Machine learning solves the who’s who problem in NMR spectra of organic crystals

A team of EPFL researchers has combined a large database of 3D structures with a machine learning model of chemical shifts and topological representations of molecular environments to allow for the probabilistic assignment of NMR spectra of organic crystals directly from their 2D chemical structures. They demonstrated the approach on seven molecular solids with experimental shifts and benchmarked it on 100 crystals using predicted shifts. The correct assignment was found among the two most probable assignments in more than 80% of cases. The paper, Bayesian Probabilistic Assignment of Chemical Shifts in Organic Solids, was published today in Science Advances.

Ab initio model of Ca2RuO4 perovskite in remarkably good agreement with available experimental data

NCCR MARVEL researchers at the University of Fribourg have tested the GW + EDMFT ab initio approach for correlated materials modelling. Using the insulator-metal transition in the perovskite Ca2RuO4 as a benchmark, they found that their parameter-free simulation was in close agreement with the available experimental data and that the extension to the nonlocal polarization and self-energy provided by GW are essential to attaining such accuracy. The calculations represent an important test and an encouraging result for the further application and development of the GW + EDMFT framework, the authors said.

Quantum physics across dimensions: unidirectional Kondo scattering

NCCR MARVEL researchers Ana Akrap and Oleg Yazyev formed part of an international team led by EPFL scientists who unveiled a unique quantum-mechanical interaction between electrons and topological defects in layered materials. Only observed in engineered atomic thin layers, the phenomenon can be reproduced by the native defects of lab-grown large crystals, making future investigation of Kondo systems and quantum electronic devices more accessible. EPFL journalists report on the phenomenon below.

U.S. presents Materials Genome Initiative strategic plan

The Materials Genome Initiative was launched in 2011 to accelerate the discovery, design, development, and deployment of new materials by harnessing the power of data and computational tools in concert with experiment. The U.S. National Science and Technology Council has prepared the 2021 Materials Genome Initiative Strategic Plan, which updates and replaces the previous plan and reflects the significant advances that have been made over the past ten years.
