Highly porous carbon foam structures bonded with polymers such as polypropylene replace lead plates in typical vehicle batteries in a novel materials’ solution to problems with battery life and weight. The innovation comes from a company called Firefly Energy, using technology developed in the R&D Labs at Caterpillar, which was looking for a better battery for its vehicles. In the invention, carbon-graphite foam “grids” are loaded with lead oxides. The foam structure, creates huge surface-area advantages over conventional lead acid grid structures. Active material utilization levels go from the historical 20-50 percent up into the range of 70-90 percent as well as enhanced fast-recharge capability and greater high-rate / low-temperature discharge times, according to Firefly. Costs to produce energy will be higher than conventional lead acid batteries, but below other new technologies, such as lithium batteries. Firefly hopes the approach will be competitive for electric vehicles under development. North Star Battery will produce prototypes for possible use by the US Army.
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
