Abstract: A three-dimensional (3D) electrode architecture for a microbattery includes an anode structure comprising one or more anode digits and a cathode structure comprising one or more cathode digits, the anode digits being positioned alternately with the cathode digits in an interdigitated configuration on a substrate, where each of the anode digits has a width wa and each of the cathode digits has a width wc. Each of the anode digits comprises an anode material deposited on a first current collector and extending to a height h above the first current collector, and each of the cathode digits comprises a cathode material deposited on a second current collector and extending to a height h, above the second current collector. A height-to-width aspect ratio ha/wa of the anode structure and a height-to-width aspect ratio hc/wc of the cathode structure are at least about 2.

Abstract: Stabilized silver particles comprise particles comprising silver, a short-chain capping agent adsorbed on the particles, and a long-chain capping agent adsorbed on the particles. The short-chain capping agent is a first anionic polyelectrolyte having a molecular weight (Mw) of at most 10,000, and the long-chain capping agent is a second anionic polyelectrolyte having a molecular weight (Mw) of at least 25,000. The stabilized silver particles have a solid loading of metallic silver of at least 50 wt %.

Abstract: The present invention is related to a process of manufacturing rutile high-purity titania nano sols in a pure aqueous medium having no ionic impurities. In more detail, the present invention is related to a process for manufacturing titania nano sols, in which high-purity rutile titania nano particles are dispersed stably, through the hydrolysis of titanium tetraisopropoxide in an aqueous solution containing hydrogen peroxide (H2O2), and simultaneously with the hydrolysis, formation of peroxotitanate precursors, and hydrothermal treatment of them at 50-120° C.

Abstract: The present invention relates to a process for preparing silica microcapsules and more particularly, to a process for preparing silica microcapsules comprising the steps of dissolving tetraethyl orthosilicate (TEOS) into an aqueous solution containing a hydrolysis catalyst to control a degree of hydrolysis and contribute hydrophilicity or lipophilicity, adding a core material and an appropriate amount of aminopropyltrialkoxysilane(APS) as a gelling agent into the solution, and emulsifying and dispersing the resulting solution to a solution having a polarity opposite to that of the core material to microcapsulate by coating the core material with silica shell via a sol-gel reaction. The process for preparing microcapsules of the present invention reduces environmental pollution compared to conventional processes using an alkali gelling agent such as an ammonia solution, and are suitable for both organic or inorganic core materials having hydrophilic or lipophilic property.
