Abstract:
A space filled drug release structure and a method of manufacturing the same are disclosed. The structure is composed of a highly water-absorbing polymeric matrix and drug particles dispersed in the matrix. The matrix has pores and passages interconnecting the pores together. Because some water is present in the matrix, gastric acid can easily penetrate into the matrix to reach each drug particle. The surface of each drug particle is therefore possible to contact with the gastric acid. The drug releasing rate is therefore fast. Such structure is helpful for those drugs with low dissolution ability in the gastric acid.
Abstract:
A platinum-free and palladium-free conductive adhesive includes silver particles, additive metal particles and a binder. Components of the additive metal particles are selected from the group consisting of tungsten, niobium, tantalum and molybdenum etc., and do not contain platinum and palladium. The binder adheres the silver particles and the additive metal particles together. A specific weight percentage of the additive metal particles in a mixture of the silver particles and the additive metal particles ranges from 1 to 70. The presence of the additive metal particles can suppress silver migration. An electrode formed by the conductive adhesive is also disclosed.
Abstract:
A sintered calcium sulfate ceramic material includes a plurality of major grains of calcium sulfate solid solutions, and a plurality of reaction grains located at boundaries of the major grains. Each of the reaction grains may be selected from the group consisting of calcium silicate and calcium phosphate. A. sinterable calcium sulfate ceramic material consisting of calcium sulfate and a sintering additive is also provided. The sintering additive comprises silica (SiO2).
Abstract:
The present invention discloses a method that can improve the sintering ability of calcium sulfate. The material can be used as a bio-material. This method is prepared by pre-mixing +1 and/or +2 and/or +3 and/or +4 and/or +5 valence element and/or its chemical compounds which serves as a sintering additive to calcium sulfate. During sintering, the sintering additive may form a compound and/or a glass and/or a glass-ceramic to assist the densification of the calcium sulfate. The strength and biocompatibility of the specimen after sintering are satisfactory.
Abstract:
A mobile phone with a stepless motion function is provided and includes a mobile phone body, an upper cover which can be movably provided outside the mobile phone body, and a pushing device including a first end part and a second end part, wherein the first end part is fixedly provided at the upper cover, and the second end part is fixedly provided at the mobile phone body, whereby the upper cover can move at a constant velocity from a first position to a second position relatively to the mobile phone body. Therefore, the mobile phone with a stepless motion function of the invention enables the upper cover to move at a constant velocity at the mobile phone body to increase the tactile sensation of the mobile phone.
