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, solidifying the liquid feedstock within the channels, and then locally melting and directionally re-solidifying the feedstock.
Abstract:
The invention relates to methods of making articles of semiconducting material and semiconducting material articles formed thereby, such as articles of semiconducting material that may be useful in making photovoltaic cells.

Abstract:
A substrate having a durable hydrophobic and/or oleophobic surface. The durable hydrophobic and/or oleophobic surface includes a first layer that is disposed on the substrate and comprises inorganic nanoparticles, an outer layer comprising a fluorosilane, and an optional immobilizing layer that comprises at least one of an inorganic oxide and a silsesquioxane. The durable surface is capable of retaining optical properties, such as haze, and hydrophobic and/or oleophobic properties after repeated contact with foreign objects such as, for example, wiping with a cloth or human finger.
Abstract:
A method of treating a sheet of semiconducting material comprises forming a sinterable first layer over each major surface of a sheet of semiconducting material, forming a second layer over each of the first layers to form a particle-coated semiconductor sheet, placing the particle-coated sheet between end members, heating the particle-coated sheet to a temperature effective to at least partially sinter the first layer and at least partially melt the semiconducting material, and cooling the particle-coated sheet to solidify the semiconducting material and form a treated sheet of semiconducting material.
Abstract:
Methods for making and/or treating articles of semiconducting material are disclosed. In various methods, a first article of semiconducting material is provided, the first article of semiconducting material is heated sufficiently to melt the semiconducting material, and the melted semiconducting material is solidified in a direction substantially parallel to a shortest dimension of the melted article of semiconducting material. Articles of semiconducting materials made by methods described herein are also disclosed.
Abstract:
A method of making an article of a semiconducting material involves withdrawing from a melt of molten semiconducting material a solid mold having already formed on an external surface of the mold a solid layer of the semiconducting material. During the act of withdrawal, one or more of a temperature, a force, and a relative rate of withdrawal are controlled in order to achieve one or more desired attributes in a solid overlayer of semiconductor material that is formed over the solid layer during the withdrawal.

Abstract:
A glass substrate having at least one surface with engineered properties that include hydrophobicity, oleophobicity, anti-stick or adherence of particulate or liquid matter, resistance to fingerprinting, durability, and transparency (i.e., haze
Abstract:
Feed materials are melted in a furnace to form a glass melt at a first temperature T1, the glass melt containing at least one fining agent. The glass melt is cooled to a second temperature T2 less than T1, and an oxygen-containing gas is bubbled through the cooled melt. The glass melt is then re-heated to a third temperature T3 equal to or greater than the first temperature T1.
