  • Publication number: 20080234395
    Abstract: The present invention provides a viscous dispersion comprising crystalline semiconductor nanoparticles, which is useful for formation of a porous semiconductor membrane of high purity at a low temperature. The viscous dispersion comprises crystalline semiconductor nanoparticles dispersed in a dispersion medium, wherein the dispersion medium is a mixture comprising 53 to 92 wt % of a hydrophilic organic medium and 8 to 47 wt % of water, said hydrophilic organic medium comprising an alcohol having 3 to 5 carbon atoms as a main component, wherein the dispersion medium essentially does not contain an organic binder, an amount of said organic binder being less than 2 wt % of the medium, and wherein the dispersion comprises 8 to 40 wt % of the dispersed crystalline semiconductor nanoparticles based on the total amount of the dispersion.

  • Publication number: 20080182960
    Abstract: The present invention is drawn to surface-crosslinked latex particulates, corresponding latex suspensions, ink-jet inks, and methods for making the latex particulates. A latex suspension can include a fluid medium and surface-crosslinked latex particulates. The surface-crosslinked latex particulates can be devoid of substantially all crosslinking below the particulate surface. Such surface-crosslinked latex particulates can be prepared with a plurality of monomers and at least one crosslinking agent.

  • Publication number: 20080146680
    Abstract: A particulate silver powder has an average particle diameter measured by TEM observation (DTEM) of 200 nm or less, an aspect ratio of less than 2.50, and a {(DTEM)/(Dx)} of 5.0 or less (where (Dx) denotes X-ray crystallite size). The particulate silver powder has a content of each of I?, Cl?, SO42?, NO3? and CN? of 100 ppm or less. The particulate silver powder is obtained by subjecting a silver compound other than silver nitrate to reduction in an organic solvent having a boiling point of 85° C. or greater at a temperature of 85° C. or greater and in the presence of an organic protective agent.

  • Patent number: 7314584
    Abstract: The present invention provides a polymer gel composition including: at least two polymer compounds which interact with each other to form a polymer complex; and a liquid. One of the polymer compounds forms a three-dimensional crosslinked structure, at least one other polymer compound is compatible with the liquid, and at least a portion of the compatible polymer compound is included in the three-dimensional crosslinked structure. Preferably, when the polymer complex is disassembled or decomposed by stimuli, the polymer compound forming the three-dimensional crosslinked structure changes its volume by absorbing or releasing the liquid. The three-dimensional crosslinked structure is preferably in a particle shape. An optical device using such a polymer gel composition is also provided.
