Web1 dag geleden · Understanding how multicopper oxidases (MCOs) reduce oxygen in the trinuclear copper cluster (TNC) is of great importance for development of catalysts for the oxygen reduction reaction (ORR). Herein, we report a mechanistic investigation into the ORR activity of the dinuclear copper complex [Cu2L(μ-OH)]3+ (L = 2,7-bis[bis(2 … WebIn this model there are energy levels for the nucleons which are slightly different for the protons and for the neutrons. Each energy level can be occupied by two particles of the same type and so when the bottom energy level (shell) is filled with 2 neutrons and 2 protons a very stable nucleus is formed $(^4_2 \rm He)$. black stitched shirts
