Progress in nonequilibrium physics, as in all of condensed-matter and materials physics, will depend on our ability to bridge cultures. We shall have to understand the importance of, and the impediments facing, our efforts to bring new science to bear on technology and to take advantage of new technologies to advance basic science.

We study the structure and dynamics of semidilute solutions of semiflexible polymers at rest and under shear using hybrid molecular dynamics simulations that take hydrodynamic interactions into account.

We show that the polymer center-of-mass diffusion coefficient significantly decreases with increasing chain stiffness at fixed monomer by: 9. modynamic equilibrium. Because of their entangled nature, however, dense macromolecular systems may not always reach equilibrium in practical set-tings.

My conference contribution will discuss two scenarios, where the prop-erties of macromolecular melts are determined by the interplay of thermody-namic and kinetic processes.

To fulfill those complex roles, RNA and protein macromolecular evolves a great complexity in their structures. From strand to helices and sheets, their structures consist of many levels of sub-modules, like program libraries.

By combining these sub-modules, protein and RNA molecular work together as Author: Zhiyong Wang.
