DFT Approach to the Calculation of Mössbauer Isomer Shifts [PDF]
With the help of a recently suggested computational scheme [J. Chem. Phys. 2007, 127, 084101], Mössbauer isomer shifts are calculated within the context of density functional theory, for a series of iron containing compounds. The influence of the choice of a density functional and of the truncation of a basis set on the results of calculations is ...

DFT Calculation of Carbon-Doped TiO2 Nanocomposites
Titanium dioxide (TiO2) has been proven to be an excellent material for mitigating the continuous impact of elevated carbon dioxide concentrations. Carbon doping has emerged as a promising strategy to enhance the CO2 reduction performance of TiO2. In this study, we investigated the effects of carbon doping on TiO2 using density functional theory (DFT ...
