Author Guidelines

A. INTRODUCTION
Oktahedral Journal is an international journal covering theoretical and experimental aspects of
Chemistry. The journal publishes original research papers and review articles. The paper
published in this journal implies that the work described has not been, and will not be published
elsewhere, except in the abstract or as part of a lecture. 
The submitted manuscript should have relevance to basic and applied chemistry. Papers dealing
with environmental sciences, technological applications, or natural product-derived compounds
without any significance to the basic understanding of molecules or materials are not acceptable.
Routine synthesis of molecules or materials without presenting significant new synthetic routes,
structural parameters, and/or potential applications is not welcomed in this journal. Molecular
docking results must be accompanied by either extensive quantum-chemical-based calculations,
molecular dynamics simulations, or experimental work. Note that Chemical Engineering and
Chemical Education papers are out of scope from this journal. 

B. BEFORE YOU BEGIN
1. Ethics in Publishing
For information on Ethics in Publishing and Ethical guidelines for the journal's publication see
Ethic.

2. Conflict of interest
All authors are requested to disclose any actual or potential conflict of interest, including any
financial, personal, or other relationships with other people or organizations, within three years
of beginning the submitted work that could inappropriately influence or be perceived to
influence their work.

3. Submission declaration
Submission of an article implies that the work described has not been published previously
(except in the form of an abstract or as part of a published lecture or academic thesis), that it is
not under consideration for publication elsewhere, that its publication is approved by all authors
and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if
accepted, it will not be published elsewhere including electronically in the same form, in English
or in any other language, without the written consent of the copyright holder. Authors must
submit proof of manuscript plagiarism checking results using software like Turnitin, iThenticate,
etc. The proof must be submitted as a supplementary file along with the submitted manuscript
file.

4. Copyright
Upon acceptance of an article, authors automatically transfer the copyright to the journal.
Permission of the journal is required for resale or distribution outside the institution and for all
other derivative works, including compilations and translations. If excerpts from other
copyrighted works are included, the author(s) must obtain written permission from the copyright
owners and credit the source(s) in the article. 

5. Language
Please write your text in standard English (American English is required). Proofing tools/utilities
(spell and grammar checks) should be used. Authors are advised to have their papers
professionally edited for the English language if necessary.

6. Submission
The manuscript should be submitted by one of the authors through the online system. A
manuscript submitted by anyone other than one of the authors will not be processed for
publication. The submitter takes responsibility as a corresponding author during submission, the
peer review process, copyediting, and author proofreading. 

In submission, the submitter will be guided stepwise through creating and uploading the various
files. All correspondence, including notification of the Editor's decision and requests for revision,
takes place by e-mail and via the author's homepage, removing the need for a hard-copy paper
trail. When submitting a revised manuscript, please upload only the revised manuscript files. The
handling Editor has access to the original manuscript files; therefore, there is no need to upload
these files again along with the revised manuscript. 

C. PREPARATION AND SUBMISSION
1. Use of word-processing software
The file must be saved in the native format of the word processor used. All manuscripts should
be written in concise and clear English and suggested to be typed with full justification, singled
spaced for all contains, in Times New Roman 12, using no more than 20 pages for original
papers and 30 pages for reviews. Left and right margins should be 3.0 cm in length. Top margins
should be 4.0 cm and 3.0 cm for bottom. The title should be typed in Times New Roman 14
bold. The authors' names and addresses at which the research was done, should appear under the
title. Use Arabic numbers typed as a superscript to link authors to their addresses with an asterisk
to indicate the author(s) to whom correspondence should be addressed. Main headings (Abstract,
Introduction, Experimental, Results and Discussion, Conclusions) are typed in bold. Type all
headings aligned justify and lowercase except the first letter of the first word or any proper
name. The electronic text should be prepared in a way very similar to that of conventional
manuscripts. Do not import the figures into the text file, but indicate their approximate locations
directly in the electronic text and the manuscript. To avoid unnecessary errors, you are strongly
advised to use your word processor's "spell-check" and "grammar-check" functions.

2. Article structure
Introduction
State the objectives of the work and provide an adequate background, avoiding a detailed
literature survey or a summary of the results. 
Methods
Provide sufficient detail to allow the work to be reproduced, including Materials,
Instrumentation, and procedures. A reference should indicate published methods; only relevant
modifications should be described.  
Results and discussion
Results should be clear and concise. This should explore the significance of the results of the
work, not repeat them. A combined Results and Discussion section is often appropriate. A
comparison of the results and the research results reported in any previously published articles is
essential to be discussed. Avoid extensive citations and discussion of published literature. 
Conclusions
The study's main conclusions may be presented in a short Conclusions section, which may stand
alone or form a subsection of a Discussion or Results and Discussion section. 

Supplementary
If there is more than one supplementary, they should be identified as S1, S2, etc. Formulas,
equations, tables, and figures should be given separate sub-sections. All supplementary should be
combined within a single file.

Essential title page information

• Title. Concise and informative. Titles are often used in information retrieval systems. Avoid abbreviations and formulae where possible.
• Author names and affiliations. Where the family name may be ambiguous (e.g., a double name), please indicate this clearly. Present the authors' affiliation addresses (where the actual work was done) below the names. Indicate all affiliations with a lower-case superscript letter immediately after the author's name and in front of the appropriate address. Provide the full postal address of each affiliation, including the country name and, if available, the e-mail address of each author.
• Corresponding author. Clearly indicate who will handle correspondence at all stages of refereeing and publication, as well as post-publication. Ensure that telephone and fax numbers (with country and area code) are provided in addition to the e-mail address and the complete postal address.
• Present/permanent address. If an author has moved since the work described in the article was done or was visiting at the time, a "Present address" (or "Permanent address") may be indicated as a footnote to that author's name. The address at which the author actually did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

 3. Abstract
An abstract of at most 250 words is required. The abstract should state briefly the purpose of the
research, the principal results, and major conclusions. An abstract is often presented introduction
includes the aim of the study, the principal results and major conclusions. Subjects/objects of the
study, methods and design, research period should be written briefly. Results or findings of the
study are clearly described. Summary of the study is explained. Abbreviations should be
avoided, but if essential, they must be defined at their first mention.

4. Keywords
Keywords is about 3-5 words, covering scientific and local name (if any), research theme, and
special methods which used (no abbreviation) and written down in an alphabetical order to help
indexing.  

5. Abbreviations
Define abbreviations that are not standard in this field in a footnote to be placed on the article's
first page. Such unavoidable abbreviations in the abstract must be defined at their first mention
there and in the footnote. Ensure consistency of abbreviations throughout the article.

6. Acknowledgments
Collate acknowledgments in a separate section at the end of the article before the references and
do not, therefore, include them on the title page as a footnote to the title or otherwise. List here those individuals who provided help during the research (e.g., language help, writing assistance
proofreading the article, etc.).

7. Nomenclature and Units
Follow internationally accepted rules and conventions: use the international system of units (SI).
If other quantities are mentioned, give their equivalent in SI. You are urged to consult the
International Union of Pure and Applied Chemistry (IUPAC). For further information, please
visit http://www.iupac.org.

8. Footnotes
Footnotes should be used sparingly. Number them consecutively throughout the article, using
superscript Arabic numbers. Many word processors build footnotes into the text, and this feature
may be used. Should this not be the case, indicate the position of footnotes in the text and present
the footnotes themselves separately at the end of the article. Do not include footnotes in the
Reference list.

9. Artwork
General points

• Make sure you use uniform lettering and sizing of your original artwork.
• Save text in illustrations as "graphics" or enclose the font.
• Only use Arial font in your illustrations.
• Number the illustrations according to their sequence in the text.
• Use a logical naming convention for your artwork files.
• Provide captions to illustrations separately.
• Produce images near the desired size of the printed version. 

Formats
Regardless of the application used, when your electronic artwork is finalized, please "save as" or
convert the images to one of the following formats (note the resolution requirements for line
drawings, halftones, and line/halftone combinations given below):
EPS: Vector drawings. Embed the font or save the text as "graphics". 
TIFF: color or grayscale photographs (halftones): always use a minimum of 300 dpi. 
TIFF: Bitmapped line drawings: use a minimum of 1000 dpi. 
TIFF: Combinations of bitmapped line/half-tone (color or grayscale): a minimum of 500 dpi is
required. 
DOC, XLS, or PPT: If your electronic artwork is created in any of these Microsoft Office,
applications please supply "as is".  

Color artwork
Please make sure that artwork files are in an acceptable format (TIFF, EPS, or MS Office files)
and with the correct resolution. If, together with your accepted article, you submit usable color
figures then Oktahedral Journal will ensure, that these figures will appear in color on the Web
regardless of whether or not these illustrations are reproduced in color in the printed version. For
color reproduction in print, you will receive information regarding the costs from Oktahedral
Journal after receipt of your accepted article. 

Figure captions
Ensure that each illustration has a caption, and supply them separately. A caption should
comprise a brief title (not on the figure itself) and a description of the illustration. Keep text in
the illustrations themselves to a minimum but explain all symbols and abbreviations used.

10. Tables
Number tables consecutively in accordance with their appearance in the text. Place footnotes to
tables below the table body and indicate them with superscript lowercase letters. Avoid vertical
rules. Be sparing in the use of tables and ensure that the data presented in tables do not duplicate
results described elsewhere in the article.

11. References
Citation in text
Please ensure that every reference cited in the text is also present in the reference list (and vice
versa). Any references cited in the abstract must be given in full. Unpublished results and
personal communications are not recommended in the reference list but may be mentioned in the
text. If these references are included in the reference list, they should follow the standard
reference style of the journal and should include a substitution of the publication date with either
"Unpublished results" or "Personal communication" Citation of a reference as "in press" implies
that the item has been accepted for publication. 
Web references
The full URL and the date when the reference was last accessed should be given as a minimum.
Any further information should also be given if known (DOI, author names, dates, reference to a
source publication, etc.). Web references can be listed separately (e.g., after the reference list)
under a different heading if desired or can be included in the reference list. 
Reference style
Text: Indicate references by number(s) in square brackets in line with the text. The actual authors
can be referred to, but the reference number(s) must always be given.  
Example: "..... as demonstrated [3,6]. Barnaby and Jones [8] obtained a different result ...." 
List: Number the references (numbers in square brackets) in the list in the order in which they
appear in the text.
