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: Cellular ceramic articles are manufactured from a green cellular ceramic body that includes a binder material and a plurality of channels. At least one of the channels is coated with a slurry that includes a green coating composition and a solvent to form a coating layer. The binder material is insoluble in the solvent.

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<10%). The surface comprises at least one set of topological features that together have a re-entrant geometry that prevents a decrease in contact angle and pinning of drops comprising at least one of water and sebaceous oils.

Abstract: A process for creating hydrophobic and oleophobic glass surfaces. The process consists of heating a glass article to temperatures near the glass softening point and pressing a textured mold into the glass article to create surface texture. The mold texture is selected to have dimensions that convey hydrophobicity and oleophobicity to the glass article when combined with appropriate surface chemistry. The surface features are controlled through choice of mold texture and through process parameters including applied pressure, temperature, and pressing time. Articles made by this process are also described.

Abstract: A thin film battery comprises a substrate, anode and cathode current collector layers formed over the substrate, anode and cathode layers formed over and in electrical contact with respective ones of the current collector layers, and an electrolyte layer formed between the anode and cathode layers. The thin film battery further comprises a barrier layer formed from a material such as tin oxide, tin phosphate, tin fluorophosphate, chalcogenide glass, tellurite glass or borate glass. The barrier layer is configured to encapsulate the thin film battery layers and substantially inhibit or prevent exposure of the thin film battery layers to air or moisture.

Abstract: We present a method for informed optimization of sampling vectors in multi-directional diffusion-weighted magnetic resonance imaging. The advantage of this optimization is that it is informed rather than being a naïve optimization of sampling vectors. Typically, sampling vectors are set relatively uniformly along a spherical surface. In this case, a scan at high imaging resolutions utilizes sampling vectors that are chosen based on the knowledge of the overall orientation distribution for the entire sample or region of interest. This overall orientation distribution is obtained by performing multi-directional diffusion-weighted scans at high angular resolution, but low or minimal voxel resolution. A subset of the vectors used in this high-angular-resolution scan is chosen to minimize the error in the final results. This optimal subset is not necessarily uniform in space.
