Abstract Electrical transport in single‑nanostructures dictates the performance of next‑generation nanodevices. NiCo₂O₄ nanowires, widely used as electrodes in electrocatalysis, supercapacitors, and lithium‑ion batteries, have yet to have their intrinsic conduction mechanisms fully clarified. Here

AbstractElectrochemical sensors have the high sensitivity, fast response, and simple operation for applications in biological, medical, and chemical detection, but limited by the poor stability and high cost of the electrode materials. In this work, we used PtNi lagged-like nanowire for caffeic acid

Abstract We report a systematic investigation of random telegraph noise (RTN) observed in the read current of a FinFET‑based dielectric RRAM (FIND RRAM) cell. After repeated cycling stress, the RTN amplitude and frequency increase markedly, compromising data integrity. Our measurements show that hig

AbstractNanoparticle toxicity research has intensified as these materials become ubiquitous in everyday products. Certain nanoparticles can stimulate mucus secretion, potentially harming airway integrity. Lanthanum strontium manganite (LSM) is a perovskite nanoparticle extensively used in solid‑oxid

Abstract We demonstrate that amorphous silicon (a‑Si) passivation, deposited by magnetron sputtering at room temperature, yields germanium (Ge) p‑MOSFETs with record‑high effective hole mobility on (001)‑oriented substrates. With a 0.9‑nm a‑Si cap, the (001) devices deliver a peak μeff of 278 cm²/V·

AbstractSnSe2 field-effect transistor was fabricated based on exfoliated few-layered SnSe2 flake, and its electrical and photoelectric properties have been investigated in detail. With the help of a drop of de-ionized (DI) water, the SnSe2 FET can achieve an on/off ratio as high as ~ 104 within 1 V

AbstractCdS/CdSe quantum dot‑sensitized solar cells (QDSSCs) were fabricated on two distinct TiO2 photoanodes: highly (001)-oriented nanosheets (NSs) and commercial Degussa P‑25 nanoparticles. The NSs were produced via a hydrothermal route, yielding sheets with a 70 % exposure of the active (001) fa

AbstractWe present a unified one‑pot route that yields high‑quality binary and ternary metal sulfide nanocrystals (NCs), including PbS, Cu2S, ZnS, CdS, Ag2S, CuInS2, and Cu‑doped CdS. The method relies solely on inorganic metal salts and n-dodecanethiol (DDT), eliminating the need for pre‑formed org

AbstractWe report the fabrication of electrodeposited n‑type ZnO nanorods combined with p‑type Cu2O, CuSCN, and NiO nanostructures for the efficient photodegradation of methyl orange (MO). This study is the first to systematically examine how the choice of semiconductor, the formation of heterojunct

AbstractEnzyme‑linked immunosorbent assay (ELISA) remains a gold standard for disease screening, yet its sensitivity hinges on how well antigens are immobilized on the polystyrene (PS) plate. We developed a simple, reproducible surface chemistry using 3‑(aminopropyl) triethoxysilane (APTES) followe
