TOS: "The Devil in the Dark" - Horta happens to be a silicon-based lifeform.
It makes sense that a silicon-based lifeform can digest many sorts of stone (=silicon). But on the other hand, we donÃƒâ€šÃ‚Â´t eat coal either...

Theta band emissions

Artificially generated by crew and by aliens. Sort of subspace radiation, used for communication, the starfleet theta band communication frequencies A, B and C can be masked as ordinary subspace background radiation.
Supplement by Bernd: This is obviously supposed to be something different than theta radiation.

TNG: "Chain of Command, part I" - The Cardassians were suspected to use theta band carrier waves to transport metagenic weapons, theta band emissions from Celtris III led to the supposition that a weapons lab could be located there.
"Star Trek Generations" - Geordi detects theta band emissions that may emerge from trilithium. Supplement by Bernd

Submitted by Alex Hoffmann

Theta radiation

Yes it's toxic and it's radiation, but don't mind, we have inoculation for that...

A real-world isotope also known as radon 220.

DS9: "The Way of the Warrior" - Martok suspected that thoron emissions created false sensor readings of new weapons on Deep Space Nine. Likely a reference to the bluff played in "Emissary". Submitted by Michael Warren

Toh-maire gas

Naturally occuring. Indigenous name of the Rakhari for a highly instable and therefore easily combustible gas inside the Chamra vortex.
Concerning its instable properties it's similar to Sirillium and Metreon gas, so it's a typical "explosive-gaseous-anomaly-saves-the-day"-gas.

DS9: "Vortex" - Ah-kel's ship is destroyed by an explosion of a bubble of toh-maire gas.

"Star Trek: The Voyage Home" - Scotty showed a scientist how to make it, in exchange for a supply of plexiglas to build a whale tank.
Since aluminium can't be transparent and Scotty devised something remotely similar to a chemical formula, I assume it's a compound.

Curiously, Riker doesn't know trilithium here, although it is a by-product of the Enterprise's warp core...

Naturally occuring. A mineral substance.
It is unlikely that "323" denotes the number of nuclei of a particular trillium isotope, because in this case the number looks like it should belong to an already known element.

TOS: "Errand of Mercy" - Spock pretended to be a trillium dealer.
TNG: "The Price" - Used as a bargaining tool in the Chrysalian bid for the Bazaran Wormhole.

Tritium

Naturally occuring. Mildly radioactive isotope, used in Klingon warp drives.
A radioactive isotope of hydrogen with atoms of three times the mass of ordinary light hydrogen atoms. Tritium has a half-life of about 12.3 years. Tritium likely fullfills the same function in warp cores as deuterium (both being isotopes of hydrogen), so there has to be also anti-tritium on Klingon vessels.

DS9: "Q-Less" - Used by Dax and O'Brien to trace the origins of the gravimetric disturbances.

Uridium

Naturally occuring. Unstable mineral substance. The material is highly explosive when exposed to strong electric charges. It has to be cooled when it's processed.

DS9: "Civil Defense" - Terok Nor processed raw uridium ore.
DS9: "Indiscretion" - Cardassians use a uridium alloy in their sensor arrays.

VOY: "Parallax" - Evidence of the Voyager's path in the singularity.

Warp plasma

Artificially generated by crew. Residual plasma created by matter/antimatter reaction. Discharging a phaser or disruptor near warp plasma particles will cause them to ignite. Transporter beams can also destabilize warp plasma. See also Plasma.

VOY: "Fair Trade" - Tosin demanded that Wixiban and Neelix provide him with three grams of warp plasma to improve their engine efficiency.

Warp shell

Artificially generated by crew. A field generated by the Enterprise's engines to induce warp travel.

TNG: "All Good Things" - Picard used static warp shells to seal the temporal rifts in the three time instances.

Wormhole

Naturally occuring. A tunnel between two remote points in normal time and space. Most wormholes are extremely unstable and their end points fluctulate widely across time and space. An improperly balanced warp drive system can create an artifical wormhole that can pose a serious danger to the ship and its crew.
Wormholes are a real-world scientific idea. They may be considered as two gravity wells by black holes that are connected to each other.

"Star Trek: The Motion Picture" - The Enterprise artificially generates a wormhole due to a warp engine imbalance.
TNG: "The Price" - The Barzan Wormhole appears to be stable, but its far end is moving through the Delta Quadrant.
DS9: all episodes - The only known stable wormhole, leading to the Gamma Quadrant, is located in the Denorios Belt of ther Bajoran star system, lending Deep Space Nine its strategic importance to the Federation.
VOY: "False Profits" - An attempt to stabilize the far end of the Barzan Wormhole almost succeeds.
VOY: "Eye of the Needle" - A micro-wormhole with a diamater of only few centimeters is found. It is leading through space into the Alpha Quadrant and into the past.

X

X-rays

Artificially generated by crew. Form of radiation which is not technically used any longer in medical imaging.
Electromagnetic waves with wavelenghts from about 10^-8m to about 10^-11m.

VOY: "Tuvix" - X-rays were used in early medical imaging scanners in the late 21st century.

Y

Yominium sulfide

Origin unknown. An element.
Its existence is implied by "yominium sulfide".

"Star Trek: The Voyage Home" - Spock recalls the chemical formula for yominium sulfide.

Yominium sulfide

Origin unknown. A chemical compound.
The name is derived from "Nimoy" spelled backwards.

"Star Trek: The Voyage Home" - Spock recalls the chemical formula for yominium sulfide K₄Ym₃(SO₇3Es₂) during a memory test during his re-education of Vulcan.
The formula is inconsistent with that of a sulfide.

Yridium bicantizine

Artificially generated by aliens. Very rare but tremendously important component of Ketracel white, it is made of a trinucleic fungus.
Was this actually supposed to be a compound of the real-world element iridium?

DS9: "Statistic Probabilities" - The Dominion tried to get hold of a planet in the Kabrel system were trinucleic fungi occur.

Z

Z-particle

Artificially generated by aliens. A particle. Can mess up sensor and/or visual records.
Also a real type of particle. In real life: today's understanding puts particles into two basic categories, matter and exchange particles. Exchange particles are thrown kind of like frisbees between matter particles as the generators of the forces. Photons mediate the electromagnetic force, gluons mediate the strong force, the graviton is proposed (not observed) to mediate the gravitational force. The weak force is mediated by the W+, W-, and Z₀ particles.

TNG: "Devil's Due" - Scientist on Ventax II station detected Z-particles coming from Ardra's ship.
TNG: "Identity Crisis" - LaForge initiated a scan for Z-particle emissions on the video recording of the Tarchannen III mission.

Zenite

Naturally occuring. A raw mineral from which a potent compound is derived by the Federation for use in stopping botanical plagues.

TOS: "Cloud Minders" - Zenite in its naturally found state causes temporary mental impairment when its dust is breathed. Such an effect had profound social implications in separating the Troglyte miners from the Stratos city dwellers, an issue which the crew of the Enterprise had to deal with.
