Broader Use of Ceramic Bearings
One-third less thermal expansion; half the thermal conductivity; lighter weight and non-corrosive. Lots to like about ceramic bearings, if your app can live with the brittleness. When you spec bearings for tough duty equipment like medical devices, cryogenic pumps, semiconductors, and food processing machinery, consider miniature ceramic and hybrid ball bearings.

Whittling Weight from Wheels
The push for efficiency keeps car parts in constant redesign. Witness this new wheel bearing featuring axial splines, helping provide greater torque transmission, trimming up to 2 lbs/bearing, and allowing easier mounting. Key to the design is applying axial splines onto an orbitally formed shoulder by high precision cold forming.

Charged Up About Lighter Tools
Still using NiCad rechargeables? Hurting for a tool that maintains its charge when you need it? Lithium ion batteries and an air-cooled charging system expand run time and cut recharge time by 30% for these cordless power tools. The lighter weight might ramp up productivity and prevent fatigue during drilling, sawing, or welding assignments.

Not Corny: Cellulose for BioPlastic
Automotive OEMs helped pioneer bioplastics from corn. But Mazda backed projects yielding the world's first high-heat, high strength bioplastic and polylactic acid (PLA), a plant-derived plastic used for seat fabric in its Premacy hybrid. Next comes a project to develop propylene from cellulose in plant waste or wood, for bumpers and instrument panels.

GaN Ready to Dethrone Silicon?
In a market dominated by computer automation and miniaturization, even major advances sometimes seem routine. And some discoveries shake this silicon-centric world. A transistor developed at Rensselaer Polytechnic Institute, based on use of gallium nitride (GaN), might replace silicon transistors for high power and high temperature electronics.

Coiled Pin to the Rescue
Honoring the boss' edict, you review the traditional trio of options: save on components, cut prep costs, and reduce assembly costs. Your search unearths the coiled pin fastener — a potential winner on all counts. The self-retaining fasteners absorb forces during assembly and product use. They simplify assembly by replacing multiple components.

Poly Makes It Crackless
The right coating for fasteners and other intricate hardware is sometimes elusive; finding the right flow properties for hardware in automotive engines and appliances can be even tougher. This high-impact nylon flows easily into intricate parts, yet offers sufficient bend and impact strength to survive assembly stresses and resist cracking at low temperatures.

Granddaddy of Engineering Career Challenges
Career coaches often advise: To advance in your career, you have to learn to promote yourself. Plenty hard for many. But can an entire profession of engineers heed the same advice? A trio of North America's engineering leaders think the discipline needs to do so. They say it may be engineering's biggest challenge — and curiously missing from a list published earlier this year, enumerating 14 Grand Challenges for Engineering in the 21st Century.

Space Tourism Moves in on Milestone
The commercial space travel business takes a big step toward reality late this month with ground and flight tests in the Mojave Desert. Scaled Composites' mothership is the most fuel efficient aircraft ever built, mainly because everything is constructed of lightweight carbon composite — even the control wires, an aviation first. But, the test team still has to grapple with aviation's top concern in lift-offs: weight. They've sold sufficient tickets and room to payloads to worry.
