Ion engines can make much more efficient use of propellant than existing chemical rockets.

Skin conductance, also known as galvanic skin response (GSR), electrodermal response (EDR), psychogalvanic reflex (PGR), skin conductance response (SCR), or skin conductance level (SCL), is a method of measuring the electrical conductance of the skin, which varies depending on the state of sweat glands in the skin.

There are four commonly mentioned types of non covalent interactions hydrogen bonds, ionic bonds, van der Waals forces, and hydrophobic interactions.

The condition has been linked with genetic mutations in genes that code for certain ion channels that transport electrolytes (sodium and potassium) across cell membranes.

Well, first there are strands of magnetic field left inside, but now the superconductor doesn't like them moving around, because their movements dissipate energy, which breaks the superconductivity state.

Of the 2008 world helium total production of about 32 million kg (193 million standard cubic meters) helium per year, the largest use (about 22 of the total in 2008) is in cryogenic applications, most of which involves cooling the superconducting magnets in medical MRI scanners.

Two general classes of GABA receptor are known GABAA in which the receptor is part of a ligand gated ion channel complex, and GABAB metabotropic receptors, which are G protein coupled receptors that open or close ion channels via intermediaries (G proteins).
