change. The ordered assembly of indestructible atoms into small and largemolecules, or extended networks of intermingled atoms, is generally accepted as the basis of permanence, while the reorganization of atoms or molecules into different arrangements lies behind theories of change. Thus chemistry ...
on the scale of the equipment. This makes it increasingly necessary, due to the increased development of more active and selective catalysts, to quantitatively understand the change of the flow pattern with reactor scale and the interaction of it with mesoscale transport. Hence, moving the level ...
