Mix and Match for Lightweight Autos

Contributing Editor Bruce Morey

9/1/2014

It is common sense—a vehicle that weighs less requires less fuel to move it. A number of studies show that reducing the mass of a vehicle by 10% results in anywhere from 4.5 to 6% better fuel economy—well worth the effort. The dilemma for automakers is that mass reduction needs to happen without compromising safety, NVH, styling, or size. Full Article

They Don’t Make ‘Em Like They Used To



Executive Editor James D. Sawyer

9/1/2014

A new era has dawned in motorized vehicle manufacturing. Until recently the dominant trend has been the implementation of lean manufacturing and continuous improvement processes to make automotive production more efficient. The new trend also stresses efficiency, but now there is a sharp focus on fuel efficiency driven by government regulation. Full Article

TechFront: New Laser-Like Polariton Beams Show Promise for Electronics, Medical Uses



Edited by Senior Editors Patrick Waurzyniak and Ellen Kehoe

9/1/2014

Researchers at the University of Michigan (Ann Arbor, MI) have developed a new laser-like beam, called a polariton, that is said to be the first polariton laser powered by electrical current instead of light. The invention, which technically isn’t a laser, also works at room temperature instead of at below-zero temperatures. Full Article

Tech Front: Research Team Develops New Ultralight, Ultrastiff Additive Materials



Edited by Senior Editors Patrick Waurzyniak and Ellen Kehoe

8/1/2014

A team of researchers from Lawrence Livermore National Laboratory (LLNL; Livermore, CA) and Massachusetts Institute of Technology (MIT; Cambridge, MA) has developed a new material for additive manufacturing processes that is as dense and light as an aerogel, but has 10,000 times more stiffness. This material is described in the researchers’ paper published in a June 20 article in the journal Science. Full Article

Tech Front: New Process Allows Nanofibers to Grow at Room Temperature



Edited by Senior Editors Patrick Waurzyniak and Ellen Kehoe

6/1/2014

Researchers at North Carolina State University (Raleigh, NC) have devised a safer method of growing vertically aligned carbon nanofibers (VACNF) with ambient air, rather than using toxic chemicals like ammonia at very high temperatures in a vacuum chamber. Full Article

Plastics Flow into the Medical Device Industry



Senior Editor Michael C. Anderson

5/1/2014

Although the North American medical device industry continues to grow, its players are under an extraordinary number of constraints. FDA requirements top the list, of course, controlling what, how, and from what materials a device can be made. On top of that are cost pressures brought on by international competition, safety and sustainability concerns, and, finally, manufacturability issues. This is not a field for the timid. Full Article
