The key dilemma for green hydrogen production via electrocatalytic water splitting is the high overpotential required for anodic oxygen evolution reaction (OER). Co/Fe‐based materials show superior catalytic OER activity to noble metal‐based catalysts, but still lag far behind the state‐of‐the‐art Ni/Fe‐based catalysts probably due to undesirable side segregation of FeOOH with poor conductivity and...
Extracellular vesicle (EV)‐based therapies have emerged as a promising means in regenerative medicine. However, the conventional EV therapy strategy displays some limitations, such as inefficient EV production and lack of tissue‐specific repair effects. Here, it is reported that neonatal‐tissue‐derived EV therapy (NEXT) is a potent strategy for precision tissue repair. In brief, large amounts of EVs...
