WebApr 10, 2024 · Through experimental results and DFT calculations, urotropine doping results in two types of active sites, including the top N atoms of urotropine and the nearby C atoms of the CNTs, which both favor the “end-on” adsorption of O 2 and the *OOH intermediates, reduce the possibility of O-O bond breakage, and favor the 2e-ORR pathway. WebApr 23, 2013 · We performed DFT calculations to investigate the hybridizations of (6, 0) CNTs and GNRs through peptide linkages. Two sites of edges and sidewalls of GNRs are considered to participate in the hybridization processes through the peptide linkages (Fig. 2).It is noted that both sides of peptide group (the carbon atom of carbonyl and the …

WebComposite MoS2/carbon nanotube material has been produced by hydrothermal decomposition of a mixture of multiwall carbon nanotubes (CNTs) and a water solution of ammonium molybdate and thiourea. Transmission electron microscopy and Raman spectroscopy showed formation of MoS2 layers on the CNT surface and MoS2 flakes. X … WebApr 7, 2024 · Density functional theory (DFT) calculations further demonstrate that the enhanced HER/OER performance should be attributed to the synergistic effect of V o and heteostructure that improve the conductivity of N-NiMoO 4 /Ni/CNTs and facilitatethe desorption of reaction intermediates. euroasian auto inc in wichita ks

WebFeb 13, 2024 · Abstract. In this study, quantum mechanical calculations, such as density functional theory (DFT), have been employed to determine the active positions of … WebNov 14, 2014 · Density functional theory (DFT) is a type of electronic structure calculation that has rapidly gained popularity. In this article, we provide a step-by-step demonstration of a DFT calculation by hand on the helium atom using Slater’s X-Alpha exchange functional on a single Gaussian-type orbital to represent the atomic wave function.
