Propane dehydrogenation is an important field of research due to increasing world-wide demand propene while classical production routes through naphtha cracking are in decline. In that context, silica-supported Ga(III) sites, synthesized from surface organometallic chemistry principles, show high selectivity and stability the propane reaction. This performance significant contrast reported fast...

Hard chromium coatings have demonstrated their performance for several decades, particularly wear and corrosion resistance properties. However, the traditional process using trioxide (CrO3) is very toxic intended to disappear in European Union by 2024, thanks REACH regulation. This study aimed determine residual stress of amorphous deposits elaborated from baths containing trivalent ions. struc...
