AbstractWe report the hydrothermal synthesis and photo‑reduction of Ag/BiPbO2Cl nanosheet composites. TEM, XRD, and UV‑Vis diffuse‑reflection spectroscopy confirm the morphology, crystal structure, and optical response of the materials. A 0.5 wt % Ag loading yields photocatalytic activity 3.6 times

AbstractPerovskite solar cells (PSCs) fabricated in ambient air typically suffer from low power conversion efficiencies (PCEs) due to moisture‑induced defects in PbI₂ precursor films. In this study, we systematically examined how humidity affects PbI₂ crystallization and the subsequent conversion to

AbstractWe introduce a planar four‑strip metallic metamaterial that exhibits an ultra‑sharp Fano resonance in the terahertz band. At 0.81 THz, the structure delivers a 25 % transmission dip with a bandwidth of 0.014 THz, corresponding to a Q‑factor of 58. The asymmetric line shape results from the c

AbstractBy coupling titanium dioxide (TiO₂) nanotube arrays with the narrow‑gap semiconductor bismuth selenide (Bi₂Se₃), we achieved a substantial improvement in photocathodic protection for 304 stainless steel under visible light. The Bi₂Se₃/TiO₂ nanocomposites were fabricated via a two‑step, scala

AbstractWe present a rapid, user‑friendly lateral flow strip assay (LFSA) that employs two highly specific aptamers—A09 and B09—functionalized with gold nanoparticles (AuNPs) to detect rongalite, a hazardous reagent occasionally used as a food additive. The biotin‑labeled A09 aptamer is immobilized

AbstractA new type of dipole plasmon excitations in colloidal highly doped ZnO nanocrystals has been studied by means of many-body quantum mechanical approach. We demonstrate that in photodoped ZnO nanocrystals, the conduction band electrons are localized close to the surface and the plasmon oscilla

AbstractGold nanoshells exhibit pronounced light scattering and absorption near their plasmonic resonance, enabling biomedical imaging and photothermal therapy. At the nanoscale, the dielectric response of gold is altered by surface scattering of conduction electrons, which becomes significant when

Abstract GaTe and C2N monolayers, recently synthesized, exhibit intriguing electronic and optical characteristics. Here we employ first‑principles density functional theory to investigate the structural, electronic, and optical behavior of a GaTe/C2N van der Waals (vdW) heterostructure. The heterost
