Emmanuel Karaiskos、Ioannis A. Bitsanis、Spiros H. Anastasiadis2009-11-10Journal of Polymer Science Part B Polymer Physics

Abstract Monte Carlo computer simulations of end‐tethered chains grafted onto a hard wall have been performed. The chains were modeled as self‐avoiding chains on a cubic lattice at athermal solvent conditions. The simulations spanned a wide range of chain lengths, N (100–1000, i.e., up to molecular weights of a few hu…

Oxidation of CO Catalyzed by a Cu Cluster: Influence of an Electric Field

Wei Liu、Yonghao Zhao、Renqin Zhang 等 6 位作者2009-11-10ChemPhysChem

Adsorption ability and reaction rate are two essential parameters that define the efficiency of a catalyst. Herein, we implement density functional theory (DFT) and report that CO can be oxidized by a pyramidal Cu cluster with an associated reaction barrier E(b)=1.317 eV. In this case, our transition state calculation…
