MATERIALS:Solvay Advanced Polymers LLC’s AvaSpire® AV-700 Series is a new line of modified PEEK grades that fill the cost/performance gap between high-performance crystalline polymers (PPS, LCP and high-temperature nylon) and PEEK, an ultra-performance crystalline polymer. These proprietary PEEK-based formulations - available in unfilled, filled and wear-resistant grades - offer comparable strength and modulus, equivalent or better chemical resistance and up to a 30 percent cost reduction versus comparable PEEK grades. Targeted uses include applications in automotive, heavy-duty off-highway equipment, oil and gas recovery, semiconductors and chemical processing. The flagship material is AvaSpire® AV-722 BG 20, an unfilled resin that is the basis for most of the AV-700 series formulations. The line also consists of AvaSpire® AV-722 CF30, a 30 percent carbon fiber-reinforced grade, and three wear-resistant grades (AV-742 SL30, AV-722 SL30 and AV-755 SL45). Another grade, 40 percent glass-filled AvaSpire® AV-750 GF40, has been previously available.
In this new Design News feature, "How it Works," we’re starting off by examining the inner workings of the electronic cigarette. While e-cigarettes seemed like a gimmick just two or three years ago, they’re catching fire -- so to speak. Sales topped $1 billion last year and are set to hit $10 billion by 2017. Cigarette companies are fighting back by buying up e-cigarette manufacturers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
