A missed withdrawal request has led to doubled up publication and a later retraction for Brazilian physicists, through no fault of their own.
“Atmospheric Plasma Treatment of Carbon Fibers for Enhancement of Their Adhesion Properties” was presented at an Institute of Physics (IOP) conference in 2010. The proceedings weren’t published until May 2014.
In the meantime, the plasma scientists withdrew their paper from consideration and submitted it to IEEE Transactions on Plasma Science, where it was published in February 2013. Unfortunately, in the four year delay between the conference and the Institute of Physics publication, the withdrawal request got lost.
In September, we wrote about the retraction of a physics paper for “a pattern that was unphysical.”
The team, whose first author, R.K. Singhal refused to sign the notice, has had another paper retracted, this one in the Journal of Applied Physics. Here’s the notice for “Study of electronic structure and magnetization correlations in hydrogenated and vacuum annealed Ni doped ZnO:” Read the rest of this entry »
The paper was titled “Effect of hydrogenation vs. re-heating on intrinsic magnetization of Co doped In2O3.”
Denis de Jesus Lima Guerra, a co-author on 11 chemistry papers that were retracted in 2011 for suspicions of fraud, has lost his position at the Federal University of Mato Grosso (UFMT).
