I've just finished reading the novel Star Trek: The Next Generation 'Cold Equations: The Persistence of Memory' (great book by the way). On page 358 of my edition (the start of Chapter 31), Picard says the following:
Picard resisted the urge to curse the docelerite that kept his ship mired at impulse, and which made it impractical to fire photon torpedoes and shift to evasive maneuvers.
I know that this book can't be considered canon, nevertheless I went to the Memory Beta page for the book and it does say it refers to docelerite, which is apparently an 'element', but there is no page explaining what it is. This docelerite sounds like its pretty important and I was just wondering if there is any reference elsewhere in Star Trek materials that explains what this is.
(For those of you who haven't read the book, this is set on the Enterprise-E)
