Three ferrromagnetic liquid droplets containing iron oxide nanoparticle dispersions were shaped into cylinders using a microfluidic device, and then locked in shape by the formation of magnetic ...

Most magnets are predictable. Cool them down, and their tiny magnetic moments snap into place like disciplined soldiers. However, physicists have long suspected that, under the right conditions, ...

Scientists have produced a new route to materials with complex 'disordered' magnetic properties at the quantum level. The material, based on a framework of ruthenium, fulfils the requirements of the ...

A robot boat with a propeller made from liquid magnets could be a safer alternative than solid metal blades, which can damage wildlife. Jun Shintake at the University of Electro-Communications in ...

Lodestone, a naturally-occurring iron oxide, was the first persistently magnetic material known to humans. The Han Chinese used it for divining boards 2,200 years ago; ancient Greeks puzzled over why ...

A new route to materials with complex ‘disordered’ magnetic properties at the quantum level has been produced by scientists for the first time. The material, based on a framework of ruthenium, fulfils ...
