Smaller, stronger magnets could improve devices that harness the fusion power of the sun and stars

PPPL researchers have found a way to build powerful magnets smaller than before, aiding the design and construction of machines that could help the world harness the power of the sun to create electricity without producing greenhouse gases that contribute to climate change.

Joined nano-triangles pave the way to magnetic carbon materials

Graphene triangles with an edge length of only a few atoms behave like peculiar quantum magnets. When two of these nano-triangles are joined, a “quantum entanglement” of their magnetic moments takes place: the structure becomes antiferromagnetic. This could be a breakthrough for future magnetic materials, and another step towards spintronics. An international group led by Empa researchers recently published the results in the journal “Angewandte Chemie”.

How a Magnet Could Help Boost Understanding of Superconductivity

Physicists have unraveled a mystery behind the strange behavior of electrons in a ferromagnet, a finding that could eventually help develop high temperature superconductivity. A Rutgers co-authored study of the unusual ferromagnetic material appears in the journal Nature.

How Planets May Form After Dust Sticks Together

Scientists may have figured out how dust particles can stick together to form planets, according to a Rutgers co-authored study that may also help to improve industrial processes. In homes, adhesion on contact can cause fine particles to form dust bunnies. Similarly in outer space, adhesion causes dust particles to stick together. Large particles, however, can combine due to gravity – an essential process in forming asteroids and planets. But between these two extremes, how aggregates grow has largely been a mystery until now.
