This past June Design News co-sponsored the International Plastics Design Competition held at the National Plastics Exposition in Chicago. One entry stood in stark contrast to the tractor hoods and water-ski bodies usually on display at previous plastic design contests held by the Society of Plastics Industry.
It clearly showed that polymers have entered a brave new world. Membrane Technologies B.V. of the Netherlands showed a hollow fiber membrane, which had been cast with a new sulfonated copolymer from Kraton. Varying sulfonation levels allow ion exchange capacity of 0.4 to 2.0 milli-equivalent per gram. The ion selectivity and unique polymer architecture results in efficient salt rejection. The fibers can be used in a larger water purification or desalinization plant.
The technical complexity of the entry must have baffled the judges, who didn’t even award it some kind of honorable mention among the bevy of announced awards.
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
