Materials Spotlighted at Design & Manufacturing Show
Engineering Materials 8/29/2013 3 comments The choices of metals, plastics, coatings, and adhesives has never been broader, and new ones are becoming available at a rapid rate. Some of this variety is reflected at the upcoming Design and Manufacturing Midwest Show.
Jobs Was a Genius; the Movie Not So Much
Blog 8/28/2013 16 comments The movie's producers tried to sum up Jobs's entire professional career in two hours, too many significant parts were left out, and the movie did not accurately show the genius that Jobs was.
3D Printing With Iron & Tungsten
Engineering Materials 8/26/2013 7 comments The range of metals that can be 3D printed is increasing. ExOne has added iron infiltrated with bronze, and bonded tungsten, to the range of metal and ceramic powders that can be used with its multi-material M-Flex machines.
Slideshow: Robots Get More Thin-Skinned
Engineering Materials 8/22/2013 23 comments Robots may be getting more sensitive, due to a breakthrough by engineers at the University of California, Berkeley. An electronic skin made of a sensor network mounted on a substrate of flexible plastic reacts to touch by lighting up.
Researchers Develop Another Potential Battery for Renewable Energy Storage
Blog 8/20/2013 20 comments A research team led by Yi Cui, an associate professor in the Department of Materials Science and Engineering at Stanford, has developed a new lithium-polysulfide flow battery with an energy density of between 170 Wh/kg and 190 Wh/L and a lifespan of up to 2,500 cycles -- results that are high comparatively for similar batteries being designed for renewables.
Top Reasons for the US to Return to Space
Guest Blogs 8/14/2013 14 comments Over the years, government and popular support for further space exploration has dwindled, despite its many benefits. So, we've made a list of the top reasons we should continue to explore the outer depths, "to boldly go where no man has gone before."
Video: Evolving 3D Printing
CAD/CAM Corner 8/12/2013 11 comments Artists are using the 3D printing craze to create new types of art, and MIT researchers are working on programmable materials for 4D printing.
DuPont Pushes for a 50%-Plus Renewable Plastics Line
Engineering Materials 8/9/2013 13 comments DuPont says its performance plastics line will contain more than half renewable materials within 15 years, and that all of its medium- to long-term research in engineering plastic feedstocks is based on the need to move to non-food based sources.
MIT 3D Prints Tough, Bone-Like Composite
Engineering Materials 8/8/2013 6 comments A team at MIT has 3D-printed bone-like composite materials on the Objet Connex500 multi-material printer. One was more than 20 times as tough as its constituent materials alone.
How to Make Intelligent Carbon-Fiber Composites
Engineering Materials 8/7/2013 6 comments German researchers have demonstrated the ability to embed RFID tags with ultra-thin antennas inside carbon-fiber-reinforced composite components such as aircraft wings. The technique is also being investigated for composite structural health monitoring.
Update: Corning's Paper-Thin, Flexible Glass
Engineering Materials 8/1/2013 11 comments Corning's super-thin, 100-micron Willow Glass can be adapted to high-volume, low-cost, roll-to-roll manufacturing processes not previously possible with glass. Corning is helping customers retrofit or build new lines to integrate the material into manufacturing.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
