Tech Front: New Carbon Nanotubes May Boost Battery Life

Edited by Senior Editors Patrick Waurzyniak and Ellen Kehoe

3/1/2015

A team of researchers at the University of Wisconsin have discovered high-performing carbon nanotubes that may lead to the development of improved battery life for flexible electronics and also for military and industrial applications. The research team, led by materials science Associate Professor Michael Arnold and Professor Padma Gopalan, recently released their results in a paper published in the journal ACS Nano. Full Article

Part of the Hole Story



Senior Editor Ellen Kehoe

2/26/2015

It couldn’t have been long after the first tools were hacked into shape that the first holes were made in some rock or tree. Fast forward many centuries and the first machine tool used by mechanically minded folks is likely a drill press. Everyone feels like an expert after making a perfect hole in something, but precision holemaking involves “many factors that must be considered regardless of how simple making holes might seem,” says the author of SME Technical Paper TP62PUB6.

Lightweighting Heavy on History



Senior Editor Ellen Kehoe

2/23/2015

Maybe the desire to lose weight doesn’t go back as far as Atlas in Greek mythology, but for decades materials experts have sought lighter weight with strength and economy in the more well-known applications of autos and airplanes as well as in such products as metal cans and bicycles. Full Article

Variations of Waterjet: Robotic and Abrasive



Senior Editor Ellen Kehoe

2/12/2015

No sooner had waterjet cutting gone mainstream did someone think of adding an abrasive to the water flow and integrating a robot into the system. From SME Technical Paper TP85PUB248: "High pressure waterjet machines capable of cutting relatively soft materials such as paper, cloth, wood, and fiberglass can now cut ceramics, metal composites, and tough metals such as Inconel and titanium because of a recent design innovation which induces abrasive grit into the water jet."

Tracing the Flow of Waterjet Processes



Senior Editor Ellen Kehoe

2/10/2015

What’s able to cut steel, disposable diapers, composites, newsprint, titanium, ceramic tile, wood, cloth and even cake? With apologies to Superman, it’s waterjet, of course. Although “a modern waterjet system can slit a mile of newsprint in a minute using only a cup of water,” the history of using water for washing away material goes way back. Full Article
