Materials Reports (MR) makes great effort to publish high quality, trusted content. To help us maintain these high standards, we provide guidelines of ethical publishing for authors, reviewers, and journal editors.

Materials Reports (MR) refers editors to the COPE Code of Conduct and Best Practice Guidelines for Journal Editors.

We ask all journal editors to make great effort to adhere to the following ethical guidelines.

●　Editors should give unbiased consideration to each manuscript submitted for consideration for publication, and should judge each on its merits, without regard to race, religion, nationality, sex, seniority, or institutional affiliation of the author(s).

●　Editors must keep the peer-review process confidential; information or correspondence about a manuscript should not be shared with anyone outside of the peer review process.

●　If an editor receives a claim that a submitted article is under consideration elsewhere or has already been published, then he or she has a duty to investigate the matter.

●　Editors may reject a submitted manuscript without peer review if they consider the manuscript to be inappropriate for the journal and outside its scope.

●　Editors should endeavor to process submitted manuscripts in an efficient and timely manner.

●　If an editor is presented with convincing evidence that the main substance or conclusions of an article published in the journal are erroneous, then, in consultation with Materials Reports (MR), the journal editor should facilitate publication of an appropriate corrigendum or erratum.
