We have carried out calculations of the electronic structure of ferredoxin and of the electronic coupling matrix element Hif for electron transfer from reduced ferredoxin to flavin adenine dinucleotide (FAD) and to cluster models of the Au111 surface and a Au111 surface with a mercaptopyridene self-assembled monolayer (SAM). Solvent-vapor based bonding of micro-molded layers preserved 20 microm sized structures. Product Solid-state battery We also believe that the sustained kinetics for the fully mixed cermet layer sample stems from better thermal stability of Pt islands separated by the ALD YSZ matrix, which helped to maintain the high-density TPBs even at elevated temperature.
