Guide for authors

Publication in the Eurasian Physical Technical Journal is a direct reflection of the quality of the authors' research work and the reputation of the institution that supports them. Original research articles, as well as review articles with analytical descriptions of current problems in physical and technical sciences, are accepted for publication.

Authors are encouraged to submit research papers that have scientific novelty and practical value after careful reading and review. Make sure that the article material is structured and meets all of the requirements listed below. Submissions will be rejected and returned to the authors if they do not meet these requirements.

Scientific Article Scope and Content

A scientific article should contain the results of original scientific research previously unpublished and not intended for publication in other publications. Manuscript of the article should contain at least 75% of the original text.

In "Eurasian phys. tech. j." articles are published in English in 4 scientific areas of technical physics: Energy; Engineering; Materials Science; Physics and Astronomy. The corresponding author must indicate the Journal section in which the article will be published.

A scientific article, including a bibliography, should not exceed 10-12 pages of text, including tables, formulas, figures (no more than 10) and a list of references (no more than 20-25), typed on a computer in Microsoft Word.
