Abstract: The present invention relates to synthetic resin composition containing nano silver particles, in which a silver complex having a specific structure that allows formation of the nano silver particles is dissolved in monomer for the resin composition and the organic silver complex is decomposed with polymerization to prepare the synthetic resin composition containing the nano silver particles. The present invention can provide a method for resin compositions, which has simple and economic preparation process and allows uniform dispersion of the nano silver particles in the resin composition.

Abstract: The invention is directed to a solid, porous material, suitable for generating nitrogen gas, said material having a porosity of 20 to 75 vol. %, and a composition comprising, based on the weight of the material of 60 to 90 wt. % of sodium azide, 0.1 to 20 wt. % of an inert chemical coolant based on at least one inorganic salt having a heat capacity of at least 1400 J/K/kg, 0.1 to 20 wt. % of modifying agent selected from metal oxides and metal carbonates, and a binder, selected from the group consisting of at least one alkali metal silicate, preferably waterglass, or a poly-tetrazole, in an amount of between 3 and 15 wt. %.

Abstract: The invention is a method and composition for producing carbon dioxide that is based on the reaction or activation of at least one carbon-containing compound with protons. The carbon-containing compound can be in the form of a powder, an impregnated carrier (e.g. zeolite crystals) or an aqueous solution and is preferably selected from the group consisting of carbonates, bicarbonates or sesquicarbonates. The protons are preferably provided by a proton-generating species such as an acid or metal salt. The method and composition can further include a water-retaining substance and/or a chlorine dioxide-producing compound in accordance with the invention.

Abstract: The invention comprises a gastric device having a pouch formed from a degradable film. Preferably, the pouch contains a gas producing material. The gastric device hydrates within a patient's stomach and the gas producing material expands the device to a greater volume. Accordingly, the volume of the hydrated, expanded gastric devices occupy space in the stomach cavity and reduce the amount of food the patient will ingest before reaching the feeling of fullness. Preferably, the gastric device is made from food grade materials. The gastric device is configured to expand to a desired volume and then degrade after a residence time, allowing the device to be passed by the patient's normal digestive process.

Abstract: A material mixture is disclosed for storage of hydrogen for a hydrogen-using device and release of hydrogen on demand of the hydrogen-using device, especially by heating of the mixture. Such a mixture suitably comprises a solid hydrogen-containing lithium compound (e.g. LiBH4) and a solid magnesium compound, MgX, the magnesium compound being reactive with the lithium compound to release hydrogen and yield solid by products containing lithium and X. X may include one or more of F, Cl, OH, O, S, Se, Si, CO3, SO4, Cu, Ge, Ni, (OH)Cl, and P2O7.

Abstract: The invention comprises a gastric device having an outer region and a gas producing material. The gastric device hydrates within a patient's stomach and the gas producing material expands the device to a greater volume. Accordingly, the volume of the hydrated, expanded gastric devices occupy space in the stomach cavity and reduce the amount of food the patient will ingest before reaching the feeling of fullness. Preferably, the gastric device is made from food grade materials. The gastric device is configured to expand to a desired volume and then degrade after a residence time, allowing the device to be passed by the patient's normal digestive process.
