A Histidine-Mediated, Pendulum-Like Proton Transport Mechanism Is Required for the High Catalytic Activity of [FeFe]-Hydrogenases

Abstract [FeFe]-hydrogenases are molecular hydrogen (H2) converting enzymes that employ a hexanuclear iron complex, the H-cluster, as the catalytic cofactor, and a proton transfer pathway (PTP) that enables efficient proton-coupled electron transfer (PCET). Recent phylogenetic an...

Phase change material-based thermal management systems for PEM fuel cell/battery hybrid electric vehicles: A comprehensive review

Proton exchange membrane fuel cell/battery hybrid electric vehicles (FCHEVs) require efficient thermal management because multiple onboard subsystems operate over different temperature ranges while exhibiting strong thermal interactions. Phase change materials (PCMs), owing to th...
