Purdue's self-assembled 'nanorings' could boost computer memory

Researchers at Purdue University have created tiny magnetic rings that can store information at room temperature and are self-assembled, promising a new approach to non-volatile computer memory. The nanorings' magnetic states can be switched by applying a magnetic field, paving the way for faster and more affordable computer memories.

Imaging lithium with an electron microscope

For the first time, researchers have used a transmission electron microscope to image lithium atoms, capturing an arrangement of lithium ions among cobalt and oxygen atoms in the compound lithium cobalt oxide. The One Angstrom Microscope achieved a resolution as high as 0.78 angstrom.

Model allows better understanding of groundwater contamination

A team of researchers from UC Davis has developed a simple model to predict the solubility of environmental contaminants in groundwater. The model uses hydrotalcites, layered compounds that can take up metals and other chemicals, to make predictions about contamination with chromium, carbon, iodine, and technetium isotopes.

Magnetism to its lowest terms

An international team observed ferromagnetism in one-dimensional cobalt chains, which exhibit both short- and long-range magnetic order. The chains' localized orbital magnetic moments are much larger than those in thin films or bulk crystals, opening up new possibilities for nanoscale magnetic structures.

New way to write to magnetic chips

Researchers at Cornell University have developed a method to switch the orientation of magnetic domains in thin layers, allowing for the creation of high-density computer memory chips. The effect works by passing an electric current through a 'sandwich' of cobalt and copper layers, resulting in non-parallel magnetic moments.
