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.
By experimenting with the photovoltaic reaction in solar cells, researchers at MIT have made a breakthrough in energy efficiency that significantly pushes the boundaries of current commercial cells on the market.
In a world that's going green, industrial operations have a problem: Their processes involve materials that are potentially toxic, flammable, corrosive, or reactive. If improperly managed, this can precipitate dangerous health and environmental consequences.
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
