Rusi Taleyarkhan
From Wikipedia, the free encyclopedia
Rusi P. Taleyarkhan has been Arden Bement Jr. Professor of Nuclear Engineering at Purdue University since 2003. Prior to that, he was a Distinguished Scientist at the Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. He obtained his Bachelor of Technology degree in Mechanical Engineering from the Indian Institute of Technology, Madras in 1977 and MS and PhD (Nuclear Engineering and Science) degrees from Rensselaer Polytechnic Institute (RPI) in 1978 and 1982 respectively. He also holds an MBA (Business Administration) from RPI.[1]
[edit] Sonofusion work and controversy
In 2002, while a senior scientist at ORNL, Taleyarkhan published a paper on fusion achieved by bombarding a container of liquid solvent with strong ultrasonic vibrations, a process known as sonofusion or bubble fusion. In theory, the vibrations collapsed gas bubbles in the solvent, heating them to temperatures high enough to fuse hydrogen atoms and release energy. Following his move from Oak Ridge to Purdue in 2003, Taleyarkhan published additional papers about his research in this area.
Other scientists, however, were not able to replicate Taleyarkhan's work. In June 2006, Dr. Kenneth S. Suslick from the University of Illinois at Urbana-Champaign said in an e-mail to Peter E. Dunn, Purdue University's Associate Vice President for Research, that he believed Taleyarkhan's work might represent scientific misconduct. Suslick claims he received no response from Purdue.[2]
Taleyarkhan's results were reportedly repeated by Edward Forringer of LeTourneau University in Taleyarkhan's own labs at Purdue in November 2006,[3]. Purdue decided at that time not to further investigate initial narrowly defined charges of misconduct against Taleyarkhan made by other members of the Purdue Faculty.[2]
The Chronicle of Higher Education, however, has noted some problems with the verification. "During this time, Mr. Taleyarkhan says, two more scientists came into his laboratory and independently verified bubble fusion. Mr. Taleyarkhan contends that both were experts and did their work independently of him. But in interviews, both researchers contradict aspects of that account. One of those scientists, Edward R. Forringer, a professor of physics at LeTourneau University, in Texas, says he is certainly not an expert. Nonetheless, he says he is confident that his results do support the reality of bubble fusion." [4]
On May 10, 2007, Purdue announced that they would add at least one scientist without ties to the university to a new inquiry of Taleyarkhan and his work, at the insistence of a Congressional panel investigating the use of federal funds in attempts to reproduce Taleyarkhan's results. The panel cited concerns that Taleyarkhan's claims of independent verification were "highly doubtful", and criticized Purdue for using three of the same members of an earlier inquiry committee in their recently completed review. Taleyarkhan called the report a "one-sided, grossly exaggerated write-up" but agreed to cooperate.[5] On September 10, 2007, Purdue reported that its internal committee had determined that "several matters merit further investigation" and that they were re-opening the formal proceedings.[6]
