CYCLO70: A New Challenging Pericyclic Benchmarking Set for Kinetics and Thermochemistry Evaluation
Here, a new challenging benchmarking data set for cycloaddition reactions, CYCLO70, is presented and analyzed. CYCLO70 has been generated with the specific aim of being representative of the most chal...

Improving the Reliability of, and Confidence in, DFT Functional Benchmarking through Active Learning
Validating the performance of exchange-correlation functionals is vital to ensure the reliability of density functional theory (DFT) calculations. Typically, these validations involve benchmarking dat...

Reactions of ribose relevant to the origin of metabolism apparently occur in aqueous microdroplets but not in bulk water. Why not? Computations suggest it's electric fields. Thanks

What better first post than to share our last two preprints! ๐ In one, we study how electric fields modulate chemical reactivity, and in the second, we explore a data-efficient strategy for the assembly of more representative benchmarking datasets for DFT validation.
