Novel Physical Pictures of Protein Partitioning in Two-Phase Aqueous Polymer Systems... [Pg.57]

While the goal of the previous models is to carry out analytical calculations and gain insight into the physical picture, the multidimensional calculations are expected to give a quantitative description of concrete chemical systems. However at present we are just at the beginning of this process, and only a few examples of numerical multidimensional computations, mostly on rather idealized PES, have been performed so far. Nonetheless these pioneering studies have established a number of novel features of tunneling reactions, which do not show up in the effectively one-dimensional models. [Pg.11]

Straightforward analytical models, however, receive particular attention in the present book, as they are of unique significance in the comprehension of physical phenomena and, moreover, provide the very language to describe them. To exemplify, recall the effect caused on the phase transition theory by the exactly soluble two-dimensional Ising model. Nor can one overestimate the role of the quasiparticle concept in the theory of electronic and vibrational excitations in crystals. As new experimental evidence becomes available, a simplistic physical picture gets complicated until a novel organizing concept is created which covers the facts known from the unified standpoint (thus underlying the aesthetic appeal of science). [Pg.2]

Chemists have synthesized a spectacular array of submicron- and nano-particles with well-defined size and atomic structure and very special properties. Examples include CdSe quantum dots and novel spheres and rods. Transport enters the picture via fundamental studies of the physical processes that affect the synthesis, which must be understood for even modest scale-up from the milligram level. Likewise, processes for assembling fascinating face-centered-cubic crystals or ordered multilayers must concentrate on organizing the particles via flow, diffusion, or action of external fields. Near-perfection is possible but requires careful understanding and control of the forces and the rates. [Pg.51]

Professor Chang has served on the American Chemical Society Examination Committee, the National Chemistry Olympiad Examination Committee, and the Graduate Record Examinations (GRE) Committee. He is an editor of The Chemical Educator. Professor Chang has written books on physical chemistry, industrial chemistry, and physical science. He has also coauthored books on the Chinese language, children s picture books, and a novel for young readers. [Pg.1141]

An increase in the accuracy of creep measurements has always been of importance but recently it has become a focal research problem for two reasons. First, the development of novel highly precise instruments for measuring creep rates is necessary in the context of increased interest in studies being performed on the micro-, submicro-, and even nano-levels. Second, it may a priori be assumed that creep behavior of polymeric materials is associated intimately with their basic physical characteristics, namely, molecular dynamics and supermolecular structure. However, the common widespread methods of the deformation measurements provide a rather smoothed picture and often allow no discerning of the fine effects depending on the changes in dynamics and structure of materials. [Pg.78]
