Free radicals are unstable, electrically charged molecules that are highly reactive.

Electrophoresis has been used to fractionate small ions, charged organic molecules, proteins, and DNA.

If the surface is hydrophilic, it will allow water and charged molecules to pass through.

It uses beams of ions - electrically charged atoms or molecules - for propulsion.

As protons are charged molecules, their import or export could disrupt the membrane potential of the cell (14).

It works by ionizing chemical compounds to make electrically charged molecules or molecule pieces and measuring their mass-to-charge ratios.

Plasma is a kind of high-temperature gas, in which electrons have been stripped away to leave positively charged atoms or molecules.

In the Kennelly-Heaviside layer neutral molecules are split into electrons and positively charged molecules.

Other ions (electrically charged atoms or molecules) also help scientists reconstruct atmospheric circulation patterns.

Ion thrusters use beams of ions (electrically charged atoms or molecules) to create thrust in accordance with momentum conservation.
