A - F | G - P | Q - Z
Naturally occurring. Causes duonetic fields, resulting in equipment failures.
- DS9: Paradise - Acetin deposits in the swamp beds near Alixus' community prevented equipment from operating.
Naturally occurring. In real life, a neurotransmitter produced by the brain.
- DS9: Melora - Bashir used a medication designed to increase acetylcholine absorption to increase Melora's tensile muscular strength, thus enabling her to walk.
- Voyager: The Chute - Increased amounts of acetylcholine in Kim's nervous system caused him (and others in the prison camp) to exhibit erratic behavior.
Artificially generated by crew. Gaseous chemical. Toxic to humans, essential to advanced humans. In real life, acid dichloride is impossible as chlorine and hydrogen combine in a 1:1 ratio, and chemicals tend to separate into the lowest possible number of atoms. Acid "di"chloride would be H2Cl2, and this would break down into HCl: hydrochloric acid or (when a gas) hydrogen chloride.
- Voyager: Threshold - The Doctor determines that the evolved Tom Paris requires acid dichloride gas to breathe.
Naturally occurring. Radioactive compounds generally found in uranium ore. Actinides are known to interfere with Federation sensors.
- TNG: The Mind's Eye - The crew of the Enterprise encountered these in the Ilkalian asteroid belt. The actinides made it difficult to locate the Kriosian rebels.
Naturally occurring. In real life, protects embryos from disease while in the womb.
- TNG: Genesis - Cured the outbreak of Barclay's Protomorphosis Syndrome.
Artificially generated by crew. A general anesthetic. Fatal if present in the air.
- DS9: The Siege - Terrorists flooded the station's conduits with concentrated anesthizine gas to try to kill the crew.
- TNG: Rascals - Ro suggests using anesthizine gas to knock out the Ferengi. Unfortunately, Picard points out that it's not possible since computer control has been locked out.
- TNG: The Hunted - Picard orders that the cargo decks be flooded with anesthizine gas in order to try to knock out the fugitive Roga Danar.
Artificially generated by crew. Cancels out chroniton particles.
- Voyager: Before and After - When Kes was irradiated with chroniton particles from the Krenim and later subjected to a biotemporal field, she began to shift backwards in time. This was cured by the use of an antichroniton field.
Artificially generated by aliens. Apparently can act as "antigravity." In real life, a graviton (which is still a theoretical particle whose existence hasn't been proven) is its own antiparticle. That is, an antigraviton would actually be a normal graviton.
- TNG: Attached - Was used by aliens to deflect a transporter beam to a new set of co-ordinates.
Artificially generated by aliens. Prevents communications.
- DS9: Emissary - Gul Jassad's fleet flooded subspace with antilepton interference.
Artificially generated by crew; naturally occurring in real life. Matter whose electrical charge properties are the opposite of "normal matter." It is not well understood why the universe is made overwhelmingly of matter yet most reactions which produce particles produce matter and anti-matter equally. The imbalance could have started as a minor percentage in the early moments of the big bang, with resulting annihilation keeping the excess only (the rest is the photon background).
- Used to power the warp engines on Federation (and other) vessels. It's mentioned in countless episodes in all the series.
Naturally occurring. In real life, a byproduct of beta decay.
- Voyager: Prime Factors - After B'Elanna installed the Sikarian space "folding" mechanism, the device generated antineutrino particles as a part of the process of its normal operation. These particles proved harmful to the Federation warp core and almost caused a core breach. Fortunately B'Elanna thought quickly and phasered the device out of existence before any serious harm was done.
A real particle; the antimatter version of a neutron.
- Movie: IV: Voyage Home - Computer prompts Spock to "adjust the sine wave in the gravity envelope so that antineutrons may pass but antigravitons cannot"

Naturally occurring. Analogous to "antimatter" but for time, not matter.
- TNG: All Good Things - Produced as a result of the time rupture, which was caused by three dechyon beams from different timeframes intersecting.
Artificially generated by crew. Caused by the interaction between phased and normal matter. In real life, an anyon isn't a real particle, it's a theoretical construct formed by confining a normal fermion (and possibly boson) to a two-dimensional region. The exchange arguments which lead to the parity operator eigenvalues being +-1 no longer apply, and these theoretical constructs can have arbitrary quantum phase changes under exchange.
- TNG: The Next Phase - Data hypothesized that the bursts of anyons were caused by phased matter. When Geordie and Ro set off a disruptor on overload, a huge burst of anyons were detected, leading Data to sweep the area with amnions and save Geordie and Ro.

- TOS: The Deadly Years - Kirk uses the same ploy to escape Romulans!!
Artificially generated by crew. A drug.
- TOS: City on the Edge of Forever - McCoy accidentally injects himself with a huge dose, goes insane, and beams down to a planet where he, Kirk and Spock enter a time travel portal.
Naturally occurring. Rich deposits of this compound are found on the Kazon-Ogla Homeworld, which they use for barter with the other Kazon sects.
Artificially generated by crew. Used in thruster packs.
- TNG: Disaster - Geordie and Beverly had to get rid of the containers of corodum, because the plasma fire was overheating them. They opened the cargo bay doors, and released the containers into space.
Naturally occurring. A string of particles with gravitational forces that are the strength of a black hole.
- TNG: The Loss - A flurry of energy based entities surrounding the Enterprise D were headed for it, dragging the ship toward certain destruction. These creatures disabled counselor Troi's empathic powers for a time. The cosmic string was home to them.

Artificially generated by crew. In real life, dechyons are the class of particles that travel below the speed of light (i.e., the opposite of tachyons.)
- Voyager: Parallax - Used to open a fissure in an event horizon (no, that concept doesn't make any sense to me either.)
- TNG: Cause and Effect - The crew detected these particles as remnants of each "causality loop" and Data used them to send a message into the next loop, which allowed them to break this most vicious cycle.
Naturally occurring. Type of radiation produced by older engines; exists in real life. Delta-rays refer to moderate energy electrons which have been kicked off a nucleus by the passage of a nearby high energy charged particle.
