Past Events & Seminars
Our laboratory has developed a new approach to the stereoselective functionalization of unsaturated hydrocarbons. Traditional approaches have relied on metal-catalyzed C-H bond activation. We have... View »
Two topics will be covered in the general area of tunneling microscopy: looking at surface dynamics of glasses on a millisecond to hour scale, and excited state dynamics of nanomaterials on the... View »
Protein and RNA folding and binding reactions are generally quite fast and involve small free energy differences. That speed has proven useful when comparing computer simulations of protein and... View »
Saturated oxygen and nitrogen heterocycles, e.g. pyrrolidines, morpholines and tetrahydrofurans, are prevalent in bioactive small molecules. The development of enantioselective cyclizations of... View »
Professor Hema Karunadasa works with colleagues in materials science, earth science, and applied physics to drive the discovery of new materials with applications in clean energy. Her group... View »
Chemoselective reactions that occur under mild conditions are required to synthesize and
functionalize biomolecules. To that end, ligation of a-nucleophiles with a-oxo-aldehydes
or... View »
Development of methods to prepare various organic compounds of synthetic, biological, and medicinal significance in a cost-effective, efficient, reliable and selective manner is vital to advances... View »
Metallic surfaces perform many chemical transformations that hold promise for the future energy economy, including N2 reduction, NH3 oxidation, and alkane synthesis, but surfaces are difficult to... View »
ABSTRACT:
Chemical synthesis is responsible for significant emissions of carbon dioxide worldwide. These emissions arise not only due to the energy requirements of... View »
The direct coupling of mechanical forces in polymers to covalent chemical reactions has opened new opportunities in chemical reactivity, stress-responsive materials, and mechanochemically active... View »
Polymer science just celebrated its centennial, and the global polymer market now exceeds $500 billion per year. Despite this history and stature, many fundamental aspects of the way polymers... View »
ABSTRACT:
Our research program revolves around the synthesis and use of fused heterocyclic stable carbocations, such as acridinium, helicenium and triangulenium ions. These... View »
The frontier in renewable energy applications lies in designing functional energy materials from molecular and nanostructured components as well as integrating these functional entities into... View »
