20090326659 | HIGH MODULUS CROSSLINKED POLYETHYLENE WITH REDUCED RESIDUAL FREE RADICAL CONCENTRATION PREPARED BELOW THE MELT - The present invention provides an irradiated crosslinked polyethylene containing reduced free radicals, preferably containing substantially no residual free radical. Disclosed is a process of making irradiated crosslinked polyethylene by irradiating the polyethylene in contact with a sensitizing environment at an elevated temperature that is below the melting point, in order to reduce the concentration of residual free radicals to an undetectable level. A process of making irradiated crosslinked polyethylene composition having reduced free radical content, preferably containing substantially no residual free radicals, by mechanically deforming the polyethylene at a temperature that is below the melting point of the polyethylene, optionally in a sensitizing environment, is also disclosed herein. | 12-31-2009 |

20120160362 | ARTICLES AND METHODS FOR REDUCING HYDRATE ADHESION - This invention relates generally to articles, devices, and methods for gas hydrate mitigation in deep-sea drilling applications. In certain embodiments, hydrate-phobic surfaces are provided that ensure passive enhancement of flow assurance and prevention of catastrophic failures in deep-sea oil and gas operations. | 06-28-2012 |
20130025322 | PROCESS FOR MAKING NANOCONE STRUCTURES AND USING THE STRUCTURES TO MANUFACTURE NANOSTRUCTURED GLASS - Fabrication method. At least first and second hardmasks are deposited on a substrate, the thickness and materials of the first and second hardmask selected to provided etch selectivity with respect to the substrate. A nanoscale pattern of photoresist is created on the first hardmask and the hardmask is etched through to create the nanoscale pattern on a second hardmask. The second hardmask is etched through to create the desired taper nanocone structures in the substrate. Reactive ion etching is preferred. A glass manufacturing process using a roller imprint module is also disclosed. | 01-31-2013 |
20130178568 | LIQUID REPELLENT SURFACES - A surface can be coated with a liquid repellent coating. Materials for making the liquid repellent coating (e.g., a fingerprint resistant coating) can be selected on the basis of surface energy considerations, such as a receding surface energy. The materials can include a polymer and a liquid repelling material, for example, poly(ethyl methacrylate) and a fluorinated silsesquioxane such as fluorodecyl POSS. | 07-11-2013 |
20140190352 | LIQUID COLLECTING PERMEABLE STRUCTURES - A structure for collecting liquid droplets from an aerosol can have a structure and properties that are selected for efficient liquid collection. In particular, the strand radius and spacing of a mesh, and a material for coating the mesh, can be selected to provide efficient collection of water droplets from fog. | 07-10-2014 |
20140336039 | ANTI-FINGERPRINT PHOTOCATALYTIC NANOSTRUCTURE FOR TRANSPARENT SURFACES - Titania-based porous nanoparticle coatings are mechanically robust, with low haze, which exhibit short time scales for decomposition of fingerprint oils under ultraviolet light. The mechanism by which a typical dactylogram is consumed combines wicking of the sebum into the nanoporous titania structure followed by photocatalytic degradation. These TiO | 11-13-2014 |
