  • Publication number: 20120282316
    Abstract: Sol-gel inorganic porous particles are composed of an inorganic compound that provides an inorganic solid phase including an external particle surface. They also have a first set of pores wherein the pores have an average diameter of less than 100 nm and a second set of pores wherein the pores have an average diameter of at least 100 nm, which second set of pores contains stabilizing organic microgel particles. These inorganic porous particles are prepared using a first oil phase comprising a first water-immiscible aprotic solvent having a dielectric constant of less than 10 and having dissolved therein organic microgel particles. An aqueous phase comprising a polar solvent, an inorganic gel precursor, a catalyst, and a dispersing surfactant is neutralized to initiate condensation of the inorganic gel precursor. An oil-in-water emulsion is then formed with the organic microgel particles in the first oil phase, which is dispersed as first oil phase droplets in the aqueous phase.

  • Publication number: 20120009425
    Abstract: Size-controlled immobilization of metal nano-clusters onto particles or nanoparticles is achieved using a polyol process. Polyol processing makes it possible to use thiol groups as a chemical protocol to functionalize the surface of particles, such as silica and polystyrene nanoparticles. Metal nano-clusters, such as silver, gold, platinum and palladium, nucleate and grow on the surface of the particles. The metal nano-clusters may be synthesized in a one-pot process from metal salts, nitrates, nitrites, sulfates, sulfites and the like. Any source of metal ions compatible with the polyol suspension and selected particles may be used. The size of immobilized metal nano-clusters may be controlled by additions of a poly(vinylpyrrolidone) or other polymer capable of regulating the metal ion reduction and nucleation process and by controlling concentration of metal ions, the nucleation and/or growth temperatures, and processing time.

    Abstract: A process has been found which increases the efficiency and effectiveness of introducing antimicrobial compounds into complex biofilm matrices through the use of liposome carriers, thereby removing the biofouling in industrial water bearing systems, including piping, heat exchanges, condensers, filtration systems and fluid storage tanks. According to one embodiment of the invention, antimicrobial compound containing liposomes are added to water systems prone to biofouling and biofilm formation. The liposomes, being similar in composition to microbial membranes or cells, are readily incorporated into the existing biofilm. Once the antimicrobial compound containing liposomes become entrained with the biofilm matrix, the decomposition or programmed disintegration of the liposome proceeds. Thereafter, the biocidal aqueous core is released to react directly with the biofilm encased microorganisms.

  • Publication number: 20090191247
    Abstract: This invention generally relates to use of novel nanomaterials comprised of metals in anti-viral applications. Such nanomaterials, for example, can be produced using a high power, pulsed plasma process, which plasma process, optionally, can be performed on the metal with a precursor (i.e., a gaseous precursor, such as acetylene or methane) when forming the unagglomerated nanomaterials. In embodiments of the invention, the metal is nanosilver. Optionally, the nanomaterials may also comprise carbon, including in the form of carbyne.
