  • Patent number: 9217130
    Abstract: Disclosed is a method of producing a cell culture vessel (10) having a carbon nanotube (CNT) layer (14) on its surface. The method comprises the steps of providing a vessel (12) having a predetermined shape; providing a CNT dispersion of a CNT material composed primarily of CNT dispersed in a dispersion medium at a concentration of not more than 50 mg/L; and forming the carbon nanotube layer (14) on the surface of the vessel (12). The formation of the CNT layer (14) is achieved by alternately repeating a supply step of applying the CNT dispersion solution to the vessel (12) and a drying step of drying the applied dispersion solution one or more times.

  • Patent number: 5759029
    Abstract: An esthetic orthodontic wire comprising a composite material which includes a biocompatible inorganic fiber and a thermoplastic resin. The inorganic fiber is glass fiber formed linearly continuous and having a generally circular or oval cross-sectional shape. The inorganic fiber has a diameter ranging from 1 to 100 .mu.m. The biocompatible inorganic fiber is produced from a mixture of calcium oxide, diphosphorus pentoxide, silicon dioxide and aluminium oxide. The inorganic fiber is biocompatible, in which a molar ratio of calcium/phosphorus is within a range of from 0.5 to 3.0, wherein total of calcium oxide and diphosphorus pentoxide is within a range of from 20 to 65% by weight relative to the glass fiber, and total of silicon dioxide and aluminium oxide is within a range of from 35 to 80% by weight relative to the glass fiber. The content of the glass fiber is within a range of from 5 to 70% by volume of the orthodontic wire.
