Author Guidelines


National and international ethical rules should be observed.

Because of our publishing policy, adaptation to research and publication ethics is an essential requirement.


Gazi University Journal of Science (GUJS) has a fully online submission and online reviewing system. This system offers authors the option of tracking by online based review process of their manuscripts. All manuscripts must be submitted with online from the system by registering.

The manuscripts submitted for the publication should correspond to the scope of The Gazi University Journal of Science (GUJS). The journal covers theoretical and some applied aspects of science and technology; it informs the reader of new trends in basic science and technology.

Contributions to the “Gazi University Journal of Science”(GUJS) will be published in English, and manuscripts must be submitted in that language. Either standard British or American spelling is acceptable, provided its use is consistent within the manuscript.

The article must conform to the template found on the Required Files page.


Initial Lay-out

This journal follows a double-blind reviewing procedure. Authors are therefore requested to submit:
A blinded manuscript without any author names and affiliations in the text. Self-identifying citations and references in the article text should be avoided.
A separate title page, containing title, all author names, affiliations, and the contact information (e-mail, telephone number and fax number) of the corresponding author. Any acknowledgements, disclosures, or funding information should also be included on this page.
The other headings should be written with uppercase letters starting from a new line. Other than the main heading, all headings should be written with lowercase letters except the first letter of the heading.The author to whom correspondence should be addressed must be indicated by an asterisk. Acceptable similarity rate for the article is ≤ 20%.  


Research papers and reviews begin with an abstract (250 words) which should comprise a brief factual account of the contents of the paper, with emphasis on new information. Abbreviations and jargon must not be used. The abstracts should be suitable for use by abstracting services without rewriting. Abstract for a maximum of 250 words should be placed after the address of the author and one blank line. After one blank line from the abstract Key Words be written italics.



Key words reflecting the major features of the work should be inserted, but not more than five.



This is the numbered part of the manuscript which may include the parts: 1. Introduction, 2. Experimental (Material and Methods) 3. Results and Discussion, 4. References. The text may include sub headings with the following numbering style (2.1, 2.2,…etc.). 



Every paper must have a concise introduction explaining the state of the art of the topic described, and stating clearly what is new in the paper now submitted.


Experimental (Material and Methods)

The experimental methods and the materials used should be described after the introductory paragraphs. Detailed technical descriptions should be restricted to one section of the paper, and not scattered throughout the text. Sufficient information should be given to allow any reasonably experienced worker to carry out the procedure. Detailed descriptions of well-known techniques and equipment are unnecessary, as are simple preparations of reagents or solutions, and lists of common materials. In writing, complete sentences should be used. If an ethics committee permission is required for the study, the ethics commission date-number should be indicated.


Results and Discussion

Preferably these should be treated together to avoid unnecessary repetition. Unsupported elaboration of hypotheses and verbose exposition of ideas should be avoided. Results and Discussion may be presented in different sections.


If any support is given to the work by an institution or a person, it should be indicated as acknowledgement in the manuscript. Acknowledgements should be kept as short as possible, and placed at the conclusion of the text.


Conflict of Interest

No conflict of interest was declared by the authors.

Figures and Tables

Figures, graphs, photographs and tables in JPG or TIFF format should be given inside (not a seperate page) the manuscript. The photographs should be scanned and submitted as original copies. All figures and tables should be numbered consecutively in Arabic numerals throughout the paper. Footnotes to tables should be with lower-case letters. Line drawings are preferable to photographs. Scanned graphs are less preferred and acceptable only if adequately resolved. Inscriptions should be clearly legible. Letters 2–3 mm high are recommended in the desired final size. Half-tone illustrations, if any, should be well contrasted and trimmed at right angles in the desired final size. Graphs should not be present in large format (e. g. A4 full size), but rather in a typical size of 6—8 cm.


Nomenclature, symbols and abbreviations

In general, the recommendations of the SI units should be followed. Symbols, formulas and equations should be written with great care, capitals and lower case letters being distinguished where necessary. Particular care should be taken in typing mathematical expressions containing superscripts and in proof-reading such equations.Mathematical expressions should be written by an equation editor (Word format) in 9 point size. Indices font should be 8 point size. Each equation in text should be numbered in parenthesis ( ). Unusual symbols employed for the first time should be defined by name in the left-hand margin. Abbreviations require definition when first used.


Note: Authors must suggest at least three potential reviewers from different geographical locations. These should be experts in their field, who will be able to provide an objective assessment of the manuscript. Any suggested peer reviewers should not have published with any of the authors of the manuscript within the past five years, should not be current collaborators, and should not be members of the same research institution. Suggested from you reviewers will be considered alongside potential reviewers recommended by the Editorial Board. Authors must add the name, address and e-mails of reviewers to the part of "Author Comments" during the submission of the manuscript.
