The content, aim and scope of the proposals have to comply with the main topics of the journal, i.e. discuss at least one of the four main areas, namely: • New Advanced (Nano) Materials • Environment & Water Processing (including circular economy) • Biochemical & Biomedical Engineering (including pharmaceuticals) • Climate & Energy (including energy conversion & storage, electrification, decarbonization)

Chemical and Process Engineering: New Frontiers publishes: i) experimental and theoretical research papers, ii) short communications, iii) critical reviews, and iv) perspective articles. Each publication form is peer-reviewed by at least two independent referees.

New Submissions

Manuscripts are submitted for publication via Editorial System. When writing a manuscript, you may choose to submit it as a single Word file to be used in the refereeing process. The manuscript needs to be written in a clear way. The minimum requirements are: • Please use clear fonts, at least 12 points large, with at least 1.5-line spacing. • Figures should be placed in relevant places within the manuscript. All figures and tables should be numbered and provided with appropriate caption and legend, if necessary.

Language requirements

• Use Simple Past to talk about your experiment and your results as they were finished before you wrote the paper. Use Simple Past to describe what you did. Example: Two samples were taken. Temperature increased to 200K at the end of the process. • Use Simple Present to refer to figures and tables. Example: Table 2 shows nitrogen concentration changes in the process. • Use Simple Present to talk about your conclusions. You move here from describing your results to stating what is generally true. Example: The process is caused by changes of nitrogen concentration. • Capitalise words like ‘Table 2’, ‘Equation 11’. • If a sentence is longer than three lines, break down your writing into logically divided parts (paragraphs). Start a new paragraph to discuss a new concept. • Check noun/verb agreement (singular/plural). • It is fine to choose either British or American English but you should avoid mixing the two. • Avoid empty language (it is worth pointing out that, etc.).

Revised Submission

After the first revision, authors will be requested to put their paper in the correct format, using the below guidelines and template for articles.

Manuscript outline

1. Header details a. Title, b. Names (first name and further initials) and surnames of authors, c. Institution(s) (affiliation), d. Address(es) of authors, e. ORCID number of all authors. f. Information about the corresponding author: name and surname, email address.

2. Abstract – should contain a short summary of the proposed paper. In the maximum of 200 words the authors should present the main assumptions, results and conclusions drawn from the presented study.

3. Keywords – up to 5 characteristic keyword items should be provided.

4. Text a. Introduction. In this part, the rationale for research and formulation of the scientific problem should be included and supported by a concise review of recent literature. b. Main text. It should contain all important elements of the scientific investigations, such as presentation of experimental setup, mathematical models, results and their discussion. This part may be divided into the following sections: Methods, Results, Discussion. c. Conclusions. The major conclusions can be put forward in a concise style in a separate chapter. A presentation of conclusions from the reported research work accompanied by a short commentary is also acceptable. d. Figures: drawings, diagrams and photographs can be in colour and should be located in appropriate places in the manuscript. Their form should be of a vector or raster type with the minimum resolution of 900 dpi. In addition, all figures, including drawings, graphs and photos should be uploaded in a separate file via Editorial System in one of the following formats: bmp, tiff, jpg or eps. For editorial reasons, graphic elements created with MS Word or Excel will not be accepted. They should be saved as image files in the source program. Screen shots will not be accepted. The basic font size of letters used in figures should be at least 10 pts after adjusting graphs to the final size. e. Tables should be made according to the format shown in the template. f. All figures and tables should be numbered and provided with an appropriate caption and legend, if necessary. They have to be properly referenced to and commented in the text of the manuscript.

5. List of symbols should be accompanied by their units

6. Acknowledgements may be included before the list of literature references

7. Literature citations The method of quoting literature source in the manuscript depends on the number of its authors: • single author – their surname and year of publication should be given, e.g. Marquardt (1996) or (Marquardt, 1996), • two authors – the two surnames separated by the conjunction “and” with the publication year should be given, e.g. Charpentier and McKenna (2004) or (Charpentier and McKenna, 2004), • three and more authors – the surname of the first author followed by the abbreviation “et al.” and year of publication should be given, e.g. Bird et al. (1960) or (Bird et al., 1960).

In the case of citing more sources in one bracket, they should be listed in alphabetical order using semicolon for separation, e.g. (Bird et al., 1960; Charpentier and McKenna, 2004; Marquardt, 1996). Should more citations of the same author(s) and year appear in the manuscript then letters “a, b, c, ...” should be successively applied after the publication year.

Bibliographic data of the quoted literature should be arranged at the end of the manuscript in alphabetical order of surnames of the first author. It is obligatory to indicate the DOI number of those literature items, whose numbers have already been assigned. Journal titles should be specified by typing their right abbreviations or, when in doubts, according to the Science and Engineering Journal Abbreviations.

Suggested Reviewers

Authors are kindly requested to include a list of 4 potential reviewers for their manuscript, with complete contact information. Suggested reviewers may not reside in the same country as the corresponding author and remain subject to the Editors' discretion in appointing manuscripts for review.

Payments

Starting from 2014 a principle of publishing articles against payment is introduced, assuming non-profit making editorial office. According to the principle, authors or institutions will have to cover the expenses amounting to 1500 PLN netto (excl. VAT) per published article. The above amount will be used to supplement the limited financial means received from the Polish Academy of Sciences for the editorial and publishing expenses. The method of payment will be indicated in an invoice sent to the authors or institutions after acceptance of their manuscripts to be published.
