Chris Lyon, industrial liaison director of the Center for Environmentally Beneficial Catalysis, and Professor Bala Subramaniam display the benefits of the center's research. In his gloved hand, Lyon holds a flask of concentrated mineral acid that is currently used as catalyst in high octane fuel production. In his bare hand, he's holding a
solid acid catalyst, an environmentally beneficial alternative to concentrated liquid acids.

The intraocular retinal prosthesis consists of 16 electrodes arrayed on a 4-by-4 grid; these electrodes are stimulated by digitized images transmitted to the device from a camera mounted on a pair of glasses. The electrodes, in turn, stimulate the patient's remaining retinal neurons.

Injected into newly paralyzed or weak muscles, the BION™, which is approximately the size of two rice grains, receives command signals from a flat rubber coil that a patient places over an affected area. The transmission coil causes the bionic nerve to produce electrical stimulation pulses that activate adjacent neurons. Precisely placed, the device enables target muscles to be strengthened and retrained through a patient's individualized exercise regimen.

The cortical brain prosthesis is designed to mimic non-functioning regions of the brain's memory center. Connecting to brain tissue and taking over the function of neurons in the hippocampus - the part of the brain where short-term memories are encoded so that they can be stored as long-term memories elsewhere - the device may one day help those with brain damage from strokes, epilepsy and Alzheimer's disease.

Today's NEXRAD system (above) detects only the tops of tornados or even overshoots the tornadoes all together. Researchers now affiliated with the CASA ERC captured the image (below) using short-range radars that can resolve very fine structures within tornadoes-it is the highest resolution image of a tornado ever captured.
