  • Patent number: 8029887
    Abstract: An optical article, having an almost complete isotropy and dimensions equal to or lower than 500 .mu.m, is prepared by a sol-gel procedure comprising a preliminary step wherein the mould is filled cold with a sol containing the desired oxide precursors, sol gelation, gel drying, removal of the gel from the mould and the subsequent miniaturization of the dried gel. The optical article can be used for optic telecommunications.

  • Publication number: 20090215606
    Abstract: Sol-gel process comprising preparation of a solution of at least one compound having the formula Xm-M-(OR)n-m addition to the solution of the dopants, hydrolysis of the compound to form the sol, possible addition of an oxide, gelling the sol, recycling the liquid and adjusting the pH-value of the liquid in order to fix the dopants in the aquagel, gel drying and densifying to obtain the glass.

  • Publication number: 20080237904
    Abstract: An optical article, having an almost complete isotropy and dimensions equal to or lower than 500 ?m, is prepared in which the sol-gel procedure comprises a preliminar step wherein the mould is cool filled with a sol containing the interesting oxide precursors, the sol gelation, the gel drying, the removal of gel from the mould and the final miniaturization of the dried gel. The optical article can be used for optic telecommunications.

  • Publication number: 20080098771
    Abstract: An improved sol-gel process is disclosed for the making of large synthetic silica based bioactive materials objects crack-free. A series of ordered mesoporous SiO2—CaO—P2O5 sol-gel glasses which are highly bioactive are synthesized through a sol-gel process. The mesoporous glasses are highly bioactive compared with conventional ones, due to the increased textural characteristics, i.e. surface area. The bioactivity tests point out that the surface area, porosity, and 3D-structure become more important than chemical composition during the apatite crystallization stage in these materials, due to the very high textural parameters obtained. The product is intended to be used for tissue engineering applications.

  • Publication number: 20070141359
    Abstract: The present invention relates to glassy inorganic films, characterized by a high chemical stability and a high adhesion, containing, among the others, titanium dioxide, employable to coat metal surfaces characterized by the presence of oxides, particularly stainless steel sheets. The coated structures obtained thereby, which are the second object of the present invention, are used to build many articles such as pipes, reactors, exchangers, containers, and so on. With reference to the peculiar case of stainless steel structures coated by the above film, these ones can be used in the food industry since that film coated article shows specific and very high photobactericide properties.
