Amazon fires 'quicken Andean glacier melt'

Fires in the Amazon rainforest are likely to increase the rate of melting of Andean glaciers, potentially disrupting water supply for tens of millions of people, scientists said on Thursday.

Determining the activity of noble-metal-free catalyst particles

Chemists have developed a new method with which they can characterize individual noble-metal-free nanoparticle catalysts. The particles could be a cheap alternative to precious metal catalysts for obtaining hydrogen from ...

Breaking the symmetry in the quantum realm

For the first time, researchers have observed a break in a single quantum system. The observation—and how they made the observation—has potential implications for physics beyond the standard understanding of how quantum ...

Applying precious metal catalysts economically

Researchers at Ruhr-Universität Bochum and the Fritz Haber Institute Berlin have developed a new method of to conserve rare and expensive catalysts and use them sparingly. They enclosed a precious metal salt in tiny micelles, ...

Monitoring the lifecycle of tiny catalyst nanoparticles

Nanoparticles can be used in many ways as catalysts. To be able to tailor them in such a way that they can catalyse certain reactions selectively and efficiently, researchers need to determine the properties of single particles ...

Study looks to iron from microbes for climate help

Distributing iron particles produced by bacteria could "fertilize" microscopic ocean plants and ultimately lower atmospheric carbon levels, according to a new paper in Frontiers.
