    摘要： The present invention discloses an artificial nerve graft prepared by electrostatic spinning, the preparing method and a special apparatus used therefor. Said artificial nerve graft is in the shape of a tube composed of nano-fiber that is prepared by electrostatic spinning of a polymer. The materials used in the present invention are bio-degradable materials and of desirable biocompatibility with human body. The product of the present invention is free of exogenous toxic substances or substances having side effects. Furthermore, the tube wall is of a 3-dimensional structure having micropores contained therein thereby providing a path for supplying nutritions required for the growth of nerve cells. Another advantage of the present invention is that necessary induction and space are provided for the growth of the nerve cells.

    摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for fabricating parts from photopolymer resin. In one aspect, a method includes iteratively determining a deviation measurement based on a simulated cured geometry and adjusted target geometry data until the deviation measurement is at or less than a threshold. The simulated cured geometry is determined, based in part, on an inhibition model.

    摘要： The present inventions is related to the optical lenses that use subwavelength structures to perform an optical function, the applications of such lenses, and the methods of making the same. Particularly, the present invention provide an optical lens(es), termed “subwavelength Moiré index lens” or “SMIL” for manipulating light. The SMIL comprises a thin material layer having an effective optical index that has a Moiré pattern of two or more periodic structures. The SMIL allows a lens to be ultrathin, flat, numerical aperture nearly one, scalable to large area, and manufacturable at low cost. The present invention also provides the systems based on SMIL, such lens systems, LEDs and photodetectors, and the fabrication methods of the SMIL.

    摘要： Electrodeposition and energy storage devices utilizing an electrolyte having a surface-smoothing additive can result in self-healing, instead of self-amplification, of initial protuberant tips that give rise to roughness and/or dendrite formation on the substrate and anode surface. For electrodeposition of a first metal (M1) on a substrate or anode from one or more cations of M1 in an electrolyte solution, the electrolyte solution is characterized by a surface-smoothing additive containing cations of a second metal (M2), wherein cations of M2 have an effective electrochemical reduction potential in the solution lower than that of the cations of M1.
