Abstract:
A method of producing a glass briquette in which reclaimed glass fines are mixed with a binder material to create a mixture. The mixture is subsequently compressed in a chamber to form a briquette having the shape of the interior of the chamber. The reclaimed glass includes glass fines of a size of smaller than 10 mm. The method is performed without melting the glass fines such that the resulting briquette contains the discrete glass fines held in the binder and may be used as a furnace ingredient for later glass product production. The glass briquette may contain other batch ingredients required in the production of glass.
Abstract:
The present invention relates to silica materials and particles having surfaces which define an interior. The interior includes interior silicon atoms at least a portion of which is bonded to a substituted or unsubstituted alkyl moiety. In a preferred aspect of the present invention, the silica material also has surface silicon atoms to which are bonded substituted or unsubstituted alkyl moieties. A capillary tube coated on its inner surface with the silica material of the present invention is also disclosed. The silica materials of the present invention are resistant to degradation at high or low pH and are particularly useful as chromatographic stationary phases, especially for use in open tubular liquid chromatography and open tubular electrochromatography.

Abstract:
The present disclosure provides a method to fabricate three-dimensional transparent glass utilizing polymer plasticity, including the following steps. In step 1, synthesize polymer-glass powder composite containing dynamic chemical bonds, the bond exchange catalyst is added during the synthesis process, and then cure to obtain a two-dimensional sheet shape I, the bond exchange catalyst is used to activate a dynamic chemical bond in step 2. In step 2, shape the two-dimensional sheet shape I obtained in step 1 into a complex three-dimensional shape II under the conditions of the effect of an external force and the activable dynamic chemical bond. In step 3, pyrolyze the composite precursor at high temperature to obtain transparent glass with complex three-dimensional shape II. The present disclosure provides a method in shaping the transparent glass with complex geometries by unique polymer plasticity in lower temperature.

Abstract:
The present invention relates to increasing the photosensitivity of optical fibers. One aspect of the present invention comprises a method for rapidly diffusing hydrogen or deuterium into an optical fiber from a gas mixture having a low total hydrogen content to generate changes in the refractive index of the optical fiber. The resulting photosensitive fiber may be used to create optical devices including Bragg gratings and Bragg grating-based devices.
