Healable composites

Reversing fatigue in carbon-fiber reinforced vitrimer composites

To address the irreversibility of fatigue in polymer composites, a recent study showed that vitrimeric polymers can be used to reverse the fatigue damage through topological rearrangement of the marcomolecular network, self-healing the polymers. To...

Quenching nanocrystals

Fast Intrinsic Emission Quenching in Cs4PbBr6 Nanocrystals

Cs4PbBr6  belongs to the family of 0D metal halides, with separated and isolated [PbBr6]4- octahedra. These systems, in both nanocrystal and bulk forms, have been reported as being either non-emissive or green-emissive at room temperature...

Halide perovskites: efficient & accurate DFTB simulations

The fundamental understanding of the material properties of metal halide perovskites is critical to improving the stability and efficiency of future solar cells devices. Computational simulations have been proven to be a valuable tool to...

PHIP-X NMR enhancement

Strong NMR enhancement: PHIP-X

NMR signals are often too weak for many chemical and biomedical applications such as reaction monitoring or the real time investigation of metabolism in-vivo. A new method has been developed to enhance NMR signals: parahydrogen-induced...

15NMR-shielding-UN

Exceptional Uranium-Nitride Triple Bond Covalency confirmed with NMR

The Liddle group continues to deeply probe the unusual nature of the actinide-main group bonds through combined experimental and computational studies. We previously highlighted the first U-N triple bonds along with a number of other...

Optical and photoluminescence properties of gold and silver nanoclusters

Silver and gold nanoclusters (NCs) have proven to be efficient and stable, with optical and emissive properties that can be tuned by changing the cluster’s geometric and electronic parameters. Due to the dependence of size,...

Low-order scaling and accurate GW calculations with ADF

The GW method has become an increasingly popular method to calculate charged excitations in molecules. However, achieving consensus between different GW codes is challenging since GW calculations are very sensitive with respect to many technical...

POM electron sponge

Transformable Polyoxometalates, Sustainable Nanoelectronics

Molecular metal oxides, or more notably polyoxometalates (POMs) are being researched for over a century. Their structure benefits from very high stability, whose inherent connectivity relies predominantly on metal-oxygen bonds. Theoretical insights into the bonding...

Aqueous speciation of polyoxometalates

Polyoxometalates self-assembly in aqueous solution is still a subject under study. This is due to the high complexity that involves describing all the chemical equilibria. Experimental techniques investigated this matter with great successes yet more...

Birnessite intercalation ReaxFF

Capacitive mechanism of birnessite uncovered by experiments and simulations

The adsorption and intercalation of ions from the electrolyte into the interlayers of the electrode material is a key process in electrochemical energy storage. It is described by two adsorption extremes: 1) adsorption involving mainly...
