Computational screening of transition metal-doped CdS for photocatalytic hydrogen production

npj Computational Materials, 2022
A novel computational screening study of single transition metal (TM), TM-doped, and dual TMs-doped on CdS (110) surfaces via DFT calculations is presented, focusing on their stability and catalytic activity, searching for efficient photocatalysts for ...

Investigation on the physical and electrochemical properties of typical Ni-based alloys used for the bipolar plates of proton exchange membrane fuel cells

Heliyon, 2023
The phase, mechanical properties, corrosion resistance, hydrophobicity, and interface contact resistance of three typical Ni-based alloys (Hastelloy B, Hastelloy C-276, and Monel 400) and 304 stainless steels were experimentally studied to evaluate their

Modelling ultrasound waves bubble formation in ethanol/ethyl acetate azeotrope mixture [PDF]

E3S Web of Conferences, 2019
The separation of an azeotropic mixture such as ethanol/ethyl acetate in distillation process can be enhanced by ultrasound wave. The application of ultrasound wave creates bubble cavitation in the mixture and shifts the vapour-liquid equilibrium ...

Low Cycle Fatigue Crack Damage Behavior of TC21 Titanium Alloy with Basketweave Microstructure

Crystals, 2022
Low cycle fatigue (LCF) crack initiation, propagation and damage behaviors of TC21 alloy with basketweave microstructure were investigated. The process of LCF damage was observed by a long-focus optical microscopic imaging system, and fatigue crack ...

Hydrogenic entanglement [PDF]

New Journal of Physics, 2020
Abstract Is there any entanglement in the simplest ubiquitous bound system? We study the solutions to the time-independent Schrödinger equation for a hydrogenic system and devise two entanglement tests for free and localised states. For free hydrogenic systems, we compute the Schmidt basis diagonalisation for general energy eigenstates ...

Hydrogen microstructure in hydrogenated amorphous silicon [PDF]

Physical Review B, 1996
We present a method to determine the local hydrogen bonding structure in hydrogenated amorphous silicon from infrared spectroscopy measurements. This approach is based on a different oscillator strength and refractive index for hydrogen atoms located in the isolated and clustered phase.

Ionization of Hydrogen and Hydrogenic Ions by Antiprotons [PDF]

Physical Review Letters, 1996
Presented here is a description of the ionization of hydrogen and hydrogenic ions by antiproton-impact, based on very large scale numerical solutions of the time-dependent Schr dinger equation in three spatial dimensions and on analysis of the topology of the electronic eigenenergy surfaces in the plane of complex internuclear distance.

Interaction vesicles as emerging mediators of host‐pathogen molecular crosstalk and their implications for infection dynamics

FEBS Letters, EarlyView.
Interaction extracellular vesicles (iEVs) are hybrid vesicles formed through host‐pathogen communication. They facilitate immune evasion, transfer pathogens' molecules, increase host cell uptake, and enhance virulence. This Perspective article illustrates the multifunctional roles of iEVs and highlights their emerging relevance in infection dynamics ...
