Apart from the apparent manipulation of the x-ray refinement, many aspects of the original article should have aroused suspicion. Any long paper with 66 citations should be returned for revision.
The paper claims to optimise the heating of magnetic nanoparticles dispersed in a biological medium subjected to a fluctuating magnetic field, by doping magnetite with Tb. Such magnetic colloids are used to apply moderate local heat at cancer sites in a treatment called "magnetic hyperthermia". Heat therapy has a long history going back to the treatment of syphilis, but how effective it is, is not clear. And it seems unlikely that doping a magnetite colloid is going to greatly increase its efficiency to generate heat in a magnetic field, but perhaps it depends on how dispersed the particles are, as the authors claim. They should perhaps have concentrated on demonstrating the claimed improved performance. Jumping to HREM and Rietveld Refinement of the structure of the doped magnetite nanoparticles is bizarre. Just because you have all these techniques available doesn't mean that they can contribute, even if the data is not manipulated. ________________________________ Dr Alan Hewat, NeutronOptics Grenoble, FRANCE (from phone) alan.he...@neutronoptics.com +33.476984168 VAT:FR79499450856 http://NeutronOptics.com/hewat _______________________________ On Wed, 27 Mar 2024, 07:26 Le Bail Armel, <le-bail.ar...@orange.fr> wrote: > Retracted : > https://link.springer.com/article/10.1038/s41598-024-57685-9 > > > *envoyé :* 15 janvier 2024 à 20:05 > *de :* Le Bail Armel <le-bail.ar...@orange.fr> > *à :* Le Bail Armel <le-bail.ar...@orange.fr> > *objet :* Re: Misconduct > > Frightening. > > Searching for “Rietveld refinement” in Google Scholar for 2024 gives > already >1300 entries.
