Solar Cell Researcher Explores Nanotech Possibilities

A UT Dallas researcher envisions a time soon when plastic sheets of solar cells are inexpensively stamped out in factories and then affixed to cell phones, laptops and other power-hungry mobile devices. And a new $330,000 grant from the National Science Foundation should help him come closer to realizing that vision. Many researchers are investigating the development of flexible solar cells in hopes of improving efficiency and lowering manufacturing costs, however Walter Hu’s novel approach would use nanoimprint lithography to produce precisely nanostructured devices rather than using chemical methods of manufacturing.

Sensitive Biosensors Could Transform Diagnostics

UT Dallas nanotechnology researcher Walter Hu has received a $400,000 grant to develop an innovative and manufacturable nanoelectronic biochip that can detect individual molecules. “The motivation for this project came from a growing synergy between biology and electronics,” said Hu, an assistant professor of electrical engineering in the Erik Jonsson School of Engineering and Computer Science. “In the long run, improved electronic sensors could have a considerable impact on a wide-range of disease diagnostics, in particular for point of care or future home diagnostics, overcoming the limitations of today’s optical sensors, which require bulky and expensive equipment.....
