One of the weirder materials developments from the economic slowdown is a shortage of sawdust. Prices are up some 25 percent in the past two years, if you can get it. Sawdust is not normally considered an engineering material, but it’s often used as an additive for plastic compounds that cover steering wheels and dashboards. Demand for wood plastic composites has grown dramatically and is close to a billion pounds this year, mostly for construction applications. Composites are typically close to half wood flour and high-density polyethylene, with a smattering of other additives such as stabilizers and pigments. Wood plastic composites are favored for automotive applications because they have a lower specific gravity than compounds made with other inorganic materials. They also give an “organic” look and are considered environmentally friendly. The new economics, however, surely will slow penetration. The reason is the slowdown in house construction, which is slowing timber operations. The weakness of the US dollar versus the Canadian dollar also is having an impact.
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
