The Lead

Lengthening the life of high-capacity silicon electrodes in rechargeable lithium batteries

December 2, 2014 4:14 pm | by Mary Beckman, Pacific Northwest National Laboratory | News | Comments

A new study will help researchers create longer-lasting, higher-capacity lithium rechargeable batteries, which are commonly used in consumer electronics. In a study published in ACS Nano, researchers showed how a coating that makes high-capacity silicon electrodes more durable could lead to a replacement for lower-capacity graphite electrodes.

Civil engineers find savings where the rubber meets the road

May 23, 2012 3:44 am | by Denise Brehm, Civil and Environmental Engineering | News | Comments

A new study by civil engineers at Massachusetts Institute of Technology shows that using stiffer pavements on the nation's roads could reduce vehicle fuel consumption by as much as 3%—a savings that could add up to 273 million barrels of crude oil per year, or $15.6 billion at today's oil prices. This would result in an accompanying annual decrease in carbon dioxide emissions of 46.5 million metric tons.

Gumby-like flexible robot crawls in tight spaces

December 1, 2011 5:12 am | by Alicia Chang, AP Science Writer | News | Comments

The Harvard University laboratory of chemist George M. Whitesides, R&D Magazine ’s 2007 Scientist of the Year, has produced a new type of flexible robot that calls to mind the clay animation character Gumby. It can wiggle and squirm through tight spaces much like the squid and starfish that inspired researchers to design it.

Making materials to order

May 26, 2011 4:01 am | by David L. Chandler, MIT News Office | News | Comments

A team of researchers at MIT has found a way to make complex composite materials whose attributes can be fine-tuned to give various desirable combinations of properties such as stiffness, strength, resistance to impacts, and energy dissipation.

Russian dandelions could be new source for rubber

May 11, 2011 5:51 am | by R&D Editors | News | Comments

As a raw material, petroleum is risky because its pricing is so volatile. By domesticating a Russian variety of dandelion and using the milky-white substance that seeps from its roots, researchers from Ford and Ohio State University believe they can create a new source of natural rubber for cupholders, floor mats, and interior trim in its cars.
