Rising temperatures are curbing ocean's capacity to store carbon
Jul 06, 2017
If there is anywhere for carbon dioxide to disappear in large quantities from the atmosphere, it is into the Earth's oceans. There, huge populations of plankton can soak up carbon dioxide from surface waters and gobble it ...
Splitting water for the cost of a nickel
Jul 03, 2017
A technique to create a material for cost-effective water electrolysis uses a simple chemical method for preparing nickel-based anodes to improve the oxygen-evolution reaction. Efficiency gains like this one developed by ...
