A sophisticated necklace can monitor food and drink intake, which could help wearers track and improve their dietary habits.

Improving energy efficiency one atom at a time

Molecular beam epitaxy is a cutting-edge technique that allows for the design and creation of completely new materials that don't exist in nature.

Robotic ocean gliders aid study of melting polar ice

Using robotic ocean gliders, researchers have now found that swirling ocean eddies, similar to atmospheric storms, play an important role in transporting warm waters to the Antarctic coast—a discovery that will help the scientific community determine how rapidly the ice is melting and, as a result, how quickly ocean levels will rise.

Carbonics revolutionizing wireless technology by employing carbon

Carbonics aims to revolutionize traditional electronics by employing earth-abundant carbon nanomaterials to vastly improve the power consumption and performance of wireless products that include next-generation smartphone and wearable devices.

Recycling old batteries into solar cells

A system proposed by researchers recycles materials from discarded car batteries — a potential source of lead pollution — into new, long-lasting solar panels.

Running on waste heat

Researchers have now created a thermoelectric generator (TEG) — a one-square-inch, quarter-inch-thick module — that turns waste heat emitted by vehicles into electricity to lend those vehicles added power.

Holey graphene bridges gap between supercapacitors and batteries

Researchers have used a special type of graphene material, called holey graphene framework because of its three-dimensional perforated structure, to advance the energy density of an electrochemical capacitor to levels equal to those of lead acid batteries.

ARB approves funding plan for low-carbon, zero-emission vehicles

The California Air Resources Board have taken two separate actions that combined will continue to support the development and deployment of advanced vehicle technologies, provide incentives for clean-cars and improve existing vehicle retirement and replacement programs.
