Heat pipes developed at Los Alamos National Lab efficiently transport large quantities of heat in numerous applications, including space flight. Fluid within the heat pipe vaporizes at the hot end; condenses as it reaches the other, slightly cooler end; and returns to the hot end through a capillary wick to repeat the process. "It's a little like a laboratory in a tube," says Bob Reid, a mechanical engineer in Los Alamos Engineering Science and Applications Div. He believes the heat pipe technology is destined to be an integral part of space-age travel. NASA's Marshall Space Flight Center (Huntsville, AL) is working with Los Alamos developing heat pipes for use in nuclear reactors to produce propulsion and generate electricity for spacecraft journeying through the solar system. Los Alamos also worked with NASA Langely Research Center (Hampton, VA) designing a futuristic hypersonic aerospace plane that would complete most of its flight in low-Earth orbit. Heat pipes cool the leading edges of the wings and engine ducts. Heat pipes also flew aboard the Space Shuttle Endeavor. Additional applications include miniature versions of the heat pipe that cool the chips inside laptop computers and geostationary communications satellites. Heat pipes vary greatly in size, depending upon their particular use. Some are the size of hypodermic needles. Other versions stretch to 24 ft. The heat pipes use lithium, a soft chemical that is the lightest known metal. Visit the Los Alamos web site, www.lanl.gov .
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
