7. Manuscript Preparation Guidelines

7.1. General Organization of Paper

The paper will be published in EJChE after the peer-reviewed process and decided as “Accepted” by Editors. The final paper layout will be reproduced by the Editorial Office of EJChE. The final paper layout in PDF type, known as “Uncorrected Proof” should be corrected by Author before published.

Manuscript submitted to this journal should follow the heading below, except for the review article: Title; Authors Name; Authors Affiliation; Abstract; Keywords; Introduction; Materials and Methods; Results and Discussion; Conclusions; Acknowledgments; and References. 

7.2. Paper Title

This is your opportunity to attract the reader’s attention. Remember that readers are the potential authors who will cite your article. Identify the main issue of the paper within the title. Begin with the subject or highlight the idea of the paper. The title should be accurate, unambiguous, specific, and complete. Do not contain infrequently-used abbreviations.

7.3. Authors Name and Affiliations

Write Author(s) names without a title and professional positions, such as: Prof, Dr, Production Manager, etc. Do not abbreviate your last/family name. Always give your First and Last names (should be at least 2 (two) words). Write a clear affiliation of all Authors. Affiliation includes the name of department/unit, (faculty), the name of the university, address, country. Please indicate Corresponding Author (include email address) by adding an asterisk (*) in superscript behind the name.

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 did the work must be retained as the main, affiliation address. Superscript Arabic numerals are used for such footnotes.

7.4. Abstract and Keywords

An abstract should stand alone, which means that no citation and figures and equation format in the abstract. Consider it the advertisement for your article. The abstract should tell the prospective reader what you did and highlight the key findings. Avoid using technical jargon and uncommon abbreviations. You must be accurate, brief, clear and specific. Use words that reflect the precise meaning. The abstract should be precise and honest. Please follow the word limitations (150‐200 words).

The abstract must contain: backgrounds (if any, maximum 2-3 sentences), short clear objectives, short methods, final results or findings, and conclusion.

Keywords are the labels of your manuscript and critical to correct indexing and searching. Therefore the keywords should represent the content and highlight of your article. Use only those abbreviations that are firmly established in the field. e.g. DNA. Each word/phrase in keyword should be separated by a semicolon (;), not a comma (,).

7.5. Introduction

In the Introduction, the Authors should state the objectives of the work at the end of the introduction section. Before the objective, Authors should provide an adequate background (maximum 1 paragraph), and very short literatures survey/review in order to record the existing solutions/method, to show which is the best of previous researches, to show the main limitation of the previous researches, to show what do you hope to achieve (to solve the limitation), and to show the scientific merit or novelties of the paper. Avoid a detailed literature survey or a summary of the results. Do not describe the literature survey/review as author by author, but should be presented as a group per method or topic reviewed which refers to some pieces of literature. Before the objectives and after the literature review, the author must state the gap analysis or novelties statements to show why does this paper is important and what is a unique idea of this paper compared to other previous researchers' suggestions.

One of the examples of novelty statement or the gap analysis statement at the end of Introduction section (after state of the art of previous research survey):

“........ (short summary of background)....... .....(put here state of the art or overview of previous researches similar to this research).............. A few researchers focused on ....... There have been limited studies concerned on ........ Therefore, this research intends to ................. The objectives of this research are .........”.

or 

“........ (short summary of background)....... .....(put here state of the art or overview of previous researches similar to this research).............. A few researchers focused on ....... There is no researcher concerned on ........ Therefore, this research focuses on ................. Therefore, this research is aimed to .........”.

etc.

7.6. Materials and Methods

Materials and methods should make readers be able to reproduce the experiment. Provide sufficient detail to allow the work to be reproduced. Methods already published should be indicated by a reference: only relevant modifications should be described. Do not repeat the details of established methods. For the chemicals, please provide details of brand and purity (example: CaO (Merck, 99.5%)) first, and state the concentration of chemicals in the procedure of the experiment.

7.7. Results and Discussion

The results should be clear and concise. The results should summarize (scientific) findings rather than providing data in great detail. Please highlight the differences between your results or findings and the previous publications by other researchers. The discussion should explore the significance of the results of the work, not repeat them. A combined Results and Discussion section is often appropriate. Avoid extensive citations and discussion of published literature.

In the discussion, it is the most important section of your article. Here you get the chance to sell your data. Make the discussion corresponding to the results, but do not reiterate the results. Often should begin with a brief summary of the main scientific findings (not experimental results).

The following components should be covered in discussion:

• How do your results relate to the original question or objectives outlined in the Introduction section? What is your finding of research? (what/how)? 
• Do you provide interpretation scientifically for each of your results or findings presented? This scientific interpretation must be supported by valid analysis and characterization (why)? 
• Are your results consistent with what other investigators have reported (what else)? Or are there any differences?

7.8. Conclusions

Conclusions should only answer the objectives of the research. Tells how your work advances the field from the present state of knowledge. Without clear Conclusions, reviewers and readers will find it difficult to judge the work, and whether or not it merits publication in the journal. Do not repeat the Abstract, or just list experimental results. Provide a clear scientific justification for your work, and indicate possible applications and extensions. This conclusion should be provided as a paragraph. You should also suggest future experiments and/or point out those that are underway.

 7.9. Acknowledgment

Recognize those who helped in the research, especially funding supporters of your research financially. Include individuals who have assisted you in your study: Advisors, Financial supporters, or may another supporter, i.e. Proofreaders, Typists, and Suppliers, who may have given materials. Do not acknowledge one of the authors' names.

7.10. Citations and References

Cite the main scientific publications on which your work is based. Cite only items that you have read. Do not inflate the manuscript with too many references. Avoid excessive self‐citations. Avoid excessive citations of publications from the same region. Check each reference against the original source (author name, volume, issue, year, DOI Number). Use other published articles in the same journal as models.

Citation within the body text of the article to reference(s) must follow the numbering system. References must be presented sequentially and sorted to start from first cited reference.

Example:

"Understanding the way by which a nanofiller affects theviscoelastic properties of dense polymer systems is based on the theory of polymer entanglements. These entanglements can form between neighboring polymer chains [1] as well as between the polymer and the nanofiller [2-4]. Adding nanofiller to a polymer matrix alters its viscoelastic behavior due to the formation of additional entanglements between the particles and the polymer chains, thereby enhancing the stiffness of the polymer matrix. While attractive intermolecular forces between the matrix and filler do contribute to the viscoelastic behavior of nanocomposites, size, shape and aspect ratio of the nanofillers also have significant influence on reinforcing effects [4-6] and the existence of molecular attraction between the matrix and filler is not required for reinforcement to occur[7]".

All publications cited in the text should be included as a list of references. References are sequentially numbered as they appear in the text. Reference numbers are indicated in square brackets. 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 maybe 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.

As a minimum, the full URL should be given and the date when the reference was last accessed. Any further information, if known (DOI, author names, dates, a reference to a source publication, etc.), should also be given. 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.

Please ensure that the words 'this issue' are added to any references in the list (and any citations in the text) to other articles in the same Special Issue.

We strongly recommend the authors to use Mendeley to edit citation format and bibliography style into Equlibrium’s style. The Author can learn how to insert Equilibrium’s style to Mendeley database here or download XML file.

7.11. References 

• Expect a minimum of 10 references primarily with a minimum 80% to journal papers.
• Use new references from the recent 10 years back since the paper is submitted.
• Citation within body text of the article to reference(s) must follow numbering system ("..... [1], ...... [2-3], etc.") which should be started from references cited first.
