The contribution from boundary diffusion at the grain boundaries decreases with increasing nanowall size [31].
The activation energy was close to that for grain boundary diffusion at 523 573 K, and was close to that for lattice diffusion at 598 673 K.
During compression, the deformation of the nanometer size bcc particles occurs by grain boundary sliding accommodated by flow controlled by grain boundary diffusion at room temperature.
The results of the optimization analysis show that higher current densities at the membrane/cathode interface are obtained in the PEM cathode and the interdigitated air distributor geometries that promote convective oxygen transport to the membrane/cathode interface and reduce the thickness of the boundary diffusion layer at the same interface.
The results show that round, scallop-type Cu6Sn5 grains with a strong texture form at the molten solder/Cu interface and that their growth is controlled more by grain boundary (GB) diffusion at the beginning of the reaction followed by volume diffusion, whereas the growth of Cu3Sn is only volume-diffusion-controlled.
