  • Patent number: 9828510
    Abstract: The present invention is a composition comprising a solution or a dispersion of polymer particles, a sorbate ester or sorbamide curing agent, and a cure modulating additive for the curing agent. The curing agent is a sorbic acid ester or a sorbamide and the cure modulating agent is a reagent capable of accelerating or attenuating the rate of cure of the curing agent. The control of cure kinetics is important for speeding up cure rates where rates are too slow or by reducing cure rates where curing too rapidly results in undesirable color formation.

  • Patent number: 8036864
    Abstract: A method for predicting the formation of silicon nanocrystals in an oxide matrix is disclosed. Initially, fundamental data for a set of microscopic processes that can occur during one or more material processing operations are obtained. Kinetic models are then built by utilizing the fundamental data for a set of reactions that can contribute substantially to the formation of silicon nanocrystals in a silicon oxide matrix. Finally, the kinetic models are applied to predict shape, size distribution, spatial arrangements of silicon nanocrystals.

  • Publication number: 20100119434
    Abstract: Methods for the formation of nanotube from thin films are provided. The methods involve the adsorption of atoms to the surface of the films. The adsorbed atoms introduce surface stress, inducing a curvature in the films. The curvature is sufficient to bring atoms at the edges into sufficiently close proximity to form covalent bonds. Other methods include the step of desorbing the atoms from the surface of the film. The films may comprise a variety of nanomaterials, including graphene sheets and semiconductor thin films.
