Abstract:
A templated mold comprises a mold body formed from a mold material. The mold body has at least one major surface with a patterned layer formed from a patterning material disposed over the major surface. The patterned layer defines a high nucleation energy barrier surface and a plurality of nucleation surfaces, such that a contact angle of a molten semiconducting material with the nucleation surfaces is less than a contact angle of the molten semiconducting material with the high nucleation energy barrier surface, and the nucleation surfaces are formed from either the mold material or the patterning material.

Abstract:
A method of forming a templated casting involves incorporating a liquid feedstock into the channels of a honeycomb substrate to form a feedstock-laden substrate, and directionally solidifying the liquid feedstock within the channels.

Abstract:
Composite carbon electrodes for use in, for example, Capacitive Deionization (CDI) of a fluid stream or, for example, an electric double layer capacitor (EDLC) are described. Methods of making the composite carbon electrodes are also described. The composite carbon electrode comprises an electrically conductive porous matrix comprising carbon; and an electric double layer capacitor, comprising an activated carbonized material, dispersed throughout the pore volume of the electrically conductive porous matrix.
Abstract:
The invention includes methods and apparatus for depositing soot onto a glass surface to minimize water in the deposited soot and the diffusion of the water into the glass surface. The invention includes depositing a first layer of soot a on the glass surface at a first forward traverse rate and depositing a second layer of soot at a second forward traverse rate.
Abstract:
A method and apparatus for forming a glass article such as an optical fiber having a substantially matching viscosity across an interface associated with a first section and a second section of the optical fiber is disclosed herein. The first section has a first halogen concentration and the second section has a second halogen concentration. At least one of a partial pressure of the second halogen provided to a substrate tube and a temperature of the substrate tube is configured to affect the concentration of the second halogen in the second section. Optical fiber embodiments are also included.
Abstract:
A glass substrate having an oleophobic surface. The surface is substantially free of features that form a reentrant geometry and includes a plurality of gas-trapping features extending from the surface to a depth below the surface and a coating comprising at least one of a fluoropolymer and a fluorosilane. The gas-trapping features are substantially isolated from each other, and trap gas below droplets to prevent wetting of the surface.
