"We investigated a material made of palladium, silicon and cerium," says Silke Bühler-Paschen. "We focus on the electrons located at the cerium atom and on the conduction electrons, which can ...

The electrons of the cerium atom are quantum mechanically linked to the atoms of the crystal. Actually, the Kondo effect is known from low temperature physics, close to absolute zero temperature.

Researchers at the Department of Energy's Pacific Northwest National Laboratory are helping to reduce the nation's dependence ...

On the basis of any theory of atomic structure which classifies the elements according to rare gas type, cerium and thorium should be comparable with one another, since the atoms of each are ...

Electrons have different properties - and they all can be used to create order in solid objects. This order determines the properties of the material. Experiments at the TU Vienna show: It is ...

In this case, the clathrate was used to encase atoms of cerium (atomic number 58). The magnetic properties of cerium were found to boost the thermoelectric capacity of the crystals by more than 50%.

"Understanding how molecular hydrogen interacts with ceria [cerium oxide, CeO2], however, is a big challenge, as no regular technique can 'see' the light H atom.

But single-atom catalysts tend to be unstable, especially when used in high-temperature reactions, because metal atoms don’t like being isolated, which is energetically unfavorable.

The cerium oxide sticks like a glue to the silicon dioxide and holds the individual metal atoms tightly so that they don’t wander off to find each other, clump and become ineffective. The researchers ...

Lanthanum and cerium are among the most common rare earth metals. Lanthanum is used in camera lenses and lighting. Cerium is used in catalytic converters, which reduce combustion engine emissions.
