Carbon quantum dots synthesis by laser ablation of graphene oxide in biocompatible solutions

A biocompatible dispersion of carbon quantum dots (CQDs) has been obtained by laser irradiation of graphene oxide (GO) in liquid media. The CQD synthesis uses a pulsed IR laser operating at 970 nm, with a 100 ms pulse duration and a fluence of 1.1 kJ/cm2. The carbon target consis...

AVA‐MAPbI 3 Cap‐and‐Root Islands on Mesoporous TiO 2 Toward Neutral‐Color Semi‐Transparent Perovskite Solar Cells in Agrivoltaics

Semi‐transparent perovskite solar cells offer a route to agrivoltaics, combining electricity generation with controlled light transmission for crop cultivation. However, conventional perovskite films preferentially absorb blue photons, producing redshifted transmitted spectra tha...

Screening of sarcopenia in long-term care facilities using wireless surface electromyography and deep transfer learning: a proof-of-concept study

Abstract Background Sarcopenia is prevalent in long-term care facilities (LTCFs) and is associated with falls, functional decline, and mortality. Aims This proof-of-concept study, within the I-COUNT pilot randomized controlled trial, evaluated the feasibility and diagnostic perfo...

Electrical Properties and Interfacial Strain in Thermally Oxidized 4H‐SiC MOS Structures Under Different Post‐Oxidation Annealing

ABSTRACT The electrical behavior of SiO 2 /4H‐SiC interfaces is a central challenge for the development of high‐efficiency MOSFETs, where trap states and interfacial structural distortions can affect carrier mobility and device reliability. In this work, we investigate thermally...

Eco‐Designed Transparent Bacterial Cellulose Composites for Next‐Generation Opto‐Electronics

ABSTRACT Sustainable, bio‐based alternatives to petrochemical substrates are essential for the fabrication of next‐generation optoelectronic devices. However, very few natural materials offer simultaneously high transparency, mechanical robustness, and functional versatility. Bac...

Toroidal quasi-dark supermodes in microwave dielectric metasurfaces

We report a class of dielectric metasurfaces that support quasi-dark microwave resonances with tailored toroidal and antitoroidal field profiles. The metasurfaces are realized using quadrumers of high-permittivity and low-loss ceramic disk resonators as elementary building blocks...
