Report: New catalyst could lead to cleaner energy

MIT chemists have devised a way to trap carbon dioxide and transform it into useful organic compounds, using a simple metal complex.

Retail Radeon chips still go slower than review versions

Chimpzilla's Radeon R9 290 and 290X review copies appear to be performing better than retail versions.

Nanocrystal catalyst transforms impure hydrogen into electricity

The quest to harness hydrogen as the clean-burning fuel of the future demands the perfect catalysts—nanoscale machines that enhance chemical reactions. Scientists must tweak atomic structures to achieve an optimum balance of reactivity, durability, and industrial-scale synthesis. In an emerging catalysis frontier, scientists also seek nanoparticles tolerant to carbon monoxide, a poisoning impurity in hydrogen derived from natural gas. This impure fuel—40 percent less expensive than the pure hydrogen produced from water—remains largely untapped.

New catalyst could cut cost of making hydrogen fuel

A discovery at the University of Wisconsin-Madison may represent a significant advance in the quest to create a "hydrogen economy" that would use this abundant element to store and transfer energy.

Meter-long nanotubes on the cards

Researchers have calculated that it should be perfectly possible to grow a perfect, meter-long single-walled carbon nanotube 50,000 times thinner than a human hair.

Team finds mechanism for origin of life

It's a chicken-and-egg problem that's concerned biologists for decades: how did the basic biochemicals of life appear before the biological catalysts needed to form them had come into existence?
