Title: Kinetic arrest, dynamical transitions, and activated relaxation in dense fluids of attractive nonspherical colloids. Author: Zhang R, Schweizer KS. Journal: Phys Rev E Stat Nonlin Soft Matter Phys; 2011 Jun; 83(6 Pt 1):060502. PubMed ID: 21797291. Abstract: The coupled translation-rotation activated dynamics in dense suspensions of attractive homogeneous and Janus uniaxial dicolloids are studied using microscopic statistical mechanical theory. Multiple kinetic arrest transitions and reentrant phenomena are predicted that are associated with fluid, gel, repulsive glass, attractive glass, plastic glass, and novel glass-gel states. The activated relaxation rate is a nonuniversal nonmonotonic function of attraction strength at high volume fractions due to the consequences of a change of the transient localization mechanism from caging to physical bonding.[Abstract] [Full Text] [Related] [New Search]
