Submissions

Author Guidelines

Submission and Evaluation

When filling out the registration of authors in the journal system and submitting a manuscript, a confirmation email is sent to the corresponding Author. The editorial review process only starts if the manuscript follows the established norms (Submissions and Manuscript preparation (Template)); otherwise, it is returned for adequacy.

Manuscripts that comply with the prescribed standards will be submitted to similarity detection software and analyzed by the Editorial Committee, which will decide whether or not to proceed with the editorial analysis.

Editorial committees decision to accept or reject a submission paper will be based only on the paper’s importance, originality, and clarity, and the study’s relevance to the remit of the journal.

Papers not suitable for the journal scope will be returned to the Authors, even before the technical-scientific analysis. Manuscripts with problems regarding the textual composition structure will be returned and, if corrected, can be resubmitted.

The submitted manuscript will not be retained or copied. Editors will treat all submitted papers as confidential.

Initially approved by the Editorial Committee, the manuscripts will proceed to the next phase where the evaluators will be chosen by this same Committee, among researchers of recognized competence in the specific area of each work and, preferably, linked to different institutions from those where the manuscript under analysis was originated.

Considering that Judgments must be objective, reviewers must not present any bias and no conflict of interest.

The Editorial Committee asks the reviewers, before starting the analysis of a manuscript, to consider the possibility of some situations and/or relationships that may compromise the impartiality of the evaluation process, such as regular collaboration with possible authors in activities of research, advisor-student association, commercial interest in the publication, family relationship. In these cases, the reviewer is asked to immediately return the manuscript, communicating the impossibility of analyzing it.

 

Manuscript Preparation (Template)

The base file for preparing the manuscript is to be accessed at the link below:

Template in English: Download

_{_________________}

Observation 1: Do not include the names of the authors and affiliation in the Word file. Enter the authors' data only in the journal's system.

Observation 2: Authors should write in clear, concise US or UK English. Language and grammar should be consistent with Fowler's English Usage; spelling and meaning of words should conform to Webster's Dictionary or British Dictionary. If English is not your first language, it may be beneficial to seek help from a native English speaker to review your manuscript before submitting it or to have your manuscript professionally edited before submission. 

Observation 3: "Self-Citation and Main Databases" - The BJS accepts a maximum rate of 5% of self-citations and also recommends that 65% of bibliographic references be from articles listed in the ISI Web of Science Knowledge, Scopus, or SciELO databases that are less than 10 years old. We recommend giving preference to citations from international articles.

 

Benefits for Authors

Articles published in the BJS are Open Access, giving a number of advantages for the widest dissemination, visibility, and impact of your research.

Publishing as Open access offers authors a number of benefits, including:

a) Higher and faster visibility: Open Access articles are viewed on a global scale, and contents are available to everyone.
b) Wider impact: Thanks to a permissive license like Creative Commons Attribution 4.0 Internacional (CC BY 4.0), scientists and scholars are endowed to make progress on existing researches, thus facilitating the generation of new data.
c) Increased citation: Studies have shown that Open Access articles are regarded and cited more often than established paywall journals/articles.
d) Perpetual accessibility: Open Access articles are hosted on dedicated servers, being accessible to everyone endlessly.
e) Funding opportunities: an increasing number of funding bodies and agencies requires their grant holders to publish their researches as Open Access articles to be comprehensively available, free and without restrictions on re-use.

 

Affiliation

The primary affiliation for each author should be the institution where the majority of their work was done. If an author has subsequently moved, the current address may additionally be stated. Addresses will not be updated or changed after publication of the article.

 

Permissions

Authors wishing to include figures, tables, or text passages that have already been published elsewhere are required to obtain permission from the copyright owner(s) for both the print and online format and to include evidence that such permission has been granted when submitting their papers. Any material received without such evidence will be assumed to originate from the authors.

 

Deceased or Incapacitated Authors

For cases in which a co-author dies or is incapacitated during the writing, submission, or peer-review process, and the co-authors feel it is appropriate to include the author, co-authors should obtain approval from a (legal) representative which could be a direct relative.

 

Editorial Policy

The Brazilian Journal of Science is publications in continuous flow (with early access for accepted articles) that edits and publishes original technical-scientific works, in English, resulting from scientific research. The main form of contribution is the Article, but it also publishes Scientific Notes and Reviews.

 

Reviewer Suggestions

Authors should provide a list of 4 potential reviewers (full name, e-mail, and affiliation) who are knowledgeable in the subject matter, have no conflict of interest, and are likely to agree to review the manuscript. This will significantly help facilitate timely peer review. Please ensure that 3 of the potential reviewers are from a different country than the authors and are not editors of the journal.

Attention: Editors are not able to review papers. Please also ensure that you include full contact details for each suggested reviewer - the institution, country, and correct, up-to-date email addresses.

 

Volunteer Reviewers

BJS is actively looking for volunteers to review manuscripts. The members of the BJS Reviewer Board and Volunteer Reviewers can actively offer to review manuscripts in one or more of Cerrado Publishing journals.

Note: This evaluation process is voluntary. The volunteer evaluator must have a Master's, Doctorate, or PhD degree, and present a considerable number of publications in journals in the ISI Web of Science Knowledge, Scopus, or SciELO databases.

 

Authorship Issues or Disputes

In the case of an authorship dispute during peer review or after acceptance and publication, the Journal will not be in a position to investigate or adjudicate. Authors will be asked to resolve the dispute themselves. If they are unable the Journal reserves the right to withdraw a manuscript from the editorial process or in case of a published paper raise the issue with the authors’ institution(s) and abide by its guidelines.

 

Generative AI and Figures, Images, and Color Art

We do not permit the use of Generative AI or AI-assisted tools to create or alter images in submitted manuscripts. Our exception is if the use of AI or AI-assisted tools is part of the project or research methods (e.g. in the field of biomedical imaging, cytology, and drone use).
If this is the case, such use must be described in a reproducible manner in the Material and Methods section (subtopic: e.g. 2.1 ), including the name of the model or tool, version and extension numbers, and manufacturer.
The use of generative AI or AI-assisted tools in the production of Graphical Abstracts under human supervision is permitted. If the Graphical Abstract follows this standard, authors must notify the Editor by message during the submission of the study.

 

Graphical Abstract

From volume 3, Issue 1-12 in 2024 will have a Graphical abstract.

A graphic should be included when possible. This must be submitted separately as an electronic file (preferred file types are EPS, PDF, TIFF, Microsoft Word, PowerPoint and CDX etc.). A graphical abstract, not exceeding 30 words along with the illustration, helps to summarize the contents of the manuscript in a concise pictorial form. It is meant as an aid for the rapid viewing of the Brazilian Journal of Science contents and to help capture the readers’ attention.

The graphical abstract may feature a key structure, reaction, equation, etc. that the manuscript elucidates upon. It will be listed along with the manuscript title, author’s names, and affiliations on the contents page, typeset within an area of 5 cm by 17 cm using a regular screen resolution of 96 dpi, but it will not appear in the article's PDF file or print. Graphical Abstracts should be submitted as a separate file (must mention the graphical abstract within the file). It must not be an image already used in the manuscript. Photos of commercial equipment will not be accepted in the Graphic Abstract. We suggest the following software for Graphical Abstract, BioRender, or others.

 

Declaration of Artificial Intelligence (AI) Generation in Scientific Writing

Authors must declare the use of generative AI in scientific writing upon submission of the paper. Some guidelines:

a) Generative AI should only be used in the writing process to improve the readability and language of the manuscript.
b) The technology must be applied with human oversight and control and authors should carefully review and edit the result.
c) AI can produce results that appear authoritative but may be incorrect, incomplete, or biased without human oversight.
d) Authors are ultimately responsible and accountable for the contents of the study.
and attention!
e) Authors must not list or cite AI and AI-assisted technologies as authors or co-authors on the manuscript since authorship implies responsibilities and tasks that can only be attributed to and performed by humans.

Important Note!
The use of generative AI and AI-assisted technologies in scientific writing must be declared by adding a statement at the end of the manuscript when the paper is first submitted. The statement will appear in the published work and should be placed in a new section before the references list.

Title of new section: Declaration of generative AI and AI-assisted technologies in the writing process.

Statement: Download

During the preparation of this study, the author(s) used [Name Tool/ Service] 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 published article.

If Artificial Intelligence AI is used, add this statement (link) during study submission.

 

After Acceptance

Upon acceptance, your article will be exported to Production to undergo typesetting. Shortly after this you will receive two e-mails. One contains a request to confirm your affiliation, choose the publishing model for your article, as well as to arrange rights and payment of any associated publication cost. A second e-mail containing a link to your article’s proofs will be sent once typesetting is completed.

 

Changes to Authorship

Authors are expected to consider carefully the list and order of authors before submitting their manuscript and provide the definitive list of authors at the time of the original submission. Any addition, deletion, or rearrangement of author names in the authorship list should be made only before the manuscript has been accepted and only if approved by the journal Editors.

To request such a change, the Editor-in-Chief must receive the following from the corresponding author: (a) the reason for the change in the author list and (b) written confirmation (e-mail, letter) from all authors that they agree with the addition, removal or rearrangement. In the case of addition or removal of authors, this includes confirmation from the author being added or removed.

Only in exceptional circumstances will the Editor-in-Chief and Associate Editor consider the addition, deletion or rearrangement of authors after the manuscript has been accepted. While the Editorin-Chief and Associate Editor consider the request, publication of the manuscript will be suspended. If the manuscript has already been published in an online issue, any requests approved by the Editors will result in a corrigendum.

 

Main Text

Manuscript content should adhere to the criteria for the manuscript type selected. Manuscripts must be written in English by competent, grammatically correct, and scientific persons; the absence of these qualities inhibits and undermines the effectiveness of the peer review process, causing substantial delays in this step.

An informal tone and overuse of first-person pronouns, especially used as adjectives or possessives (e.g., “my”, “mine”, “our”, “ours”) and second-person pronouns (e.g., “you”, “your”) should be avoided!

 

Acronyms/Abbreviations/Initialisms

Should be defined the first time they appear in each of three sections: the abstract; the main text; and the first Figure or Table. When defined for the first time, the acronym/abbreviation/initialism should be added in parentheses after the written-out form.

Spelling - These should be as in the Concise Oxford Dictionary of Current English.

 

Common and Scientific Names

Attention: Both common and scientific names vary in time and space. To maximize the ability of readers to identify study organisms across the world and over time but allow authors maximum flexibility in choosing their preferred authorities:

(1) If taxonomy has changed within the last 10 years, the former name of the organism may be presented at the first use of the name [example: Eupatorium polystachyum DC. (= Raulinoreitzia crenulata (Spreng.) R.M. King & H. Rob.)]. If your preferred taxonomic hypothesis differs from that of other authors, make sure to include the more commonly used name.

(2) Species occurring out of Brazil: standard English and Spanish names should be provided at first occurrence. Standard names of all animals must be capitalized and used in the plural (e.g., Pepper Frogs). For North American species (example) use the pattern available in the North American Species Name Database (SSAR). For species in other parts of the world, common names are optional-follow an appropriate regional reference if available (e.g., Rãs Pimenta or Rã Pimenta in Portuguese (Brazil) and Chandala or Chandalas in Portuguese (Angola)).

 

Numbers

Always spell out a number used at the beginning of a sentence (Example: Thirty species…). Spell out all whole numbers less than 10, except as noted below.

- Use Arabic numerals:

• For numbers of 10 or greater
• When the number is followed by a unit of measurement. Example: “7 mm”
• When the number is a designator. Example: “Experiment 5”
• When a range of values is given. Example: “3–6 scutes”
• When numbers of 10 or more are compared to numbers less than 10 within a sentence. Example: “The 5 fruits, 7 reptiles, and 15 snakes that we collected…”
• Decimal values; if decimal value is < 1, use zero before decimal. Example: “0.4 or 0.7”

- Use commas in numbers with four or more digits. Example: “155” and “1,321”.

- Avoid excessive significant digits. Example: when measuring length with a ruler where the smallest measurement unit is 1 mm, report mean values as “10.55 mm” and standard deviation as “0.66 mm”.

- Numbers or letters in a list should be fully enclosed in parentheses. Example: Experiments (5), (6), and (3) failed; (2) did not.

- Geographic coordinates can be in any standard format, such as decimal degrees or UTM.

 

Nomenclature and SI Units (International System of Units)

Should be used. Imperial, US customary and other units should be converted to SI Units (NIST) (https://www.nist.gov/pml/owm/metric-si/si-units) whenever possible. Abbreviations used in tables and figures should be explained in the captions. In general, the recommendations of the International Union of Pure and Applied Chemistry (IUPAC) should be followed (http://www.iupac.org).

Exemples:

- Linear measurement: Millimeters = mm, Centimeters = cm, Meters = m, Kilometers = km

- Area: hectare = ha

- Volume: Milliliters = mL, Liters = L

- Mass: Grams = g, Kilograms = kg

- Use the negative index (m^-1, L^-1, h^-1) except in cases such as (per plant).

- Time: Seconds = s, Minutes = min, Hours = h, Days = d, Week = wk, Month = mo, Years = yr. For time of day, use a 24-hour clock. Example: 1500 h.

- Date: use Month Day, Year with no commas, spelling out the name of the month. Example: “June 10, 2023”.

- Temperature: Celsius, with space after number and with a degree symbol before the abbreviation for temperature scale. Example: “25 °C or 100 °C”.

- Concentration: mol L ^-1, 10³ (T/K) ^-1, g 100^-1, g kg^-1, g 100 g DM^-1.

- Symbols: representing physical quantities should be given in italics.  J (Hz), δ (ppm), m/z.

- Labeled atoms in ORTEP: (or any other) diagrams should have atom numbers in parenthesis, e.g., Fe(1), C(44).

- Amount of substance: mole = mol, mol L^-1, mol dm^-3.

 

Mathematical Formula

BJS recommends carefully following the rules for Mathematical formulas:

Please submit math equations as editable text and not as images. Present simple formulae in line with normal text where possible and use the solidus (/) instead of a horizontal line for small fractional terms, e.g., X/Y our X/Y/Z. In principle, variables are to be presented in italics. Number consecutively any equations that have to be displayed separately from the text.

 

Statistical Abbreviations

- Please do not italicize Greek letters. Examples: “α”, “χ³”.

- Italicize all other statistical symbols. Examples: “r”,’ r²”, “F”, “t” (as in t-test or Tukey’s test).

- Sample size: lower case and italicized. Example: “n = 10”.

- Mean or average: use “X” (capitalized and italicized) or spell out the word “mean” -SD = standard deviation, SE = standard error, CI = confidence interval; often indicated as “± SD”, “± SE”, “± 3 SE”, 100% CI = 1.40 - 6.70, etc.

- All statistical tests should include the test statistic, n or df, and P-value denoted as follows:

- For most test statistics, degrees of freedom should appear as subscripts (e.g., F₃,₅, t₄). Otherwise, they can be reported as “df” (e.g., “df = 8“).

- Probability: capitalize and italicize. Example: “P = 0.005.” When not significant, provide the value, rather than using “NS” or “P > 0.05.” Example: “P = 0.20”.

 

Mathematical Signs and Symbols

- Separate mathematical operators by spaces on both sides. Examples: “α = 0.05”; “P < 0.015”; "p < 0.05" and “12 ± 0.03”.

- Separate a number from a symbol to indicate a mathematical operation. Example: “2 + 2 = 4”.

- Do not use a space between the “-“ and the “+” when indicating positive or negative values.

Examples: “-5 °C”, “+10 mm”.

- The symbols for “similar to” and “nearly equal to” are not followed by space. Examples: “~21”, “≈35”.

- Use “log” for log base x (e.g. log base 10 would be log10) and “ln” for natural log.

- In mathematical functions, fences typically go in this order: { [ ( ) ] }.

 

Chemistry Formula

Figures, Schemes, Tables, and Structures should be drawn to fit single or double-column widths. They should look proportional in case they are reduced. Structures should be numbered with bold Arabic numerals, (e.g., 1, 2,...).

All chemical structures included in the manuscript should be drawn using the same letter type (Times New Roman), size of cyclic groups, size and thickness of chemical bonds, and, most importantly, authors should use the same standard throughout the work, including all Figures, Schemes, Tables, and Structures.

The following organic group abbreviations may be used: Me, Et, ⁿPr, ⁿBu, Ph, CO ²R, CO 2H, and ⁱPrOH. One variable univalent substituent is indicated by R. When more than one independent variable general substituent is present, R¹, R², R³, etc. should be used. A variable metal may be indicated by M and variable ligands by L¹, L², or L1, L2, L3. Chemical formulas may also be given: H₂O, C-C, C=O, etc.

 

Specific Chemistry

1) Chemical Structures and Reaction Schemes: Chemical structures and reaction schemes should be drawn using an appropriate software package designed for this purpose. As a guideline, these should be drawn to a scale such that all the details and text are clearly legible when placed in the manuscript (i.e., text should be no smaller than 8–10 pt.). To facilitate editing we recommend the use of any of the software packages widely available for this purpose: ACD/ChemSketch^®, ChemWindow^®, CS ChemDraw^®, MDL^®Isis/Draw, and others. Free versions of some of these products are available for personal or academic use from the respective publishers.

2) Correct Identification and Characterization of Chemical Compounds: The correct identification of the chemical compounds is a key part of scientific information; thus, the BJS will not accept papers lacking chemical characterization except in (preliminary analysis/phytochemical prospecting). For this reason, if the manuscript reports on the synthesis and/or extraction and/or characterization of chemical compounds, the authors are strongly encouraged to fill out and submit the Chemical Characterization Checklist, marking the performed analyses. The Checklist will be available to Editors and Reviewers to support them in assessing the completeness and robustness of the compound’s characterization. The inclusion of original spectra in the Supplementary Material is highly recommended.

3) Organic Compounds: Reports on previously undescribed organic compounds should include, as supplementary data, 1H, 13C, 14C and/or other key heteronuclear or 2D NMR spectra, together with High-Resolution Mass Spectrometry (HRMS) or elemental analysis. The identification of known compounds in extracts must be supported with chromatographic and/or spectroscopic data (e.g., LC/GC retention times and/or UV, mass spectra), as well as comparison with data of authentic samples or previously published values. Attention: When reporting and comparing biological or catalyst activity, the claimed purity must be fully supported by appropriate analytical techniques, e.g., NMR spectra, HPLC data, etc.

4) Inorganic and Organometallic Compounds: Reports on previously undescribed inorganic/organometallic compounds must provide adequate data to establish their identity and degree of purity. Whenever possible, the supplementary material should include an elemental analysis, X-ray single crystal or powder diffraction. However, please note that an X-ray single crystal structure may not be sufficient for the characterization of new compounds and the X-ray powder diffractogram, including the simulated one, should be provided. Attention: Additional characterization for particular samples, such as NMR spectroscopy, mass spectrometry (MS), infrared spectroscopy (IS), electronic spectroscopy (ES), etc., should also be included, if available.

 

References to Drugs

BJS recommends drug use according to the rules:

The generic name of a drug should be used as a general rule; however, the full name or the commercial name of the drug, as well as the name and location of the supplier, may be given in addition if appropriate.

 

Bacterial, Fungi, Protozoa, Algae and Virus Nomenclature (Systematic)

(1) In general for bacterial

Microbes should be referred to by their scientific names according to the binomial system used in the latest edition of Bergey's Manual of Systematic Bacteriology (The Williams and Wilkins Co.) (https://www.springer.com/series/4157). When first mentioned, the name should be in full and written in italics. Thereafter, the genus should be abbreviated to its initial letter, e.g. Staphylococcus aureus > S. aureus NOT Staph. Aureus. If the abbreviation is likely to cause confusion or render the intended meaning(s) unclear the names of organisms should be given in full.

Or when there is a serotype: Salmonella enterica subsp. enterica serovar Typhimurium.

For studies with fungi, protozoa, algae and viruses, follow the guidelines of the American Society of Microbiology, Manual of Clinical Micribiology.

(2) In general for Fungi:

In the text where it is cited for the first time, describe the full name and its repetition, using an abbreviation. Example (Synchytricum endobioticum and its repeat S. endobioticum or Candida albicans and its repeat C. albicans. Recommends using Species Fungorum or Bergey's Manual of Systematic Bacteriology (The Williams and Wilkins Co.).

(3) In general for Protozoa:

For studies involving protozoa, BJS recommends using The World of Protozoa, Rotifera, Nematoda and Oligochaeta.

(4) In general for Algae:

For studies involving algae, BJS recommends using Algae Identification and Nomeclature (Lab Guide) or Manual on Harmful Marine Microalgae.

(5) In general for Virus:

For studies involving viruses, BJS recommends using Virus Taxonomy (National Library of Medicine) (NIH), or Encyclopedia of Virology - Fourth Editon, v. 1, p. 28-37, or Center for Management and Strategic Studies (CGEE).

 

Footnotes

Footnotes should be used sparingly. Number them consecutively throughout the article. Many word processors can build footnotes into the text, and this feature may be used. Otherwise, please indicate the position of footnotes in the text and list the footnotes themselves separately at the end of the article. Attention: It is recommended to use a hyperlink in the numbering. Do not include footnotes in the Reference list.

 

Author Affiliation
All authors should list their current affiliation and the affiliation where most research was carried out for the preparation of their manuscript. We recommend adding as primary the affiliation where most of the research was conducted or supported, but please check with your institution for any contractual agreement requirements.
After the publication of an article, updates or corrections to the author’s address or affiliation may not be permitted.

 

Independent Researcher
If one or all the authors are not currently affiliated with a university, institution or company, or have not been during the development of the manuscript, they should list themselves as an “Independent Researcher”.

 

Authors’ Contributions

The author and his/her collaborators must indicate the contributions they made in the research process and obtaining results following the CRediT taxonomy in a specific topic listed in the study Template. Defend that your institution and any publication you submit recognize and adopt the taxonomy.

Role of the Funding Source

Authors are requested to identify who provided financial support for the conduct of the research and/or preparation of the article and to briefly describe the role of the sponsor(s), if any, in study design; in the collection, analysis and interpretation of data; in the writing of the report; and in the decision to submit the article for publication. If the funding source(s) had no such involvement, it is recommended to state this.

 

Accession Numbers of RNA, DNA, Protein Sequences, and Enzymology Data

Accession numbers of RNA, DNA, and Protein sequences used in the manuscript should be provided in the Materials and Methods section (Template article). Also see the section on:

(1) New nucleic acid sequences must be deposited into an acceptable repository such as GenBank, DDBJ, and EMBL. Important Note: Sequences should be submitted to only one database.

(2) New high throughput sequencing (HTS) datasets (RNA-seq, ChIP-Seq, degradome analysis, among others) must be deposited either in the GEO Database or in the NCBI’s Sequence Read Archive (SRA).

(3) New microarray data must be deposited either in the Gene Expression Omnibus (GEO) or the ArrayExpress databases (BioStudies.).

(4) New protein sequences obtained by protein sequencing must be submitted to UniProt (SPIN). Annotated protein structure and its reference sequence must be submitted to (RCSB) of Protein Data Bank (PDB).

End (5) For research with enzymes BJS recommends following the guidelines of the Beilsten Institut Guide. The Standards for Reporting Enzymology Data (STRENDA Guidelines) aim to support authors to comprehensively report kinetic and equilibrium data from their investigations of enzyme activities.

 

Deposition of Proteomics Data

Reporting guidelines for proteomics. Methods used to generate the proteomics data should be described in detail and the BJS recommends that the author adhere to the Minimum Information About a Proteomics Experiment (MIAPE).

 All generated Mass Spectrometry (MS) raw data must be deposited in the appropriate public database such as ProteomeXchange – Center for Computational Mass Spectrometry (CCMS), PRoteomics IDEentifications Database (PRIDE) or Japan Proteome Standard Repository/Database (jPOST). Special note: include the information in only one database!

At the time of submission, please include all relevant information in the materials and methods section, such as the repository where the data was submitted and the link, data set identifier, username, and password needed to access the data.

 

Deposition of Crystallographic Data

When submitting the article with crystallographic data included, the author(s) must deposit, in the relevant Data Center, the data corresponding to each structure to be reported. Data for organometallic, inorganic, organic, and coordination (Werner-type) compounds should be sent to the joint (CCDC/FIZ Karlsruhe) online deposition service (https://www.ccdc.cam.ac.uk/Community/depositastructure/), in CIF format. Cambridge Crystallographic Data Centre (CCDC) (https://www.ccdc.cam.ac.uk/). FIZ Karlsruhe Leibniz-Institut Für Informationsinfrastruktur (https://www.fiz-karlsruhe.de/).

 

Color Art

Color art is free of charge for online publication in the Journal. Attention: If the printed version is displayed in black and white, make sure the key information is still visible. Many colors are not distinguishable from one another when converted to (black and white).
Important note: A simple way to check this is to make a xerographic copy to see if the necessary distinctions between the different colors are still apparent. If the figures will be printed in black and white, do not refer to color in the captions. Color illustrations should be submitted as RGB (8 bits per channel).

 

CheckCIF

During submission of a manuscript to the Brazilian Journal of Science, authors should provide CCDC/FIZ reference numbers as Supplementary Information (separate file). Any revised CIF generated during the editorial process should be deposited directly with the CCDC before the revised manuscript is submitted to the BJS.

During submission, authors are required to provide a checkCIF report for their crystal data together with the manuscript files. This report can be obtained via the free (CheckCIF service) provided by the International Union of Crystallography (IUCr). Any occurrence that produces ‘level A’ and ‘level B’ alerts in the checkCIF should be dealt with in the manuscript or well justified before acceptance of the manuscript can be considered.

 

NMR, IR, and Mass Spectra Data

Whenever a compound is synthesized or identified (new or already known), it is imperative to send all spectral data (data and spectra) as Supplementary Information (SI) along with your submission.

Attention: Do not forget to add captions to each one of them, identifying each spectrum (e.g., Figure S1. 1H NMR Spectrum of...; Figure S2. IR Spectrum of...; Figure S3. 13C{1H}Spectrum of...; Table S1. Data for…). If the spectra will be digitalized (scanned), choose options: black and white, without background, and 300 dpi at least.

 

Research Involving Cell Lines

Attention: The material and Methods section for submissions reporting on research with cell lines should state the origin of any cell lines. For established cell lines the provenance should be stated and references must also be given to either a published paper or to a commercial source.

If previously unpublished de novo cell lines were used, including those gifted from another laboratory, details of institutional review board or ethics committee approval must be given, and confirmation of written informed consent must be provided if the line is of human and animal origin.

An example of Ethical Statements:

The HCT116 cell line human was obtained from XXXX. The MLH1+ cell line was provided by XXXXX, Ltd. The DLD-1 cell line was obtained from a PhD. XXXX. The DRGFP and SAGFP reporter plasmids were obtained from PhD. XXX.

 

Borders and Territories

Potential disputes over borders and territories may have particular relevance for authors in describing their research or in an author or editor correspondence address and should be respected.

Content decisions are an editorial matter and where there is a potential or perceived dispute or complaint, the editorial team will attempt to find a resolution that satisfies the parties involved.

Attention: The BJS stays neutral about jurisdictional claims in published maps and institutional affiliations.

 

Supplementary Material

Supplementary material such as applications, images, and sound clips, can be published with your article to enhance it. Submitted supplementary items are published exactly as they are received (Excel or PowerPoint files will appear as such online). Please submit your material together with the article and supply a concise, descriptive caption for each supplementary file. If you wish to make changes to supplementary material during any stage of the process, please make sure to provide an updated file. Do not annotate any corrections on a previous version. Please switch off the 'Track Changes' option in Microsoft Office files as these will appear in the published version.

Declaration of Generative AI in Scientific Writing

Brazilian Journal of Science on the use of artificial intelligence (AI) in article texts.

The below guidance only refers to the writing process, and not to the use of AI tools to analyse and draw insights from data as part of the research process.

Where authors use generative AI and AI-assisted technologies in the writing process, authors should only use these technologies to improve readability and language. BJS allows authors to use AI in their texts, however, with caution!

Where authors use generative 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, and 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 (Material and Methods). A statement will appear in the published work ("subtopic" in Material and Methods). Please note that authors are ultimately responsible and accountable for the contents of the study.
