    TROY, N.Y., Feb. 23 /PRNewswire/ -- Evident Technologies (Evident)
 announced it has received an SBIR (Small Business Innovation Research) grant
 from the Office of Strategic Defense for a project to develop a high
 performance thermoelectric material using Evident's proprietary quantum dot
 technology.  The quantum dot thermoelectric project is scheduled to be
 completed in June of 2005. Dr. Gregory Scholes of the University of Toronto
 will be collaborating with Evident Technologies to measure and characterize
 these materials. The award is under the United States Department of Defense's
 Office of Strategic Defense SBIR Phase 1 proposal OSD04-EP3
 "Nanostructure-Enhanced Bulk Thermoelectric Materials" and the program is
 managed by the Navy's Office of Naval Research.
     The objective of the project is to demonstrate that quantum dots can be
 used to produce an improved thermoelectric nanomaterial by engineering thermal
 and electronic properties to achieve increased efficiencies. Thermoelectric
 materials can be fashioned into devices to create electricity from temperature
 differences or into solid-state cooling devices. However an inherent
 shortcoming of existing thermoelectric materials is that they make for
 inefficient devices, either for cooling or energy conversion. Evident will
 work to develop an advanced thermoelectric nanomaterial that, because of its
 improved efficiencies, could offer significant cost and performance benefits
 for both military and commercial applications.
     "By using quantum dots in a thin film, our goal is to reinvigorate the
 development of thermoelectric technologies to obtain unprecedented device
 efficiencies.  This should substantially help increase the performance and
 reduce the cost of a wide range of thermoelectric devices," said Clint
 Ballinger, Chief Executive Officer of Evident.
     "Thermoelectric devices have the potential for a wide range of
 applications," said Dr. Gregory Scholes of the University of Toronto.
 "Thermoelectric devices can be used as a solid-state cooler to remove heat
 from solid-state electronics or used for generating electricity in wide
 variety of critical systems ranging from submarines or aircraft to space
 systems. By using an innovative quantum dot based material, we hope to see
 greater device efficiencies."
     Dr. Scholes is Assistant Professor in the Department of Chemistry,
 University of Toronto. His research program includes developing new methods
 for the synthesis of semiconductor quantum dots, the application of ultra-fast
 laser experiments and theory to elucidate the electronic properties of quantum
 dots and organic polymers, and the study of light-induced magnetism.
