If C has a positive charge, the negative charges in the metal are attracted to it and move to the inner surface of the container, while the positive charges are repelled and move to the outside surface. If C has a negative charge, the charges have opposite polarity. Since the container was originally uncharged, the two regions have equal and ...
The intense blue color of Prussian blue is a consequence of an intervalence charge transfer band. In chemistry, intervalence charge transfer, often abbreviated IVCT or even IT, is a type of charge-transfer band that is associated with mixed valence compounds. It is most common for systems with two metal sites differing only in oxidation state.
It was first proposed by Niels Bjerrum in 1952 in order to explain the electrical polarization of ice in an electric field. [2] A hydrogen bond normally has one proton , but a hydrogen bond with a Bjerrum defect will have either two protons (D defect, from "doppel" in German, meaning "double" [ 3 ] ) or no proton (L defect, from "leer" in ...
The concentration of vanadium in the blood of ascidian tunicates is as much as ten million times higher [specify] [102] [103] than the surrounding seawater, which normally contains 1 to 2 μg/L. [104] [105] The function of this vanadium concentration system and these vanadium-bearing proteins is still unknown, but the vanadocytes are later ...

Vanadium compounds are compounds formed by the element vanadium (V). The chemistry of vanadium is noteworthy for the accessibility of the four adjacent oxidation states 2–5, whereas the chemistry of the other group 5 elements , niobium and tantalum , are somewhat more limited to the +5 oxidation state.

The vanadium redox battery (VRB), also known as the vanadium flow battery (VFB) or vanadium redox flow battery (VRFB), is a type of rechargeable flow battery. It employs vanadium ions as charge carriers . [ 6 ]
Charge-transfer insulators are a class of materials predicted to be conductors following conventional band theory, but which are in fact insulators due to a charge-transfer process. Unlike in Mott insulators , where the insulating properties arise from electrons hopping between unit cells, the electrons in charge-transfer insulators move ...
