Kudos to @roysocchem.bsky.social for retracting 2 papers. This artist/author has 24 papers flagged on @pubpeer.com for all kinds of image concerns. The RSC is the first one to retract his artwork published in their journals. #ImageForensics pubpeer.com/publications... pubpeer.com/publications...
Screenshot from DOI: 10.1039/d1ra08523a, published in RSC Advances, depicting five XRD patterns labeled a through e. The patterns look like horizontal squiggly stripes with some vertical peaks. I have added rectangular boxes in different colors depicting some squiggly parts that look remarkably similar. The one I marked with a blue box is even repeated within the same pattern. Image taken from DOI: 10.1039/d3na00805c, showing NMR spectra published in Figures S3 (top, depicting compound '4m') and S6 (bottom, showing compound '6g'). These look like vertical stripes of different lengths plotted along an X axis from 200 to 0 ppm. Some text on the right. I have added boxes in different colors showing unexpected similarities between the two figures.

Neptune by JWST. 🔭 🧪
Webb’s Near-Infrared Camera (NIRCam) image of Neptune, taken on 12 July 2022, brings the planet’s rings into full focus for the first time in more than three decades. The most prominent features of Neptune’s atmosphere in this image are a series of bright patches in the planet’s southern hemisphere that represent high-altitude methane-ice clouds. More subtly, a thin line of brightness circling the planet’s equator could be a visual signature of global atmospheric circulation that powers Neptune’s winds and storms. Additionally, for the first time, Webb has teased out a continuous band of high-latitude clouds surrounding a previously-known vortex at Neptune’s southern pole.
