Look for increasing development of bioplastics for the medical market. In one of the more interesting announcements at last month’s MD&M show in Anaheim, CA, Arkema said it is in the process of developing a sustainable, bio-based acrylic polymer for medical devices that will feature extremely high impact strength. Introduction is scheduled for mid-2011.
No details are currently available, but it’s expected the compound will be an acrylic blended with polylactic acid (PLA), possibly in the 20 to 40 percent range. That route would be no surprise because Arkema is a major developer of additives that boost performance (particularly impact resistance) o of PLA, which is a thermoplastic aliphatic polyester derived from corn starch, sugar cane, and other crops, even tapioca.
Arkema scientists are looking for feedstocks that could produce acrylic in place of methyl methacrylate (MMA), which is in very short supply. Demand for MMA is rising, but supply is declining due to plant closings. Major chemical producers, such as Dow, are putting less emphasis on bulk petrochemicals. Climate change is also an issue in the biomonomer development, but not the key driver.
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
