Brief description: element 109, meitnerium, is a synthetic element that is not present in the environment at all.
Isolation of an observable quantity of meitnerium has never been achieved, and may well never be.
This is because meitnerium decays very rapidly through the emission of α-particles.

  Meitnerium (Mt) - Chemical properties, Health and Environmental effects
None of meitnerium's chemistry has been researched, but it should resemble other elements of group 9, like iridium.
Meitnerium does not have any known application and little is known about it.
Meitnerium is not found free in the environment, since it is a synthetic element.

Meitnerium is a synthetic element and does not occur in nature.
The composer of this block chose to represent meitnerium with an artistic rendition of herself because of certain things she has in common with the element.
Not only does she share her initials (MT) with the element's chemical symbol (Mt), but as well, the atomic number, l09, taken as a date (1/09, Jan. 9) is the artist's birthday.

Meitnerium was first produced by Peter Armbruster, Gottfried Münzenber and their team working at the Gesellschaft für Schwerionenforschung in Darmstadt, Germany in 1982.
Meitnerium's most stable isotope, meitnerium-276, has a half-life of about 0.72 seconds.
Since only small amounts of meitnerium have ever been produced, it currently has no uses outside of basic scientific research.

 Pictures, stories, and facts about the element Meitnerium in the Periodic Table
Lise Meitner did not share the Nobel Prize for atomic fission with Otto Hahn, as many thought she should have, but she did get the last laugh--her own element, a far less fleeting honor than a mere Nobel.
This photograph of Lise Meitner appears in my Photographic Periodic Table Poster representing meitnerium, which is named after her.
This highly unstable element can't reasonably be photographed, and a picture of its namesake seemed like a reasonable alternative.

It may also contain some amount of nitrogen (N), which is inert, and doesn't effect the quality of the fuel; however, if the ratio of cerium to meitnerium is off at all, the air-filtering machines will jam up and be completely useless.
However, you do have a a cerinitrometer, which measures the ratio of cerium and nitrogen, and a nitmeitnerometer, which measures the ratio of nitrogen and meitnerium.
You discover the only elements in each container are cerium, meitnerium, and nitrogen, so one of containers may contain usable fuel.
