesian networks were estimated, to analyze dependencies among risk factors’ and treatments’ impact on survival. We provide strong evidence for protectivity of RAASi on hospitalized patients that call for randomized controlled trials of RAASi as COVID-19 treatment option.

Deformation behavior and wear resistance of hard TiCN and TiCN/Ti coatings on Ti6Al4V alloy
Publisher: Trans Tech Publications, Ltd.

DOI: 10.4028/WWW.SCIENTIFIC.NET/AMR.939.451
Abstract: Monolayer titanium carbide nitride (TiCN) and multilayer TiCN reinforced titanium (Ti) are coated on the surface of Ti6Al4V alloy by Filtered Arc Deposition System (FADS). Surface chemical composition has been characterized by an X-ray diffraction (XRD). Wear resistance of TiCN coating and TiCN/Ti coating have been detected by hommel tester T1000. Hardness and deformation mechanisms of the multilayer coatings are investigated using depth-sensing indentation comparison with the monolayer TiCN coatings. Focused Ion Beam (FIB) and Transmission Electron Microscopy (TEM) are used to identify the fracture modes of the coatings. The TEM image observations show that the inclined crack is the dominant crack in the monolayer TiCN coating while small bending crack is the dominant crack in the multilayer TiCN/Ti coating. The Ti layer with good ductility could efficiently suppress the crack propagation and absorb more indent energy.
Study on functions of chrome and fluoride ions in plating process of tin free steel by means of cyclic voltammetry
Publisher: Trans Tech Publications, Ltd.
Date: 11-2014
DOI: 10.4028/WWW.SCIENTIFIC.NET/MSF.773-774.557
Abstract: Plating solution of tin free steel (TFS) presents strong corrosion and special chemical action properties of chrome ions and fluoride ions. Electrochemistry behavior of their ions in the plating process of TFS was investigated by means of cyclic voltammetry (CV). The results show that hydrogen and oxygen evolution peaks can only be found in CV curves of the carbon anode in fluoride solution. CV curves of the carbon anode in chromium trioxide solution consist of five anodic peaks and two cathodic peaks. When fluoride ions are added into chrome ions solution, anodic peak disappears at peak potential of 1.18V. For CV curves of lead alloy anode, anodic peak can be found at peak potential of-0.2V in fluoride solution, and oxidation process is in asymmetry with reductive process in chromium trioxide solution or the mixed solution. As to CV curves of lead oxide anode, the current density of all peaks in chrome ions solution is lower compared with that of carbon anode and lead alloy anode. When fluoride ions are added into chrome ions solution, the current density of the oxidation process obviously decreases, while the absolute value of reductive process increase remarkably
Structurally stabilized mesoporous TiO2 nanofibres for efficient dye-sensitized solar cells
Publisher: AIP Publishing
Date: 09-2013
DOI: 10.1063/1.4820425
Abstract: One-dimensional (1D) TiO2 nanostructures are very desirable for providing fascinating properties and features, such as high electron mobility, quantum confinement effects, and high specific surface area. Herein, 1D mesoporous TiO2 nanofibres were prepared using the electrospinning method to verify their potential for use as the photoelectrode of dye-sensitized solar cells (DSSCs). The 1D mesoporous nanofibres, 300 nm in diameter and 10-20 μm in length, were aggregated from anatase nanoparticles 20-30 nm in size. The employment of these novel 1D mesoporous nanofibres significantly improved dye loading and light scattering of the DSSC photoanode, and resulted in conversion cell efficiency of 8.14%, corresponding to an ∼35% enhancement over the Degussa P25 reference photoanode.

Phase transformation and superconducting properties of MgB(2) using ball-milled low purity boron
Publisher: AIP Publishing
Date: 15-01-2008
DOI: 10.1063/1.2832752
Abstract: MgB 2 s les were prepared by using 96% boron (B) powder with strong crystalline phase that had been ball milled for various times. We observed s les that contained ball-milled 96% B in comparison with one made from as-supplied commercial 96% B, with the results showing a significant enhancement in the high field critical current density (Jc) due to small grain size and better reactivity. Specifically, many grain boundaries for MgB2 could be acting as strong flux pinning centers. Based on Rowell connectivity analysis, when the ball-milling time increased, the connectivity factor, described as the active cross-sectional area fraction (AF), was decreased. This implies that the intergrain connectivity became worse. These properties could lead to poor Jc in low field. However, the pinning force strength, Jc1/2×B1/4, of s les using ball-milled 96% B is larger than that of the reference s le using commercial 96% B powder. These results accompany enhanced irreversibility (Hirr) and upper critical fields (Hc2).

Abstract: Time-resolved magneto-optical studies are performed on MgB2 thin film s les grown by in situ pulsed laser deposition and in situ reactive deposition technique. The latter reveal dendritic avalanche-free flux penetration. The kinetic roughening of magnetic flux penetration is studied for applied ac current. Dynamic scaling laws determined for both static field and ac current are consistent with the directed percolation depinning model, placing the vortex dynamics in MgB2 in the same universality class as YBCO and Nb.

Novel chromium-free technologies for the prevention of wet stack corrosion on hot dipped metallic coatings: A review
Publisher: Association for Materials Protection and Performance (AMPP)
Date: 31-03-2018
DOI: 10.5006/2772
Abstract: Advances in novel corrosion prevention technologies, including organic-inorganic hybrid sol-gel coatings, ultra violet radiation curable coatings, rare earth metal corrosion inhibitors, and other additions for the fabrication of smart coatings, and their potential application to hot dipped metallic coated steel strip products have been reviewed. Rather than exploring the prevention of atmospheric corrosion as in similar publications in the field, the authors have instead placed emphasis on the feasibility of the technologies for protection against “wet stack corrosion,” also known as wet storage staining. Such corrosion of hot dipped metallic coatings is a common problem in industry, but one rarely explored in academia.

Indigenous social exclusion to inclusion: Case studies on Indigenous nursing leadership in four high income countries
Publisher: Wiley
Date: 04-05-2021
DOI: 10.1111/JOCN.15801
Abstract: This discursive paper provides a call to action from an international collective of Indigenous nurse academics from Australia, Canada, Aotearoa New Zealand and the USA, for nurses to be allies in supporting policies and resources necessary to equitably promote Indigenous health outcomes. Indigenous Peoples with experiences of colonisation have poorer health compared to other groups, as health systems have failed to address their needs and preferences. Achieving health equity will require leadership from Indigenous nurses to develop and implement new systems of care delivery. However, little is known about how Indigenous nurses influence health systems as levers for change. A Kaupapa Māori case study design. Using a Kaupapa Māori case study methodology, coupled with expert Indigenous nursing knowledge, we developed a consensus on key themes. Themes were derived from three questions posed across the four countries. Themes were collated to illustrate how Indigenous nurses have provided nursing leadership to redress colonial injustices, contribute to models of care and enhance the Indigenous workforce. These case studies highlight Indigenous nurses provide strong leadership to influence outcomes for Indigenous Peoples. Five strategies were noted across the four countries: (1) Indigenous nationhood and reconciliation as levers for change, (2) Indigenous nursing leadership, (3) Indigenous workforce strategies, (4) Development of culturally safe practice and Indigenous models of care and (5) Indigenous nurse activism. In light of 2020 declared International Year of the Nurse and Midwife , we assert Indigenous nurses’ work must be visible to support development of strategic approaches for improving health outcomes, including resources for workforce expansion and for implementing new care models. Curating strategies to promote Indigenous nurse leaders around the world is essential for improving models of healthcare delivery and health outcomes for Indigenous Peoples.

DOI: 10.1142/S0219581X12400388
Abstract: Fluorescent semiconductor nanocrystals have been widely used as fluorescent materials in chemical sensors, biotechnology, medical diagnostics, biological imaging and many other fields. Compared to the conventional organic fluorophores, the inorganic quantum dots (QDs) have many advantages, including broad absorption spectra, narrow emission spectra, good photostability and long fluorescent lifetime after excitation. Here, the high quality CdS QDs were synthesized directly from sulfur and CdO using the paraffin liquid as solvent and the oleic acid as the reacting media. The synthesized CdS QDs with a zinc blende (cubic) crystal structure were proved by X-ray diffraction. HRTEM observation revealed that the CdS QDs were uniform and the average grain size was about 4 nm. The optical properties of the CdS QDs were characterized by using photoluminescence (PL) spectrophotometer and Ultraviolet-visible (UV-Vis) absorption spectrophotometer. The formation mechanism of CdS QDs in the paraffin liquid and oleic acid system was proposed.

Cytocompatible tantalum films on Ti6Al4V substrate by filtered cathodic vacuum arc deposition
Publisher: Elsevier BV
Date: 08-2018
DOI: 10.1016/J.BIOELECHEM.2018.02.006
Abstract: Tantalum films were deposited on negatively biased Ti6Al4V substrates using filtered cathodic vacuum arc deposition to enhance the corrosion resistance of the Ti6Al4V alloy. The effect of substrate voltage bias on the microstructure, mechanical and corrosion properties was examined and the cytocompatibility of the deposited films was verified with mammalian cell culturing. The Ta films deposited with substrate bias of -100V and -200V show a mixture of predominantly β phase and minority of α phase. The Ta/-100V film shows adhesive failure at the Ti/Ta interface and a cohesive fracture is observed in Ta/-200V film. The Ta/-100V showed a significant improvement in corrosion resistance, which is attributed to the stable oxide layer. The in-vitro cytocompatibility of the materials was investigated using rat bone mesenchymal stem cells, and the results show that the Ta films have no adverse effect on mammalian cell adhesion and spreading proliferation.

The value and cost of complexity in predictive modelling: role of tissue anisotropic conductivity and fibre tracts in neuromodulation
Publisher: IOP Publishing
Date: 16-04-2014
DOI: 10.1088/1741-2560/11/3/036002
Abstract: Computational methods are increasingly used to optimize transcranial direct current stimulation (tDCS) dose strategies and yet complexities of existing approaches limit their clinical access. Since predictive modelling indicates the relevance of subject athology based data and hence the need for subject specific modelling, the incremental clinical value of increasingly complex modelling methods must be balanced against the computational and clinical time and costs. For ex le, the incorporation of multiple tissue layers and measured diffusion tensor (DTI) based conductivity estimates increase model precision but at the cost of clinical and computational resources. Costs related to such complexities aggregate when considering in idual optimization and the myriad of potential montages. Here, rather than considering if additional details change current-flow prediction, we consider when added complexities influence clinical decisions. Towards developing quantitative and qualitative metrics of value/cost associated with computational model complexity, we considered field distributions generated by two 4 × 1 high-definition montages (m1 = 4 × 1 HD montage with anode at C3 and m2 = 4 × 1 HD montage with anode at C1) and a single conventional (m3 = C3-Fp2) tDCS electrode montage. We evaluated statistical methods, including residual error (RE) and relative difference measure (RDM), to consider the clinical impact and utility of increased complexities, namely the influence of skull, muscle and brain anisotropic conductivities in a volume conductor model. Anisotropy modulated current-flow in a montage and region dependent manner. However, significant statistical changes, produced within montage by anisotropy, did not change qualitative peak and topographic comparisons across montages. Thus for the ex les analysed, clinical decision on which dose to select would not be altered by the omission of anisotropic brain conductivity. Results illustrate the need to rationally balance the role of model complexity, such as anisotropy in detailed current flow analysis versus value in clinical dose design. However, when extending our analysis to include axonal polarization, the results provide presumably clinically meaningful information. Hence the importance of model complexity may be more relevant with cellular level predictions of neuromodulation.

Rational Design of 3D Dendritic TiO2 Nanostructures with Favorable Architectures
Publisher: American Chemical Society (ACS)
Date: 10-11-2011
DOI: 10.1021/JA208468D
Abstract: Controlling the morphology and size of titanium dioxide (TiO(2)) nanostructures is crucial to obtain superior photocatalytic, photovoltaic, and electrochemical properties. However, the synthetic techniques for preparing such structures, especially those with complex configurations, still remain a challenge because of the rapid hydrolysis of Ti-containing polymer precursors in aqueous solution. Herein, we report a completely novel approach-three-dimensional (3D) TiO(2) nanostructures with favorable dendritic architectures-through a simple hydrothermal synthesis. The size of the 3D TiO(2) dendrites and the morphology of the constituent nano-units, in the form of nanorods, nanoribbons, and nanowires, are controlled by adjusting the precursor hydrolysis rate and the surfactant aggregation. These novel configurations of TiO(2) nanostructures possess higher surface area and superior electrochemical properties compared to nanoparticles with smooth surfaces. Our findings provide an effective solution for the synthesis of complex TiO(2) nano-architectures, which can pave the way to further improve the energy storage and energy conversion efficiency of TiO(2)-based devices.

Abstract: We obtained a MgB2∕Mg2Si multilayer structure by sequentially switching a stoichiometric MgB2 target and a Si target during off-axis pulsed-laser deposition. The transmission-electron-microscopic cross-sectional image of the resulting film exhibits a layered structure with each MgB2 layer being 40–50nm thick and the Mg2Si interlayers about 5nm thick. A clearly enhanced anisotropy in the irreversibility lines and the vortex activation energy was observed. Pinning and the flux flow activation energy are significantly increased in parallel applied fields.

Abstract: Triboelectric nanogenerators (TENGs) can convert amorphous mechanical energy into electrical energy and solve the issue of source power for biological electronics implanted in the human body. Biomedical metal Ti was selected as the bottom plate, to fabricate a TENG with a poly-L-lactic-acid (PLLA) Ti structure. The Ti sheets were treated with a two-step anodization method, and the growth of titanium dioxide nanotube arrays (TNTAs) was controlled by variation in anodic oxidation time. The results showed that the output voltage and current of the PLLA-TNTAs biocompatible triboelectric nanogenerator (BCTENG), prepared by the two-step anodization method under 60 V for 6 h, can reach 220.6 V and 15.1 μA, respectively. The output voltage and current increased by 96.3% and 91.1%, respectively, compared with TENGs prepared without using the anode oxidation method. The choice of materials and modification of the surface morphology of the TENG components was found to be critical for increasing the triboelectrically generated surface charge. The output of the BCTENG can regulate degradation of magnesium alloys freely by using cathodic protection.
In-field Jc improvement by oxygen-free pyrene gas diffusion into highly dense MgB2 superconductor

DOI: 10.1063/1.3532033
Abstract: Oxygen-free pyrene gas as a carbon (C) dopant was delinked and incorporated into highly dense MgB2 structure via a gas phase diffusion method. The technique offers the advantages that molecular C is homogeneously distributed into MgB2 and substituted at the boron sites without any severe deterioration of grain connectivity. The C substitution causes a significant shrinkage of the a-lattice parameter and an increase in the lattice strain, resulting in high disorder. The introduction of structural disorder as a result of C doping leads to a considerable enhancement of the in-field critical current density (Jc) and upper critical field.
Fabrication of biodegradable HA/Mg-Zn-Ca composites and the impact of heterogeneous microstructure on mechanical properties, in vitro degradation and cytocompatibility

Abstract: Due to their desirable elastic modulus and density that are similar to natural bone, non-toxic element containing magnesium alloys are regarded as promising bio-degradable materials. A biodegradable HA-particle-reinforced magnesium-matrix composite Mg-3Zn-0.2Ca-1HA (wt%) was fabricated for biomedical application by a combination of high shear solidification (HSS) and hot extrusion technology. The microstructure, mechanical properties, corrosion resistance and cell biocompatibility of the composite were subsequently investigated. In comparison with the matrix alloy, the as-cast Mg-3Zn-0.2Ca-1HA composite obtained by HSS technology exhibited a uniform and fine grained structure, further refined after a hot extrusion ratio of 36:1. The yield strength (0.2%YS), ultimate tensile strength and elongation of the extruded composite were 322 MPa, 341 MPa and 7.6%, respectively. The corrosion rate of the as-extruded Mg-3Zn-0.2Ca-1HA composite was measured to be 1.52 mm/y. Electrochemical and immersion tests showed that the corrosion resistance of the composite is slightly improved comparing to that of the matrix alloy.
