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.

We looked at a number of sources to determine this year's greenest cars, from KBB to automotive trade magazines to environmental organizations. These 14 cars emerged as being great at either stretching fuel or reducing carbon footprint.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
