Electronic Modulation of Pt Nanoparticles Induced by Defective TiN Promotes Highly Efficient Hydrogen Evolution

open access: yesCarbon Energy, EarlyView.
A nonequilibrium high‐temperature shock method was used to load Pt nanoparticles onto nitrogen vacancy‐rich TiN, enabling strong EMSI modulation. The Pt@TiN‐VN catalyst shows high HER activity (15.99 A mgPₜ⁻¹ at 100 mV) and 60‐h stability. Nitrogen vacancies optimize charge transfer and Pt–H bonding, offering insights into defect‐engineered ...

Investigation of counter-rotating shock wave and wave direction control of hollow rotating detonation engine with Laval nozzle

The Physics of Fluids, 2022
The counter-rotating shock wave and wave direction control of the hollow rotating detonation combustor with Laval nozzle are studied. The in-house solver BYRFoam, developed on the OpenFOAM platform, is used. The phenomenon and spatial distribution of the

Stratification effect of air bubble on the shock wave from the collapse of cavitation bubble

Journal of Fluid Mechanics, 2021
This paper presents an experimental study on the mechanism of interaction between a cavitation bubble and an air bubble. The cavitation bubble was generated by means of the low-voltage discharge method, and the combination of high-speed photography and a

Wave-function shock waves

Physical Review A, 1992
When a Rydberg state is suddenly excited to an autoionizing Rydberg state by a short-pulse core-electron excitation, a shock wave is created in the Rydberg electron's wave function. This shock wave originates at small r, at the excited core, and propagates outward.

Interstellar Shock Waves

Science, 1991
An understanding of interstellar shock waves is crucial in determining the structure of the interstellar medium. By causing the gas to radiate, interstellar shocks provide astronomers with valuable diagnostics on both the physical conditions in the interstellar medium and the energy source that produced the shock.
