In this study, an all-dielectric metasurface is proposed, whose unit cell is composed of a silicon elliptical disk and a silicon elliptical ring. The transmission of the structure were analyzed by using three-dimensional finite-difference time-domain method. In the wavelength range of 800 to 1200 nm, four sharp Fano r…
Abstract For a class of compatible profiles of initial data describing bulk phase regions separated by transition zones, we approximate the Cauchy problem of the Allen–Cahn (AC) phase field equation by an initial-boundary value problem in a bounded domain with the Dirichlet boundary condition. The initial-boundary val…
The mixed-spin Ising-Heisenberg and Heisenberg branched chains whose magnetic backbone consists of regularly alternating spins 1/2 and 5/2, the latter of which are additionally coupled to an extra spin 1/2 providing lateral branching, are investigated using exact analytical and density matrix renormalization group (DM…
Cancer is one of the leading causes of death worldwide. Regardless of advances in understanding the molecular mechanics of cancer, its treatment is still lacking and the death rates for many forms of the disease remain the same as six decades ago. Although a variety of therapeutic agents and strategies have been repor…
Simple and efficient synthesis of a nano-catalyst with an excellent catalytic property for hydrogen generation from hydrolysis of dimethyl amine-borane (DMAB) is a missing piece. Herein, effective and recycled palladium (Pd) nanoparticles (NPs) supported on soft nitriding porous carbon (NPC) are fabricated and applied…
Electrochemical reduction of CO 2 using solid oxide electrolysis cells (SOECs) has emerged as an attractive approach for converting CO 2 to high energy molecules, such as CO, a key precursor for the synthesis of fuels and chemicals using the commercially established Fischer–Tropsch process. The in situ generation of s…
We highlight the flexibility of two-dimensional (2D) materials for advancing current technologies through the introduction of 2D Raman thermography (2DRT). 2DRT combines monolayer materials and Raman spectroscopy to perform thermal imaging of micro- and nanodevices. In contrast to peak shift and line width based metho…
Controlled docking, merging, and welding of hollow structures at the nanoscale are essential in constructing sophisticated hollow systems in ways similar to plumbing and biosystems. To this end, regioselectivity is an important milestone demanding new tools. We bring the steric effect, a powerful regioselective method…
The review considers various complex mechanisms of isomorphism in the eudialyte-group minerals, involving both key positions of the heteropolyhedral framework and extra-framework components. In most cases, so-called blocky isomorphism is realized when one group of atoms and ions is replaced by another one, which is ac…
Abstract Studying local variations in the Seebeck coefficient of materials is important for understanding and optimizing their thermoelectric properties, yet most thermoelectric measurements are global over a whole device or material, thus overlooking spatial divergences in the signal and the role of local variation a…
Abstract Due to the good mechanical properties, flax fiber‐reinforced epoxy composites are being widely used as a green alternative to glass fiber composites. However, plant fibers absorb moisture from the environment, being in a higher moisture uptake as the relative humidity (RH) increases. This absorbed moisture de…
Smart insulin delivery platforms having the ability of mimicking pancreatic cells are highly expected for diabetes treatment. Herein, a smart glucose-sensitive insulin delivery platform on the basis of transcutaneous microneedles has been designed. The as-prepared microneedles are composed of glucose- and pH-responsiv…
Since collagen is naturally a main extracellular matrix protein, it has been applied widely in skin's tissue engineering scaffolds to mimics the characteristics of extracellular matrix for proper transplantation of living cells. However, there are challenges that come with application of this natural polymer such as h…
The current study unveils the variation of surface integrity aspects (micro-hardness, surface crack density, and surface characteristics) for Ni 55.95 Ti 44.05 shape memory alloy (SMA) with wire electric discharge machining (WEDM) process parameters, namely, pulse off time, wire tension, spark gap voltage, wire feed r…
Low-temperature NH 3 –SCR activity and high-temperature hydrothermal stability have always been recognized as two great challenges in the current developments of candidate NH 3 –SCR catalysts for practical applications. Herein, we present an optimizing solvent effects strategy to fabricate a WO 3 /SiO 2 @CeZrO x catal…
A correlation between Raman spectra of silicate glasses and their chemical composition is investigated using a collection of 31 natural multicomponent silicate glasses. The sample suite comprises the largest database of Raman spectra collected on natural volcanic materials and spans subalkaline to Na-rich and K-rich a…
The validity of the classical nucleation theory (CNT), the most important tool to describe and predict nucleation kinetics in supercooled liquids, has been at stake for almost a century. Here, we carried out comprehensive molecular dynamics simulations of the nucleation kinetics of a fast quenched supercooled germaniu…
Abstract InGaAs-based photodetectors have been generally used for detection in the short-wave infrared (SWIR) region. However, the epitaxial process used to grow these materials is expensive; therefore, InGaAs-based photodetectors are limited to space exploration and military applications. Many researchers have expend…
The on-surface synthesis of edge-functionalized graphene nanoribbons (GNRs) is challenged by the stability of the functional groups throughout the thermal reaction steps of the synthetic pathway. Edge fluorination is a particularly critical case in which the interaction with the catalytic substrate and intermediate pr…
Spacer fabrics are commonly used as cushioning materials. Their compression properties are one of the most important concerns in determining their specific end-use. Therefore, it is time and cost- efficient to have another means available that could allow quick and easy modifications to the compression behaviour of sp…
