AbstractThe effect of fluid media on material removal and subsurface defects evolution in nano-cutting process of single-crystal copper is investigated by means of molecular dynamics simulation. In this paper, the removal mechanism of the chip and formation mechanism of machined surface are investig

AbstractWe monitored the corrosion of individual monocrystalline silver triangles for over 24 h under ambient laboratory conditions using atomic force microscopy (AFM) and micro‑spectroscopy. The particles, chosen for their well‑defined crystallographic orientation when deposited on a substrate, exh

AbstractOptical bioimaging with exogenous luminophores emitting in short-wave infrared spectral region (SWIR, ~ 1000–1700 nm) is a rapidly developing field, and the development of multiple SWIR-photoluminescent nanoprobes has recently been reported. In this regard, hyperspectral imaging (HSI), combi

AbstractThis work reports on the microstructure-controlled formation of interconnected carbon-layered Al2O3 ceramics using carbon nanoparticles (CNP)-alumina (Al2O3) composite particles. The Al2O3 micro-particles used in this study were obtained by granulation of nano-sized Al2O3 nanoparticles with

AbstractPlasmon-induced transparency is an efficient way to mimic electromagnetically induced transparency, which can eliminate the opaque effect of medium to the propagating electromagnetic wave. We proposed an aperture-side-coupled asymmetric bowtie structure to realize on-chip plasmon-induced tra

AbstractStretchable smart electronics are rapidly advancing the fields of human‑motion energy harvesting and self‑powered biomechanical monitoring. Here we report a novel, fully rubber‑based thread‑shaped triboelectric nanogenerator (TENG) that combines silver‑coated glass microspheres with silicone

AbstractIn this work, we present a magnetic graphene field‑effect transistor (MGFET) biosensor fabricated by transferring a chemical‑vapor‑deposition (CVD) graphene film onto a glass substrate to form the conductive channel and sensing layer. The graphene surface is functionalized with 1‑pyrenebutan

AbstractOxygen reduction reaction (ORR) underpins the operation of fuel cells and metal‑air batteries. While platinum‑based catalysts deliver high activity, their cost, limited durability, and methanol sensitivity impede commercialization. Here we report a simple, scalable synthesis of nitrogen‑do

Abstract1 µm length. Casting these SNs produces optically transparent membranes (≥75 % light transmission) that are mechanically robust (≈4.5 GPa Young’s modulus) and exhibit enhanced hydrophilicity. By tuning the pH, the negatively charged SNs aggregate and can be re‑dispersed, allowing concentrati

AbstractPolytetrafluoroethylene (PTFE) is a fascinating electret material widely used for energy harvesting and sensing, and an enhancement in the performance could be expected by reducing its size into nanoscale because of a higher surface charge density attained. Hence, the present study demonstra

AbstractThe characteristics of a circularly polarized anomalous vortex beam (CPAVB), focused by an objective lens with a high numerical aperture (NA), are studied analytically and theoretically. It shows that the topological charge can affect the beam profile significantly and a flat-topped (FT) bea

AbstractWe demonstrate that the contact geometry of single‑molecule junctions can be tuned by the position of a methoxy side‑group on carboxylic‑acid ligands. Using electrochemical jump‑to‑contact scanning‑tunneling‑microscopy break‑junction (ECSTM‑BJ) on Cu electrodes, 2‑methoxy‑1,3‑benzenedicarbox

AbstractHfO₂‑based ferroelectric field‑effect transistors (FeFETs) with a metal/ferroelectric/insulator/semiconductor (MFIS) gate stack are emerging as strong candidates for high‑density, high‑speed non‑volatile memories. Although their retention performance meets industrial demands, the memory win

Abstract Quasi‑two‑dimensional (2D) perovskites are emerging as high‑performance luminophores thanks to their large exciton binding energies and exceptional photoluminescence efficiencies. In practice, however, these materials often contain a mix of phases, and the presence of excessive low‑dimensio

Abstract Well‑defined polymer micelles with a core–shell architecture serve as an effective platform for stabilizing silver nanoparticles (AgNPs) and delivering antimicrobial agents. This study presents a rational, green, and scalable synthesis of AgNP‑decorated copolymer micelles based on poly(2‑di
