Maximum Flux for Fast Neutrons

August 28, 2013 8:12 am | Award Winners

Analysis of nuclear materials using fast neutron sources has become more common. Greater intensity, or flux (neutrons per unit area), of these sources ensures more effective analysis. However, in current devices samples must be placed a distance from the neutron source emitter where the flux of the fast neutron is small. The “High Flux Fast Neutron Source” Model DD-109X, introduced by Adelphi Technology Inc. and the Univ. of Florida, changes that by positioning the sample to be irradiated in the acceleration chamber next to the high-voltage target that produces the fast neutrons.

Biologist discovers mammal with salamander-like regenerative abilities

September 26, 2012 5:38 pm | News | Comments

For years biologists have studied salamanders for their ability to regrow lost limbs. But amphibian biology is very different than human biology, which makes the recent discovery of a small African mammal with an unusual ability to regrow damaged tissues potentially crucial to new research in regenerative medicine.

Experiment corrects prediction in quantum theory

September 20, 2012 8:03 am | News | Comments

An international team of scientists is rewriting a page from the quantum physics rulebook using a University of Florida laboratory once dubbed the coldest spot in the universe. The Microkelvin laboratory is one of the few places cold enough to generate and study the Bose-Einstein Condensate, a state of matter in which individual particles act as a whole. Recent research has confirmed, and corrected, certain predictions about the phase transitions for this state of matter.

Manufacturing method paves way for quantum dot-based LEDs

September 6, 2011 6:55 am | News | Comments

University of Florida researchers may help resolve the public debate over America's future light source of choice: Edison's incandescent bulb or the more energy efficient compact fluorescent lamp. It could be neither. Instead, America's future lighting needs may be supplied by a new breed of light-emitting diode, or LED, that conjures light from the invisible world of quantum dots.

Researchers have recovered and analyzed the oldest fossil evidence of fingernails in modern primates, confirming the idea nails developed with small body size and disproving previous theories nails evolved with an increase in primate body size.

Study shows tundra fires could accelerate climate warming

July 29, 2011 5:09 am | News | Comments

After a 10,000-year absence, wildfires have returned to the Arctic tundra, and a University of Florida study shows that their impact could extend far beyond the areas blackened by flames. With the amount of carbon released in these tundra wildfires, roughly twice the amount of greenhouse gases put out by the city of Miami in a year, the study suggests that these fires could impact the global climate.

Making plastic from discarded plant material

May 31, 2011 10:17 am | by Robert H. Wells | News | Comments

Plastic may compete with paper in the grocery line, but it doesn’t have to compete with the world’s food supply, according to Univ. of Florida researchers. They've developed a way to produce plastic that doesn't use valuable natural resources, such as food or fuel, for raw materials. The new method uses a strain of bacteria to create bioplastic from discarded plant material, such as yard waste.

Nanosponges speed semiconductor devices

August 31, 2005 8:00 pm | Award Winners

The semiconductor device industry is continually driven to improve performance. In order to achieve increasing speeds and decreasing costs, manufacturers have introduced new materials such as ultra-low k dielectrics. These dielectrics, however, are soft, fragile, and can be easily scratched and delaminated during chemical mechanical planarization. Researchers from Sinmat Inc., in a joint effort with the Univ. of Florida, have developed Soft, Elastic Nanosponge Materials that have significant advantages over to state-of-the-art slurries based on conventional particles.
