Abstract We examined the long‑term effect of atmospheric humidity on self‑assembled CH3NH3PbI3 (MAPbI3) microwires (MWs) using photoluminescence (PL), Raman spectroscopy, and X‑ray diffraction (XRD). Over 11 weeks, the MWs displayed a 21 nm red‑shift of the PL peak (from 759 nm to ~780 nm) and an ov

Abstract We report the fabrication of Ti0.91O2 nanosheet/CdS quantum‑dot hybrid spheres by a layer‑by‑layer self‑assembly route. Photoluminescence (PL) measurements reveal a pronounced spectral shift and a markedly prolonged PL lifetime of 3.75 ns, compared with 0.43 ns for Ti0.91O2 alone and 0.35 n

AbstractNew representative of carbacylamidophosphates - diphenyl-N-(trichloroacetyl)-amidophosphate (HL), which contains two phenoxy substituents near the phosphoryl group, was synthesized, identified by elemental analysis and IR and NMR spectroscopy, and tested as a cytotoxic agent itself and in co

AbstractDirect methanol fuel cells (DMFCs) suffer from high methanol crossover and the expensive Nafion® membrane. We fabricated a non‑Nafion, sodium alginate (SA) based polymer electrolyte membrane reinforced with 0.02–0.20 wt % sulfonated graphene oxide (SGO) via a simple solution‑casting approach

Abstract We demonstrate a 4 × 4 flexible sensor array comprising 16 micro‑capacitive units fabricated from a 50 µm thick poly(vinylidene fluoride) (PVDF) piezoelectric film. Optical imaging and piezoresponse force microscopy (PFM) confirm a sharp PVDF/electrode interface and robust piezoelectric dom

AbstractWe study the spin- and valley-dependent energy band and transport property of silicene under a periodic potential, where both spin and valley degeneracies are lifted. It is found that the Dirac point, miniband, band gap, anisotropic velocity, and conductance strongly depend on the spin and v

AbstractIn this study, reduced graphene oxide (rGO) and carbon nanotubes (CNT) were incorporated into CL‑20 composites as conductive fillers to boost thermal conductivity. Scanning electron microscopy (SEM) and X‑ray diffraction (XRD) revealed a uniform, three‑dimensional heat‑conducting network whe

Abstract We have engineered a thermoplastic polyurethane (TPU) nanofibrous composite, functionalized in situ with polyaniline (PANI) via electrospinning, to create a flexible strain sensor that can endure strains up to 165% with rapid response and long‑term stability. The composite maintains consist

AbstractSilicon nanowire (NW) field-effect transistor (FET) sensors of various lengths were fabricated. Transport properties of Si NW FET sensors were investigated involving noise spectroscopy and current–voltage (I–V) characterization. The static I–V dependencies demonstrate the high quality of fab

AbstractA convenient, low-cost, and highly sensitive fluorescent aptasensor for detection of leukemia has been developed based on graphene oxide-aptamer complex (GO-apt). Graphene oxide (GO) can absorb carboxyfluorescein-labeled Sgc8 aptamer (FAM-apt) by π-π stacking and quench the fluorescence thro

AbstractWound healing is a multifaceted process governed by growth factors, cellular migration, and extracellular matrix remodeling. While bioactive dressings have advanced, only a handful reach clinical practice due to delivery challenges. We engineered a nanofibrous scaffold composed of chitosan (

Abstract This study presents a straightforward, low‑cost method for decorating anodic TiO₂ nanotube (NT) arrays with cerium oxide (CeO₂) nanoparticles (NPs). By exploiting the TiO₂ NTs as nano‑containers, a dilute Ce(NO₃)₃ solution is introduced into the tubes, followed by a 450 °C anneal that therm
