Modelling of gas permeation through ceramic coatings produced by thermal spraying
An analytical model has been developed for simulation of gas permeation through thermal spray coatings, and for prediction of the permeability. The model is based on a geometrical representation of the coating microstructure.

Gas evolution behaviors of sodium layered oxide cathodes with varying compositions, cutoff voltages, dopants, and particle sizes/morphologies have been systematically investigated by online electrochemical mass spectrometry. The fundamental outgassing mechanisms of sodium‐based cathodes compared to lithium‐based cathodes have been elucidated.

Lithium‐ion batteries are ubiquitous but pose significant safety risks especially with high‐energy‐density electrode materials. This study reports a nanocomposite gel electrolyte (NGE) with a flame‐retardant magnesium hydroxide (MH) matrix, which offers robust mechanical properties, high ionic conductivity, and enhanced thermal safety.

The densification process of Li6PS5Cl powders with varying particles size distributions reveals differences in smaller and larger distributions. Higher strain is revealed for the smaller particle size distribution from X‐ray diffraction. Discrete element method simulations uncover that the reason for the higher strain is not the particle size itself ...

This graphical abstract emphasizes the working principle and the various essential factors of the direct methanol fuel cell (DMFCs). Additionally, various parameters, such as the nanoparticle's size and shape, the nature of the electrolyte, the type of support materials, and their fabrication process, also play essential roles in the functioning of the

An experimental framework is introduced to isolate single‐impact and cumulative energy within a mechanochemical system. The guided, stepwise approach highlights the fundamental roles of impact events, post‐impact reactivity, and liquid‐assisted grinding additives in all‐solid mechanochemical reactions.
