microstructure is nano-composite[11]. Therefore, the cross-sectional HRTEM images, selected area diffraction patterns (SADP), and dark-field TEM images for CrAlN, CrAlC0.17N0.83 and CrAlC coatings were observed... of CrAlCxN1-x coatings is nanocomposites consisting of nano-sized Cr(Al, N) crystallines surrounded by amorphous carbon phase. Also, surface becomes smoother by the microstructural changes of CrAlCxN1-x......

Immobilization of laccase on amine-terminated magnetic nano-composite by glutaraldehyde crosslinking method XIAO Hai-yan(肖海燕), HUANG Jun(黄 俊), LIU Cheng(刘 诚), JIANG De-sheng(姜德生) Key Laboratory...: The immobilizing procedure has great influence on the activity of the immobilized laccase. The laccase was immobilized on copper tetraaminophthalocyanine (CuTAPc)-Fe3O4 magnetic nano-composite......
by painting, sintering and annealing through a sol-gel technique. The microstructure, morphology and grain size of coatings and the electrochemical properties of the anodes were investigated by XRD, DTA, SEM, TEM and CV. It is demonstrated that the anodic coatings consist of solid solution (Sn, X)O2 (X represents Ru or Ti) phases. The average grain size of the coatings is about less than 30nm. When......
