Pure strain effects in catalysis
In new research, Adit Maark and co-workers showed the possibilities for pure strain effects in catalysis, and showed that these effects can be cleanly separated from ligand effects computationally, suggesting means to design new catalysts subject to mechanical strain. [More...

Peterson named to editorial board of Scientific Reports
Professor Peterson has been named to the editorial board of Scientific Reports
, an open-access journal published by Nature
. The open sharing of scientific findings to a broad audience fits well with our group's philosophies on open-source software and data sharing.

Finding complex adsorbate states
Catalyst surfaces can involve considerable complexity, such as stepped surfaces and interactions between multiple adsorbates. Discovering the most stable configurations in these complicated environments can be quite daunting. We show, in a new paper
in Topics in Catalysis, how a minima hopping technique can simplify this search. [More...

Ben Johnson and co-workers identify atomic role of sulfur poisoning in methanation
The catalytic conversion of biomass to synthetic natural gas via supercritical-water gasification has the potential to be a high-efficiency, feedstock-agnostic means to produce conventional hydrocarbon fuels and fertilizers from waste biomass. However, in real operation, the ruthenium catalysts in use tend to rapidly degrade over time. In a new paper
, collaborators from Brown University and the Paul Scherrer Institut (Switzerland) have traced this effect to sulfur poisoning and identified the atomic role of sulfur in the deactivation of the catalyst. [More...

Cory Hargus wins 'Award of Excellence'
Congratulations to Cory Hargus, who won
the "Award of Excellence" at the National Collegiate Research Conference, held in Cambridge, MA, this past Saturday. Cory won the award for his poster presentation on his research conducted in our group, entitled "Solar Enriched Biofuels Via Oxidizable Metal Catalysts". Well deserved!
