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 manuscripts should be written Times New Roman font, 12 point size and with 1,5 line spacing. Text pages should be numbered consecutively. The graphs and tables must be inserted into the text pages. Please do not use footnotes. The preferred letter font is Times New Roman of 12 pt.

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 front cover page should be prepared for the manuscript as follows: title of the manuscript, name, surname and addresses of the authors without statement of the titles (address: University / Organization, Faculty, Department, Postal code, City, Country, e-mail), indication of the corresponding author.
The author to whom correspondence should be addressed must be indicated by an asterisk. Acknowledgements of financial support should be included at the end of the paper.
Research papers and reviews begin with an abstract (100 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 100 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 and contain at least 3 words. should

The text may include sub headings with the following numbering style (2.1, 2.2,…etc.). The minimum and maximum number of pages should be 2 and 15 respectively. If necessary the advisory board may increase the maximum.
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.
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.
Results and Discussion
