摘要： A mesoporous, transition metal oxide material having an average pore diameter ranging from 2 to 20 nm, a basic surface character defined by an isoelectric point>pH 7, and a specific surface area greater than 50 m2/g can be incorporated into a NOx sensing device as a NOx film. The mesoporous, transition metal oxide material includes an oxide of yttrium, lanthanum and/or cerium, and can be formed using a surfactant-templated self-assembly process.

摘要： Methods for forming optical fiber preforms with low-index trenches are disclosed. According to one embodiment, the method includes depositing silica-based glass soot on a bait rod to form a low-index trench region of the optical fiber preform. The silica-based glass soot is deposited such that the low-index trench region has a first density. Thereafter a barrier layer having a second density greater than the first density is formed around the low-index trench region. Therafter, an overclad region is deposited around the barrier layer. The bait rod is then removed from a central channel of the trench-overclad assembly. A separate core assembly is inserted into the central channel. A down-dopant gas is then directed through the central channel of the trench-overclad assembly as the trench-overclad assembly is heated to dope the low-index trench region. The barrier layer prevents diffusion of the down-dopant from the low-index trench region into the overclad region.

摘要： The disclosure relates to methods of forming a vessel and to the resulting vessel. The vessel may be formed by providing a first fumed silica soot layer comprised of primary particles of fumed silica soot, and then providing over the first fumed silica soot layer a second fumed silica soot layer comprised of agglomerated particles formed into an agglomerated form from primary particles of fumed silica soot. The primary particles of the first fumed silica soot layer may have a substantially uniform density distribution, and the agglomerated particles of the second fumed silica soot layer may have a substantially non-uniform density distribution. The methods may include consolidating the first and second soot layers together to form a consolidated body.

摘要： A method of forming a cladding portion of an optical fiber preform assembly includes positioning a glass core cane in a mold cavity and loading the mold cavity with silica glass soot. The silica glass soot is compressed in an axial direction as the vibratory energy is applied to the mold body to form a soot compact around the glass core cane, wherein the soot compact is the cladding portion of an optical fiber preform assembly and the glass core cane is a core portion of the optical fiber preform assembly.
