WebResearch is very promising for how alkaline water can benefit brain disease. The results of a 2011 study titled “The neuroprotective effects of electrolyzed reduced water (ERW) containing molecular hydrogen and Pt nanoparticles” suggest that it is “beneficial for the prevention and alleviation of oxidative stress-induced human neurodegenerative diseases.” WebApr 12, 2024 · Notably, the reported overpotential outmatched the state-of-the-art (Pt) HER catalyst. Furthermore, inspired by the biomimetic molecular compounds with a hetero-cubane architecture of a general formula (Ni/Co 4− x Zn x O 4 ; x = 1–3), we synthesized novel oxide materials to investigate their electrocatalytic behavior during OER.
