Three more instances of plagiarism committed by C.N.R. Rao, eminent scientist and Scientific Adviser to the Prime Minister, and S. B. Krupanidhi, senior professor at Indian Institute of Science (IISc) in Bangalore, have come to light. Professor Krupanidhi's student Basant Chitara at the IISc is the first author of two papers.
Nearly one-third of the introduction section of a paper published by these authors and another student in the December 2011 issue of the Journal of Luminescence has been plagiarised. The 20 unattributed lines have been lifted almost verbatim from two papers published in the June 2009 issue of Nanotechnology and January 2006 issue of Advanced Materials .
G. Itskos from the Department of Physics, University of Cyprus, is the first author of the paper in the Nanotechnology , and George Heliotis from the Imperial College, London, is the first author of the paper in the Advanced Materials .
Quite surprisingly, these two authors are unaware of the research misconduct by the Indian authors.
Similarly, a paper published in 2009 in Nanotechnology , with Chitara as the first author and the two senior researchers and another student as co-authors, has nearly six lines in the introduction taken almost verbatim without attribution from a 1995 paper by Z.C. Huang et al., in the Applied Physics Letters journal. It also contains a few lines taken from a 2005 book by Peter Y. Yu and Manuel Cardona (“ Fundamentals of semiconductors: Physics and materials properties ”)
Another paper published in 2010 in the Applied Physics Express suffers from the same kind of transgression. The first author here is S. Venkataprasad Bhat from the Jawaharlal Nehru Centre for Advanced Scientific Research in Bangalore and the two senior scientists are the co-authors. Seven lines in the very beginning of the introduction have been plagiarised from a 2008 paper by P. Matheu, et al, published in the Applied Physics Letters .
These disclosures in a blog by an anonymous person come close on the heels of a PTI report about two weeks ago of plagiarism committed by these researchers.
The PTI report was about the plagiarised lines in a July 2011 paper published in Advanced Materials . The 12 lines were lifted almost verbatim from the April 22, 2010 paper of Surajit Ghosh et al., in the Applied Physics Letters .
“We go through checks several times. However, the exact lines [that] appear in the introduction may not be detected by senior authors. Senior authors mainly focus on experimental results, analysis and interpretation of results,” Professor Krupanidhi replied through email to questions raised by The Hindu .
