I’ve heard of several new plastics that make excellent metal replacements. But concrete? That’s a first for me. A hydrogen-rich polymer loaded with boron actually can replace concrete as neutron-shielding material in nuclear power plants or nuclear submarines. The new Quadrant EPP material is currently available in machinable 1-inch x 48-inch x 96-inch plates. Borotron HD050 is a high-density polyethylene (HDPE) enhanced with 5 percent elemental boron to provide extra shielding against neutron radiation. The combination of boron within a matrix of HDPE, a naturally hydrogen-rich material, targets nuclear shielding applications. Hydrogen-rich materials attenuate neutrons extremely well and boron has an affinity for absorbing thermalized neutrons. Potential uses include shielding for radiation therapy rooms, where the product in plate form is integrated into the wall structure. Other application areas include nuclear research centers, nuclear power plants, power generation areas in nuclear submarines, production areas for nuclear detection devices and the equipment itself, and spacecraft exposed to radiation. Borotron HD050 plate is lighter than some other neutron shielding materials such as concrete, and easier to work with in construction than other options including water. The formulation was engineered by Quadrant Engineering Plastic Products (Quadrant EPP).
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.
Researchers at the Missouri University of Science & Technology have designed a new nanoscale material that can transmit light faster than the 186,000 miles per second it usually takes to travel through air.
It has often been said that as California goes, so goes the nation. This spring, the state's wind power is setting energy generation records and solar energy generation is expected to rise sharply during the second half of 2013.
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
