Highlights with ‘heavy elements’

Unraveling the stability of ThO2 nanoclusters

In the field of nanotechnology, the ultimate goal is to produce nanostructures with specially tailored properties that contrast with those in the bulk. Actinide dioxide nanomaterials play an increasingly important role in the design of...

Photochemical water oxidation by uranyl nitrate

Uranyl coordination chemistry enables a wide range of chemical transformations which have been recently reviewed by Arnold et al. [Chem. Rev. 2019, 10595]. Especially the photochemical properties of uranyl complexes are promising.Among all the photo-assisted...

Microstructure of doped lead halide perovskites from solid-state NMR

Multi-component lead halide perovskites have recently emerged as new promising materials for solar cells and light emitting devices. Essential to their remarkable performance is the notion of doping with inorganic and organic cations such as...

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...

Perovskite Band Structure & COOP Analysis – Advanced Tutorial

Whether you are a solid state physicist thinking of chemistry as too arcane or a chemist puzzled by band structure theory: Try out our new tutorial and learn how to neatly link these two fields,...

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...

Spin Orbit Coupling effect on spin-forbidden reaction mechanisms

A spin forbidden reaction occurs with a change of the total electronic spin from reactants to products. The mechanistic study is therefore not trivial, since the reaction does not occur on a single adiabatic potential...
