摘要:
A sanitary article is provided that includes a dried polymeric matrix with embedded enzyme. The presence of the enzyme in the polymeric matrix allows the sanitary article to absorb a bodily discharge fluid thereby allowing the embedded enzyme to function in the production of antibacterial compounds or by directly reducing the presence of viable bacteria in the discharge fluid. The enzyme activity promotes reduced odor in the sanitary article.

A multilayer photonic structure may include a plurality of coating layers of high index dielectric material of index of refraction nH and a plurality of coating layers of low index dielectric material of index of refraction nL alternately arranged with a first coating layer and a last coating layer of the multi-layer photonic structure comprise low index material. An index-thickness of each coating layer of the multilayer photonic structure is different than every other coating layer of the multilayer photonic structure. The multilayer photonic structure has a first high reflectivity bandwidth, a second high reflectivity bandwidth and a low reflectivity bandwidth wherein the low reflectivity bandwidth is positioned between the first high reflectivity bandwidth and the second high reflectivity bandwidth.

A bioactive composition includes a hydrogel matrix. At least one protein is immobilized in the hydrogel matrix. The digestive protein has a half-life at least 1000 times longer than the half-life of a free digestive protein counterpart.
摘要:
A process for manufacturing stand-alone thin films is provided. The process includes providing a substrate, depositing a carbon-containing sacrificial layer onto the substrate and the depositing a thin film onto the carbon-containing sacrificial layer. Thereafter, the substrate, carbon-containing sacrificial layer and thin film structure are exposed to oxygen at an elevated temperature. The oxygen reacts with the carbon-containing sacrificial layer to produce carbon dioxide and remove carbon from the sacrificial layer, thereby generally burning away the sacrificial layer and affording for an intact stand-alone thin film to separate from the substrate.

A thermoelectric material comprises core-shell particles having a core formed from a core material and a shell formed from a shell material. In representative examples, the shell material is a material showing an appreciable thermoelectric effect in bulk. The core material preferably has a lower thermal conductivity than the shell material. In representative examples, the core material is an inorganic oxide such as silica or alumina, and the shell material is a chalcogenide semiconductor such as a telluride, for example bismuth telluride. A thermoelectric material including such core-shell particles may have an improved thermoelectric figure of merit compared with a bulk sample of the shell material alone. Embodiments of the invention further include thermoelectric devices using such thermoelectric materials, and preparation techniques. The use of core-shell nanoparticles allows highly uniform nanocomposites to be formed, and embodiments of the invention also includes other materials and devices using core-shell particles.
