In anion exchange membrane fuel cells, catalytic reactions occur at a well-defined three-phase interface, wherein conventional heterogeneous catalyst layer structures exacerbate problems, such as low catalyst utilization and limited mass transfer. We developed a structural engineering strategy to immobilize a molecular catalyst tetrakis(4-methoxyphenyl)porphyrin cobalt(II) (TMPPCo) on the side chains of an ionomer (polyfluorene, PF) to obtain a composite material (PF-TMPPCo), thereby achieving a homogeneous catalysis environment ins

A cat flap made of UPVC is a great option to allow your cats to come and go as they please. It's a simple three-step installation procedure and can be fitted into glass doors, wooden doors or UPVC panels. It is an excellent choice for pet owners who want to ensure their pets' safety and reduce energy costs. can resist moisture, heat, and UV. Easy to install Installing a pet flap onto your glass door or glass panel is a great idea if
