This breakthrough will enable fundamental scientific insights into single-molecule switching and bond formation between atoms and molecules. The effect of H/D quantum nature for geometry and nuclear magnetic shielding changes are analyzed. TiAl3 cluster as well as its interaction with hydrogen was characterized. Posted on May 14, 2013 by Camille. Fifth, a DFT study on the potential application of a prototype ZnO (6,0) zigzag SWNT as gas sensor for H 2, O2, CO, NH3 and NO2 shows that the electron-donor molecules (CO and NH3) tend to enhance the concentration of major carriers ( electrons), whereas the electron-acceptor molecules (O 2 and NO2) tend to reduce the concentration. Materials Science - Books Atom Probes; Atomic Force Microscopes (AFM) Electron Beam Sources; Fiber Analyzers;. The DFT models are used to understand how changes at the atomic and molecular levels influence behaviors we can see and touch. Density-Functional Theory (DFT) is one of the most prominent ab initio quantum chemistry tools available to provide insight about atoms, molecules, biomolecules, and beyond. Our results also showed that a TiAl3 cluster can hold up to twelve hydrogen atoms, corresponding to dissociation of six hydrogen molecules. Density-functional theory calculations have been used to investigate adsorption and surface dynamics of Pt atoms on MgO(001) surfaces with surface-functional hydroxyl groups. DFT-D and DFT-D2 energy corrections consider all pairs of atoms while DFT-D3 also consider triplets of atoms to account for three-body effects. €�Tulane gave me the chance to do the research that I wanted to do in the density functional theory of atoms, molecules and solids,” Perdew says.

O2 and NO2 can dissociate at the oxygen vacancy (VO) sites through filling the VO with one atomic O originated from the adsorbates. This one-atom-thick manufacture of carbon, uniquely, as well being hidden behind the scratching of a pencil-also discovered in England for over 400 years, combines extreme mechanical strength, exceptionally high electronic and Experimental works are accompanied by theory and computational models generally based on density functional theory and/or molecular dynamics calculations, providing an important support for studying the electronic properties. In this thesis, two types of complex hydrides doped with transition metals as potential hydrogen storage materials were investigated using density functional theory (DFT) calculations. Theoretical calculations were performed by Density Functional Theory (DFT) in order to elucidate several aspects of HFOs chemistry in the atmosphere. Theoretical Study of H/D Isotope Effects on Nuclear Magnetic Shieldings Using an ab initio Multi-Component Molecular Orbital Method. For example, how does the behavior of water molecules and sulfur oxide impact the creation of acid rain? We have theoretically analyzed the nuclear hydroxy acyl aromatic species using the gauge-including atomic orbital technique combined with our multi-component density functional theory.
