Do you keep music or tax files on compact discs you bought at a big box store? Well any money you saved by buying cheap CDs could be lost in a hurry. There are some reports that cheap CDs only last two years or so. Cutting corners on materials’ quality exponentially increases the potential for damage from poor handling or storage practices. You have a couple options: 1) Buy high-quality CDs and be careful when handling or 2) Practice extremely careful storage and handling with special technology.
One way to protected CDs is to pay a quarter for a special plastic sleeve developed by Bell Labs. The sleeve features a semiconductive plastic film or sheet. The base polymer is typically polyethylene or polyester that is chemically reacted with conductive copper and other ingredients to form a covalently bonded, homogeneous structure. If someone walks on a carpet and then touches a CD, they can discharge electricity that can locally oxidize a region of the aluminum layer embedded in the CD. The oxidized aluminum will no longer reflect a CD drive’s laser light properly, so all data recorded in the affected area ceases to be readable. Bell Labs licensed the idea to a company called Intercept Technology.
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
