A flexible and scalable scheme for mixing computed formation energies from different levels of theory

open access: yesnpj Computational Materials, 2022
Computational materials discovery efforts are enabled by large databases of properties derived from high-throughput density functional theory (DFT), which now contain millions of calculations at the generalized gradient approximation (GGA) level of ...

Understanding density functional theory (DFT) and completing it in practice

open access: yesAIP Advances, 2014
We review some salient points in the derivation of density functional theory (DFT) and of the local density approximation (LDA) of it. We then articulate an understanding of DFT and LDA that seems to be ignored in the literature.

Electronic structure and de Haas–van Alphen frequencies in KFe2As2 within LDA+DMFT

open access: yesNew Journal of Physics, 2014
Recent density functional theory (DFT) calculations for KFe _2 As _2 have been shown to be insufficient to satisfactorily describe angle-resolved photoemission (ARPES) measurements as well as observed de Haas–van Alphen (dHvA) frequencies. In the present

Statistical learning goes beyond the d-band model providing the thermochemistry of adsorbates on transition metals

open access: yesNature Communications, 2019
Assessing catalytic mechanisms using DFT calculations greatly aids catalyst design, but is impractical for large molecules. Here the authors develop a statistical learning-based thermochemical model for estimating adsorption of organics onto metals ...

Density functional theory + U modeling of polarons in organohalide lead perovskites

open access: yesAIP Advances, 2016
We investigate the possible formation of polarons in four organic perovskites (CH3NH3PbI3, CH3NH3PbBr3, CH3NH3PbCl3, and CH3NH3PbI2Cl1) using a density functional theory (DFT) calculations with local potentials and hybrid functionals.

Heterogeneous catalyst design by generative adversarial network and first-principles based microkinetics

open access: yesScientific Reports, 2022
Microkinetic analysis based on density functional theory (DFT) was combined with a generative adversarial network (GAN) to enable the artificial proposal of heterogeneous catalysts based on the DFT-calculated dataset.

EXAFS, DFT, light-induced nucleobase binding, and cytotoxicity of the photoactive complex cis-[Ru(bpy)2(CO)Cl]+ [PDF]

open access: yes, 2010
The aqueous photochemistry of cis-[Ru(bpy)2(CO)Cl]+ (1) was investigated at 310 K and under visible light (white) irradiation by NMR and ESI-HR-MS. Complex 1 releases a Cl ligand, coordinates a solvent molecule, and forms the complex cis-[Ru(bpy)2(CO ...

Synthesis, Characterization and DFT-Based Investigation of a Novel Trinuclear Singly-Chloro-Bridged Copper(II)-1-Vinylimidazole Complex

open access: yesActa Chimica Slovenica, 2016
A novel trinuclear copper(II) complex [Cu3(µ2-Cl)2Cl4(1-Vim)6] with monodentate 1-vinylimidazole (1-Vim) and chloro ligands has been prepared and experimentally characterized by elemental analyses, Thermogravimetry (TGA, DTG, DTA), X-ray single crystal ...

Modelling Catalyst Surfaces Using DFT Cluster Calculations [PDF]

open access: yesInternational Journal of Molecular Sciences, 2009
We review our recent theoretical DFT cluster studies of a variety of industrially relevant catalysts such as TiO2, γ-Al2O3, V2O5-WO3-TiO2 and Ni/Al2O3. Aspects of the metal oxide surface structure and the stability and structure of metal clusters on the support are discussed as well as the reactivity of surfaces, including their behaviour upon ...
