United Nations weapons inspectors could have an easier time in the future locating nuclear materials. Researchers at the University of Nebraska-Lincoln developed a fingertip-sized neutron detection device built around a boroncarbide semiconductor diode. The highly sensitive device can detect neutrons emitted by materials that fuel nuclear weapons. "This is a leapfrog technology in neutron detection," said Peter Dowben, UNL physicist who first fabricated a boron carbide semiconductor. Using Dowben's semiconductor, the research team built a detector about the size of one LEGO® block, which the researchers say is more efficient, lighter, and tougher than existing detectors. It can be powered with small batteries or even solar cells and can withstand corrosion and extremely high temperatures, says Brian Robertson, associate professor of mechanical engineering at UNL. The device could also be used to monitor nuclear weapons storage and other national security applications. Patents on the semiconductor process and the detector are pending.

BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
Researchers have been developing a number of nano- and micro-scale technologies that can be used for implantable medical technology for the treatment of disease, diagnostics, prevention, and other health-related applications.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
