Scientists refine formula for nanotube types

September 17, 2014 9:52 am | by Mike Williams, Rice Univ. | Videos | Comments

Many a great idea springs from talks over a cup of coffee. But it’s rare and wonderful when a revelation comes from the cup itself. Rice Univ. theoretical physicist Boris Yakobson, acting upon sudden inspiration at a meeting last year, obtained a couple of spare coffee cups from a server and a pair of scissors and proceeded to lay out—science fair-style—an idea that could have far-reaching implications for the nanotechnology industry.

Novel capability enables first test of real turbine engine conditions

September 17, 2014 7:46 am | by Tona Kunz, Argonne National Laboratory | News | Comments

Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a partnership between Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs.
