Abstract Poplar wood’s intricate cellular architecture offers a cost‑effective, renewable scaffold for nanoparticle synthesis. In this study, we successfully reduced copper(II) chloride within poplar wood, producing copper nanoparticles that are uniformly sized, face‑centered cubic, and highly stabl

AbstractSingle‑phase CoMoO4 was produced by a facile hydrothermal method followed by calcination at 400 °C. Morphological, structural, and electrochemical characteristics of samples synthesized for 1, 4, 8, 12, and 24 h were systematically investigated. All samples exhibit a microsphere morphology

AbstractOne key issue for the development of molecular electronic devices is to understand the electron transport of single-molecule junctions. In this work, we explore the electron transport of iodine-terminated alkane single molecular junctions using the scanning tunneling microscope-based break j

AbstractThis study presents a nearly droop‑free AlGaN deep‑UV LED emitting at 270 nm. The key innovation is a specially engineered superlattice p‑type electron blocking layer (p‑EBL) that delivers a high hole concentration, enhancing hole injection into the multiple quantum wells (MQWs). The increas

AbstractReactive oxygen species (ROS) are pivotal in cell signaling, yet their overproduction drives oxidative damage. Precise, live‑cell quantification of ROS is therefore essential for both basic biology and clinical diagnostics. Traditional fluorogenic probes paired with horseradish peroxidase (H

AbstractThis study demonstrates a fully green synthesis of gold (AuNPs) and silver nanoparticles (AgNPs) using a platycodin‑D (PD)‑enriched fraction derived from the medicinal herb Platycodi Radix (Platycodon grandiflorum). The PD‑enriched extract acts as a natural reducing and stabilizing agent, en

AbstractSp²‑bonded two‑dimensional materials such as graphene and hexagonal boron nitride (h‑BN) are celebrated for their exceptional thermal conductivities. We report micro‑Raman measurements of the in‑plane E₂g optical phonon peaks—≈1580 cm⁻¹ in graphene and ≈1362 cm⁻¹ in h‑BN—across a wide temper

AbstractObjectiveWe investigated whether CO₂ fractional laser can increase the skin penetration of ethosomes encapsulating 5‑fluorouracil (5‑FU) and assessed the therapeutic efficacy of this combination in a rabbit ear hypertrophic scar model.MethodsPermeation and retention of 5‑FU were quantified b

Abstract4‑Nitrophenol (4‑NP) is a priority pollutant that poses significant carcinogenic and genotoxic risks to humans and wildlife even at trace levels. Herein, we report a novel molecularly imprinted core–shell nanohybrid that functions as a ratiometric fluorescent sensor for highly sensitive and

Abstract A highly efficient ternary photocatalyst was engineered by integrating silver orthophosphate (Ag3PO4), attapulgite (ATP), and TiO2. The resulting heterojunction promotes effective separation of photogenerated electrons and holes, markedly boosting photocatalytic performance. Structural anal

AbstractThis study establishes how the two‑dimensional to three‑dimensional (2D‑3D) critical transition thickness in GeSiSn films depends on Sn composition when the Ge fraction is fixed. Growth at 150 °C and Sn contents up to 16 % reveal that the transition thickness shrinks as Sn rises, confirming

Here we report a robust fabrication route that incorporates water‑soluble CdSe/ZnS quantum dots (QDs) stabilized with a tri‑functional polyethylene glycol (PEG) ligand into polyelec

AbstractWe report a cost‑effective, noble‑metal‑free photocatalyst comprising 7‑nm Cd0.5Zn0.5S quantum dots (QDs) uniformly anchored on 15–30‑nm Ni2P porous nanosheets. The high‑surface‑area Ni2P framework facilitates efficient charge separation and provides abundant active sites for the hydrogen e

AbstractWe engineered a multifunctional micellar system that simultaneously targets CD44 receptors on tumor cells and the mitochondria within those cells. The carrier, designated TPP‑oHA‑S‑S‑Cur, is assembled from (5‑carboxypentyl)triphenylphosphonium bromide (TPP), oligomeric hyaluronic acid (oHA),

AbstractCombining a platinum–nickel (PtNi) alloy cocatalyst with a g‑C3N4/graphene oxide (GO) hybrid, sensitized by the organic dye Eosin Y, delivers an unprecedented hydrogen evolution rate of 5.89 mmol g−1 h−1 under visible‑light irradiation. The PtNi alloy, synthesized by a straightforward chemic

AbstractIn this paper, we investigate the friction behaviors of graphene flakes sliding on a gold substrate using molecular dynamics simulations. The effects of flake size, flake shape, relative rotation angle between flake and substrate, and crystal orientation of substrate on the friction process

AbstractThe categorization of microbial strains is conventionally based on the molecular method, and seldom are the morphological characteristics in the bacterial strains studied. In this research, we revealed the macromolecular structures of the bacterial surface via AFM mechanical mapping, whose r
