Sonofusion
Sonofusion eller boblefusion er en proces, hvor deuteriums atomkerner (tung brint) formodes at smelte sammen (fusionere) ved høje temperaturer under sonoluminiscente implosioner og danne nyt stof (helium eller tritium).
Rusi Taleyarkhan og hans gruppe har til en del eksperimenter anvendt deuteriumatomer bundet i tung acetone og benzen både i 2002 og 2005.
De seneste analyser af Taleyarkhans gruppes eksperimenter og replikering af gruppens eksperimenter har ikke kunnet påvise sonofusion. Man har ikke kunnet kæde de målte neutroner sammen med forekomsten af sonoluminescens.
Det betyder dog ikke nødvendigvis, at det er umuligt at lave sonofusion, men det er ikke endnu lavet overbevisende i praksis.

- 2004, CERN courier: Tabletop fusion claim is revisited Arkiveret 13. maj 2006 hos Wayback Machine Citat: "...claim that they had found evidence for neutron emission and tritium production in chilled, deuterated acetone when blasted with sound to produce sonoluminescence...This time the researchers report a "large and statistically significant" emission of neutrons...Control experiments using normal acetone did not result in significant tritium activity or in neutron or gamma-ray emissions. Now it remains to be seen how the physics community will respond to these results..."

To their surprise, they found temperatures could reach as high as 20,000 K..."Our results are in such a different set of experimental parameters that they can neither confirm or deny Taleyarkhan’s claims to fusion," Suslick told PhysicsWeb. "A plasma is a prerequisite but certainly not a sufficient condition for fusion."..."
