Structural tunability in metamaterials

DOI: 10.1063/1.3211920
Abstract: We propose an efficient approach for tuning the transmission characteristics of metamaterials through a continuous adjustment of the lattice structure and confirm it experimentally in the microwave range. The concept is rather general and applicable to various metamaterials as long as the effective medium description is valid. The demonstrated continuous tuning of a metamaterial response is highly desirable for a number of emerging applications of metamaterials, including sensors, filters, and switches, realizable in a wide frequency range.

Detection of the local H+ gradients on the internal mitochondrial membrane

DOI: 10.1016/S0014-5793(98)01463-X
Abstract: Respiration-dependent responses of a pH probe (fluorescein isothiocyanate, FITC), covalently bound to the membrane proteins of mitochondria and submitochondrial particles (SMP) have been studied. A spectral shift indicating FITC deprotonation was observed when respiration was activated in coupled mitochondria. Such a response was increased by valinomycin and reduced by uncoupler. Some FITC deprotonation was detected in the presence of excess of an uncoupler, but the response was smaller and insensitive to valinomycin. FITC deprotonation was also observed in submitochondrial particles after succinate addition. In this case it was not affected by uncoupler. Increase in the buffer concentration was found to (i) decrease the FITC response and (ii) increase the rate of uncoupled respiration in both mitochondria and submitochondrial particles. The results are consistent with the assumption that respiration initiates appearance of local H+ activity gradients on the inner side of the internal mitochondrial membrane during the steady-state H+ pumping. We suggest that the formation of this gradient is due to kinetic barrier to proton transfer from the bulk phase to the respiratory proton pump vicinity.

Abstract: The successful fabrication and experimental verification of a novel metamaterial based on flexible metallic helices is reported. The helices undergo compression under the influence of incident radiation, demonstrating a nonlinear chiral electromagnetic response, associated with the power-dependent change in the helix pitch. This design is promising for application to power-dependent polarization rotation of propagating waves.

Tailoring spontaneous infrared emission of HgTe quantum dots with laser-printed plasmonic arrays
Publisher: Springer Science and Business Media LLC

DOI: 10.1038/S41377-020-0247-6
Abstract: Chemically synthesized near-infrared to mid-infrared (IR) colloidal quantum dots (QDs) offer a promising platform for the realization of devices including emitters, detectors, security, and sensor systems. However, at longer wavelengths, the quantum yield of such QDs decreases as the radiative emission rate drops following Fermi’s golden rule, while non-radiative recombination channels compete with light emission. Control over the radiative and non-radiative channels of the IR-emitting QDs is crucially important to improve the performance of IR-range devices. Here, we demonstrate strong enhancement of the spontaneous emission rate of near- to mid-IR HgTe QDs coupled to periodically arranged plasmonic nanoantennas, in the form of nanobumps, produced on the surface of glass-supported Au films via ablation-free direct femtosecond laser printing. The enhancement is achieved by simultaneous radiative coupling of the emission that spectrally matches the first-order lattice resonance of the arrays, as well as more efficient photoluminescence excitation provided by coupling of the pump radiation to the local surface plasmon resonances of the isolated nanoantennas. Moreover, coupling of the HgTe QDs to the lattice plasmons reduces the influence of non-radiative decay losses mediated by the formation of polarons formed between QD surface-trapped carriers and the IR absorption bands of dodecanethiol used as a ligand on the QDs, allowing us to improve the shape of the emission spectrum through a reduction in the spectral dip related to this ligand coupling. Considering the ease of the chemical synthesis and processing of the HgTe QDs combined with the scalability of the direct laser fabrication of nanoantennas with tailored plasmonic responses, our results provide an important step towards the design of IR-range devices for various applications.

GPD1 Specifically Marks Dormant Glioma Stem Cells with a Distinct Metabolic Profile
Publisher: Elsevier BV
Date: 08-2019
DOI: 10.1016/J.STEM.2019.06.004
Abstract: Brain tumor stem cells (BTSCs) are a chemoresistant population that can drive tumor growth and relapse, but the lack of BTSC-specific markers prevents selective targeting that spares resident stem cells. Through a ribosome-profiling analysis of mouse neural stem cells (NSCs) and BTSCs, we find glycerol-3-phosphate dehydrogenase 1 (GPD1) expression specifically in BTSCs and not in NSCs. GPD1 expression is present in the dormant BTSC population, which is enriched at tumor borders and drives tumor relapse after chemotherapy. GPD1 inhibition prolongs survival in mouse models of glioblastoma in part through altering cellular metabolism and protein translation, compromising BTSC maintenance. Metabolomic and lipidomic analyses confirm that GPD1

The experience of lung cancer in Aboriginal and Torres Strait Islander peoples and what it means for policy, service planning and delivery
Publisher: CSIRO Publishing
Date: 2013
DOI: 10.1071/AH10955
Abstract: Background. Aboriginal and Torres Strait Islander peoples experience inferior outcomes following diagnosis of lung cancer. Aim. To examine the experience of lung cancer in this population and identify reasons for poorer outcomes and lower levels of treatment compared with non-Aboriginal and Torres Strait Islander peoples, and opportunities for early intervention. Method. Literature was sought via electronic database searches and journal hand-searching for the period from January 1995 to July 2010. Databases used included Indigenous HealthInfoNet, SCOPUS, PsycInfo, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medline, HealthInsite and Google Scholar. Findings. Exposure to risk factors, cultural and spiritual values, remoteness and geographic characteristics, entrenched socioeconomic inequalities and racism contribute to reduced service access and poor outcomes. The review highlighted a complex interplay of in idual, social, health system and environmental factors that impact on optimal lung cancer care and lung cancer outcomes. Considering the burden of lung cancer within a framework of social determinants of health is necessary for policy-making and service planning and delivery. Conclusions. It is imperative that the disproportionate burden of lung cancer in Aboriginal and Torres Strait Islander peoples is addressed immediately. Whilst strategic interventions in lung cancer prevention and care are needed, service providers and policy makers must acknowledge the entrenched inequality that exists and consider the broad range of factors at the patient, provider and system level. Primary care strategies and health promotion activities to reduce risk factors, such as smoking, must also be implemented, with Aboriginal and Torres Strait Islander peoples’ engagement and control at the core of any strategy. This review has indicated that multifaceted interventions, supported by enabling policies that target in iduals, communities and health professionals, are necessary to improve lung cancer outcomes and disparities. What is known about the topic? Aboriginal Australians suffer a disproportionate burden of ill health including poor outcomes from lung cancer. What does this paper add? This paper reports the outcomes of an integrative literature review. The paper identifies potential barriers to optimal lung cancer care and management for Aboriginal Australians. This paper describes barriers within the context of in idual beliefs and behaviours, healthcare systems issues and environmental issues. The authors conclude that acknowledging entrenched inequality and addressing factors at the patient, provider and system level are needed to reduce the lung cancer burden in Aboriginal Australians. What are the implications for practitioners? This paper highlights the need for a greater focus on lung cancer care, awareness and diagnosis within the Aboriginal Australian population. Addressing culturally appropriate smoking-cessation initiatives is of particular importance. Primary care practitioners are key to reducing the burden of lung cancer in Aboriginal Australians.

On the applications of metamaterial lenses for magnetic resonance imaging
Publisher: Elsevier BV

DOI: 10.1016/J.JMR.2009.12.005
Abstract: In this work some possible applications of negative permeability magnetic metamaterial lenses for magnetic resonance imaging (MRI) are analyzed. It is shown that using magnetic metamaterials lenses it is possible to manipulate the spatial distribution of the radio-frequency (RF) field used in MR systems and, under some circumstances, improve the sensitivity of surface coils. Furthermore a collimation of the RF field, phenomenon that may find application in parallel imaging, is presented. MR images of real tissues are shown in order to prove the suitability of the theoretical analysis for practical applications.

New avenues for phase matching in nonlinear hyperbolic metamaterials
Publisher: Springer Science and Business Media LLC
Date: 11-03-2015
DOI: 10.1038/SREP08983
Abstract: Nonlinear optical processes, which are of paramount importance in science and technology, involve the generation of new frequencies. This requires phase matching to avoid that light generated at different positions interferes destructively. Of the two original approaches to achieve this, one relies on birefringence in optical crystals and is therefore limited by the dispersion of naturally occurring materials, whereas the other, quasi-phase-matching, requires direct modulation of material properties, which is not universally possible. To overcome these limitations, we propose to exploit the unique dispersion afforded by hyperbolic metamaterials, where the refractive index can be arbitrarily large. We systematically analyse the ensuing opportunities and demonstrate that hyperbolic phase matching can be achieved with a wide range of material parameters, offering access to the use of nonlinear media for which phase matching cannot be achieved by other means. With the rapid development in the fabrication of hyperbolic metamaterials, our approach is destined to bring significant advantages over conventional techniques for the phase matching of a variety of nonlinear processes.
Broadband isotropic μ-near-zero metamaterials

Date: 18-11-2013
DOI: 10.1063/1.4832056
Abstract: Natural diamagnetism, while being a common phenomenon, is limited to permeability values close to unity. Artificial diamagnetics, to the contrary, can be engineered to provide much lower values and may even possess an effective permeability close to zero. In this letter, we provide an experimental confirmation of the possibility to obtain extremely low permeability values by manufacturing an isotropic metamaterial composed of conducting cubes. We show that the practical assembly is quite sensitive to fabrication tolerances and demonstrate that permeability of about μ=0.15 is realisable.

Magnetoelastic metamaterials

DOI: 10.1038/NMAT3168
Abstract: The study of advanced artificial electromagnetic materials, known as metamaterials, provides a link from material science to theoretical and applied electrodynamics, as well as to electrical engineering. Being initially intended mainly to achieve negative refraction, the concept of metamaterials quickly covered a much broader range of applications, from microwaves to optics and even acoustics. In particular, nonlinear metamaterials established a new research direction giving rise to fruitful ideas for tunable and active artificial materials. Here we introduce the concept of magnetoelastic metamaterials, where a new type of nonlinear response emerges from mutual interaction. This is achieved by providing a mechanical degree of freedom so that the electromagnetic interaction in the metamaterial lattice is coupled to elastic interaction. This enables the electromagnetically induced forces to change the metamaterial structure, dynamically tuning its effective properties. This concept leads to a new generation of metamaterials, and can be compared to such fundamental concepts of modern physics as optomechanics of photonic structures or magnetoelasticity in magnetic materials.

Analysis of the resolution of split-ring metamaterial lenses with application in parallel magnetic resonance imaging
Publisher: AIP Publishing
Date: 03-01-2011
DOI: 10.1063/1.3533394
Abstract: In this work, we experimentally determine the resolution of split-ring metamaterials lenses with emphasis in magnetic resonance imaging applications. Two small sources are used to determine the minimal resolution of the lens, which is compared with previous theoretical predictions. Taking into account this minimal resolution, a second experiment is designed in order to study the ability of a split-ring lens to improve the localization of the field produced by two closely spaced coils. This ability could find application in parallel magnetic resonance imaging, which take advantage of the distinct coil sensitivities in order to reduce the image acquisition time.

Spontaneous chiral symmetry breaking in metamaterials
Publisher: Springer Science and Business Media LLC
Date: 18-07-2014
DOI: 10.1038/NCOMMS5441
Abstract: Spontaneous chiral symmetry breaking underpins a variety of areas such as subatomic physics and biochemistry, and leads to an impressive range of fundamental phenomena. Here we show that this prominent effect is now available in artificial electromagnetic systems, enabled by the advent of magnetoelastic metamaterials where a mechanical degree of freedom leads to a rich variety of strong nonlinear effects such as bistability and self-oscillations. We report spontaneous symmetry breaking in torsional chiral magnetoelastic structures where two or more meta-molecules with opposite handedness are electromagnetically coupled, modifying the system stability. Importantly, we show that chiral symmetry breaking can be found in the stationary response of the system, and the effect is successfully demonstrated in a microwave pump-probe experiment. Such symmetry breaking can lead to a giant nonlinear polarization change, energy localization and mode splitting, which provides a new possibility for creating an artificial phase transition in metamaterials, analogous to that in ferrimagnetic domains.
