When carbon nanotubes(CNTs) are used as negative electrode materials of Lithium ion battery, li not only insert in their pipes but also can insert the stitches between pipes, so CNTs can offer a lot of space for li encasing. This special microstructure makes the li a little insetting measurement and it is advantage for improving the charge/discharge capacities and current density. Two kinds of CNTs were prepared in this paper, the size and morphology and structure of the CNTs were determined with X-ray diffraction (XRD) and Transmission Electron Microscope (TEM). The charge/discharge characters of CNTs were tested with electrochemical detector and the results showed that there were different between two kinds of CNTs. The CNTs (A) with little d002 had higher initial discharge capacity. At first cycle there was 808.9mAh/g discharge capacity, 214.5mAh/g irreversible capacity and 73.4% discharge efficiency The CNTs (B) with bigger d002 had initial discharge capacity of 1064.1mAh/g, the first irreversible capacity 627.1mAh/g and 41.1% discharge efficiency. Two kinds of CNTs had better recycle character © 2011 IEEE. Source

A kind of high heat-resistance and corrosion coating which can be used to resist at 550°C, salt spray resistance time to 168h was prepared by boron modified silicone resin for raw material, glass flake as filler, titanium dioxide as pigment, silane coupling agent as additives. The results showed that the optimal coating performance was obtained at pigment grinding time 2h, high speed dispersion coatings 2h, the pigment to binder ratio of 0.3:1, KH-560 account for the total coatings 2.1%, glass flake pigments account for the mass ratio of 75%. The paint film has good Conventional performance. © 2011 IEEE. Source

Aluminum plastic foamed mask package is commonly used for the packaging of tablets in the pharmaceutical companies and defective tablets can be produced during the production of the packaging. This paper studies several key algorithms of defect detection for tablets in aluminum and plastic package and designs the auto- detection software which applies an image processing and recognition technology. Firstly, it uses a weighted filtering method of color images to pretreat the tablet images. Secondly, it classifies the tablets into color and white tablets, and adopts a significant target segmentation method based on the visual significance analysis in order to respectively segment two kinds of tablets from the background image. Then detects the edges of tablets by Canny operator. Finally, it adopts the connected component labeling algorithm to detect the tablets lacking of numbers and other defects including misshapen tablets and tablets with scratches by the SVM algorithm. Large amounts of experiment results demonstrate that the system has greater accuracy and higher stability and speed. © Jiang et al. Source
