摘 要：The problem of molecular diffusion in the soup of chemical reactions attracts mounting interest across fields ranging from chemistry to biophysics to material *** reactions involve bond breakup and formation,whose time scale is typically on the orders of fs to ps,while molecular diffusion occurs at time scales ofμs to *** two processes are often considered orthogonal,given the vastly different *** serial results show that the enzyme s diffusion is enhanced in a substrate-dependent manner,which was further extended to small molecule reaction systems,challenging this classical ***,the results from different groups using different techniques do not quantitatively agree,and a general mechanism is yet to be *** summarize experimental studies on diffusion problems and seek to reconcile the interpretation with understanding the limits of measurement tools and the chemical nature of reaction *** molecular diffusion in chemical reactions will provide fresh thoughts in designing chemical systems such as molecular machines that harvest work at the nanoscale in a controllable manner.
