Nickel is a transition metal, meaning it has valence electrons in two shells instead of one, allowing it to form several different oxidation states. About a century later, in 1751, the Swedish ...

Metals are good conductors of electricity because the valence electrons are loosely bound, so the electrons are free to flow through the material. Nickel oxide is what is called a transition metal ...

Dr. Oliver Rader investigated at BESSY II the electronic properties of nickel coated with graphene and achieved an astonishing result. They could show that the conduction electrons of the graphene ...

The energetic levels of the electrons as well as their localisation or delocalisation can be studied at the X-ray source BESSY II, which offers powerful synchrotron radiation. Copper, Nickel ...

Butler and colleagues examined a crystal in which a layer of nickel atoms was arranged in a square lattice, like a chessboard. Individual electrons have a small mass, but within this crystal, they ...
