International Journal of Engineering and Natural Sciences (JIENS) aims to publish current-perspective, original and high-qualified research articles in any branch of engineering and natural sciences particularly those concerned with themes such as materials, chemistry, physical chemistry, physics and mathematics. All responsibility of the articles to be published in the journal belongs to the author (s). The authors must declare the novelty of the research and the accuracy of the results presented in the submitted articles. The submission is not published at any other publication and will not be submitted elsewhere before a decision is made by this journal. JIENS covers reports in three sections, namely Research Articles, Review Articles, and Letters to the Editor.
Research Articles: Articles involve original scientific studies in basic and applied science fields and they explain the important results in theoretical, computational and experimental ways.
Review Articles: Articles highlight recent progress in basic and applied science and evaluate techniques and applications in the state-of-the-art scientific studies, as well as the reports include the interpretation of the research results.
Letters to the Editor: Letters commenting on previously published articles are normally be sent to the editors to provide additional scientific contributions, comments and criticisms.
Language: Publication language can be Turkish and /or English. The manuscripts should be written in a clear and fluent manner with appropriate scientific and technical expressions. When the articles are written in Turkish, both Turkish and English abstract should be placed in the main text. When the articles are written in English, only English abstract is adequate.
Articles should not be included no longer needed or useful and well-known information, as well as featureless sources as references. Previously published data, formulas and results should be cited by referring their original papers. Nomenclature, abbreviations and symbols should be used in accordance with international standards. Abbreviations which are special to the articles and common for the relevant field should be indicated in parentheses in the first place their used. SI (Systemé International) units and abbreviations are accepted in the articles.
The manuscripts are required to comply with national and international ethic rules for publishing. Authors must pay attention to ICMJE (International Committee of Medcial Journal Editors) recommendations and COPE (Committee on Publication Ethics) guidelines, namely “International Standards for Editors and Authors”.
Format: Manuscripts must be prepared in accordance with the templates as follows:
The manuscripts must be uploaded in “.docx” extension.
2. Article Structure
Scaling: The page margins should be 2.5 cm (Right-Left-Above-Below). The margin values should not be changed in the template.
Title: A title should be comprehensive and understandable. The title should be written with Times New Roman (TNR) font in 14 size and it should be left aligned. The first letter should be written in capital letter and the rest are in lowercase. In Turkish articles, the relevant English title should be placed before the Turkish abstract. In terms of English title, the first letter should be capitalized, and should be written with TNR font in 12 size, as well as should be left aligned.
Author Names and Contacts: Double blind peer review system is applied by our journal on behalf of objective publishing, so the author names and contacts should be presented in first submission. Nevertheless, the number of authors should be arranged by using the structure in the template (First Author, Second Author…). The author names and contacts should be presented in the accepted submission. Without any abbreviations, the first letters of names and surnames are capitalized and the other letters are written in lowercase, and all names are written with TNR font in 10 size. The name line should be placed as left aligned under the title line. The titles of the authors should not be written before names. The contact information should be given in full-length. A letter superscript should be used in terms of different contacts. The contact information should be written with TNR font in 7 size and italic style. In addition, the corresponding author's phone and e-mail address should be written with TNR font in 7 size.
Keywords: Immediately after the abstract, it should be provided a maximum of 8 and a minimum of 3 keywords. They should be written with TNR font in 7 size and left aligned. The first letter of keywords should be in capital letter.
Abstract: Abstract should briefly state the purpose of the research, the principal results and major conclusions. In case of both Turkish and English versions, it should not exceed 250 words and it should be in one paragraph. It should be written with TNR font in 7 size and aligned on both sides.
Text: The main text of the manuscript should be written using TNR font in 10 size with 1.5 line spacing. Before paragraphs, line spacing should be set to 0 PT before spaces and 6 PT after spaces. The article should be divided into main sections with different titles and each section should be numbered. The titles should be written in Bold Font. In terms of main sections, the numbering should start from I (then II, III, …) and “Summary”, “Acknowledgments” and “References” should be not included in the section numbering. Considering the numbering of the related main section, secondary subsections should be numbered as 1.1, 1.2, 1.3, … and the first letters of the words placed the secondary titles should start with capital letters. Regarding the secondary subsections, tertiary subsections should be numbered as 1.1.1., 1.1.2., 1.1.3…For the tertiary subsections, only the first letter of the first word should be capitalized. Fourth subsections should be underlined. The format of the article is illustrated as follows:
It states the objectives of the work and provide an adequate background. In this section research subject should be explained avoiding giving a detailed literature survey or research results. References should not be given as group or sparse (eg [1-5] or [1, 2, 3, 5, 8]). The contribution of each source should be examined and stated in the text. Also, references should not be hyperlinked.
II. EXPERIMENTAL METHOD/THEORETICAL METHOD
In case of research driven by experimental study, test procedure / method should be explained in a clear way. If a theoretical study has been carried out, the theoretical method should be given in detail. If the method has been previously mentioned in published studies, the difference of the current study should be stated by referring to the previous studies.
2.1 Materials and Preparation Techniques
2.1.1. Characterization of materials
III. RESULTS AND DISCUSSION
Results should be clear and concise. Discussion parts should explore the significance of the results of the work by compared them with the literature.
The main conclusions of the study may be presented in a short and clear ways.
It can be given before the resources section at the end of the article. A example for “Acknowledgement Section”; This study was supported with Yalova University BAPKO Graduate Thesis Project (2018/YL/0016).
Since the evaluation of the articles is based on the Double Blind Review Process, the text of “Acknowledgments“ should be added after the acceptance of manuscript for the publication.
Reference citations in the text should be identified by numbers in square brackets. Some examples:
1. Negotiation research spans many disciplines .
2. This result was later contradicted by Becker and Seligman .
3. This effect has been widely studied [1-3, 7].
The list of references should only include works that are cited in the text and that have been published or accepted for publication. Personal communications and unpublished works should only be mentioned in the text.
The entries in the list should be numbered consecutively.
If available, please always include DOIs as full DOI links in your reference list (e.g. “https://doi.org/abc”).
