A gang of Indian nanotechnology scientists, allegedly from Annamalai University in India, placed in 2014-2015 several papers in different journals, all of them about nanoparticle synthesis using extracts from various local plants. Most papers went into the journal Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, published by Elsevier. The publications were harshly criticised on PubPeer for their poor science, but also for suspected data manipulations (electron microscopy images, photographs of bacteria dishes and X-ray diffraction measurements were reused across different unrelated papers, see PubPeer examples below).
Five nanotechnology papers at Elsevier are now about to be retracted, at least four of them from Spectrochimica Acta Part A. The concerns about research quality and data integrity may have been however less decisive here. The faculties of the Annamalai University carry no mention of any of these authors as their members, all of the provided corresponding email addresses are from Gmail. A publishing scam, possibly including fraudulent peer review, is the likely reason why these papers are being retracted now. Continue reading “The smelly compost heap of plant-based nanoparticles”
