Flexible silicon solar-cell fabrics may soon become possible

12/6/12

For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that is capable of being scaled up to many meters in length. The research, led by a Penn State University chemist, opens the door to the possibility of weaving together solar-cell silicon wires to create flexible, curved or twisted solar fabrics. More information and high-resolution images are online at http://www.science.psu.edu/news-and-events/2012-news/Badding12-2012. The information is published in the early online edition of the journal Advanced Materials.

BioChip may make diagnosis of leukemia and HIV faster, cheaper

5/30/12

Inexpensive, portable devices that can rapidly screen cells for leukemia or HIV may soon be possible thanks to a chip that can produce three-dimensional focusing of a stream of cells, according to researchers. Tony Jun Huang, associate professor of engineering science and mechanics at Penn State, and his colleagues designed a mass-producible device that can focus particles or cells in a single stream and performs three different optical assessments for each cell. They believe the device represents a major step toward low-cost flow cytometry chips for clinical diagnosis in hospitals, clinics and in the field.

Today's high-speed fiber-optic communications marry electronics and optics -- requiring semiconductor chips to convert light and optical fibers to carry the signal. But that technological merger can be cumbersome and inefficient. What if optical fibers could have the electronics built right in? That's the promise of new crystalline materials developed by an international team of researchers led by John Badding, a professor of chemistry at Penn State.

The news of science usually concerns what results a scientist has achieved, not how he [or she] has found them. . . . Yet, scientific progress continues to depend on the invention and refinement of tools and techniques. —Joshua Lederberg (1986)

"Just take a pair of goggles and go in," chemist Andrew Ewing said, as I stood before graduate student Jody Mesaros's lab.
