Qisheng Ou, a postdoctoral research scientist at the U who is originally from China, worked on research related to increasing the efficiency of ceramic filters at the Particle Technology Lab, which hosts researchers from around the world.

The solar-powered air purification tower rises 200 feet out of a cluster of high-rises in China - a soaring symbol of new possibilities for its inventor, University of Minnesota engineering professor David Pui.

Pui hopes the technology will save some of the millions of lives claimed by air pollution each year. And with a new university startup company and interest from Chinese real estate developers, he sees a chance to bring the university a higher profile.
