Thamar University Journal of Natural & Applied Sciences

The TUJNAS Editorial Board invites submissions for Volume 11, Issue 2 (to be published December 2026). We encourage authors worldwide to submit their latest research and reviews in any area of natural or applied science. Papers should report new and original results in fields such as physics, chemistry, biology, engineering, medicine, environmental science, computer science, agriculture, and related disciplines. In particular, we welcome work that addresses emerging challenges in science and technology and that has the potential for high impact and interdisciplinary interest.

• Article Types: You may submit full-length research articles, review papers, short communications, systematic reviews, case studies, conference proceedings, as well as editorial and perspective pieces.
• Open Access: TUJNAS is fully open access. All accepted papers will be freely available online immediately upon publication under a CC BY 4.0 license, maximizing their reach and citation potential.
• Publication Model: The accepted articles will be published in Volume 11, Issue 2 in December 2026.
• Peer Review: Submissions undergo our rigorous double-blind peer-review process. Decisions are usually made promptly by our international editorial team, and reviewers’ reports provide constructive feedback to improve the work.
• Fees: There are no fees to submit a manuscript. A modest article-processing charge applies only upon acceptance; this fee covers professional editing, hosting, and archiving. Waivers or discounts are available for eligible authors (for example, editorial board members publish for free). Editorial decisions are based solely on scientific quality, not on any fees.

Why publish with TUJNAS? Publishing in TUJNAS ensures that your work is peer-reviewed by experts and rapidly disseminated to a global audience. As an open-access journal, TUJNAS removes access barriers: your article will reach readers in academia, industry, and beyond without subscription limits. TUJNAS publishes two scheduled issues each year, in June and December. To accelerate dissemination, accepted articles may be published online first within the forthcoming scheduled issue after completion of editorial checks, production, DOI registration, and final approval. Online-first publication does not change the journal publication frequency: all articles are assigned to one of the two annual issues and remain part of the official issue record.

Submission Instructions: Authors should prepare manuscripts according to the Author Guidelines on the journal website and submit via the online system. Details on formatting, ethical policies, and publication fees can be found in the Journal’s “For Authors” section. For inquiries about submissions, contact the editorial office. We look forward to receiving your contributions and advancing science together in our next issue!

Important Dates: Submissions are welcome before the 15^th of November 2026; to be included in Vol. 11 No. 2 (December 2026), please submit by the early part of the second half of 2026.
