Researchers combine disciplines, computational programs to determine atomic structure

27-Aug-2015

A team from the University of Illinois at Urbana-Champaign and Indiana University combined two techniques to determine the structure of cyanostar, a new abiological molecule that captures unwanted negative ions in solutions. When Semin Lee, a chemist and Beckman Institute postdoctoral fellow at ...

From fluids to flames, research on the space station is helping advance technology

21-Aug-2015

A study explored the finer points of fluid dynamics, something that is experienced across the planet, but cannot quite be studied as carefully on Earth. A phenomenon called Marangoni convection is one of the fundamental principles of liquid motion and is revealed much more clearly in ...

Researcher uses vibrations to identify materials' composition

Hybrid photonic-nanomechanical force microscopy (HPFM) brings greater spatial resolution

12-Aug-2015

A researcher at the University of Central Florida has developed a new method for identifying materials' unique chemical "fingerprints" and mapping their chemical properties at a much higher spatial resolution than ever before. It's a discovery that could have promising implications for fields as ...

Making a better nitrate test kit

11-Aug-2015

The dull black plastic of the device on Joshua Pearce's desk belies its usefulness. Pearce picks up the box, which has a switch on the side and a small opening on top. A handful of vials sit in a bag nearby, and each would fit snugly in the opening. The set-up seems generic, even bland, except ...

A most singular nano-imaging technique

Berkeley Lab's SINGLE provides images of individual nanoparticles in solution

20-Jul-2015

Just as proteins are one of the basic building blocks of biology, nanoparticles can serve as the basic building blocks for next generation materials. In keeping with this parallel between biology and nanotechnology, a proven technique for determining the three dimensional structures of individual ...
