Policy declarations must be complete at submission and remain consistent with the manuscript and supporting files.
Peer review
Peer review: Single-blind by default; double-blind review is available on request.
Manuscripts that proceed to external peer review are normally evaluated by at least two independent subject-matter experts.
For double-blind review, remove author names, affiliations, acknowledgments, funding details, institution names, and other identifying information from the reviewer manuscript. Provide identifying information separately in the title-page file or submission form.
Clinical-trial registration: when applicable
This requirement applies only to an in-scope chemistry study with an interventional human component that constitutes a clinical trial. It does not broaden JNDC's scope to purely clinical research or apply automatically to laboratory studies using human samples.
Interventional clinical trials must be registered in an accepted public trial registry at or before the first participant provides consent for enrollment. The registry name, registration number, and registration date must be reported in the manuscript.
Reporting guidance
Use the reporting guideline appropriate to the work, including CONSORT, STROBE, PRISMA, CARE, STARD or ARRIVE where applicable. Report statistical methods, assumptions, uncertainty, replication and exclusions clearly.
AI-assisted work
AI tools cannot meet authorship criteria. Authors remain accountable for all submitted content and should disclose material use of AI-assisted tools in preparing text, code, images or analyses in accordance with the journal's current policy.
