First detailed electronic study of new nickelate superconductor

The discovery last year of the first nickel oxide material that shows clear signs of superconductivity set off a race by scientists around the world to find out more. The crystal structure of the material is similar to copper ...

Surprising electronic disorder in a copper oxide-based ceramic

Cuprates, a class of copper-oxide ceramics that share a common building block of copper and oxygen atoms in a flat square lattice, have been studied for their ability to be superconducting at relatively high temperatures. ...

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 ...

Isolation of Fe(IV) decamethylferrocene salts

(Phys.org)—Ferrocene is the model compound that students often learn when they are introduced to organometallic chemistry. It has an iron center that is coordinated to the π electrons in two cyclopentadienyl rings. (C5H5- ...

Silicon oxide memories transcend a hurdle

A Rice University laboratory pioneering memory devices that use cheap, plentiful silicon oxide to store data has pushed them a step further with chips that show the technology's practicality.
