ANY attempt to achieve fusion in a bubble of acetone, proposed earlier this year in a controversial paper in Science, would be doomed to failure according to an analysis in Nature this week (vol 418, p 394).
When a tiny bubble collapses quickly it generates a huge amount of heat. Some researchers believe that when a perfectly round bubble collapses it could reach the millions of degrees required for nuclear fusion (Â鶹´«Ã½, 9 March, p 4).
But Yuri Didenko and Kenneth Suslick from the University of Illinois at Urbana-Champaign show that chemical reactions happening inside the bubble…
