New devices based on rust could reduce excess heat in computers

Scientists have succeeded in observing the first long-distance transfer of information in a magnetic group of materials known as antiferromagnets. These materials make it possible to achieve computing speeds much faster than ...

Rare earth orthoferrite LnFeO3 nanoparticles for bioimaging

Magnetic resonance imaging (MRI) has emerged as one of the most powerful clinical imaging tools because of its superb spatial resolution and soft tissue contrast, especially when using contrast agents. In the European Journal ...

Hydrogen from water in iron nanotruss structures

Swedish researchers have discovered a new and efficient way to use electrocatalysis to produce hydrogen gas from water. Instead of using expensive and difficult-to-obtain platinum electrodes, the new method uses electrodes ...

Building bridges with water molecules

A team at TU Wien now has the proof behind the speculations that water molecules can form complex bridge-like structures when they accumulate on mineral surfaces.

Tuning in to magnetic ink

A new ink containing iron-oxide nanoparticles can be turned into fully printed and versatile components for cellular networks.

Tiny engine powered by demixing fluid

An international team of researchers has developed a tiny, liquid-based engine powered by a demixing fluid. In their paper published in the journal Physical Review Letters, the group describes their little engine and possible ...

Which came first: Complex life or high atmospheric oxygen?

We and all other animals wouldn't be here today if our planet didn't have a lot of oxygen in its atmosphere and oceans. But how crucial were high oxygen levels to the transition from simple, single-celled life forms to the ...

Wheat gets boost from purified nanotubes

The introduction of purified carbon nanotubes appears to have a beneficial effect on the early growth of wheatgrass, according to Rice University scientists. But in the presence of contaminants, those same nanotubes could ...
