From their Oct 2005 paper ...

It is significant that 2.45 MeV D/D fusion neutrons were measured only when chilled, well-degassed, cavitated D-acetone was used. That is, no neutrons were measured when room temperature D-acetone, or as expected, normal acetone, was used.

So the obvious and cheap control was done after all.
