Triolic Wave
From Star Trek : Freedom's Wiki
Triolic waves are the by-product of an energy source used by very few humanoid species due to their deleterious effects on living tissue. Triolic waves can also alter the composition of inorganic matter. Only the shapeshifter Devidians are known to use energy sources that produce triolic waves. (TNG: "Time's Arrow", "Time's Arrow, Part II")
