  • Patent number: 6824776
    Abstract: This disclosure describes the first viable non-enzyme protein encapsulated within an aerogel. In this, a large excess of cyt. c is added to a commercial buffered Au sot solution ( ) which results in the formation of a gold˜protein-protein superstructure in the absence of separation techniques which destroy the superstructure. The gold˜protein-protein superstructure is then nanoglued into a silica framework during the sol to gel transition. To form the gel, the Au-cyt. c superstructure in buffered medium is added to a silica sol and the composite gels are washed with acetone followed by liquid carbon dioxide and then supercritically dried to form the aerogel. The biocomposite aerogels have a multiplicity of applications particularly in the realm of sensing and energy transformation.

  • Patent number: 6806299
    Abstract: Synthetic methods for the preparation of hydrophobic organics aerogels. One method involves the sol-gel polymerization of 1,3-dimethoxybenzene or 1,3,5-trimethoxybenzene with formaldehyde in non-aqueous solvents. Using a procedure analogous to the preparation of resorcinol-formaldehyde (RF) aerogels, this approach generates wet gels that can be dried using either supercritical solvent extraction to generate the new organic aerogels or air dried to produce an xerogel. Other methods involve the sol-gel polymerization of 1,3,5 trihydroxy benzene (phloroglucinol) or 1,3 dihydroxy benzene (resorcinol) and various aldehydes in non-aqueous solvents. These methods use a procedure analogous to the one-step base and two-step base/acid catalyzed polycondensation of phloroglucinol and formaldehyde, but the base catalyst used is triethylamine. These methods can be applied to a variety of other sol-gel precursors and solvent systems.

  • Patent number: 6797733
    Abstract: A process of producing expandable styrene resin particles, wherein in suspension polymerization of styrene monomers, the concentration of oxygen in a reaction vessel is kept low at least in a late stage of the polymerization, and the resulting styrene resin particles are impregnated with an expanding agent before or after completion of the polymerization. Preferably, at a polymerization rate of 60% or higher, the concentration of oxygen in the reaction vessel is kept at 7 vol % or lower. When additional styrene monomers are added during the polymerization, they are added and adsorbed to styrene resin particles in the course of polymerization while the concentration of oxygen is kept low. By this method, the particles whose internal portion has a low molecular weight and surface portion has a high molecular weight are obtained. A foamed article produced from the particles has high strength and a good appearance.
