BOSTON, MA - China aims to leapfrog the United States in technological development with substantial investment in nanotechnology, but whether those efforts will actually pay off is still unclear. That was the message from University of California at Santa Barbara researchers presenting their findings on the state of Chinese nanotechnology here at the AAAS annual meeting.

Richard Applebaum and Rachel Parker from the Center for Nanotechnology in Society at UCSB conducted about sixty interviews with Chinese officials to piece together a picture of the current state of Chinese nanotechnology. Applebaum set the specific research effort within the context of China's stated overarching goal to "leapfrog" the West by using a combination of learning from the West (i.e. technology transfer) and increasing domestic research capacity ("indigenous innovation" or zizhu chuangxin).

Nanotechnology research is one of four Chinese "science Megaprojects" that have the central purpose of catching the country up to US research by 2020. Still, for all the big talk, the actual government investment is not overwhelming. The researchers estimated that the Chinese government only invested $400 million from 2002 to 2007, although that investment is expected to rise considerably.

They highlighted several international partnerships related to nanotechnology including the Tsinghua-Foxconn Nanotechnology Research Center and the Zheijang-California NanoSystems Institute, but didn't go into much detail about what types of projects are being developed in those centers.

Right now, most nanotech research is being pushed by the central and regional governments with little private capital contributing to the national output. There are a lot of questions about whether or not that is a sustainable model for developing a high-tech industry, Applebaum noted. (It should also be noted, though, that some would question whether the venture capital model is sustainable either.)

It also leads to strange applications of nanotechnology in high-profile venues. Parker said that the Olympic village parking lots being constructed in Beijing will have a nanopolymer coating that will absorb exhaust. It was just an off-hand mention, but I am officially intrigued by the idea of coating our parking lots with pollution absorbing material. I can't vouch for the true environmental-safety of that solution, but I'd love to know how they're doing it. The coating could be something like this pollution absorbing concrete that uses titanium dioxide to degrade pollutants.
