• Universal Decimal Classification (UDC) code;

• heading (according to subject heading list);

• title;

• data on author(s);

• abstract;

• keywords;

• text of the article (including Introduction, Research Methods, Main Part, Analysis of Results, Conclusion; Acknowledgements);

• all tables and figures have numbers (e.g. Table 1, Figure 1) and names (e.g. Table 1. Results of electrochemical tests). All digital and letter symbols should be explained in the figure legend or in the footnote.;

• references should include full bibliographic information.

1.2. The first page includes the following information: UDC, heading, title of the article (without acronyms and abbreviations), data on author(s): first and second names, position, department, institution, academic degree and titles, e-mail, city, country. Additionally, phone number and full postal address of a corresponding author are provided for editors to remove questions when working on the article.

1.3. Abstract may not be less than 200 and more than 250 words, and should not include references. It should succinctly describe the study, including brief description of all parts of the article structure: introduction, purposes and objectives, research methods, main part, analysis of results, and conclusion.

1.4. Keywords should reflect the main content of the article. Provide a maximum of 6 keywords, avoiding general and plural terms and multiple concepts (for example, 'and', 'of'). If possible, do not repeat the title and abstract terms, use the terms from the article text. Only abbreviations firmly established in the field may be eligible. The keywords will be used for indexing purposes.

1.5. Authors should use modern English scientific terminology, avoiding terms transcribed from foreign words. Words and names abbreviations except for the common measures, physical and mathematical variables and terms are allowed only with the full name initial indication. Narrowly specialized terms should be defined.

1.6. The article should be carefully verified by the author. In mathematical expressions, all variables and sub-indexes should be clearly marked: italic type for Latin letters, Roman type for Greek letters, superscripts and subscripts, capital and lowercase letters, letters and numbers similar by writing.
