Research Interests: 

Solar energy conversion, in both natural and artificial systems, involves the absorption of a photon that can then lead to a series of energy and electron transfer events. Research in the Anna group focuses on understanding these photoinitiated processes. More specifically we are interested in exploring (1) the interplay of vibrational motion with both electronic energy transfer and electron transfer reactions, and (2) the role the environment plays in these processes. To begin to answer these questions we employ both well-established and novel multidimensional spectroscopic techniques to explore photoinitiated processes in a range of systems, spanning interests in biology, chemistry, and physics.

Marsha Lester and Larry Sneddon honored in Dallas

Marsha I. Lester, the Edmund J. Kahn Distinguished Professor, and Larry G. Sneddon, the Blanchard Professort of Chemistry, were both honored with national awards at the ACS meeting. Marsha was awarded the Francis P. Garvan-John M. Olin Medal, which recognizes distinguished service to chemistry by women chemists. Larry received the F. Albert Cotton Award, which was established to recognize distinguished work in synthetic inorganic chemistry. Both Marsha and Larry were honored at the awards banquet in Dallas.

 

Penn Chemistry adds two new faculty members for 2015

Associate Professor Elizabeth Rhoades (Yale) will be joining the Department in July 2015. The Rhoades lab studies protein folding, misfolding, and dynamics.

 

Neil S. Tomson, currently at Los Alamos National Laboratory, will join the Department at the same time as an Assistant Professor of Inorganic Chemistry.

 

We are thrilled to be able to welcome Liz and Neil to Penn Chemistry.

Eric Schelter's Research Featured at Science on Tap

Assistant Professor Eric Schelter brought chemistry to the people when he took part in Philadelphia's Science on Tap series at National Mechanics. Interested members of the general public were on hand to enjoy food, drink, and a spirited conversation about the important, yet little discussed, topic of rare earch metals.

Research Interests: 

Our group performs synthetic inorganic and organometallic chemistry as a way of investigating new concepts in structure, bonding, catalysis, and materials chemistry.  The research involves the use of rigorous air-sensitive synthetic techniques and draws on a wide range of physical methods for characterizing novel compounds. 

 

With a particular interest in energy problems, our work takes advantage of modern concepts in bonding theory to generate materials that can influence how energy from renewable sources is collected, stored, and released.  To do this, we develop both new catalysts for reactions that store energy in chemical bonds and battery materials that can reversibly deliver multiple electrons with minimal energy loss.  Our current areas of focus include:

 

• Understanding the effects of molecular-scale electrostatic fields on electronic structure and reactivity, particularly as they relate to both bioinorganic chemistry and homogeneous catalysis.

 

• Developing molecular cluster compounds that incorporate redox-active ligands as a way of modeling the chemistry occurring on the surfaces of heterogeneous, metallic catalysts.

 

• Generating molecules for use as multi-electron, redox-flow battery materials, especially those that can undergo potential inversion.
