14 December 2017 – Congratulations to group members Emily Boyd and Will Moore, who have been named recipients of Undergraduate Research Awards by the Center for Undergraduate Research at KU! These awards will support Emily and Will's research on metal-mediated energy conversion in Spring 2018. Well done!

29 November 2017 – Amit's research has been featured on the cover of Chemistry – A European Journal! Our paper examines the structural and electronic effects of Lewis acidity in heterobimetallic complexes. The results suggest that the Lewis acidity of metal ions could be used to reliably tune the electrochemical properties of new catalysts.

20 October 2017 – Congratulations to Wade Henke, recipient of the Paul R. Sharp Graduate Award in Inorganic Chemistry. This prize was awarded for Wade's top oral presentation at the Midwest Regional ACS Meeting, titled "Understanding photodegradation of manganese tricarbonyl catalysts for CO2 conversion." Well done, Wade!
