AbstractIn Au/WO3/Au devices, a pronounced negative photoconductivity (NPC) emerges in humid environments, attributable to the surface accumulation of H+ ions. When illuminated with 445‑nm violet light, photogenerated holes oxidise adsorbed H2O, producing H+ and O2. The photo‑excited electrons lack
Abstract Using density‑functional theory coupled with non‑equilibrium Green’s functions, we investigated how adsorption of transition‑metal (TM) atoms V, Cr, and Mn at the edges of armchair black phosphorene nanoribbons (APNRs) reshapes their electronic, magnetic, and transport characteristics. The
AbstractWO3 integrated with graphene (GR) has emerged as a highly effective photocatalyst for diverse applications. Yet, the exact pathways of charge carrier transfer during photocatalysis remain elusive due to the complex interfacial interactions. In this study, we fabricated WO3/GR layered films a
AbstractWe report a magnetically recoverable ternary nanocomposite (ZnO/Fe3O4/g‑C3N4) that demonstrates superior photocatalytic performance for the visible‑light degradation of monoazo dyes. Structural and optical properties were characterized by XRD, TEM, EDS, XPS, PL, UV‑vis DRS, and photo‑electro
AbstractHybrid nanostructures with intricate morphologies and high photocatalytic activity are notoriously difficult to fabricate, often requiring specialised skills and costly processes. Here we report a stepwise synthesis of flower‑shaped Au@CdS‑CdS nanoflowers that combine a gold core, a cadmium
AbstractIn this study, we investigate AlGaN‑based deep ultraviolet (DUV) light‑emitting diodes (LEDs) fabricated with a flip‑chip architecture and a variety of meshed p‑type contact geometries. Using three‑dimensional finite‑difference time‑domain (3D‑FDTD) simulations, we demonstrate that both tran
AbstractSize‑dependent surface phenomena—catalysis, quantum‑dot photoluminescence, and plasmonic resonances—are governed by the coordination chemistry of metal and semiconductor nanoclusters. In this work we quantify these dependencies using concise “magic formulas” that relate the number of structu
AbstractZnO porous nanosheets (PNSs) were partially functionalised by anchoring amorphous BiVO4 onto zinc carbonate nanosheets followed by calcination at 500 °C. This treatment converts the surface into a Bi3.9Zn0.4V1.7O10.5 (BZVO) phase when the BiVO4 loading is low. Photocurrent and photoluminesce
Abstract90 % of its brightness after 300 h of continuous operation, setting a new benchmark for inorganic perovskite LEDs. IntroductionWhite light‑emitting diodes (WLEDs) are the future of solid‑state lighting, offering superior energy efficiency, long lifetime, and high luminous efficacy. Quantum‑d
AbstractMicrochannel plates (MCPs) are critical in high‑gain electron multipliers used across photon and particle detection. Traditional MCPs suffer from high dark current, limited lifetime, and sub‑optimal secondary‑electron‑emission (SEE) performance. In this study, we deposit a conformal Al₂O₃ SE
AbstractThe NiO/NiCo2O4 mixtures with unique yolk-shell structure were synthesized by a simple hydrothermal route and subsequent thermal treatment. The elemental distribution, composition, and microstructure of the samples were characterized by transmission electron microscopy (TEM), X-ray diffracti
AbstractFor the semicircular plasmonic lens, the spiral phase is the origin of the spin-dependent surface plasmon polariton (SPP) focusing. By counterbalancing the spin-dependent spiral phase with another spiral phase or Pancharatnam-Berry phase, we realized the SPP focusing independent from the spi
AbstractWe examined the biodegradation of poly(lactic acid) (PLA) incorporated with functionalized anatase TiO₂ (g‑TiO₂) over 90 days in a laboratory‑scaled composting system that satisfies GB/T 19277/ISO 14855. Surface morphology, crystallinity, thermal transitions, molecular‑weight evolution, and
Abstract Background We engineered a drug‑eluting gastrointestinal (GI) stent that releases piperlongumine (PL) via reactive oxygen species (ROS)‑sensitive nanofiber mats. The PL‑laden mats were designed to provide a localized, ROS‑triggered anticancer effect against cholangiocarcinoma (CCA) cells. M
AbstractThe two‑dimensional semiconductor MoS₂ has emerged as a promising material for ultrafast photonics due to its broadband saturable absorption and high third‑order nonlinearity. In this study, we fabricate a novel MoS₂‑doped sol‑gel glass, forming a MoS₂/SiO₂ composite. The composite exhibit
Abstract92 % efficiency over ten consecutive runs, confirming excellent stability. IntroductionThe rapid expansion of industry has released a spectrum of toxic pollutants—organic and inorganic—that threaten ecosystems and human health. Efficient, clean degradation technologies are therefore critical
AbstractTraditional chemotherapy often fails due to severe side effects and the rapid emergence of multidrug resistance. We investigated C60 fullerene as a nanoscale carrier for doxorubicin (Dox) to enhance drug delivery specifically to leukemic cells. Non‑covalent C60‑Dox complexes (1:1 and 2:1 rat
AbstractBy reacting PbC2O4 and TiO2 in eutectic NaCl‑KCl, we successfully prepared both spherical and rod‑like PbTiO3 (PTO) powders using molten salt synthesis (MSS) and template MSS, respectively. X‑ray diffraction confirms a pure tetragonal phase for all samples. Varying the molar ratio of PbC2O4:
AbstractWe report surfactant‑free, low‑Au‑loading Cu₂O@Au and Au hollow cubes fabricated by galvanic replacement of electrodeposited Cu₂O cubes. The Cu₂O@Au composite delivers a Faradaic efficiency (FE) of 30.1 % for CO at –1.0 V vs. RHE—approximately twice the FE obtained with either Cu₂O or Au al
AbstractMultiple‑band metamaterial absorbers (MPAs) have attracted extensive research due to their near‑perfect absorption, sub‑wavelength thickness, and customizable response. However, conventional designs exhibit widely spaced resonance peaks, resulting in significant off‑resonance loss and missed
