Notes for Authors

1. Scientific scope

PB Publishing is a fully open-access peer-reviewed publisher from the Petrobras Brazil. The journals publishes high-profile articles on all aspects of the energy sciences and technologies. Our aim is to make our journals the natural home for high-quality energy science results. The energy researchers chemists, geologist, physicists and material scientists are actively encouraged to report their studies. The articles can be technology report, theoretical and practical research.

PB Publishing covers five broad areas: 

  • petroleum and gas science and engineering;

  • energy technology;

  • environmental science and technology;

  • geosciences and technology; and

  • social sciences and policy.

Articles in PB Publishings are open-access, i.e. free of charge to all readers. The costs for peer review, journal production, and online hosting and archiving are met by publisher supporting from Petrobras Brazil so far. 

2. Categories of contributions

Contributions should conform to the general editorial style of PB publishing Journals. Typical articles may be viewed by going to Articles should be written with a wide scientific audience in mind.

2.1. Research Papers

Full-length Research Papers describe important original research work. They should not normally exceed seven journal pages (about 7000 words). Abstracts should provide the context of the study, the main findings and the broad significance of the results. These should be typically 250 words but must not exceed 300 words.

2.2. Research Letters

Research Letters report significant findings of immediate interest. They should be typically 4000 words including a fully referenced abstract not exceeding 300 words. The letters can be accompanied by three figures and one table.

2.3. Reviews

Reviews aim to capture the current trend of a field and are expected to be relatively short. Typically they should contain about 6000 words and a maximum of 70 references, with half of those having been published in the last three years. Inclusion of new results, as well as a historical perspective, is appropriate.

2.4. Scientific Commentaries

Scientific Commentaries discuss articles of particular importance for the readership of the journal. Suggestions for suitable topics and of potential author(s) are welcomed by the Main Editors.

3. Submission and handling of articles

3.1. Submission

All submissions should be accompanied by a covering letter that explains the significance of the work reported, and recommended possible 3-5 reviewers. 

Articles should be submitted at Full instructions for submitting an article and details of the files required are given at Authors are encouraged to use the templates available from The contact author must provide an e-mail address for editorial communications. 

3.2. File format

The source files required for an article are: a single file in Word, OpenOffice or LaTeX format of the text, tables and figures of the article; a high-resolution graphics file (minimum 300 d.p.i.) in TIFF, PostScript, encapsulated PostScript, JPEG or PNG format for each figure and scheme; and files of any supporting information. These should be uploaded as described in the online submission instructions.

3.3. Handling of articles

All contributions will be seen by the Main Editors before peer review. The Main Editors decide whether articles are sent for peer review, or are rejected without further review.

Articles considered suitable for peer review will be assigned to a Co-editor. The Co-editor is responsible for choosing referees and for accepting or rejecting the article. This responsibility includes decisions on the final form of the article and interpretation of these Notes when necessary. Articles will normally be seen by at least two referees before they can be accepted for publication. Further information on the peer-review process can be found at

Changes to a manuscript requested by a Main Editor, Co-editor or the editorial staff should be received within two months of transmittal to the author, otherwise the submission will be considered as withdrawn. If a manuscript is not acceptable after two revisions it will not be considered further. Any subsequent communication of the material will be treated as a new submission in the editorial process. An article that has been rejected must not be resubmitted to any PBPUBLISHING Journal unless the reasons given for the rejection have been fully addressed in the revised version.

After initial submission, any revised or new files should be uploaded only in response to a specific request from an editor.

On acceptance, the author will also be asked to pay the open-access fee or provide a waiver. For accepted articles, it is the responsibility of the Managing Editor to prepare the article for publication. This may involve correspondence with the authors and/or the responsible editor in order to resolve ambiguities or to obtain satisfactory figures or tables. The date of acceptance that will appear on the published article is the date on which the Managing Editor receives the last item required. Contact details for the Managing Editor of PBpublishing can be found at

On rare occasions, an editor may consider that an article is better suited to another BP Publishing Journal. Any change to the journal of publication will only be made after full discussion with the contact author.

Articles will be checked for plagiarism using the CrossCheck service.

3.4. Author's warranty and ethical considerations

The submission of an article is taken as an implicit guarantee that the work is original, that it is the author(s) own work, that all authors are aware of and concur with the submission, that all workers involved in the study are listed as authors or given proper credit in the acknowledgements, that the manuscript has not already been published (in any language or medium), and that it is not being considered and will not be offered elsewhere while under consideration for PB Publishing. The inclusion of material in an informal publication, e.g. a preprint server or a newsletter, does not preclude publication in PB Publishing.

The co-authors of an article should be all those persons who have made significant scientific contributions to the work reported, including the ideas and their execution, and who share responsibility and accountability for the results. Other contributions should be indicated in the acknowledgements. Changes to the list of authors will normally require the agreement of the editor and all authors.

The PB Publishing is a member of COPE (Committee on Publication Ethics) and endorses its recommendations, including the Code of Conduct for Editors, which are available at Important considerations related to publication have been given in the ethical guidelines published in Acc. Chem. Res. (2002), 35, 74–76 and Graf et al. [Int. J. Clin. Pract. (2007), 61 (Suppl. 152), 1–26]. Authors are expected to comply with these guidelines. 

3.5. Copyright

Authors will not be asked to transfer copyright to the PB Publishing, but will instead be asked to agree during article submission to an open-access licence. This licence is identical to the Creative Commons Attribution (CC-BY) Licence.

4. Article preparation

4.1. General information

Articles should be clearly and simply written so that they are accessible to as broad a readership as possible. Before preparing articles, authors should consult a current issue of the journal to make themselves familiar with the general format, such as the use of headings, layout of tables and citation of references.

The title of the article should be written to appeal to a wide audience and should include key phrases in the subject area. The use of acronyms or abbreviations should be avoided.

All contributions must be accompanied by an English language Abstract. The Abstract should state as specifically and as quantitatively as possible the principal results obtained. Authors should also supply at least five keywords. These may include synonyms and specific phrases related to the subject of the article.

The Abstract should be suitable for reproduction by abstracting services without change in wording. It should not repeat information given in the title. It should make no reference to tables, diagrams, atom numbers or formulae contained in the article. It should not contain footnotes and should not include the use of `we' or `I'.

4.2. Diagrams and photographs ('figures')

Figures should be prepared using one of the file formats listed in §3.2[link] and should be included in the article at the point that they are first mentioned.

The choice of figures should be optimized to produce the shortest article consistent with clarity. Duplicate presentation of the same information in both tables and figures is to be avoided, as is redundancy with the text. Supplementary figures may be deposited (see §5[link]).

4.2.1. Quality

Electronic files in the formats listed in §3.2[link] are essential for high-quality reproduction. The resolution of bitmap graphics should be a minimum of 600 d.p.i.

4.2.2. Size

Diagrams should be as small as possible consistent with legibility. They will normally be sized so that the greatest width including lettering is less than the width of a column in the journal (8.8 cm).

4.2.3. Lettering and symbols

Fine-scale details and lettering must be large enough to be clearly legible (ideally 1.5–3 mm in height) after the whole diagram has been reduced to one column width.

Lettering should be kept to a minimum; grids and shadings should be avoided where they are not required for clarity. Descriptive matter should be placed in the caption.

4.2.4. Numbering

Diagrams should be numbered in a single series in the order in which they are referred to in the text.

4.3. Tables

Authors submitting in Word should use the Word table editor to prepare tables.

4.3.1. Use of tables

Extensive numerical information is generally most economically presented in tables. Text and diagrams should not be redundant with the tables.

4.3.2. Design, numbering and size

Tables should be numbered in a single series of arabic numerals in the order in which they are referred to in the text. They should be provided with a caption.

Tables should be carefully designed to occupy a minimum of space consistent with clarity.

4.4. Mathematics and letter symbols

Authors submitting in Word should use the Word equation editor to prepare displayed mathematical equations.

The use of the stop (period) to denote multiplication should be avoided except in scalar products. Generally, no sign is required but, when one is, a multiplication sign (×) should be used.

Scalar variables and non-standard functions should appear in italic type.

Vectors should be in bold type and tensors should be in bold-italic type.

Greek letters should not be spelled out.

Care should be taken not to cause confusion by using the same letter symbol in two different meanings.

Gothic, script or other unusual lettering should be avoided. Another typeface may be substituted if that used by the author is not readily available.

All displayed equations, including those in published Appendices, should be numbered in a single series.

4.5. Funding information

This section aims to help authors comply with the reporting requirements of funders, and includes information on funders and grant/award numbers. Funding information should be included in the Acknowledgements section.

4.6. References

References to published work must be indicated by giving the authors' names followed immediately by the year of publication, e.g. Neder & Schulz (1998) or (Neder & Schulz, 1998). Where there are three or more authors, the reference in the text should be indicated in the form Smith et al. (1998) or (Smith et al., 1998) etc.

In the reference list, entries should be arranged alphabetically and conform with the following style:
