Femtosecond X-ray solution scattering reveals that bond formation mechanism of a gold trimer complex is independent of excitation wavelength

open access: yesStructural Dynamics, 2016
The [Au(CN)2−]3 trimer in water experiences a strong van der Waals interaction between the d10 gold atoms due to large relativistic effect and can serve as an excellent model system to study the bond formation process in real time.

Learning to Predict Chemical Reactions [PDF]

open access: yesJournal of Chemical Information and Modeling, 2011
Being able to predict the course of arbitrary chemical reactions is essential to the theory and applications of organic chemistry. Approaches to the reaction prediction problems can be organized around three poles corresponding to: (1) physical laws; (2) rule-based expert systems; and (3) inductive machine learning.

Designing covalent organic frameworks with Co-O4 atomic sites for efficient CO2 photoreduction

open access: yesNature Communications, 2023
A class of inexpensive aminoanthraquinone organic dyes are shown to facilitate visible-light-driven CO2 reduction. Overall reaction efficiencies were found to be optimal when both electron donating and accepting groups were on a single dye molecule.
