  • Publication number: 20240190712
    Abstract: The invention provides a nano-silicon agglomerate composite negative electrode material of pine needle and branch-shaped three-dimensional network structure and a method for preparing the same. The nano-silicon agglomerate composite negative electrode material comprises nano-sized core particles, a nano-silicon agglomerate of pine needle and branch-shaped three-dimensional network structure growing around the nano-sized core particles, and a composite coating layer over the nano-silicon agglomerate of needles and branch-shaped three-dimensional network structure. With measurements, it is shown that the nano-silicon agglomerate composite negative electrode material, when being applied in lithium ion battery, has excellent battery charge-discharge cycle performances and rate capability, and it has an initial discharge capacity per gram of more than 2600 mAh/g, and an initial coulombic efficiency of no less than 85%.

  • Publication number: 20030035755
    Abstract: Organic electroluminescent (OEL) devices are proposed herein to be fabricated either as a light source or a heating source for biochips. Under the proposed approach, an OEL-emitting member is fabricated as the substrate of the biochip on which the biological samples, such as DNA, proteins and other related small molecules, are processed for the desired applications, including but not limited to, analysis of biological molecules, such as electrophoretic separation, PCR amplification and hybridization.

  • Patent number: 6316056
    Abstract: A method for producing isolation copper facing membranes, in which the basic material is the “polyimide” isolation membrane “KAPTON”, includes the steps of: cleaning the “polyimide” isolation membrane “KAPTON” using a high pressure air stream to remove dust from the board; placing the board in a vacuum facing copper chamber, the pressure in the vacuum facing copper device should be kept at about 1×10−3 Torr, and then Argon and Oxygen, at a ratio of 1:3, should be inserted; the vacuum pressure should then be adjusted to about 5×10−3 Torr; facing copper is produced by spreading for 5 minutes, producing a thin CuO membrane on the “polyimide” isolation membrane “KAPTON”; the CuO membrane on the “polyimide” isolation membrane is placed into another vacuum with only Argon and the pressure is maintained at about 1×10−3 Torr.
