Amber and Senja’s work on the cover of J. Chem. Theory Comput.
Mace et al. present TuTraSt, a novel algorithm to predict self-diffusion of a mobile guest particle in a crystalline material. It detects the energies at which diffusion paths are formed, allowing for easy identification of diffusive systems, and furthermore partitions the potential energy field into energy basins and transitions states. This TUnnel and TRAnsition STate search algorithm permits a transition state theory (…)
Sam’s MOF nanoreactor in Nature Comm
Sam and Pete showed how a combined experimental and computational study can turn a MOF into a nanoreactor to make an impossible molecule. For more details see their article in Nat Comm here [su_posts order=”desc”]

News and Views in Nature
Seth Cohen wrote a nice Nature News & Views (see here) on our work (see here) about Chemical Intuition
Interview with Radio Swiss about failed experiments
Les riches enseignements des expériences ratées Lors dʹune découverte scientifique, seuls les résultats de lʹexpérience réussie sont publiés. Or, pour arriver à une découverte scientifique publiable, il faut souvent beaucoup dʹéchecs et dʹintuitions. Des chercheurs de lʹEcole polytechnique fédérale de Lausanne (EPFL) ont développé une méthode pour récolter toutes ces tentatives ratées rendues invisibles et (…)
