AbstractA graphene-loaded metamaterial absorber is investigated in the mid-infrared region. The light-graphene interaction is greatly enhanced by virtue of the coupled resonance through a cross-shaped slot. The absorption peaks show a significant blueshift with increasing Fermi level, enabling a wid

A self-biased MOS voltage divider is proposed to provide bias current for whole voltage reference, which is a positive temperature coefficient (TC) current conta

By engineering two opposing transmission‑phase gradients along the x‑direction

Abstract Alzheimer’s disease (AD) remains one of the most costly neurodegenerative disorders worldwide, underscoring the urgency for non‑invasive, early‑diagnostic tools. Emerging evidence links abnormal cholesterol accumulation around senile plaques to AD pathogenesis, suggesting cholesterol as a v

AbstractModulated continuous‑wave (CW) lasers trigger a photothermal response that rapidly absorbs light and generates thermal waves around irradiated nanostructures. In this study, we explore how such laser irradiation influences particle fragmentation and consequently improves the thermal diffusi

The RGUC FET represents nearly ideal subthreshold characteristics till the distance between source/drain (S/D) contacts reduced to 2

AbstractThe geometric phase is an extra phase evolution in the wave function of vibrations that is potentially applicable in a broad range of science and technology. The characteristics of the geometric phase in the squeezed state for a carbon-nanotube-based nanowire resonator have been investigated

The structure consists of a perforated silver film, an aluminum‑oxide spacer, and a continuous silver ground plane. The hybrid FP/VP resonance delivers

AbstractHemin, a highly bioavailable iron source, is limited by its negligible aqueous solubility. We report a simple dialysis‑based approach that yields two distinct hemin nanoparticle morphologies—tadpole‑shaped (≈200 nm head, 100 nm tail) and sphere‑shaped (50–100 nm). Both forms exhibit dramatic
