Electron pairing instabilities and magnetic properties in nanoclusters and nanomaterials

Kocharian A.N., Fernando G.W., Fung K., Palandage K., California State University Los Angeles, US

Studies of assembled clusters, nanoparticles and optical lattices in various topologies provide intriguing insights into several many body problems in condensed matter physics1. A new, emerging guiding principle for the search of new materials can [...]

Morphology and Phase Transitions in Styrene-Butadiene-Styrene Triblock Copolymer Grafted with Polyhedral Oligomeric Silsesquioxanes

Drazkowski D.B., Lee A., Michigan State University, US

Two symmetric triblock copolymers of polystyrene-butadiene-polystyrene (SBS) with different styrene content were grafted with varying amounts of polyhedral oligomeric silsesquioxane (POSS) molecules with either isobutyl or phenyl moiety. The POSS octamers, R’R7Si8O12 were designed to [...]

Computer Molecular Dynamics and Phase Transition in Alkali Azides and Thiocyanates

Ossowski M.M., Hardy J.R., University of Nebraska, US

An account is presented of our studies of the order-disorder phase transitions in KN3, RbN3, CsN3, KSCN, RbSCN and CsSCN. These are based on parameter-free inter-ionic potentials based on the Gordon-Kim modified electron gas formalism [...]
