We investigate the structure and mobility of single self-interstitial atom and vacancy defects in body-centered-cubic transition metals forming groups 5B (vanadium, niobium, and tantalum) and 6B (chromium, molybdenum, and tungsten) of the Periodic Table. D ...
The thermochem. of the RuO42- + MnO4- RuO4- + MnO42- redox reaction in aq. soln. is studied by sep. d.-functional-based ab initio mol.-dynamics simulations of the component half reactions RuO42- -> RuO4- + e- and MnO42- -> MnO4- + e-. We compare the result ...
NOVELTY - The component partially or wholly comprises pigmented ceramic. The pigment comprises nanoparticles of metal of group IB in periodic table, alkaline metals or their alloy, coated with a layer of silica such as crystalline silica. The crystalline s ...
Recently, we have introduced a scheme for optimizing atom-based nonlocal external potentials within the framework of d. functional theory (DFT) in order to systematically improve the description of mol. properties [Phys. Rev. Lett. 93, 153004 (2004); J. Ch ...
The attempt to prep. hitherto unknown homopolyat. cations of sulfur by the reaction of elemental sulfur with blue S8(AsF6)2 in liq. SO2/SO2ClF, led to red (in transmitted light) crystals identified crystallog. as S8(AsF6)2. The X-ray structure of this salt ...
A review discusses the basic concepts of the Car-Parrinello method, some of the recent methodol. extensions, focusing on aspects with potential interest for applications in medicinal chem., and the advantages and limitations of new modeling tools. ...
Density-functional theory is used to model interstitial iron and its complexes with aluminum in Si-rich SiGe alloys with Ge concentration up to 8%. Both short-range and long-range defect-Ge interactions are considered. It is found that Fe prefers Si-rich r ...
Energies computed by B3LYP and other popular DFT functionals are flawed by systematic errors, which can become considerable for larger mols. These errors, predominately due to inadequacies in assessing longer-range nonbonded attractive effects (dispersion) ...

We add an effective atom-centered nonlocal term to the exchange-correlation potential in order to cure the lack of London dispersion forces in std. d. functional theory. Calibration of this long-range correction is performed using d. functional perturbatio ...
