AbstractGraphene (G) and graphene oxide (GO) nanoparticles are emerging as promising modifiers for orthopedic implant surfaces, yet their safety and antimicrobial profiles remain incompletely defined. We evaluated in‑vitro cytotoxicity on bone marrow mesenchymal stem cells (BMSCs) and in‑vivo biocom
AbstractGold nanoprobes are emerging as transformative tools for disease diagnostics in computed tomography (CT). Compared to small‑molecule iodine agents, nanoparticles offer superior in‑vivo detection due to their larger surface area and tunable physicochemical properties. Here we report the syn
AbstractIn2O3 nanoparticles hybrid twins hexagonal disk (THD) ZnO with different ratios were fabricated by a hydrothermal method. The as-obtained ZnO/In2O3 composites are constituted by hexagonal disks ZnO with diameters of about 1 μm and In2O3 nanoparticles with sizes of about 20–50 nm. With the in
AbstractWe investigated how water, in its various physical states, influences the structure and dielectric properties of microcrystalline cellulose (MCC) using X‑ray diffraction, thermogravimetric analysis, and dielectric spectroscopy. The study shows that water molecules reside in the macropores of
AbstractAl-doped ZnO (AZO) thin films were deposited directly on p-GaN substrates by using a two-step deposition consisting of polymer assisted deposition (PAD) and atomic layer deposition (ALD) methods. Ohmic contacts of the AZO on p-GaN have been formed. The lowest sheet resistance of the two-step
AbstractBuilding on bubble electrospinning (BE), we developed a modified free‑surface electrospinning (MFSE) system that integrates a cone‑shaped air nozzle with a copper‑tube reservoir, significantly boosting the yield of high‑quality nanofibers. The MFSE process incorporates sodium dodecyl benzene
Abstract We report on the alignment of carbon nanoparticles—graphite nanoplatelets (GNPs) and multi‑wall carbon nanotubes (MWCNTs)—in a low‑viscosity epoxy matrix using an alternating current (AC) electric field. Optical microscopy, electrical measurements, and analytical modeling were combined to a
AbstractWe theoretically investigate highly tensile-strained Ge nanowires laterally on GaSb. Finite element method has been used to simulate the residual elastic strain in the Ge nanowire. The total energy increment including strain energy, surface energy, and edge energy before and after Ge deposit
AbstractThe common definition of the spatially dispersive permittivity is revised. The response of the degenerate electron gas on an electric field satisfying the vector Helmholtz equation is found with a solution to the Boltzmann equation. The calculated longitudinal dielectric function coincides w
AbstractWe report a highly sensitive electrochemical DNA biosensor for detecting Vibrio cholerae DNA. The sensor uses polystyrene‑co‑acrylic acid (PSA) latex nanospheres loaded with gold nanoparticles (AuNPs) as a DNA carrier matrix. Differential pulse voltammetry (DPV) with an anthraquinone‑based o
AbstractElectron paramagnetic resonance (EPR) was employed to investigate the paramagnetic evolution of fullerene soot (FS), fullerene black (FB), and their composites with Phenylon C-2 (PhC‑2). For the first time, a pronounced amplification of EPR signals was recorded in FB, FS, and composite sampl
AbstractWe present a cost‑effective, in‑situ polymerization route to produce a multi‑hierarchical porous polyaniline (PANI) composite on a commercial polyurethane sponge. The sponge scaffold offers a vast inter‑connected surface that facilitates the growth of PANI nanobranches, yielding a flexible,
AbstractAl2O3:SiOC nanocomposites were prepared by thermally treating fumed alumina nanoparticles grafted with phenyltrimethoxysilane (PhTMS). We examined how annealing temperature in an inert atmosphere influences the material’s structure and photoluminescence (PL) using FTIR and PL spectroscopy u
Abstract Titanium dioxide nanoparticles (TiO₂‑NPs) are ubiquitous in food, cosmetics, and medical products, yet their safety profile remains uncertain. Using ICR mice, we examined the biodistribution, organ‑specific toxicity, and underlying mechanisms of TiO₂‑NPs delivered via intraperitoneal (i.p.)
AbstractThis study investigates how hydrothermal temperature (150–240 °C) controls the crystallization of molybdenum disulfide (MoS2) nanoflakes on graphene nanosheets. Flower‑shaped MoS2 nanoflakes are successfully anchored onto graphene, and their morphology, crystal phase, and electrochemical per
AbstractSilver nanowires (Ag NWs) have emerged as the frontrunner for next‑generation flexible transparent electrodes, poised to replace brittle indium tin oxide (ITO). We report a scalable, polyvinylpyrrolidone (PVP)‑mediated polyol synthesis that yields Ag NWs with aspect ratios (AR) ranging from
Abstract We present a simple, scalable route to produce yolk‑shell Cu@C nanocomposites in which copper cores (30–55 nm) are encapsulated inside hollow carbon spheres (≈210 nm diameter, 80 nm cavity). During pyrolysis, the confined cavity confines Cu nucleation, yielding monodisperse cores whose siz

By optimizing deposition parameters, we achieved ultrathin, h
