The University of Maryland MRSEC grants ended in September 2013 after 17 years of successful operation. This site remains as a history of the center, but will not be actively maintained.

Senior Investigators

Advances in electrical energy storage are needed to utilize energy from alternative sources such as solar and wind, and to realize all-electric vehicles. This Maryland MRSEC seed team is developing heterogeneous nanostructured electrodes for use in electrostatic capacitors, ionic supercapacitors, and batteries. The use of multiple materials allows different materials to serve different functionalities (ionic storage, electrical conductivity, mechanical strength), increasing overall performance compared to single-material electrodes. The Maryland MRSEC seed team is approaching the problem by using self-assembly of materials in porous anodic aluminum oxide (AAO) templates to create heterogeneous core-shell nanowires or nanotubes. Materials are deposited through electrochemistry or atomic layer deposition (ALD).
