It has been widely reported that as water contacts hydrophobic materials such as air or hydrocarbons (liquid or solid), the interfaces acquire a negative charge. It is not entirely clear whether this occurs due to the nature of water, or…

The inductance of spintronic devices that transport charge neutral spin currents is discussed. It is known that in a media that contains charge neutral spins, a time-varying electric field induces a spin current. We show that since the spin…
