A new way to cool down electronic devices, recover waste heat

Using electronic devices for too long can cause them to overheat, which might slow them down, damage their components or even make them explode or catch fire. Now, researchers reporting in ACS' Nano Letters have developed ...

Groovy key to nanotubes in 2-D

Ultrathin carbon nanotubes crystals could have wonderous uses, like converting waste heat into electricity with near-perfect efficiency, and Rice University engineers have taken a big step toward that goal.

New catalyst efficiently produces hydrogen from seawater

Seawater is one of the most abundant resources on earth, offering promise both as a source of hydrogen—desirable as a source of clean energy—and of drinking water in arid climates. But even as water-splitting technologies ...

Cleaning up 'dirty' ceramic tile production

Energy efficiency in kilns and other process stages of ceramics production are quite low and pollutants are currently emitted at unsustainable levels. But as costs for fossil fuels rise and governments impose ever tighter ...

Researchers build a quantum dot energy harvester

Over the past few years, thermoelectric generators have become the focus of a growing number of studies, due to their ability to convert waste heat into electrical energy. Quantum dots, semiconductor crystals with distinctive ...
