Declaration of generative AI in scientific writing

The below guidance only refers to the writing process, and not to the use of AI tools to analyze and draw insights from data as part of the research process. Where authors use generative artificial intelligence (AI) and AI-assisted technologies in the writing process, authors should only use these technologies to improve readability and language. Applying the technology should be done with human oversight and control, and authors should carefully review and edit the result, as AI can generate authoritative-sounding output that can be incorrect, incomplete, or biased. AI and AI-assisted technologies should not be listed as an author or co-author, or be cited as an author. Authorship implies responsibilities and tasks that can only be attributed to and performed by humans.

Authors should disclose in their manuscript the use of AI and AI-assisted technologies in the writing process by following the instructions below. A statement will appear in the published work. Please note that authors are ultimately responsible and accountable for the contents of the work.

Disclosure instructions
Authors must disclose the use of generative AI and AI-assisted technologies in the writing process by adding a statement at the end of their manuscript in the core manuscript file, before the References list. The statement should be placed in a new section entitled ‘Declaration of Generative AI and AI-assisted technologies in the writing process’.

Statement: During the preparation of this work the author(s) used [NAME TOOL / SERVICE] in order to [REASON]. After using this tool/service, the author(s) reviewed and edited the content as needed and take(s) full responsibility for the content of the publication.

This declaration does not apply to the use of basic tools for checking grammar, spelling, references, etc. If there is nothing to disclose, there is no need to add a statement.

Review process

The objective of JChPE is to provide constructive feedback on submitted papers and publish high-quality papers within a very short time. You may be requested by the Editor to submit a revision. Please submit the revised version of the manuscript at your earliest convenience to help us make the review process as short as possible.

In terms of review, the policy of JChPE is to review all submitted articles in a double-blind method. It means neither authors nor reviewers know each other’s identities so that each manuscript would be reviewed fairly and independently.


Authors are invited to suggest the names of five persons who are qualified to serve as reviewers. Please provide complete contact information, including an institutional e-mail address for each of the suggested reviewers.

Please note that suggested reviewers should have a great understanding and knowledge of the research area. Consider not suggesting collaborators, colleagues, and researchers at your institution, former advisors, or advisees. It must be noted that the final decision on the reviewers would be the Editor's choice, but your help is appreciated and could speed up the choice of appropriate reviewers.


The journal language is English. British or American English spelling and terminology may be used (but not a mixture of these). We appreciate any efforts that ensure the language before submission. This will greatly improve the legibility of your paper if English is not your first language.


Proofs will be sent to the corresponding author by e-mail. Your response, with or without corrections, should be sent within 72 hours.

Also, the institutional e-mail and phone number of the corresponding author should be written in the footnote of the title page.


Please provide a short abstract of 150 to 250 words. The abstract is often presented separately; so it should not contain any undefined abbreviations or references. It should represent the purpose and novelty of the research, the main findings, and the results.


Please provide 5 to 7 keywords in British or American English spelling. To allow independent retrieval through the internet, please include appropriate keywords (avoid general and plural terms and multiple concepts) in alphabetical order, separated by commas.

Manuscript Main File Structure

The manuscript, including the abstract, keywords, the main body of the article, all the figures and tables, conclusion, acknowledgment, nomenclature, appendices, and references, should be typed in a one-column page with a single line space in international A4 paper size. The right, left, up, and down margins should be 2.5 cm (1 inch). The article should be written in Times New Roman of 12-point in MS Word. Typical papers should not exceed 7500 words or 12 journal pages.


Authors are encouraged to use appropriate headings and subheadings in the main body of the manuscript. Headings must be numbered. Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Use the following guidelines for headings:

  • First level: Times New Roman bold of 14-point font (Heading)
  • Second level: Times New Roman bold of 12-point font (Heading)
  • Third level: Times New Roman italic of 12-point font ( Heading)

Recommended section titles for the first level of headings would be Introduction, Experiments and/or Theory, Results and Discussion, and Conclusion.


All figures should be of high quality and numbered consecutively (1, 2, etc.). Multipart figures should be labeled with lowercase letters (a, b, c, etc.). Please insert keys and scale bars directly in the figures. The resolution of the figures must at least be 300 dpi. Figures that are prepared by Excel should be sent along with their source of data. Each figure should stand alone.

Refer to a figure in the text as 'Fig.' and note that it is placed next to the relevant text in the manuscript. Please provide a caption for each figure using Times New Roman in 11-point font.


Tables should be numbered consecutively (1, 2, etc.). In tables, footnotes are preferable to the use of long explanatory material in either the heading or body of the table. Such explanatory footnotes should be placed immediately below the table.

Refer to a table in the text as 'Table' and note that it is placed next to the relevant text in the manuscript. Please provide a caption for each table using Times New Roman in 11-point font.


Equations should be numbered consecutively (1, 2, etc.). Please submit math equations as editable text and not as images.

Refer to an equation in the text as 'Eq.' and note that it is placed next to the relevant text in the manuscript.


As a journal for a general chemical engineering audience, JChPE uses SI units for unambiguous and widely accessible writing. Authors may include alternate measurements along with SI units, e.g. "0.15 g/g (15 mass %)."


Symbols are defined in the nomenclature, in the order symbol – definition (unit), alphabetically. Dimensionless symbols do not require a unit. Definitions are in the lowercase text, except for proper names. An example would be:




pressure (pa)


Reynolds number

Greek letter symbols must be listed immediately after the list of Roman symbols in a separate subsection entitled “Greek Letters” in alphabetic order.


In-text citations to Reference sources must be numbered consecutively in square brackets (e.g., [1]). Multiple references are each numbered with separate brackets (e.g. [2, 5, 4–6]).

International Diversity of its Authorship


Authorship is a way of making explicit both credit and responsibility for the contents of published articles. Credit and responsibility are inseparable. The guiding principle for authorship decisions is to present an honest account of what took place. Criteria for authorship apply to all intellectual products, including print and electronic publications of words, data, and images. Journals should make their own policies on authorship transparent and accessible. Authorship confers credit and has important academic, social, and financial implications. Authorship also implies responsibility and accountability for published work. The contributors who have made substantive intellectual contributions to a paper are given credit as authors, but contributors credited as authors understand their role in taking responsibility and being accountable for what is published. Because authorship does not communicate what contributions qualify an individual to be an author, Editors are strongly encouraged to develop and implement a contributorship policy, as well as a policy that identifies who is responsible for the integrity of the work as a whole. Such policies remove much of the ambiguity surrounding contributions but leave unresolved the question of the quantity and quality of contribution that qualify an individual for authorship.

Changes to Authorship

After the manuscript is submitted or accepted for publication, the corresponding author is required to send a request through the signed change of authorship form to add or remove an author or to rearrange the author names of the submitted/accepted manuscript. In order to download the change of authorship form click here.

Criteria for Authorship

Everyone who has made substantial intellectual contributions to the study on which the article is based (for example, to the research question, design, analysis, interpretation, and written description) should be an author. Only an individual who has made substantial intellectual contributions should be an author. Performing technical services, translating text, identifying patients for study, supplying materials, and providing funding or administrative oversight over facilities where the work was done are not, in themselves, sufficient for authorship, although these contributions may be acknowledged in the manuscript. One author (a “guarantor”) should take responsibility for the integrity of the work as a whole. Often this is the corresponding author, the one who sends in the manuscript and receives reviews, but other authors can have this role. All authors should approve the final version of the manuscript.  It is preferable that all authors be familiar with all aspects of the work. However, modern research is often done in teams with complementary expertise so every author may not be equally familiar with all aspects of the work. Therefore, some authors’ contributions may be limited to specific aspects of the work as a whole.

Number of Authors

Editors should not arbitrarily limit the number of authors. There are legitimate reasons for multiple authors in some kinds of research, such as multi-center, randomized controlled trials. In these situations, a subset of authors may be listed with the title, with the notation that they have prepared the manuscript on behalf of all contributors, who are then listed in an appendix to the published article. Alternatively, a “corporate” author (e.g., a “Group” name) representing all authors in a named study may be listed, as long as one investigator takes responsibility for the work as a whole. In either case, all individuals listed as authors should meet the criteria for authorship whether or not they are listed explicitly on the byline. If editors believe the number of authors is unusually large, relative to the scope and complexity of the work, they can ask for a detailed description of each author’s contributions to the work. If some do not meet the criteria for authorship, editors can require that their names be removed as a condition of publication. 

Order of Authorship

The authors themselves should decide the order in which authors are listed in an article. No one else knows as well as they do their respective contributions and the agreements they have made among themselves. Many different criteria are used to decide the order of authorship. Among these are relative contributions to the work and, in situations where all authors have contributed equally, alphabetical or random order. Readers cannot know, and should not assume, the meaning of the order of authorship unless the approach to assigning order has been described by the authors. Authors may want to include with their manuscript a description of how the order was decided. If so, editors should welcome this information and publish it with the manuscript.

Authorship Disputes

Disputes about authorship are best settled at the local level before the journal reviews the manuscript. However, at their discretion editors may become involved in resolving authorship disputes. Changes in authorship at any stage of manuscript review, revision, or acceptance should be accompanied by a written request and explanation from all of the original authors.


  • Editors of the Journal reserve the right to accept, reject, and edit any article at any stage, if necessary.
  • The authors are responsible for the content of the contribution.
  • The submitted materials may be considered for inclusion but cannot be returned.
