20130186968 | Welding Structure with Double-Inclined Surface of No Bumping and No Vibration Seamless Rail with High Load-Bearing Capability - A double inclined weld face structure for a jolt-and-vibration-free seamless rail with high bearing capacity relates to the welding of the seamless rail of the rail train, a weld seam of the rail according to the present application forms, at least partly, a double inclined weld face, forming an angle α with the vertical direction of the rail and an angle β with the transverse direction of the rail. The double inclined weld face can further improve the stress state in the weld face of the rail, enhance the bearing capacity of the weld face and eliminate upward and downward jolting and leftward and rightward shaking of a train. The double inclined weld faces of the two parallel rails ( | 07-25-2013 |
20130164881 | METHOD FOR PRODUCING FULLY AQUEOUS PHASE-SYNTHESIZED NANOCRYSTALS/CONDUCTING POLYMER HYRID SOLAR CELL - Provided is a method for producing a highly efficient organic/inorganic hybrid solar cell using fully aqueous phase-synthesized semiconductor nanocrystals and conducting polymer. The method mainly includes three steps: synthesizing nanocrystals in an aqueous phase, synthesizing a conjugated polymer precursor in an aqueous phase, and producing a device of solar cell. The nanocrystal material required for producing a solar cell by the method is widely available, diversified and size-controlled, and the used conjugated polymer has regulated molecular structure and molecular weight, which contributes to increase the absorption of sunlight. The processing of cell device can be performed at room temperature in air, and has advantages of no pollution, short processing period, and low cost. A method for producing an organic/inorganic hybrid solar cell is developed, which succeeds in introducing the high quality nanocrystals synthesized in an aqueous phase and is an eco-friendly and pollution-free technology for producing a solar cell. | 06-27-2013 |
20120252121 | Culture Method for Amplifying Large Numbers of Hair Follicle Stem Cells in Vitro - The present invention is a method, belonging to the field of cell culture, for amplifying a large numbers of hair follicle stem cells in vitro by using microspheres as carriers for cell culture and a revolving bottle as a fermentation tank for cell proliferation. The method is simple in its procedures, is economical and practical, and avoids side effects associated with the traditional cell amplification method, such as the weakening of cell proliferation capability, the reduction of differentiation potential and the like caused by repeated cell subculture, and also reduces the consumption of the culture solution; the hair follicle stem cells amplified by the method can still keep the original proliferation capability and differentiation potential, and can be used for: (1) establishing hair follicle stem cell bank to provide high-quality seed cells for related research on adult stem cells; (2) transplanting and repairing tissues and organs subjected to pathological changes; (3) constructing tissue-engineered organs to be used as substitute autologous organs for transplantation or repair of organs subjected to pathological changes or missing organs; and (4) serving as target cells for the genetic treatment of corresponding diseases. | 10-04-2012 |
