AbstractPt‑based alloys are widely adopted in polymer electrolyte membrane fuel cells (PEMFCs) due to their superior oxygen reduction reaction (ORR) activity. However, anion adsorption—particularly from bisulfate (HSO4−) and sulfate (SO42−)—can markedly diminish performance. In this study, we employ

AbstractWe report a highly sensitive, low‑cost electrochemical sensor for liquid ethanol based on mesoporous α‑Fe₂O₃ decorated with sub‑20 nm Ag nanoparticles. The hybrid nanostructure was prepared via a modified sol‑gel route using Pluronic F‑127 as a template, followed by photochemical reduction o

Abstract In this paper, we present a comprehensive theoretical model and 2‑D simulation of InGaAs/InAlAs SAGCM avalanche photodiodes (APDs). We examine how the charge‑layer design and tunneling phenomena influence electric‑field distribution, multiplication factor, and dark‑current characteristics.

Abstract We report a sustainable route to produce gold (Au), platinum (Pt), palladium (Pd), silver (Ag) and copper‑oxide (CuO) nanoparticles (NPs) in water using the natural polymer gum karaya (GK) as both reducer and stabiliser. The colloids were characterised by UV–Vis, TEM, zeta‑potential and DCS

AbstractNanocrystalline strontium ferrite (SrFe12O19) was synthesized by a sol–gel auto‑combustion route with citric acid as a chelating agent. The precursor pH was varied from 0 to 8 and the powders were calcined at a low temperature of 900 °C. Structural, microstructural and magnetic properties we

AbstractWe synthesized tin niobate photocatalysts with two distinct crystal structures—froodite (SnNb2O6) and pyrochlore (Sn2Nb2O7)—using a simple solvothermal route. By systematically varying the synthesis pH, we tuned particle size, band‑edge potentials, and surface chemistry, and correlated these

AbstractBy integrating polyaniline (PANI) onto nitrogen‑doped ordered mesoporous carbon (NOMC) through an in‑situ polymerization strategy, we achieved a hybrid material that delivers a record specific capacitance of 276.1 F g⁻¹ at 0.2 A g⁻¹ in 6 M KOH. The hybrid also exhibits an energy density of 3

Abstract Amorphous indium‑gallium‑zinc‑oxide (a‑IGZO) has become a key material for next‑generation LCD backplanes, yet its integration into mass‑produced displays is limited by chemical sensitivity during etching. We present a Clean Etch‑Stopper (CL‑ES) process that introduces a ~100 nm SiOx etch‑s

Abstract We report a facile, hydrothermally synthesized thiol‑functionalized silica nanosphere (SiO₂‑SH) platform that is subsequently decorated with SnO₂ quantum dots (QDs). The resulting SnO₂/SiO₂ composite nanospheres (NSs) display strong, visible‑light–responsive fluorescence, enabling real‑time

Abstract Polystyrene (PS) nanoparticles doped with diphenyloxazole (PPO) and capped with a cross‑linked poly‑N‑isopropylacrylamide (PNIPAM) shell form PS‑PPO‑PNIPAM hybrid nanosystems (NS). Fluorescence studies of chlorin e₆ added to these NS demonstrate efficient electronic excitation energy transf

AbstractWe proposed and demonstrated MgZnO metal-semiconductor-metal (MSM) ultraviolet photodetectors (UV) assisted with surface plasmons (SPs) prepared by the radio frequency magnetron sputtering deposition method. After the decoration of their surface with Pt nanoparticles (NPs), the responsivity

Abstract We have derived a comprehensive model for the dielectrophoretic (DEP) force exerted on micro‑ and nanoscopic particles when exposed to frequency‑modulated (FM) electric fields. By tuning the FM wave’s frequency band to encompass the crossover frequency fX of the real part of the Clausius–Mo

AbstractCdSSe nanobelts (NBs) are synthesized by thermal evaporation and then characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), photoluminescence (

AbstractWe examined how the thermal stability of alumina support layers, fabricated by radio‑frequency sputtering under different atmospheres, influences the growth of vertically aligned single‑walled carbon nanotube (VA‑SWCNT) arrays. Reactive sputtering with an O₂–Ar mixture produced a Si‑rich al

AbstractWe report a streamlined, one‑pot approach to encapsulate silver nanoparticles (Ag NPs) within hierarchical porous silicalite‑1 (HPS‑1), yielding a catalyst with an exceptionally high surface area (243 m2 · g−1) and dual pore sizes (1.75 nm and 3.96 nm).

The obtained CQDs are with an average size of 3.1 nm. They reveal uniform morphology and well-crystalline and can generate bright blue-gree

AbstractWe demonstrate that a half‑metallic Heusler alloy, Co₂FeAl, deposited on a Pb(Mg₁/₃Nb₂/₃)O₃–PbTiO₃ (PMN‑PT) piezoelectric substrate, exhibits non‑volatile, electric‑field‑induced changes in its magnetic properties at room temperature. By applying pulsed electric fields along the [100] and [0

AbstractBackgroundCryptococcus neoformans is an encapsulated yeast. There is still little quick and effective solution for the diagnosis or treatment of C. neoformans infection at an early stage in clinical. Antibody-conjugated silica-modified gold nanorods (GNR-SiO2-Ab) can conjugate C. neoformans

AbstractA facile hydrothermal approach has been developed to produce ultralong, thin copper nanowires (CuNWs) with an average diameter of 35 nm and a length of 100 µm. The synthesis uses inexpensive, non‑toxic precursors: copper(II) chloride dihydrate (CuCl2·2H2O), octadecylamine (ODA) as capping ag
