I'm trying to submit a paper, but two different manuscripts are being prepared. One is by me and one is by a collaborator who is using my samples. I know it's unethical to reuse the same data in two different publications, so I know I shouldn't reuse the same images/data. However, if I use a different image of the same sample, would that still constitute a breach of ethics?
The two papers have a different focus. One is about synthesis and structural, morphological, and electrical characterization for samples calcined at different temperatures. The other compares one sample from the previous with two others and uses EDS and XPS to prove that the particles have a core-shell structure.
I want to make sure I don't accidentally overstep any ethical boundaries with regard to publishing.
