Designing a dysprosium-free high-performance neodymium magnet

Fujitsu Limited today announced that, in joint research with the National Institute for Materials Science (NIMS) and Fujitsu Laboratories Ltd., it has developed the world's largest magnetic-reversal simulator, using a mesh ...

Research simplifies recycling of rare-earth magnets

Despite their ubiquity in consumer electronics, rare-earth metals are, as their name suggests, hard to come by. Mining and purifying them is an expensive, labor-intensive and ecologically devastating process.

Simple separation process for neodymium and dysprosium

Rare-earth metals are critical components of electronic materials and permanent magnets. Recycling of consumer products is a promising source for these rare commodities. In the journal Angewandte Chemie, American scientists ...

New study shows large landmasses existed 2.7 billion years ago

A Cologne working group involving Prof. Carsten Münker and Dr. Elis Hoffmann and their student Sebastian Viehmann (working with Prof. Michael Bau from the Jacobs University Bremen) have managed for the first time to determine ...

Greenland rocks provide evidence of Earth formation process

(Phys.org)—Rocks dating back 3.4 billion years from south-west Greenland's Isua mountain range have yielded valuable information about the structure of the Earth during its earliest stages of development. In these rocks, ...

Hitachi unveils motor without 'rare earths'

Japanese high-tech firm Hitachi Wednesday unveiled an electric motor that does not use "rare earths", aiming to cut costs and reduce dependence on imports of the scarce minerals from China.

Clean energy could lead to scarce materials

As the world moves toward greater use of low-carbon and zero-carbon energy sources, a possible bottleneck looms, according to a new MIT study: the supply of certain metals needed for key clean-energy technologies.

Rare earth metals: Another challenge for the green economy?

If you follow the clean energy dialogue, then you may have encountered discussions about the role of rare earth metals at some point in the last year or two. If not, read on, because rare earths should not be a rare topic ...
