Depletion forces in nonequilibrium.
The concept of effective depletion forces between two fixed big colloidal particles in a bath of small particles is generalized to a nonequilibrium situation where the bath of small Brownian particles is flowing around the big particles with a prescribed velocity. In striking contrast to the equilibrium case, the nonequilibrium forces violate Newton's third law; they are nonconservative and str...
متن کاملUnderstanding Depletion Forces beyond Entropy
The effective interaction energy of a colloidal sphere in a suspension containing small amounts of nonionic polymers and a flat glass surface has been measured and calculated using total internal reflection microscopy and a novel approach within density functional theory, respectively. Quantitative agreement between experiment and theory demonstrates that the resulting repulsive part of the dep...
متن کاملPolymer Depletion Forces and Surfactant Adsorption
Introduction Lung surfactant is a mixture of lipids, primarily dipalmitoylphosphatidylcholine, and several specific proteins, that lines the interior of the lung alveoli. Lung surfactant lowers the interfacial tension in the lungs, thereby insuring a negligible work of breathing and uniform lung inflation. The absence of lung surfactant in premature infants leads to neonatal Respiratory Distres...
متن کاملMicroscopic Origin of Casimir-Polder Forces
Abstract. We establish a general relation between dispersion forces. First, based on QED in causal media, leading-order perturbation theory is used to express both the single-atom CasimirPolder and the two-atom van der Waals potentials in terms of the atomic polarizabilities and the Green tensor for the body-assisted electromagnetic field. Endowed with this geometryindependent framework, we the...
متن کاملDesolvation is a likely origin of robust enthalpic barriers to protein folding.
Experimental data from global analyses of temperature (T) and denaturant dependence of the folding rates of small proteins led to an intrinsic enthalpic folding barrier hypothesis: to a good approximation, the T-dependence of folding rate under constant native stability conditions is Arrhenius. Furthermore, for a given protein, the slope of isostability folding rate versus 1/T is essentially in...
