Two dozen papers by IIT Dhanbad faculty retracted so far

With 24 and 26 retractions in one year, Dr. Rashmi Madhuri and Dr. Prashant Sharma, who are Assistant Professors at Indian Institute of Technology (Indian School of Mines), Dhanbad and coauthors in 40-odd papers, have the most retractions among researchers in India.

A few days back, nine more papers were retracted for the same reason as the earlier ones — duplication of images and passing them off as different materials/experiments. Another paper was retracted in October 2018. The first paper by the duo was retracted in February this year, followed by seven more retractions in March and April 2018. Four more papers were retracted the very next month. There are still over a dozen problematic papers listed on Pubpeer website, which allows users to discuss and review scientific papers that have been published.

The nine papers that were retracted a few days ago were published in RSC Advances (three papers), and one each appeared in Journal of Materials Chemistry A, Journal of Materials Chemistry B, Journal of Materials Chemistry C, Biomaterials Science and Chemical Engineering Journal. Another paper in ACS Applied Materials & Interfaces was retracted in October 2018 and the paper in Chemical Engineering Journal was retracted in March 2018.

The Royal Society of Chemistry, which publishes the journals that recently retracted the nine papers, told Retraction Watch: “The decision to retract is opposed by the authors, all of whom were contacted during the investigation process.

“Our investigations concluded that in nine papers it was apparent that the data and conclusions could no longer be relied upon due to inappropriate altering of images and duplication of data, which have been presented in a number of journals, including with other publishers.”

Investigation by IIT Dhanbad

In August, Prof. Rajiv Shekhar, Director of IIT Dhanbad said the investigation into possible scientific misconduct by a four-member fact-finding committee formed by the institute was completed. He had said that the scientific misconduct appears serious and may attract major penalty. According to the report would be sent to the Baord, which was supposed to meet in September end.

“The investigation is still on and will probably be completed by March-April [2019]. We are following due process,” said Prof. Shekhar.

Retracted papers get publicity

A November 2016 paper published in Chemical Engineering Journal and retracted in March 2017 was accepted as cover photo of the journal, according to Dr. Sharma.

Unfortunately, an August 2014 paper published in the journal Biosensors & Bioelectronics and retracted by the journal in January 2015 was highlighted by Nature India in September 2014. The Nature India report was reproduced by the Swiss Innovation Foundation (Embassy of Switzerland in India). The retraction note says: “The article uses several electron micrographs which have been used in other publications as well, denoting different samples… This problem with the data casts doubt on all the data, and accordingly also the conclusions based on that data, in this publication.”

Similarly, an October 2014 paper published in Analytica Chimica Acta and retracted in January 2015 was highlighted by Nature India in December 2014. The retraction note says: “The article reports different electron micrographs for different sample preparations, but some images are of different areas from the same sample…The article reports EDX spectra in Figure 5C and Figure 5D for samples that are reported as different…These problems with the data presented cast doubt on all the data, and accordingly also the conclusions based on that data, in this publication.”
