Rust – iron oxide – is a poor conductor of electricity, which is why an electronic device with a rusted battery usually won't work. Despite this poor conductivity, an electron transferred to a ...

Conventional lithium-ion batteries contain problematic substances such as nickel and cobalt, and the solvents used to coat the electrode materials are also toxic. Conventional lithium-ion batteries ...

When we think of rust—iron oxide—we usually refer to its negative effects in terms of corrosion and material degradation. But rust does have its uses: It can function in some cases as a protective ...

Iron oxide (chemical formula Fe 2 O 3) is a main constituent of rust. Each iron atom acts as a tiny compass, but this particular form of Fe 2 O 3 is not magnetic in the ordinary sense of attracting ...

(Nanowerk News) Using a state-of-the-art microscopy technique, experimenters at the National Institute of Standards and Technology (NIST) and their colleagues have witnessed a slow-motion, ...

Rust is a common problem on bridges, cars, and other metal structures, but new research shows that when it’s combined with saltwater, it can also be a source of electricity. New research conducted by ...

Using iron isotopes and atom probe tomography, or APT, they traced these oxidation-reduction reactions to create the first 3D "atomic maps" of the re-arrangement of different iron atoms in a small ...
