Strategies for regulating the electronic structure of transition-metal-based electrocatalysts through doping, heterostructure, oxygen vacancies, alloy, and strain engineering are investigated.

the thin gelatin films, prepared by casting of gelatin solutions at different drying temperatures, had different molecular morphologies as monitored, using wide angle x-ray diffraction (waxd) and differential scanning calorimetry (dsc) techniques. it was revealed that gelatin films dried at lower temperatures showed markedly higher crystalline or helical structure with slightly higher tg and lo...
