AbstractNonlinear-optical response of photorefractive hybrid liquid crystal (LC) cells has been studied by means of dynamic holographic technique in two-wave mixing arrangement. The LC cells include nonuniform silicon substrates comprising a micrometer-range photonic crystal. A thin LC layer is set

AbstractThis paper reports on experimental and theoretical investigations of atypical temperature-dependent photoluminescence properties of multi-stacked InAs quantum dots in close proximity to InGaAs strain-relief underlying quantum well. The InAs/InGaAs/GaAs QD heterostructure was grown by solid-s

AbstractThe synergy between noble metal nanoparticles—known for their plasmonic and electrocatalytic prowess—and electrospun polymer nanofibers—renowned for their exceptional mechanical and thermal attributes—has spawned hybrid systems with unprecedented functionality. This review surveys recent str

AbstractWe fabricated black silicon (BS) using a nanosecond pulsed laser (ns‑laser) under vacuum or in an oxygen atmosphere. Remarkably, room‑temperature photoluminescence (PL) measurements reveal strong visible emission from the BS surface after annealing. A pronounced lasing peak near 600 nm appea

AbstractWe investigated the corrosion behaviour of high‑purity nanopowders (91.8–97.6 % main phase, 32–78 nm average size) of borides and carbides of IV–VIB group metals, plus silicon carbide, in standard nickel‑electrolyte baths. Corrosion resistance was quantified as a function of electrolyte pH,

AbstractAntibiotic resistance remains a critical global health challenge, driven by bacterial adaptations such as drug modification, target alteration, reduced permeability, and active extrusion via efflux pumps. These pumps not only expel antibiotics but also regulate quorum‑sensing molecules that

AbstractWe report a highly sensitive, non‑enzymatic approach for uric acid (UA) determination that leverages visible‑light illumination on a glassy carbon electrode (GCE) modified by electrodeposited gold nanoparticles (AuNPs). Scanning electron microscopy (SEM) confirmed that the AuNPs are well‑dis

AbstractSubstitutional doping introduces tailored atomic impurities into host materials, potentially enhancing their properties. Yet, the structural and electronic evolution of natural nanoclay minerals upon metal doping remains poorly understood. Here we report a facile lanthanum (La) doping protoc

AbstractThree‑dimensional graphene networks (3DGN) offer a continuous, high‑quality scaffold that can enhance TiO₂ photocatalysts. However, the limited defect density of 3DGN hampers both intimate contact with TiO₂ nanoparticles—critical for efficient electron transfer—and the adsorption of pollutan

AbstractCarbon-coated silica nanoparticles anchored on multi-walled carbon nanotubes (SiO2@C/MWNT composite) were synthesized via a simple and facile sol-gel method followed by heat treatment. Scanning and transmission electron microscopy (SEM and TEM) studies confirmed densely anchoring the carbon-

AbstractA Sb/palygorskite (PAL) composite was synthesized by a facile solvothermal process and applied in catalytic hydrogenation of p-nitrophenol for the first time. It was found that the Sb nanoparticles with the sizes of 2–5 nm were well dispersed on the fiber of PAL, while partial aggregated Sb

AbstractA dual‑responsive copolymer based on an N-vinylamide backbone was engineered to combine thermal and photo‑responsiveness. A methoxyethyl substituent was introduced to enhance hydrophilicity, while azobenzene units were grafted to impart light sensitivity. The resulting polymer, N-(methoxyeth

AbstractIn this paper, ultra-long copper nanowires (CuNWs) were successfully synthesized at a large scale by hydrothermal reduction of divalent copper ion using oleylamine and oleic acid as dual ligands. The characteristic of CuNWs is hard and linear, which is clearly different from graphene nanopla

AbstractWe report the first synthesis of porous and hollow LiNb3O8 anode material using a hydrothermal‑assisted sintering route. The phase evolution and structure‑forming mechanism were elucidated. The unique porous‑hollow morphology originates from local liquid‑phase formation caused by lithium vol

Abstract\nThe coupling between structural phase transformations and dislocation dynamics complicates the understanding of cerium’s nanoscale deformation. Here we employ molecular dynamics (MD) to unravel the mechanism of cerium during ultra‑precision diamond cutting. An MD model incorporating empiri

Abstract A compact metamaterial absorber (MA) based on a hexagonal array of titanium nitride (TiN) nano‑disks and a monolayer of molybdenum disulfide (MoS₂) has been designed and optimized using finite‑difference time‑domain (FDTD) simulations. The stack TiN/SiO₂/Al, with a 0.625 nm MoS₂ layer posit

AbstractHerein, folic acid (FA) conjugated Poly(d,l-lactide-co-glycolide) (PLGA)-lipid composites (FA-PL) were developed as nanocarriers for the targeted delivery of insoluble anti-cancer drug paclitaxel (PTX), resulting FA-PLP nanoparticles. Furthermore, 131I, as a radioactive tracer, was used to l

Abstract Lead‑free perovskite solar cells based on formamidinium tin triiodide (FASnI₃) and cesium tin triiodide (CsSnI₃) offer a sustainable alternative to conventional lead‑containing devices. In this work, we integrate solvent engineering with an anti‑solvent dripping technique to produce perovsk

AbstractWe investigated the structural and photoluminescence (PL) properties of poly(3‑hexylthiophene) (P3HT) thin films with molecular weights (MWs) of 3 000 and 13 300. While high‑MW P3HT invariably adopts a single lamellar packing (form I), low‑MW P3HT can crystallize into either form I or the al

AbstractWe examined how sulfate anions affect the synthesis of nanodispersed TiO₂ via TiCl₄ hydrolysis. The data indicate that the formation of both chelating and bridging bidentate complexes between sulfate and octahedrally coordinated titanium hydroxide monomers governs anatase phase nucleation.Ba
