Hydrogen has the physical and chemical characteristics of being flammable, explosive prone to leakage, its safety is main issue faced by promotion hydrogen as an energy source. The most common scene in vehicle application longitudinal wind generated driving, original position concentration sensors (HCSs) did not consider influence on leakage trajectory. In this paper, computational fluid dynami...

Lanthanide perovskite oxides are mentioned as material for hydrogen peroxide sensor because they can catalytically decompose hydrogen peroxide in an aqueous medium. The catalytic properties of these perovskite oxides to hydrogen peroxide are suggested due to their oxygen vacancies influenced by the oxide non-stoichiometry. In this paper, we investigate the catalytic hydrogen peroxide decomposit...
