title: Material self-assembly as a physicochemical process.
abstract: Material self-assembly as exemplified in protobiogeneses is shown to be result of molecular exchange interaction in reacting chemicals. Temporally and spatially correlated aggregates of reacting chemicals work as vertices of molecular exchange interaction. If the material accumulation rate at a locally correlated aggregate spontaneously happens to become positive at a certain time, the material accumulation due to self-assembly will increase with time afterward. A spontaneous formation of looped reaction at locally correlated aggregates of reacting chemicals can initiate a material self-assembly at succeeding times.
