Obama Adviser Praises U.Va.'s STEM Education and Research Efforts


Speaking on a visit to the University of Virginia, John Holdren, President Obama's chief science and technology adviser, said the research being done at the nation's universities is a key engine in the drive for economic recovery. 

During the tour, Holdren witnessed tools for early tumor detection in a chemistry lab studying microfluidics, the development of new nano-magnetic technology for mobile phones and laptop computers in a nanotechnology lab in Wilsdorf Hall, cutting-edge battery and low-power electronics technology in Rice Hall, and 3D fabrication printers in a mechanical engineering lab that could help bring manufacturing back to the United States.

Congratulations to all!
The conference brought together researchers, government employees, and elected officials to discuss DOD corrosion issues and practices. Yet another strong showing, the awards reflect the ongoing impact on the field by CESE.

Congratualtions to Greg Troyer

May 2, 2012 — Greg Troyer will receive his bachelor of science degree in engineering science from the University of Virginia on May 20, having spent the vast majority of his academic time away from Grounds.


He's among the first graduates of Engineers PRODUCED in Virginia, an innovative workforce development program that brings engineering education out to students in Virginia communities needing greater access to technical talent.

After he completes his degree, Troyer will work full-time for Areva, a global energy company in Lynchburg, where he will evaluate and analyze the materials used in nuclear power plants. A Lynchburg native, he has spent summers interning at Areva and worked part-time there while finishing his degree.


Graduating from U.Va. with a 4.0 grade-point average, he has received the Materials Science and Engineering Distinguished Undergraduate Award. Troyer, 24, said he was working in construction, but knew that wasn't a long-term proposition. "I've always been interested in math and science, which fall together into engineering as a practical application," he said.


While a student at Central Virginia Community College, he became acquainted with the PRODUCED program and, after earning his associate's degree with a 4.0 GPA, enrolled at U.Va.

"All of my classes have been taken electronically," he said. "Online learning sounds terrible to some people, but when we're taking classes at U.Va., we're sitting in on real, live classes. There's a professor lecturing to 30 or 100 students and we have video feed into the classroom, desktop sharing so I can see the PowerPoint the class sees, and two-way audio so I can ask a question in real time.


"All I need is a reliable Internet connection. I take classes from my desk at work, or from my desk at home. I prefer this type of setting and the flexibility it gives me."


Working part-time while attending U.Va. was a good combination for him, he said. "From a professional development standpoint, I learn just as much or more from being at work as I do at school," he said. "This benefits me because I can ask informed questions in the classroom to help cement something I see at work. It is also beneficial to U.Va. because I'm in the classroom making the professor think about how what they are teaching is being applied in real life."

MSE SEMINAR SERIES: Martin Wenderoth Talk Title: "Scanning Tunneling Microscopy Playing with electric fields on the atomic scale"

 MSE SEMINAR SERIES: Martin Wenderoth Talk Title: "Scanning Tunneling Microscopy Playing with electric fields on the atomic scale"

WhereWilsdorf 101 (map)
DescriptionThe challenge of the ever shrinking semiconductor devices has been a subject of discussion for decades. In devices below a critical size doping or transport properties cannot be described in a homogeneous model anymore. Using a low-temperature scanning tunnelling microscope (STM) operating at 5 Kelvin we have studied the impact of the electric field on single dopant atoms in GaAs in different configurations. The discrete nature of the charge of a dopant atom in combination with the long range Coulomb field results in a complex electrostatic potential landscape. Using the voltage between tip and semiconductor across the vacuum barrier to manipulate the potential landscape, we are able to control and to visualize the charge state of individual and multi donor systems near the GaAs (110) surface. Using an STM extended to a three-terminal geometry we have studied single acceptor atoms exposed to an “in plane” electric field of a biased p-i-n diode. High-resolution scanning tunnelling spectroscopy measurements show that the resonance channel induced by the acceptor can be switched on and off. In a second type of experiment we have used scanning tunnelling potentiometry to map local transport field near localized scattering centers in a quasi 2D electron gas down to the nm scale.

U.Va’s NExT Club heads to DC for NNI booth

February 18, 2012

U Va’s Nano and Emerging Technologies (NExT) Club teamed up with the National Nanotechnology Initiative (NNI) to present nanotechnology demonstrations during the Discover Engineering Family Day at the National Building Museum in Washington, DC. The NNI booth was one of 30 exhibits exploring all aspects of engineering as part of Engineers Week. The event was sponsored by National Engineers Week Foundation, IEEE-USA, Northrop Grumman Foundation and ASME. NextTech Junior Chapter Member and nanoSTAR Student Programs Coordinator also lent a hand to explain nanotechnology to the event’s estimated 10,000+ attendees.
