GAPowders Inc. has entered the growing market for neodymium iron boron (NdFeB) magnetic powder with a "breakthrough production technology that promises a new type of magnetic material with improved properties and lower cost." The company, a spin-off from DOE's Idaho National Engineering and Environmental Laboratory (INEEL), was formed by two of the researchers that helped develop the atomization process, along with an assist from Ames Laboratory. It essentially involves spraying molten alloy to create microscopic droplets that quickly cool into fine, spherical powders. "Atomized spherical powder flows and packs better than powder produced by crushing melt-spun flakes," says Charlie Sellers, one of the company's co-founders. "It forms higher density bonded magnets and has better high-temperature stability during magnet manufacture." Sellers sees the powders playing an increasingly important role in the production of miniature motors and actuators for everything from computer peripherals to camcorders. GAPowder has entered a strategic relationship with Magnequench International Inc. to produce the new powders. E-mail email@example.com.
During a teardown of the iPad Air and Microsoft Surface Pro 3 at the Medical Design & Manufacturing Show in Schaumburg, Ill., an engineer showed this "inflammatory" video about the dangers of maliciously mishandling lithium-ion batteries.
Science fiction author Isaac Asimov may have the best rules for effective brainstorming and creativity. His never-before-published essay, "On Creativity," recently made it to the Web pages of MIT Technology Review.
Much has been made over the potentially dangerous flammability of lithium-ion batteries after major companies like Boeing, Sony, and Tesla have grappled with well-publicized battery fires. Researchers at Stanford University may have come up with a solution to this problem with a smart sensor for lithium-ion batteries that provides a warning if the battery is about to overheat or catch fire.
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.
