  • Patent number: 10099965
    Abstract: Carbon opals, a form of colloidal crystal, are composed of ordered two-dimensional or three-dimensional arrays of Monodispersed Starburst Carbon Spheres (MSCS). Methods for producing such carbon opals include oxidizing as-synthesized MSCS, for example by heating in air, to increase surface charge. Such oxidation is believed to decrease settling rates of a colloidal suspension, enabling formation of an ordered colloidal crystal. Inverse opals, composed of any of a wide variety of materials, and based on a carbon opal template, have a reciprocal structure to a carbon opal. Inverse opals are formed by methods including: forming a carbon opal as described, impregnating a desired material into pores in the carbon opal to produce a hybrid structure, and removing the carbon portion from the hybrid structure.

  • Patent number: 9354354
    Abstract: Processes of forming an irreversibly loose packed structure of particulate material useful as a photonic or phononic crystal are provided. Matrix material is infilled between particles and extends above the particles to form a particulate free matrix layer. Removing the matrix layer causes deformation of or exposes the spacing between the particles. The spaces are infilled by additional matrix material that when cured produces a supported and irreversibly loose packed crystalline structure of particles producing differing bandgaps and transmissive properties relative to the original structure. The processes provided allow for economical tuning of the transmissive properties of photonic or phononic crystals.

  • Patent number: 6619071
    Abstract: In an adsorption-type refrigerating apparatus, an adsorber includes therein an adsorbent having a temperature-dependent characteristic in which an amount adsorbed in an adsorption step is larger than an amount adsorbed in a desorption step, even when a vapor pressure rate in the adsorption step is equal to or lower than a vapor pressure rate in the desorption step. Therefore, even when the cooling temperature of outside air for cooling the adsorbent increases, a sufficient cooling capacity can be obtained. In addition, a difference between the amount adsorbed in the adsorption step and the amount adsorbed in the desorption step can be made larger.

    Abstract: Porous materials having a metal oxide skeleton are taught that have various water vapor adsorption capacities defined by the amount of adsorbed water vapor at a specific relative vapor pressure in a water vapor adsorption isotherm. A preferred porous material has a water vapor adsorption capacity that is less than or equal to 0.1 g/g at a relative vapor pressure of 10%, and greater than or equal to 0.2 g/g at a relative vapor pressure of 28%. Methods of making such porous materials are also taught. A preferred method for forming a porous material includes condensing a skeleton starting material for the porous material, in the presence of a surfactant, in a solution which has a concentration of the skeleton starting material in the solution that is less than or equal to 0.4 mol/L and a molar ratio of the surfactant to the skeleton starting material that is greater than or equal to 0.05 and less than or equal to 50, to form a condensate and removing the surfactant from the condensate.

  • Patent number: 5756628
    Abstract: The present invention provides an inorganic-organic hybrid material having both the characteristics of the inorganic material and the characteristics of the organic material. The material has a lamellar structure formed by piling a sheet of silicon tetrahedrons upon a sheet of titanium octahedrons. In this lamellar structure, an organic group is bonded to a center atom of a tetrahedron via a covalent bond. The organic group can be polymerized to make the organic phyllotitanosilicate a tough and hard coating material. The hybrid material of the present invention thus has both the characteristics, such as high hardness and heat resistance, of the constitutive inorganic material and the characteristics, such as flexibility and filmability at room temperature, of the constitutive organic material, and further has an excellent UV-blocking property.

  • Patent number: 5164460
    Abstract: Disclosed herein is a polyimide composite material which comprises a polyimide-containing resin and a layered clay mineral which is intercalated with organic onium ions and dispersed in the polyimide. Owing to the intercalated clay mineral, the composite material has improved gas and water vapor barrier properties and a small thermal expansion coefficient. Disclosed also herein is a process for producing a polyimide composite material which comprises the steps of intercalating a layered clay mineral with organic onium ions, adding by mixing the intercalated clay mineral to a solution of a monomer or prepolymer for polyimide, removing the solvent, and forming a polyimide. This process makes the layered clay mineral miscible with and dispersible in polyimide.
