AbstractThe rise of antibiotic‑resistant bacteria and the persistence of drug residues in food chains pose a global public‑health crisis. Conventional antibiotics are increasingly ineffective, demanding rapid development of novel antimicrobials. Copper oxide (CuO) nanoparticles (NPs) offer a versati

AbstractWe present a finite‑difference time‑domain (FDTD) investigation of vertically aligned GaAs nanowire (NW) arrays functionalized with Au nanoparticles (NPs). The NWs, 1 µm long with 100 nm diameter and 165–500 nm periodicity, are decorated with 30–60 nm Au NPs on their sidewalls. Our simulatio

AbstractIn photonics, it is essential to achieve high-quality (Q)-factor resonances to improve optical devices’ performances. Herein, we demonstrate that high-Q-factor dual-band Fano resonances can be achieved by using a planar nanohole slab (PNS) based on the excitation of dual bound states in the

AbstractSecondary electron emission (SEE) is the cornerstone of electron‑multiplier performance. The SEE coefficient depends strongly on the emission‑layer material and its thickness. Thin layers yield insufficient SEE, while excessively thick layers prevent timely charge replenishment by the cond

AbstractMicro‑LED displays promise unprecedented contrast, brightness, and color fidelity, yet their intrinsic Lambertian emission limits viewing angles. This study introduces a primary optical design that deposits a highly reflective thin‑film coating (HRTF) on the light‑emitting surface of micro‑L

AbstractWe report results of comprehensive experimental exploration (X-ray photoemission, Raman and optical spectroscopy) of carbon nanofibers (CNFs) in combination with first-principles modeling. Core-level spectra demonstrate prevalence of sp2 hybridization of carbon atoms in CNF with a trace amou

AbstractBlack phosphorus nanoparticles (BPs) at bio‑safe concentrations activate transglutaminase 2 (TG2) and upregulate extracellular matrix (ECM) components, thereby accelerating osteogenic differentiation of ectodermal mesenchymal stem cells (EMSCs). BPs exhibit excellent biocompatibility and bio

AbstractIcariin (ICA), a flavonol glycoside from Epimedium, exhibits cardioprotective, antioxidant, and anti‑inflammatory properties but suffers from poor water solubility, rapid clearance, and low oral bioavailability. We synthesized a hydrophilic polyethylene glycol monomethyl ether (mPEG) conjug

AbstractTraditional agriculture relies heavily on large quantities of synthetic agrochemicals, which can compromise soil health, water quality, and biodiversity. Smart nanomaterials—engineered at the nanoscale to deliver active ingredients (AIs) in a controlled, targeted manner—offer a sustainable

AbstractWe demonstrate terahertz dielectric metasurfaces with anisotropic multipoles within the framework of the generalized Huygens principle, in which the interference among these multipoles achieves giant phase shift with broadened bandwidth and high transmission coefficients. More importantly, o

AbstractWe present a phase‑gradient metasurface composed of discontinuous regular hexagonal silicon nanorods on a silica substrate that delivers exceptional anomalous transmission in the near‑infrared (1400–1600 nm). Numerical FDTD simulations show a total transmission of 96.5 % and a desired anomal

Abstract Surface traps profoundly influence the performance of AlGaN/GaN HEMTs. By simulating 2DEG electron concentration across a wide range of aluminum fractions (5–50 %) and surface donor trap parameters (concentration 10¹¹–10¹⁶ cm⁻², energy 0.2–1.4 eV), we demonstrate that 2DEG density saturates

AbstractDue to the wide use of iron in all kinds of areas, the design and construction of direct, fast, and highly sensitive sensor for Fe3+ are highly desirable and important. In the present work, a kind of fluorescent MXene quantum dots (MQDs) was synthesized via an intermittent ultrasound process

AbstractWe report three GaN‑based multiple quantum well (MQW) samples grown at a low temperature of 750 °C. Instead of the conventional temperature ramp‑up, we introduced a hydrogen/ammonia (H₂/NH₃) gas mixture during the interruption after depositing the InGaN well layers. By varying the hydrogen f

Abstract Mixed‑metal oxide nanoparticles are of high scientific and technological interest due to their versatile applications. However, controlling size and composition remains a major challenge. In this work, we synthesized Co‑doped FeMn2O4 nanoparticles by a solvothermal route at 190 °C for 24 h

AbstractWe report a dual‑function nanocomposite, AgZnO/polyoxometalates (AgZnO/POMs), synthesized via a sonochemical route that couples AgZnO hybrid nanoparticles with Cu‑based polyoxometalates. Transmission electron microscopy (TEM) confirms a uniform, narrowly distributed particle size (~19.5 nm)

Abstract Advances in nano‑fabrication have driven semiconductor devices to ever smaller dimensions, intensifying sidewall defects that undermine performance. Conventional plasma‑enhanced chemical vapor deposition (PECVD) struggles to deliver the conformality required at the nanometer scale. Atomic

AbstractMicroRNA‑342‑5p (miR‑342‑5p) has been implicated in atherosclerosis (AS), yet its mechanistic role remains unclear. In this study, we investigated how miR‑342‑5p regulates the Wnt3a signalling pathway and influences plaque vulnerability and neovascularisation in an ApoE‑/‑ mouse model of AS.

AbstractOver the past two decades, nanotechnology has propelled the emergence of diverse fluorescent nanomaterials (FNMs) with unique optical properties, enabling breakthroughs in bioimaging and fluorescence‑based detection. Despite their promise, challenges such as limited photoluminescence efficie
