Guide for Authors

Please Note: Since the beginning of 2018, it is mandatory for all authors to have a free ORCID ID.

Please Note: when submitting the manuscript, the Copyright agreement, and Conflicts of Interest Statement must also be sent.

To write your manuscript, you can download the original article MS-word template here.

Main text: Manuscripts should be written in English. For regular research Articles, submitted manuscripts should not exceed a total of 30 pages including Title, Authors, Affiliations, Abstract, Keywords, Main text (including figures and tables), Acknowledgements, Nomenclature, References, Appendix (basis: Times New Roman Font, Size 11, 1.5 lines space, 1 inch by inch margins). Exceptions can be made with approved justification. It is preferred that figures and tables are embedded within the main body of the text. There may be more than one figure or table per page. Authors have to either use the spell-checking facility of their word processor or proofread the manuscript themselves before submission of the paper.

Main text: Divide your manuscript into clearly defined and numbered sections. Subsections should be numbered 1.1 (then 1.1.1, 1.1.2, …), 1.2, etc. (the abstract is not included in section numbering). Use this numbering also for internal cross-referencing: do not just refer to 'the text'. Any subsection may be given a brief heading. Each heading should appear on its own separate line. (Use Times New Roman Font, Size 11, Bold; Size 11, Italic, respectively for sections and subsections headings and Size 11 for typing the text).

Introduction: State the objectives of the work and provide an adequate background, avoiding a detailed literature survey or a summary of the results.

Material and methods: Provide sufficient details to allow the work to be reproduced by an independent researcher. Methods that are already published should be summarized, and indicated by a reference. If quoting directly from a previously published method, use quotation marks and also cite the source. Any modifications to existing methods should also be described.

Results and Discussion: Results should be clear and concise. Avoid extensive citations and discussion of published literature.

Conclusions: The main conclusions of the study may be presented in a short Conclusions section.

Acknowledgments: All acknowledgments (if any) should be included at the very end of the manuscript before the references. Anyone who made a contribution to the research or manuscript (e.g., providing language help, writing assistance, or proofreading the article, etc.), but who is not a listed author, should be acknowledged (with their permission).

Nomenclature: Manuscripts with many symbols may benefit from a nomenclature list that defines all symbols at the end of the manuscript. Symbols should be either defined in the text or entirely placed at the end of the text and immediately before the ‘References’ section. Nomenclature entries are listed alphabetically (capital letters before lowercase), in the following order: regular letters, Greek letters, numerals, and special symbols. Units of measure should be included in definitions where appropriate. Individual headings may be used to distinguish subscripts and superscripts from regular symbols.

Supplementary materials: Supplementary materials are the additional parts of a manuscript, such as audio files, video clips, or datasets that might be of interest to readers. Authors can submit one file of supplementary material along with their manuscript through the manuscript submission system. If there is more than one file, they can be uploaded as a .ZIP file. A section titled supplementary material should be included before the references list with a concise description for each supplementary material file. Supplementary materials are not modified by our production team. The authors are responsible for providing the final supplementary material files that will be published along with the article.

Appendices: If there is more than one appendix, they should be identified as A, B, etc. Formulae and equations in appendices should be given separate numbering: Eq. (A.1), Eq. (A.2), etc.; in a subsequent appendix, Eq. (B.1), and so on. Similarly, for tables and figures: Table A.1; Fig. A.1, etc.

Contributed manuscripts should be arranged in the following order:

Title: Concise and informative. The title should emphasize the principal objective. Avoid abbreviations and formulae where possible. (Use Times New Roman Font, Size 20, capitalize the first letter of every word)

Author names and affiliations: Authors' names follow the title in the next line. Please clearly indicate each author's given name(s) and family name(s) and check that all names are accurately spelled. Present the authors' affiliation addresses (where the actual work was done) below the names. On a separate line, mention the authors’ affiliations (with addresses) where the research was done. Use an asterisk (*) to distinguish the corresponding author with a footnote containing an e-mail address, phone, and fax number of the person. Clearly indicate who will handle correspondence at all stages of refereeing and publication, also post-publication. This responsibility includes answering any future queries about Methodology and Materials. Ensure that the e-mail address is given and that contact details are kept up to date by the corresponding author. (Use Times New Roman Font, Size 17; Size 9, respectively for authors' names and affiliations)

Highlights: Highlights are voluntary for this journal. However, it can help increase the discoverability of your paper via search engines. They consist of a short collection of bullet points that capture the novel results of your research as well as new methods that were used during the study (if any).

Abstract: The abstract should state the objective and conclusions of the research concisely in a single paragraph of no more than 300 words. For research articles, abstracts should give a pertinent overview of the work. We strongly encourage authors to use the following style of structured abstracts, but without headings: (1) Background: Place the question addressed in a broad context and highlight the purpose of the study; (2) Methods: briefly describe the main methods or treatments applied; (3) Results: summarize the article’s main findings; (4) Conclusions: indicate the main conclusions or interpretations. (Use Times New Roman Font, Size 10)

Keywords: Select a maximum of five keywords from your article that best describe the topic. These words will be used for search and retrieval, as well as indexing. (Use Times New Roman Font, Size 10, Italic)

Table: All tables should be numbered with Arabic numerals. Every table should have a caption. Captions must be typed up in each table. Use each Table of your manuscript in the appropriate place and after referring to it. Do not give them in a separate file(s) or at the end of the manuscript. (Use Times New Roman Font, Size 10; Size 9, respectively for captions and table contents)

Figure: All figures should be numbered with Arabic numerals (1, 2, 3…), consecutively. Every figure should have a caption, which is located under each Figure. All photographs, schemas, graphs, and diagrams are referred to as figures. Line drawings should be good-quality scans or true electronic output. Low-quality scans are not acceptable. The figures should be carefully designed and prepared in a form suitable for direct reproduction. All lettering should be prepared for a size that can be read after reduction. Label the axes outside the graph properly. Use each Figure of your manuscript in the appropriate place and after referring to it. Do not give them in a separate file(s) or at the end of the manuscript. (Use Times New Roman Font, Size 10; Size 9, respectively for captions and figure’s contents)

Math Formulae (Equations): Please submit math equations as editable text and not as images. Equations and formulae should be typed in Math type and numbered consecutively with Arabic numerals in parentheses on the right-hand side of the page (if referred to explicitly in the text). They should also be separated from the surrounding text by one space.

Declaration of conflicting interests: All authors must disclose any financial and personal relationships with other people or organizations that could inappropriately influence (bias) their work. Examples of potential conflicts of interest include employment, consultancies, stock ownership, honoraria, paid expert testimony, patent applications/registrations, and grants or other funding. Authors should complete the Conflicts of Interest Statement using this template and upload it to the submission system.

References: Should be listed in numerical order in the order in which they are cited in the text and must be listed at the end of the paper. Do not begin them on a new page unless this is necessary. Authors should ensure that every reference in the text appears in the list of references and vice versa. The numbers must use for reference within the main text in brackets: [ ] e.g. [1] or [2, 3]. Give complete information, including names of all authors, titles of the article and periodicals or books, numbers of pages, volumes, issues, publication years, and DOI if it exists.

Reference management software: Chemical Process Design journal has its reference template available in the most popular reference management software product such as Endnote. Using citation plug-ins from this product, authors only need to select the appropriate journal template when preparing their papers, after which citations and bibliographies will be automatically formatted in the journal's style.

Reference style: Authors should use the following style to format their references:
