Researchers at the Georgia Institute of Technology have developed a prototype wireless sensor capable of detecting trace amounts of a key ingredient found in many explosives. The device, which employs carbon nanotubes and is printed on paper or paper-like material using standard inkjet technology, could be deployed in large numbers to alert authorities to the presence of explosives, such as improvised explosive devices (IEDs).

New research shows how metal surfaces that lack mirror symmetry could provide a novel approach towards manufacturing pharmaceuticals. These ‘intrinsically chiral’ metal surfaces offer potential new ways to control chiral chemistry, pointing to the intriguing possibility of using heterogeneous catalysis in drug synthesis. Such surfaces could also become the basis of new biosensor technologies.

The nature of a glass is a debate that runs far deeper than whether one appears half empty or half full. For years scientists have known that the atoms and molecules in glasses arrange themselves randomly, like the non-uniform pattern of particles in a liquid. What’s puzzling, though, is that while the molecules in a glass are arranged like in a liquid, the overall structure is solid.

The human eye is as comfortable with white light generated by diode lasers as with that produced by increasingly popular light-emitting diodes (LEDs), according to tests conceived at Sandia National Laboratories.
