To take the advantage of good conductivity and network structure of Ni , the NiSe@MoSe2 is prepared by transforming Ni into NiSe and growing a layer of MoSe2 on the outside. In theory, the NiSe network can help to form conduction network and generate conduction loss, and causes dipole polarization loss. Additionally, the MoSe2 …

A magnetic moment is a vector quantity, with a magnitude and a direction. An electron has an electron magnetic dipole moment, generated by the electron's intrinsic spin property, making it an electric charge in motion. There are many different magnetic behavior including paramagnetism, diamagnetism, and ferromagnetism.

Substances containing unpaired electrons are usually paramagnetic. In the presence of a magnetic field the spins of the unpaired electrons are aligned and the substance is attracted by the magnetic field. Since Mn 2 O 3 has a high spin d 4 electron configuration, it is more strongly attracted by the magnet than MnO 2, with a d 3 electron ...

SLC30A10: A novel manganese transporter. Homozygous mutations in SLC30A10 cause familial parkinsonism associated with manganese (Mn) retention. We recently identified SLC30A10 to be a cell surface-localized Mn efflux transporter and demonstrated that parkinsonism-causing mutations block its intracellular trafficking and efflux function.

Magnetism in manganese oxide. At low temperatures, the magnetic moments, or electron spins, of neighboring Mn ions spontaneously line up in an ordered, alternating up-down-up-down pattern. As the temperature is increased, the magnetic moments start to vibrate and become less ordered. Above a critical temperature of 118 Kelvin, the long-range ...
