Boundary free energy

Perhaps the most striking result of the measurements of the ratio 7, /7S is that so many values of it are confined to the range 0.25—0.40. As a matter of fact, an earlier review50 refers to the general observation that the grain-boundary free energy is about one-third of the solid-surface free energy. Also in a latter study on UC, the ratio 71 /ys was found to vary between 0.36 and 0.41116. Because so much... 

The 13C nuclear resonance studies in my report provide some informations on lipid membrane fluctuations in binary mixtures. Totally unsolved problems include an appropriate two-dimensional Debye-Huckel theory for membranes, and theoretical treatments of boundary free energies (between proteins and lipids, and between solid and fluid phase lipids).

Roll-up. The principal means by which oily soil is removed is probably roU-up. The appHcable theory is simply the theory of wetting. In briefest outline, a droplet of oily soil attached to the substrate forms at equiUbrium a definite contact angle at the oil-sohd-air boundary line. This contact angle (Fig. 4) is the result of the interaction of interfacial forces in the three phase boundaries of the system. These interfacial forces, expressed in mN/m(= dyn/cm), or interfacial free energy values expressed in mj/m (erg/cm s) are conveniently designated 1SA iSlj subscripts relate to the Hquid-air,...
