Investigation on a novel SiC Schottky barrier diode hydrogen sensor with trench-insulator structure

Materials Research Express, 2021
A novel SiC Schottky barrier diode (SBD) hydrogen gas sensor with trench-insulator structure was proposed in this paper. A physical model is built for this hydrogen sensor based on 4H-SiC SBD thermionic emission theory, tunneling effect of carriers ...

Self‐Supported SiC@Graphene Porous Array Electrodes for Ultrastable Supercapacitors

Electron, EarlyView.
Self‐supported SiC–graphene porous array electrodes are fabricated through a novel steam‐assisted etching and in situ pyrolysis strategy. They deliver a high energy density of 4.9 μWh cm−2 at 150°C with 89.55% capacitance retention over 10,000 cycles, presenting a new approach for high‐temperature supercapacitors.

Temperature dependence of the thermo-optic coefficient in 4H-SiC and GaN slabs at the wavelength of 1550 nm

Scientific Reports, 2022
The refractive index and its variation with temperature, i.e. the thermo-optic coefficient, are basic optical parameters for all those semiconductors that are used in the fabrication of linear and non-linear opto-electronic devices and systems. Recently,

Widespread complex enameloid microstructure in teeth and rostral denticles of Cretaceous sclerorhynchoid skates (Rajiformes: †Sclerorhynchoidei)

Journal of Anatomy, EarlyView.
This article demonstrates that the teeth and rostral denticles of an extinct clade of sawfish‐like skates display an extremely derived enameloid microstructure, similar to what is known among sharks. The presence of tooth‐like enameloid microstructure in dermal denticles opens new perspectives about the origins and development of chondrichthyan ...

Bio‐Inspired Robust Non‐combustible Bioplastic with Superinsulated Energy Harvesting for Intelligent Firefighting

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
This study develops a novel non‐combustible chitosan‐based bioplastic (NCCB) via ethanol‐induced surface assembly. The material's inherent flame retardancy and thermally insulating, rough surface enable high‐performance TENGs. The NCCB‐TENG maintains stable output even when exposed to fire and exhibits dual sensitivity to temperature (25–200°C) and ...
