Submission of papers

Submission of a manuscript implies that it is not being considered contemporaneously for publication elsewhere. Submission of a manuscript implies the consent of all participating authors. All papers will be independently refereed by two reviewers. Authors are requested to include a list of three potential reviewers (with address e-mail and affiliations) during the manuscript submissions.

Types of contribution

Original research papers; review articles; short communications.


Original in English should be provided, in double-spaced typing on A4 pages. The author(s) is responsible for the correct English translation of the paper. Before chapter References put the name of the translator.

Each paper should be divided under the following headings in this order: (-) a title of the paper must be concise and should unambiguously reflect its contents; (-) the names and addresses of authors should follow the title with the author for correspondence marked and e-mail address provided if possible; (-) four or five keywords for the main topics of the paper; (-) an abstract not exceeding 150 words, reporting concisely on the major findings;

An introduction giving essential background with clearly stated objectives; (-) materials and methods with sufficient full experimental details to allow the work to be repeated. Sources of material must be given and statistical methods must be specified by references; (-) results and discussion may be presented together or separately. Results should be presented concisely; appropriate statistical data should be given. Discussion should cover the implications and consequences, not merely recapitulating the results;  (-) references must be listed alphabetically at the end of the article. For periodicals give: name(s) and initial(s) of the author(s), the year of publication, abbreviate journal title as in Chemical Abstracts, volume number, initial and final page numbers of article. For books: names and initials of all the authors, the year of publication, the name(s) of the editor(s) (if appropriate), the name of the publisher and the town, and initial and final page numbers. References in the text must be cited by name and year in parentheses.

Units and Abbreviations

SI units should be used. Abbreviations for units should be used only when long or unwieldy names occur frequently, and are newer in the title. They should be given at the first mention of the name. Currently recognized chemical nomenclature should be used, although commonly accepted trivial names may be used where there is no risk of ambiguity.

Figures, Mathematical Formulas, and Tables

Tables and Figures should be pasted after the text of the article along with their captions.
Mathematical and physical formulas should be presented in the MS Word formula editor.
Authors are encouraged to supply the electronic versions of the figures after the acceptance of the paper. Figure drawings should be submitted in vector graphics form (Corel, Excel, Statistica, Word documents). Figure drawings developed in other specialist applications should be saved in Windows Metafile (*.wmf) format that can be imported to Corel.
