Submission Preparation Checklist

As part of the submission process, authors are required to check off their submission's compliance with all of the following items, and submissions may be returned to authors that do not adhere to these guidelines.
  • The manuscript will be declined if any of these are not provided (not just checked)!
  • The submission has not been previously published, nor is it before another journal for consideration (or an explanation has been provided in Comments to the Editor).

  • The submission file is in Microsoft Word document file format.

    The text is double-spaced; uses a 12-point font; employs italics, rather than underlining (except with URL addresses); and all illustrations, figures, and tables are imbedded in the text at the appropriate points, rather than at the end.

    The text adheres to the stylistic and bibliographic requirements outlined in the Author Guidelines, which is found in About the Journal.

  • ALL authors have read the manuscript and agree with its content.
  • I have added in the field Comments for the Editor the names, full institutional addresses and e-mails of five potential reviewers. (We check the publications of the reviewers and possible conflicts of interest.)
  • The metadata (properly witten name, e-mail, affiliation, reviewing fields, ORCID) for all the authors will be provided. If more authors appear in the submitted manuscript than in the metadata, the manuscript will be rejected.
  • For studies in humans or animals, statements confirming that the procedures were lawful and approved by relevant committees are included.

1. General Information

The Macedonian Journal of Chemistry and Chemical Engineering (MJCCE) is a peer-reviewed scientific journal published without article processing charges. The Editor and Editorial Board serve on a voluntary basis.

MJCCE does not publish extended abstracts from conferences or conferences special issues.

Authors are kindly requested:

  • Not to submit more than two manuscripts per calendar year
