Bubble fusion

Bubble fusion is the non-technical name for a nuclear fusion reaction hypothesized to occur inside extraordinarily large collapsing gas bubbles created in a liquid during acoustic cavitation. The more technical name is sonofusion; the term was coined in 2002 with the release of a report by Rusi Taleyarkhan and collaborators that claimed to have observed evidence of sonofusion. The claim was surrounded by controversy, including allegations ranging from experimental error to academic fraud. Subsequent publications claiming independent verification of sonofusion were highly controversial. An investigation by Purdue University found that Taleyarkhan had engaged in falsification of independent verification, had included a student as an author on a paper when he had not participated in the research, he was subsequently stripped of his professorship. One of his funders, the Office of Naval Research reviewed the report by Purdue and barred him from federal funding for 28 months. US patent 4,333,796, filed by Hugh Flynn in 1978, appears to be the earliest documented reference to a sonofusion-type reaction.

In the March 8, 2002 issue of the peer-reviewed journal Science, Rusi P. Taleyarkhan and colleagues at the Oak Ridge National Laboratory reported that acoustic cavitation experiments conducted with deuterated acetone showed measurements of tritium and neutron output consistent with the occurrence of fusion; the neutron emission was reported to be coincident with the sonoluminescence pulse, a key indicator that its source was fusion caused by the heat and pressure inside the collapsing bubbles. The results were so startling, that the Oak Ridge National Laboratory asked two independent researchers, D. Shapira and M. J. Saltmarsh, to repeat the experiment using more sophisticated neutron detection equipment, they reported. A rebuttal by Taleyarkhan and the other authors of the original report argued that the Shapira and Saltmarsh report failed to account for significant differences in experimental setup, including over an inch of shielding between the neutron detector and the sonoluminescing acetone.

According to Taleyarkhan et al. when properly considering those differences, the results were consistent with fusion. As early as 2002, while experimental work was still in progress, Aaron Galonsky of Michigan State University, in a letter to the journal Science expressed doubts about the claim made by the Taleyarkhan team. In Galonsky's opinion, the observed neutrons were too high in energy to be from a deuterium-deuterium fusion reaction. In their response, the Taleyarkhan team provided detailed counter-arguments and concluded that the energy was "reasonably close" to that, expected from a fusion reaction. In February 2005 the documentary series Horizon commissioned two leading sonoluminescence researchers, Seth Putterman and Kenneth S. Suslick, to reproduce Taleyarkhan's work. Using similar acoustic parameters, deuterated acetone, similar bubble nucleation, a much more sophisticated neutron detection device, the researchers could find no evidence of a fusion reaction. In 2004, new reports of bubble fusion were published by the Taleyarkhan group, claiming that the results of previous experiments had been replicated under more stringent experimental conditions.

These results differed from the original results in that fusion was claimed to occur over longer times than reported. The original report only claimed neutron emission from the initial bubble collapse following bubble nucleation, whereas this report claimed neutron emission many acoustic cycles later. In July 2005, two of Taleyarkhan's students at Purdue University published evidence confirming the previous result, they used the same acoustic chamber, the same deuterated acetone fluid and a similar bubble nucleation system. In this report, no neutron-sonoluminescence coincidence was attempted. An article in Nature raised issues about the validity of the research and complaints from his Purdue colleagues. Charges of misconduct were raised, Purdue University opened an investigation, it concluded in 2008 that Taleyarkhan's name should have appeared in the author list because of his deep involvement in many steps of the research, that he added one author that had not participated in the paper just to overcome the criticism of one reviewer, that this was part of an attempt of "an effort to falsify the scientific record by assertion of independent confirmation".

The investigation did not address the validity of the experimental results. In January 2006, a paper published in the journal Physical Review Letters by Taleyarkhan in collaboration with researchers from Rensselaer Polytechnic Institute reported statistically significant evidence of fusion. In November 2006, in the midst of accusations concerning Taleyarkhan's research standards, two different scientists visited the meta-stable fluids research lab at Purdue University to measure neutrons, using Taleyarkhan's equipment. Dr. Edward R. Forringer and undergraduates David Robbins and Jonathan Martin of LeTourneau University presented two papers at the American Nuclear Society Winter Meeting that reported replication of neutron emission, their experimental setup was similar to previous experiments in that it used a mixture of deuterated acetone, deuterated benzene, tetrachloroethylene and uranyl nitrate. Notably, however, it operated without an external neutron source and used two types of neutron detectors.

They claimed a liquid scintillation detector measured neutron levels at 8 standard deviations above the background level, while plastic detectors measured levels at 3.8 standard deviations above the background. When the same experiment was performed with non-deuterated

Ian Browne (cyclist)

Ian Browne known as "Joey" Browne is a former Australian track cyclist who along with Tony Marchant won the 2000 m tandem event at the 1956 Summer Olympics in Melbourne. Unusually tall and built for a cyclist, Browne had little formal training and won his first Australian title in 1953 in the 10 mile event. Browne did not team up with Marchant until early in 1956 and they promptly won the tandem event at the national championships to earn national selection; the pair were eliminated after losing their first two races but were given a reprieve when the Soviet Union pair were hospitalised in a crash and forced to withdraw. Thereafter Marchant and Browne were progressed to an unlikely Olympic gold. Browne's combination with Marchant was broken after the Olympics. In 1958, Browne won the 10 mile event at the national titles and went on to win the event at the 1958 British Empire and Commonwealth Games. Browne went on to compete in the 1960 and 1964 Olympics in the tandem event, both times with new partners, but both times he was eliminated in the repechage round.

In 1964, he became the oldest track cyclist to represent Australia at the Olympics at the age of 33. He won the last of his national titles at the age of 37 in 1968 in the tandem event but was overlooked for Olympic selection by Australian officials, he retired and was involved in cycling administration. Browne was born in Melbourne to the second of three brothers, his father was a printer and Browne took his elementary education at Chatham Public School, before moving on to Box Hill High School and took his university education at Royal Melbourne Institute of Technology. While he was at university, he worked in Sunshine as a laboratory assistant at Spaldings. At the age of 20, he graduated from RMIT and took a job at the State Electricity Commission, where he worked for over 35 years continuously since always riding his bicycle to work, a daily journey of around 15 km. Browne learned to ride a bicycle at the age of four, but did not enter his first formal cycling competition until the age of 16, when he joined the Hawthorne Amateur Cycling Club.

Browne made a habit of riding to training with his ordinary bike with heavy wheels to the club, carrying the lighter racing tyres on his back and changing his tyres upon his arrival. He earned extra money to fund a bicycle upgrade by working as a newspaper boy. There was little formal coaching at the club, the cyclists learned by individual application and by watching and copying others. Browne and his club-mates trained on Sundays. Browne had his first success at a major competition when he won the 10 mile at his first Australian Championships in 1953, he did not team up with Tony Marchant until the start of 1956, just ten months before the start of the Melbourne Olympics. Marchant had risen to prominence by winning the 500 m time trial at the 1955 Australian Championships for juniors, prompting Browne to select him as his partner based on his raw speed. For a final test run before formally committing to racing together, the pair had a few tandem sprints around the track, with Browne sitting in the front seat.

They were a contrasting pair. The pair went on to win the 2000 metre tandem event at the Australian Championships in 1956, but going into the Melbourne Olympics, themselves included, regarded them as realistic medal chances. However, their mentor, former champion Billy Guyatt convinced them that they had the potential to make progress at international level, their training schedule consisted of individual training two or three times a week and two days a week of coordinated tandem training during the Olympic year. Marchant's main tactical responsibility was to look to the outside for impending attacks while Browne patrolled the inside. Marchant devised a signal system, such as a head bump on Browne's hip, or a verbal shout when the opposition made a move. Ten nations were entered in the tandem competition, in the first round, they were drawn with Germany and South Africa, who fielded their silver medallist pairing of Tom Shardelow and Ray Robinson from the 1952 Summer Olympics in Helsinki; the Australians made their move too early and led at the ringing of the bell at the start of the last lap, but they were overhauled well before the line as they faded in the final straight.

Browne and Marchant were given another chance in the repechage round in the same day. The Australians lead for three quarters of the distance, but were overhauled by their Czechoslovakian opponent in the final metres and were defeated in a photo finish; this would have meant that the Australians would have been eliminated, however the final repechage between the Soviet Union and the Germans resulted in a tangle, resulting in a heavy pile-up. Neither team finished the race; the cycling officials decided that the bruised Germans would be forced to compete in a repechage sequel against the losers in the previous repechages to qualify. This allowed the Australians a reprieve; the Australians set their fastest time to date with 11.0 seconds. Having been beaten twice after leading out, the Australians sat back before sweeping past the injured Germans and the Americans in the final lap. Australia were again drawn against South Africa in their quarter-final, who had defeated them in the heats; this time they equalled the fastest team in the competition over the final 200 m, clocking 10.8 s to progress to the final, where they faced the Italy.
