Highlights with ‘Relativistic DFT’

ADF developer Jochen Autschbach wins Schoellkopf Medal

Many congratulations to Jochen for winning the 2019 Schoellkopf Medal! In ADF, Jochen has implemented very useful methods for spectroscopic properties (NMR, EPR, NLO), including accurate and efficient relativistic treatment and analysis tools. Check out...

Enhanced electrocatalytic water splitting on MoTe2

A new method of extracting hydrogen from water more efficiently could help underpin the capture of renewable energy in the form of sustainable fuel. Transition metal dichalcogenides are promising electrocatalytic materials for the hydrogen evolution...

Understanding Band Structures – “Mirrors of Bonding” in Perovskite Crystals

Band structures are a widely used tool in solid state physics and materials science to analyze the electronic structure of crystalline materials. However, the band structure of materials relevant for actual applications are often rather...

Main Group Elements as Transition Metals: Alkaline Earth Octacarbonyls with 18-electrons

Generally, main group elements prefer obeying the 8-electron rule; while the transition metal elements tend to follow the 18-electron rule. Recently, scientists reported the isolation and spectroscopic identification of the eight-coordinated alkaline earth carbonyl complexes...

SO-HALA NMR Chemical Shifts: General Trends Across the Periodic Table Explained with ADF

In a recently published JCTC article Jan Vicha and coworkers explain the SO-HALA (Spin-Orbit Heavy Atom on the Light Atom) NMR chemical shifts across the periodic table based on relativistic DFT calculations with spin-orbit coupling ZORA...

Benchmark: density functionals and settings for band gaps

Jetsabel Figueroa, MSc. student in the OptoElectronics group at the TU Delft, benchmarked band gap calculations with BAND. During her internship with SCM she made use of the python scripting tool PLAMS (see the script with...

Novel Thorium Arsenic Multiple Bonds

A recent Nature Communication paper reports thorium complexes with Th-As multiple bonds, stabilized by bulky triamidoamine ligands. The bonding interactions in the novel thorium arsinidiides (ThAs(H)K and ThAs(H)Th) and arsenido (ThAsTh) are studied with relativistic...

Covalent Bonding in Heavy Actinides

The separation of highly radioactive minor actinides from lanthanides and other fission products within the nuclear fuel cycle is crucial in both the recycling of used nuclear fuel and as a prelude to waste storage....

5f covalency in Americium hexachloride

The Cl K-edge XAS of Americium(III) Hexachloride were simulated and analyzed based on spin-orbit DFT transition dipole moment method. Direct evidence of 5f and 3p orbital mixing in Am–Cl bond was observed. Combining experimental Cl K-edge XAS and theoretical simulation, the comparison between AmCl63-...

A general Pd-catalyzed pathway to β-lactams

In a recent Science paper the Gaunt group reports facile access to β-lactams via palladium-catalyzed coupling of aliphatic amines and carbon monoxide. The scope of the reaction is remarkably broad; over 40 substrates are illustrated, bearing a...
