Manipulating CNTs and nanoparticles is tricky business because so many conditions affect their behavior. Just below nanoscale, at the level of individual atoms, matter acts quite differently than it does lumped together in bulk.
Already they have devised a gas sensor using only nanoparticles of tin oxide.
Their process for producing hybrid structures is far superior to the method currently available, and their work advances understanding of how materials in the quantum world interact with those in the seen world.
Surface science cluster at UWM
My goal is to make something real, that people can see and use and that has tangible results, says Chen, who came to UWM in 2003 after a year as a post-doctoral scholar at the California Institute of Technology.
With two patents pending and funding from sources such as the National Science Foundation and the Xerox Corporation, he is well on his way.
Chen is one of a cluster of UWM scientists in engineering, chemistry and physics who conduct research into nano- and surface science. In fact, UWMs Laboratory for Surface Studies, a University of Wisconsin System Center of Excellence, brings together the work of 13 faculty who explore the structure and properties of solid surfaces and the interaction of surfaces with atoms and molecules.
The labs research encompasses topics such as thin films and laminates, spintronics, molecular wires, optical fiber sensing, and properties such as catalysis, corrosion and friction.
New materials, cool features
When it comes to size, theres tiny and then theres tiny all over. Nanostructures can be at nanoscale in either one, two or three dimensions, or any combination. The structures properties are determined by the number of dimensions at nanoscale, its shape, and the material its made
