AbstractStrain-engineered self-assembled GeSn/GeSiSn quantum dots in Ge matrix have been numerically investigated aiming to study their potentiality towards direct bandgap emission in the mid-IR range. The use of GeSiSn alloy as surrounding media for GeSn quantum dots (QD) allows adjusting the strai

AbstractMonodispersed magnetic core–shell nanoparticles are pivotal for magnetic fluids, catalysis, and biomedical imaging. Conventional syntheses typically involve multiple steps—solvent exchange, ligand replacement, and repeated centrifugation—slowing down progress toward practical applications. W

AbstractPolystyrene (PS) nanoparticle films arranged in non‑close‑packed arrays were fabricated by ion beam etching (IBE). Systematic studies of etching time, beam current and voltage revealed a remarkably slow etch rate of ~9.2 nm min⁻¹ for 100 nm nanospheres, which varied with prolonged exposure

Abstract Core–shell Fe3O4@C nanoparticles were synthesized via a simple hydrothermal route followed by calcination at 450 °C. The resulting material displays a highly porous structure with a Brunauer–Emmett–Teller (BET) surface area of 238.18 m2 g−1, far exceeding typical Fe3O4 powders. When appli

AbstractRapid‑breakdown anodization (RBA) in perchloric acid yields highly crystalline titania nanotube (TNT) powder. Annealing between 250 °C and 550 °C modifies the nanotube morphology, phase composition and band‑gap energy, while retaining an open‑ended tubular structure only up to 250 °C. The

Abstract We demonstrate a cost‑effective dip‑drop method combined with post‑deposition etching to fabricate a periodic polystyrene nanosphere (PS NS) array on indium‑tin‑oxide (ITO) glass. The monolayer array serves as a photonic crystal window that enhances the light extraction efficiency (LEE) of

AbstractWe demonstrate an electrochemical reduction method to reduce graphene oxide (GO) to electrochemically reduced graphene oxide (ERGO) with the assistance of carbon nanotubes (CNTs). The faster and more efficient reduction of GO can be achieved after proper addition of CNTs into GO during the r

\n \n Abstract\n We report the synthesis of composition‑tunable, cadmium‑free Cu‑doped ZnInS/ZnS core/shell colloidal nanocrystals (CNCs) via a colloidal, non‑injection route. By employing oleate precursors instead of powders, the resulting CNCs exhibit near‑defect‑free photoluminescence. Adj

AbstractWithout nanosafety guidelines, the long-term sustainability of carbon nanotubes (CNTs) for water purifications is questionable. Current risk measurements of CNTs are overshadowed by uncertainties. New risks associated with CNTs are evolving through different waste water purification routes,

Abstract Incorporating nano‑heterostructures into the active layer of bulk heterojunction solar cells can markedly improve device performance. Here we report the in‑situ generation of CdS or Sb₂S₃ nanocrystals within a P3HT:PC₆₁BM blend by adding cadmium or antimony xanthate precursors to the polyme

Abstract Topotactic anion exchange has become a powerful strategy for tailoring the composition and band‑gap energies of cesium lead halide (CsPbX₃) perovskite nanocrystals (NCs). Conventional methods often require harsh reagents or prolonged reaction times. Here, we present a straightforward, envir

AbstractA millstone (MS) was introduced in the production of large-size few-layer-graphene oxide (FLGO) via true shear exfoliation in order to minimize fragmentation. The MS was constructed with two glass plates, where the top plate was designed to rotate against the stationary bottom plate, thereby

This review examines the anodization process, highlighting how anodization parameters and post‑treatment (therm

Abstract We report a flexible fibrous dye‑sensitized solar cell (FFDSSC) that achieves a record 6.35 % photoelectric conversion efficiency. A multilayer TiO₂ photoanode, fabricated by a brush‑coating technique and successive TiCl₄ treatments, suppresses electron recombination and boosts charge captu

Abstract Background Heart rate variability (HRV) is a sensitive marker of autonomic nervous system (ANS) balance and predicts cardiovascular outcomes. Prior work from our laboratory demonstrated that inhalation of multi‑walled carbon nanotubes (MWCNTs) in rats augments both sympathetic and parasympa

AbstractIn recent years, graphene nanomesh (GNM), a material with high flexibility and tunable electronic properties, has attracted considerable attention from researchers due to its wide applications in the fields of nanoscience and nanotechnology. Herein, we have processed large-area, uniform arra

AbstractSensorineural hearing loss remains the most prevalent chronic disability, affecting individuals of all ages. Traditional cochlear implants are bulky, require external power supplies, and limit patient comfort. We introduce a novel bionic cochlear sensor that emulates the basilar membrane’s f

Abstract Employing a double‑sided pyramid grating on crystalline‑silicon (CS) thin films can substantially broaden light‑absorption performance. A front grating effectively suppresses reflection in the short‑wavelength regime, while a rear grating achieves a similar effect at longer wavelengths. Thi

AbstractGermanium offers an attractive theoretical capacity for sodium‑ion batteries, yet its practical use is limited by poor cyclability due to sluggish kinetics and pronounced volume change. We report the first synthesis of high‑purity CuGeO3 (CGO) nanowires via a simple hydrothermal route and e
