Graphene is prepared from graphite by pressurized oxidation and multiplex reduction. The advantageous in easy operation size-control, the reduction, based on ammonia hydrazine, produces single-atom-thick graphene (0.4–0.6 nm thick) which can be directly observed atomic force microscopy. A masterbatch strategy, feasible "soluble" thermoplastic polymers, developed to disperse into poly(lactic acid) melt blending. well dispersed obtained nanocomposites present markedly improved crystallinity,...

Polymer/graphene nanocomposites have generated intensive interest due to their unique properties. Dispersion and interface interactions between graphene the polymer matrix are two key factors obtain property enhancements. According open literature, in poly(vinyl alcohol) (PVA) nanocomposites, usually obtains more significant enhancements than graphite oxide (GO), although GO can much easily form a good dispersion strong interaction PVA because of its oxygenated functionalities, reason has...
The influence of the Coulomb interaction on one and two electron-hole-pair excitations in semiconductor quantum dots is analyzed. Using a numerical matrix-diagonalization scheme, energy eigenvalues eigenfunctions relevant states are computed. Significant deviations from strong-confinement approximation observed. It shown that biexciton binding increases with decreasing dot size. This result verified using third-order perturbation theory for small dots. optical properties computed, it...
