Cooling is a constant design challenge. To meet that challenge, researchers at Bell Labs/Lucent are experimenting with a nanostructured surface that reduces viscous drag on cooling fluid. The intention is to use billions of silicon posts to aid in transferring heat from the silicon surface to the liquid coolant. Each post has a water-repellent, Teflonlike surface, so fluids flow without wetting. When researchers apply a small electric current to the posts, the droplets on the surface slick down and wet the surface. This technology allows researchers to study the details of fluid flow and heat transfer across such superhydrophobic surfaces. The nanograss also provides a tenfold increase in the effective surface area of a flat silicon surface, which also facilitates heat transfer.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
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.
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
