Abstract:
A sol-gel method for forming durable, scratch-resistant coatings on glass substrates. Zirconia coatings, for example, are formed from a solution of zirconium oxychloride octahydrate in an organic, polar, aprotic solvent such as dimethylformamide. Annealed coatings, which optionally include an additive such as graphene, have a low coefficient of friction and can exhibit high hardness and hydrophobicity.
Abstract:
Silicon-silica hybrid materials made by metallothermal reduction from silica and methods of producing such compositions are provided. The compositions have novel properties and provide significant improvements in Coulombic efficiency, dilithiation capacity, and cycle life when used as anode materials in lithium battery cells.
Abstract:
A crystallized layer can be formed on a substrate from a precursor layer deposited on a surface of the substrate. The precursor layer can be an oxide, a nitride, a carbide, or an oxynitride. The process for forming the crystallized layer includes melting the precursor layer formed on the surface of the substrate by localized topical heating of the precursor layer and then cooling the melted precursor layer so that it crystallized to form a scratch resistant crystallized layer. The scratch resistant crystallized layer can have a hardness of 15 GPa or greater.
Abstract:
Laminated glass-based articles are provided. The glass-based articles include at least a first glass-based layer, a second glass-based layer, and a polymer layer disposed between the first and second glass-based layers. The first glass-based layer includes a compressive stress. A difference between the coefficient of thermal of expansion of the first glass-based layer and the coefficient of thermal of expansion of the second glass-based layer is greater than or equal to 0.4 ppm/° C. Methods of producing the laminated glass-based articles are also provided.
Abstract:
A method of forming a liquid lens, comprising the steps of: positioning a first substrate defining a hole over a second substrate, wherein a cavity is defined within the second substrate and aligned with the hole; dispensing a second liquid into the cavity defined within the second substrate; capping the second liquid with a first liquid dispensed through the hole, wherein the first liquid and the second liquid have different refractive indices than each other; and translating at least one of the first substrate and the second substrate such that the hole is not aligned with the cavity.
Abstract:
A perfusion bioreactor and a method for using the perfusion bioreactor for performing a continuous cell culture are disclosed. The perfusion bioreactor includes an outer vessel having a housing with a gas permeable membrane, an opening and a cavity; an inner vessel within the cavity; and a lid to cover the opening. A porous membrane within the cavity divides the cavity into inner and outer compartments. A fresh media port extends through the outer vessel or the at least one lid to receive a fresh media tube that has an end located in the inner compartment. A spent media port extends through the outer vessel or the at least one lid to receive a spent media tube that has an end located in the outer compartment. A mixer is within the inner compartment, and the porous membrane is attached to an opening within the inner vessel.

Abstract:
An electrode coating composition that includes at least one crosslinkable monomer; at least one hydrophobic monomer; and at least one dielectric constant enhancing agent selected from dielectric enhancing monomers, ferroelectric particulates, and electroactive polymers. Coatings including the polymer of compositions, and articles including electrically isolating layers are also disclosed.
