What’s more, the authors omitted key findings that would enable others to reproduce their experiments.
According to the notice, the authors used a value to calculate a feature of electrons—called mobility—that “was approximately 100 times too small,” which led to results that were “100 times too large.” The notice also details several gaps in the presentation of experimental results, which preclude others from duplicating the experiments.
Here’s the retraction notice for “Bulk- and layer-heterojunction phototransistors based on poly[2-methoxy-5-(2′-ethylhexyloxy-p-phenylenevinylene)] and PbS quantum dot hybrids:” Read the rest of this entry »
A physics journal has retracted a 2016 study after learning that the author published it without the knowledge or permission of the funder, which had a confidentiality agreement in place for the work.
According to the retraction notice in Applied Physics Letters, the paper also lifted content from other researchers without due credit. Given the “legal issue” associated with the breach of confidentiality, the journal has decided to remove the paper entirely.
Graphene has been hot for several years. Here’s what the Royal Swedish Academy of Sciences had to say about it in 2010 when awarding two researchers the Nobel Prize in Physics for their work:
Graphene is a form of carbon. As a material it is completely new – not only the thinnest ever but also the strongest. As a conductor of electricity it performs as well as copper. As a conductor of heat it outperforms all other known materials. It is almost completely transparent, yet so dense that not even helium, the smallest gas atom, can pass through it. Carbon, the basis of all known life on earth, has surprised us once again.
But one researcher may have allowed his enthusiasm for graphene to get ahead of him. He and his unwitting co-authors have now lost two papers thanks to that enthusiasm. Read the rest of this entry »
Obfuscation watch: Self-plagiarism (we think) leads to retraction of nanorod paper in Applied Physics Letters
C. P. Snow famously bemoaned the gulf between science and the humanities. The following retraction might be the sort of thing that would have given the physicist-cum-author fits for its estrangement from the English language.
Writing in the latest issue of Applied Physics Letters, a team from
China Singapore and MIT appear to be confessing a case of self-plagiarism in their 2005 paper, “Growth of single crystal ZnO nanorods on GaN using an aqueous solution method: (we added a link to the earlier paper)” Read the rest of this entry »
