Here’s one notice, for “Laser-induced gold/chitosan nanocomposites with tailored wettability applied to multi-irradiated microfluidic channels:”
We, the named authors, hereby wholly retract this RSC Advances article. This article was submitted for publication without the knowledge and approval of all the authors listed.
Signed: Fabrizio Spano, Alessandro Massaro, Roberto Cingolani and Athanassia Athanassiou, Italy, October 2012.
Retraction endorsed by Sarah Ruthven, Managing Editor, RSC Advances. Retraction published 2nd October 2012.
The surprised author would appear to be Laura Blasi of Italy’s National Nanotechnology Laboratory, who is on the original author list but did not sign the retraction.
The other retraction is of “Aligned nanoporous PtNi nanorod-like structures for electrocatalysis and biosensing:”
We, the named authors, hereby wholly retract this RSC Advances article, due to unreliable experimental results which cannot be repeated.
Signed: Huajun Qiu, Liang Li, Qiaolin Lang, Feixue Zou and Xirong Huang, China, September 2012.
Retraction endorsed by Sarah Ruthven, Managing Editor. Retraction published 26 September 2012.
We’ve contacted the corresponding authors of the papers, as well as Ruthven, for more information about the reasons for the retractions, and will update with anything we learn.
Update, 8:50 p.m. Eastern, 10/15/12: Huajun Qiu, corresponding author of the second paper, tells Retraction Watch:
The unreliable result came to our attention because the ternary alloy we used contains many different alloy phases. After dealloying, by detailed analysis, we found the dealloyed sample had nonuniform morphology. These porous metals may be very useful for catalysis; however, for sensing application, uniform structure is necessary.
Right now, we are focusing on the fabrication of uniform structures by dealloying single-phase alloy.
Please see an update on this post, with a publisher correction to the retraction notice.
