Technical Research Interest:

Research in the Dunn group involves the synthesis of inorganic and hybrid organic-inorganic materials and characterization of their electrical, electrochemical and optical properties. One of the principal themes which extends to most of the research activities is the use of sol-gel methods to synthesize a number of the materials studied in the group. This synthetic approach enables us to prepare materials which incorporate a wide variety of organic and biological dopants and are capable of developing unique microstructures and properties.

The research areas currently being investigated include (1) Electrochemical materials where we are investigating the electrochemical properties of materials with designed chemistry and microstructure; (2) Mesostructured materials based on the self-assembly processes which occur upon addition of surfactants to sol-gel materials; (3) Bio-hybrid materials in which biomolecules are encapsulated within sol-gel derived inorganic matrices; (4) Biomolecular materials where we try to exploit biological structures for engineering applications. We also demonstrate the utility of these materials in various device applications. Among the topics being investigated are three-dimensional batteries, biological fuel cells, bio-sensors, nanodimensional biochemical reactors and nanowire arrays.
