As a result of these collisions, the atoms in the beams would lose electrons and become positively charged ions.
The now positively charged hydrogen atoms migrate through the membrane to combine with oxygen on the air side to create water.
In an atmosphere of deuterium gas, the field generated positively charged deuteron ions and accelerated them to high energy in a beam.

It contains several electrodes, with immovable positively charged particles to attract electrons.
As the water passes through the media, the negatively charged arsenic ions are absorbed onto the surfaces of the positively charged media particles.
FORBES: "Plastic Bottle" Filters Can Help Millions Poisoned by Arsenic-Contaminated Water
Helium nuclei are positively charged and thus easier to rein in using an electric field, in order to strip them of their energy.
Those primeval life-forms use a simple type of cellular pump that pushes sodium out of the cell while pulling positively charged protons in.
In an ultracapacitor, positively charged ions gather on the surface of the negatively charged electrode and negative ions on the surface of the positive electrode.
The others are large, negatively charged molecules that attach themselves to viral particles (which are positively charged on the outside) and thus render them harmless.
The theory is that when a muon encounters a gas molecule, it can knock off an electron, leaving a positively charged ion in its wake.
These atoms are missing an electron and are thus positively charged.
The process took advantage of an electric charge differential existing between the polymer, which was positively charged, and the bacteria cells, which carried a net negative charge.
The group at CERN, called the ALPHA collaboration, was looking at antihydrogen atoms in which a positively charged antielectron, also known as a positron, orbits a negatively charged antiproton.
If you zap purified water with electric current, you can split apart a water molecule into a positively charged hydrogen ion and a negatively charged hydroxide ion (oxygen attached to hydrogen).
They immersed films made of cellulose acetate butyrate in solutions of phenyl azido and silica (which is positively charged) and phenyl azido and poly-allylamine hydrochloride (which is negatively charged).
Atoms of the material in question are accelerated to very high speeds, stripped of electrons (rendering them positively charged) and passed by a magnet that separates the nuclei of the atoms by weight.
One effect of the beam is to polarise the cloud of electrons surrounding each rubidium nucleus, meaning that part of the atom becomes a negatively charged pole, and part a positively charged pole.
The resin within the carbon layers is laced with lithium ions, so that each layer acts like an electrode, causing the positively charged lithium ions to collect in one layer when a voltage is applied, and a current to flow when the sandwich is placed in a circuit.
In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).
Grotzinger compares these minerals to batteries: positively and negatively charged compounds that together can spark the beginnings of life.
In this case, the voltage arises because the crystal deforms and a symmetry between positively and negatively charged atoms is disturbed.
