First-principles calculations based on density functional theory were carried out to investigate the structural and electronic properties of Pt substitution-doped boron nitride (BN) nanotubes. The electronic and structural properties were studied for substituted Pt in the boron and the nitrogen sites of the (BN) nanotube. The band gap significantly diminishes to 2.095 eV for Pt doping at the B site while the band gap diminishes to 2.231 eV for Pt doping at the N site. The band density increases in both the valence band and the conduction band after doping. The effects of the hardness and softness group 17 (halogen elements) were calculated by density functional theory (DFT). 相似文献

Since the two reports published in 1986 by the laboratories of R. Lerner and P. G. Schultz, it has been clearly established
that antibodies may be induced to act as catalysts in numerous chemical reactions. In all cases, catalytic antibodies were
elicited using a substratebased approach. In the present article, we propose an alternative and complementary enzyme-based
approach to generate catalytic antibodies. This approach uses the properties of anti-idiotypic antibodies to generate internal
images of enzyme active sites. Experimental results are discussed for polyclonal and monoclonal anti-idiotypic antibodies. 相似文献
