elementary particle

n.
Any subatomic particle, such as one of the fundamental fermions or gauge bosons, that may be a component of other particles but is not made of components itself. Also called fundamental particle.

elementary particle

n
(General Physics) any of several entities, such as electrons, neutrons, or protons, that are less complex than atoms and are regarded as the constituents of all matter. Also called: fundamental particle

el′emen′tary par′ticle


n.
any of the fundamental units of matter or radiation, including such particles or quanta as the leptons, the hadrons, the photon, and the graviton.

el·e·men·ta·ry particle

(ĕl′ə-mĕn′tə-rē)
Any of the smallest known units of matter, such as quarks and neutrinos. Elementary particles are not made up of smaller units.

In practical terms, that means supersymmetry's math implies that for every known subatomic matter particle the universe should provide a corresponding forcelike particle, and for every force particle there should exist a matterlike partner.
The matter and antimatter characteristics in the Majorana particle did not vanish, but are maintained in a different way, probably through rapid inter-conversion of the one to the other through the exchange of some force particles.
Rather than using pressure to force particles through, the system uses an electric current to move small peptides--which in normal pH can develop positive and negative charges -through a stacked series of filtration membranes.
