'Yolk-shell' design leads to world-record battery performance

(Phys.org)—SLAC and Stanford scientists have set a world record for energy storage, using a clever "yolk-shell" design to store five times more energy in the sulfur cathode of a rechargeable lithium-ion battery than is ...

How sulfur helped make Earth habitable before the rise of oxygen

Mapping the bonds and vibrational modes of molecules containing sulfur isotopes is helping to shed light on the chemical reactions that took place in Earth's atmosphere during the Archean era, before the atmosphere became ...

Improving China's acid rain control strategy

Scientists are reporting the first evidence that China's sharp focus on reducing widespread damage to soil by acid rain by restricting sulfur dioxide air pollution may have an unexpected consequence: Gains from that pollution ...

NASA simulator helps to shed light on mysteries of solar system

Even in our cosmic backyard, the solar system, many questions remain open. On Venus there are formations similar to volcanoes, but it is not known if they are active. The surface of Mars suggests that there was once a vast ...

US power plant emissions down, study finds

Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication ...
