Savariar and Krishnamoorthy in the Thayumanavan group develop a platform technology for functionalizing nanoporous membranes. This has the potential to develop structures that will result in fundamental understanding of transport (e.g. proton) through functionalized nanopores. Read the article in Nature Nanotechnology.

Usha Viswanathan, a PhD student the Auerbach group, recently presented a paper titled "Modeling Proton Transfer in Zeolites: Effects of Acid Site Heterogeneity," at the XIVth International Workshop on Quantum Atomic and Molecular Tunneling in Solids, in Houston, Texas. Ms. Viswanathan's work focuses on the development of atomic-scale models to understand how protons move in confined environments such as three dimensional networks of self-assembled organic polymers, and of inorganic silicon-oxygen materials. Her work, in the Journal of Physical Chemistry C 2007, 111, 18341-18347, shows how proton motion is influenced (made faster or slower) by motions of the confining scaffold. Applications of her work include designing new proton exchange membranes for fuel cells, and designing new acid catalysts for biofuel production.
A Facile Method for the Synthesis of Cleavable Block Copolymers from ATRP-Based Homopolymers

Block copolymers continue to garner significant interest due to their propensity to form self-assembled nanostructures, the morphologies of which are determined by the mutual compatibility and the volume fractions of the constituent blocks. If one were to create nanoporous structures from these, it is necessary that one of the blocks is selectively degraded after the assembly
