Abstract: A family of glasses from the rare earth alumino-silicate (RE2O3-Al2O3-SiO2) ternary system exhibiting high strain point and low liquidus temperatures; preferably the La2O3 -Al2O3-SiO2 ternary system. The glasses are excellent candidates for electronics applications and have the following composition, expressed in mole percent and calculated from the glass batch on an oxide basis: 60-85% SiO2, 10-25% Al2O3, and 4-15% RE2O3.

Abstract: The invention is directed to hermetically sealed optical lithography components or elements that are hermetically sealed by a durable coat of a hermetically sealing material selected from the group consisting of oxide and fluorinated oxide films. The durable coating of the hermetically sealing material is applied to one of more faces of the optical element, either directly to the face of the element or over a selected coating (for example, an anti-reflective coating) that has been applied to the element. The invention is further directed to a method of making hermetically sealed optical elements.

According to one embodiment of the invention, a semiconductor-on-insulator structure has a first layer including a semiconductor material, attached to a second layer including a glass or glass-ceramic, with the CTEs of the semiconductor and glass or glass-ceramic selected such that the first layer is under tensile strain. The present invention also relates to methods for making strained semiconductor-on-insulator layers.

Abstract: Glass-ceramic materials are fabricated by infiltrating a porous glass matrix with a precursor for the crystalline phase, drying, chemically reacting the precursor, and firing to produce a consolidated glass-ceramic material. The pore size of the glass matrix constrains the growth and distribution of nanocrystallite size structures. The precursor infiltrates the porous glass matrix as an aqueous solution, organic solvent solution, or molten salt. Chemical reaction steps may include decomposition of salts and reduction or oxidation reactions. Glass-ceramics produced using Fe-containing dopants exhibit properties of magnetism, low Fe2+ concentrations, optical transparency in the near-infrared spectrum, and low scattering losses. Increased surface area permits expanded catalytic activity.

Abstract: A microfluidic reactor (10) for trapping one or more particles of predetermined nominal size or range of sizes that have entered a flow inlet (12) includes a transparent reaction zone (14) which also serves as an in-situ detection zone wherein the detection zone is arranged so as substantially to correspond in shape to an optical detector (456). A porous filter (16) having a plurality of holes (160) being smaller than the nominal size or range of sizes of the particles (200) are arranged so as to trap the particles in the reaction zone (14) while a fluid (18) flows from the flow inlet (12) through the reaction zone (14) and the filter (16).
