Complex study of electrophysical properties (the electrical resistivity r and the temperature coefficient of resistance (TCR) b) of thin-film samples based on ferromagnetic alloy Ni80Fe20 (permalloy) and noble metal Ag i...

Raman scattering investigations based on density functional theory (DFT) calculations were performed to explore the vibrational modes of wurtzite structured CdS nanoparticles (NPs). The calculations were performed to obt...

Localized plasmon resonance of a metal nanoantenna is determined by its size, shape and environment. Here, we diminish the size dependence by using multilayer metamaterials as epsilon-near-zero (ENZ) substrates. By means...

Populations of the South American sea lion (SASL, Otaria byronia) have been intensely exploited for leather and oil in different parts of its distribution range throughout the 19th and 20th centuries, generating large ch...

In this work, five substituted perovskite such as (Gd0.9Sr0.1) Mn0.8Co0.2O3, Tb0.8Sr0.2FeO3, Gd0.6Sr0.4RuO3, SrCe0.95Y0.05O3, and Mn0.6Co0.4SnO3 were synthesized by tartrate and hydroxide precursor method. The resulting ...

Abstract Background The population of China is aging rapidly. However, the long-term trajectories of functionally dependent late middle-aged and older Chinese people are currently absent. The present study aimed to estim...

The dependence of the polymerization and optical damage thresholds in multi-photon polymerization (MPP) lithography was studied using a broadly-tunable laser system with group delay dispersion (GDD) control. The order of...

Efficient coupling between optical fibers and on-chip photonic waveguides has long been a crucial issue for photonic chips used in various applications. Edge couplers (ECs) based on an inverse taper have seen widespread ...

The possibility of obtaining strongly degenerate (> 4×1020 сm-3) SnTe thin films (d = 200 - 2000 nm) with p-type conductivity by thermal evaporation in vacuum of SnTe crystals doped with Sb, with subsequent condensa...

Abstract The aim of this study is to show the laser field distribution dependence on the number of missing holes in the core of the photonic crystal fiber, so that three different structure of photonic crystal fibers (PC...

In this study, ordered mesoporous carbons CMK-3 were prepared by a nanocasting method using SBA-15 silica as template and sucrose as carbon source. The pure CMK-3 was modified with nickel by wet impregnation method and t...

This study investigates size-controlled, quantum-confined CdSe/ZnS core–shell quantum dots using core-hole clock spectroscopy in combination with post-collision interaction (PCI) line shape analysis, providing insights...

Based on the model of quantum flat rectangular and with infinitely high walls pit, the correspondences werecalculated and received value of the Fermi energy and kinetic coefficients (conductivity σ, Seebeck coefficient ...

Cerium-based materials were intensively studied in last years because of their high oxygen storage capacity (OSC) associated to the reversible Ce4+ Ce3+ process and their properties closely related to the defect chemistr...

The aim of this work was to create and study of ferrite nickel-cobalt powders, using sol-gel technology with participation of auto-combustion. Dependence of the initial permeability from the degree of substitution of cob...

The stress-strain response of pristine monolayer graphene under uniaxial loading/unloading over a more extensive size range (100 nm×100 nm) is studied by molecular dynamics simulations, which proves that graphene is p...

Abstract When simulating the process from elastic–plastic deformation, damage to failure in a metal structure collision, it is necessary to use the large shell element due to the calculation efficiency, but this would ...

The influence of sodium salts (chlorides, iodides, nitrates) on the behavior of nanosilica particles in aqueous medium was studied. The dependences of key physicochemical characteristics of the nanosilica/water/electroly...

Jamming and percolation of square objects of size k × k (k2-mers) isotropically deposited on simple cubic lattices have been studied bynumerical simulations complemented with finite-size scaling theory. The k2-mers were...

Abstract Given their attractiveness as a source of financing for the least developed countries, multilateral development banks (MDBs) have grown in quantity and size supported by their sources of financing. We believe th...

Mie resonances have recently attracted much attention in research on dielectric metasurfaces, owning to their enriched multipole resonances, negligible optical loss, and efficient light emitter integration. Although ther...

Superelasticity is a characteristic thermomechanical property in shape memory alloys (SMA), which is due to a reversible stress-induced martensitic transformation. Nano-compression experiments made possible the study of ...

This Campbell systematic review examines the effectiveness of 12‐step programs in reducing the use of illicit drugs. The review summarises findings from 10 studies, nine of which were conducted in the United States. Th...

Food waste (FW) in collective catering settings remains a critical barrier to sustainable food systems, due to its magnitude and multidimensional negative impacts. Food waste reduction and prevention measures are often d...
