Journal of the Brazilian Chemical Society
Brief Background
|
The Journal of the Brazilian Chemical Society (JBCS) is published by PubliSBQ (http://publi.sbq.org.br/) managed by the Sociedade Brasileira de Química (SBQ) since 1990. The JBCS serves its readers as a forum for information related to the advancement of Chemistry. The Journal is devoted to the publication of research papers in all fields of Chemistry, except education, philosophy and history of Chemistry. The online Journal is open access through the website: http://jbcs.sbq.org.br/.
The Journal of the Brazilian Chemical Society embraces all aspects of chemistry except education, philosophy and history of chemistry. It is a medium for reporting selected original and significant contributions to new chemical knowledge. Publication of the Journal of the Brazilian Chemical Society is in charge of the Editors, and its policy and planning are the responsibility of the Editorial Advisory Board . Manuscripts submitted to the journal are analyzed by peer-reviewers. Its abbreviated title is J. Braz. Chem. Soc., which should be used in bibliographies, footnotes and bibliographical references and strips. |
Open Science Compliance
|
The Journal of the Brazilian Chemical Society (JBCS) is a fully open access journal. All articles published by the JBCS are made freely and permanently accessible online immediately upon publication, without any subscription charges or registration barriers. Additionally, the JBCS embraces open science principles, including the acceptance of preprints. Authors are encouraged to publish shared data on their preferred platforms, further promoting transparency and collaboration within the scientific community. |
Ethics in Publication
|
JBCS expects that, on submitting their papers, authors follow the ethical rules described below. Otherwise, they will be subjected to sanction according to COPE (Committee on Publication Ethics) recommendations. COPE has been the forum for the JBCS editors in the guidance or recommendations concerning ethics of scholarly publishing.
1 - Information and co-authorship permission The submitting author is responsible for including in the author list the names of every researcher actually responsible for the work. It is his/her duty to inform his/her collaborators of the manuscript content and obtain their permission for submission and publication. 2 - Privileged Information It is the authors’ responsibility to carefully search through the several searching sites (SCI-ISI, Scopus, Google, and so on) for all the scientific work relevant to their reasoning, whether they agree or not with the results and hypotheses presented. Data taken from the work of researchers, other than the ones who are authors of the manuscript being submitted to JBCS, must be properly cited and credited. Such identification must be as detailed as possible. Privileged information, such as personal communications or discussions with a non-author, can only be cited with the explicit permission of the involved researcher. 3 - Fragmentation Work fragmentation takes too much journal space and makes literature research more difficult and time consuming. A scientist who does extensive work in a system or group of similar systems should organize his/her publication so as to present a solidly based study, as complete as possible, even if it covers only one aspect of such system. 4 - Exclusivity Simultaneous submission of the same manuscript to more than one journal places unnecessary extra load on the peer reviewing system, and expectations on the journal that may be deceived if an accepted manuscript is withdrawn, representing an ethical deviation which is not accepted in the SBQ Journals. 5 - Duplication/Plagiarism Plagiarism, defined as “the appropriation of someone else’s ideas, processes, results or words, without the proper credit” is not accepted in SBQ’s scientific journals. We consider plagiarism the word-for-word (or close to) copy of any other author’s texts or sentences. The self-plagiarism, that is, the replication of texts or data from previous works of the authors themselves, with or without the proper citation, is equally unacceptable. Reasonable repetition of some ideas and the re-ordering of one or two sentences by the authors themselves are acceptable. Word-for-word replication of data or sentences must come between quotation marks and with the due credit, in case it is essential for the discussion or contextualization of a specific set of data or hypotheses. It is equally unacceptable the suggestion of newness when the methodology or results have already been published, either by the author him/herself or by any other author. Thus, the JBCS has taken important measures against plagiarism and has licensed iThenticate, plagiarism-checking software to ensure the originality of the submitted manuscripts. |
Focus and Scope
|
To publish research papers in all fields of chemistry, except education, philosophy and history of chemistry. |
Digital Preservation
|
The JBCS editorial office acknowledges the importance of digital preservation to ensure the integrity and accessibility of digital resources over time. To achieve this goal, we have established the following guidelines: The JBCS editorial board is responsible for the implementation and execution of digital preservation activities, and commits to maintaining regular records of the organization's digital resources to identify and document data types, file formats, and storage locations. Digital resources are stored in secure environments and protected against threats such as data loss, corruption, and unauthorized access. The JBCS editorial office is responsible for facilitating the migration of obsolete file formats to more updated formats, ensuring the continuous accessibility of digital resources. Detailed metadata will be maintained for each digital resource, including information about its origin, authenticity, and usage context. Regular backups of digital resources are performed to ensure quick recovery in the event of system failure or data loss. The digital preservation policy will be reviewed and updated regularly to ensure its ongoing effectiveness and compliance with best practices. |

Article Evaluation Process – Peer review evaluation
|
The Journal of the Brazilian Chemical Society employs a single-blind peer review process, where experts in the field evaluate submitted manuscripts. In this process, the reviewers know the identities of the authors, but the authors do not know the identities of the reviewers, ensuring the quality and validity of published research while maintaining high standards of academic integrity and credibility. The peer review process is fundamental for upholding the scientific rigor and trustworthiness of the content. Manuscripts submitted to JBCS undergo initial evaluation by the editorial team to ensure compliance with the criteria set forth in the Ethics Policy. Those found inconsistent in this first stage are returned to the authors. Approved documents are then forwarded to a Chief Editor in the respective field, who subsequently assigns them to an Associate Editor (AE). The AE, besides verifying the manuscript's alignment with the journal's scope, evaluates its scientific merit within the manuscript's thematic area and, if applicable, submits it to at least two ad hoc reviewers. Based on the reviewers' reports and their own assessment, the AE recommends acceptance, minor revisions, major revisions, or rejection of the manuscript. Manuscripts requiring major or minor revisions, or those rejected with the option of resubmission, are returned to the authors for them to address the reviewers' feedback. The revised version undergoes further evaluation by the same AE to determine if additional peer review is necessary. Once approved for publication, the manuscripts proceed to the editing process. |
Data Sharing
|
The Journal of the Brazilian Chemical Society actively promotes a culture of open science by advocating for the sharing, citation, and referencing of comprehensive data, program codes, and other essential content linked to article texts. This initiative serves the purpose of facilitating rigorous research assessment, fostering replicability in scientific investigations, and contributing to the preservation and reuse of valuable content. Authors are encouraged to publish shared data on their preferred platforms. In alignment with standard scholarly practices, citations play an important role in enhancing accessibility to research content. Just as articles, books, and online publications are cited, the same consideration should be given to data, ensuring appropriate in-text citation and inclusion in the bibliography. This approach reinforces transparency, credibility, and the scholarly impact of research outputs. |
Article-Processing Charges (APC)
|
Authors are required to pay an article-processing charge (APC) to help cover the publication costs for their articles. The APC will be applicable only after manuscript acceptance by Editors. Note that the manuscript evaluation by Peer Review is performed as usual. |
APC Values
|
Discounts are offered to all corresponding authors that are active members of the Sociedade Brasileira de Química (SBQ) for at least 2 successive years. Additional discounts are offered whenever 2 or 3 or more papers from the corresponding authors are accepted for publication in a given year in any of the four journals published by SBQ, in whatever order (JBCS, Química Nova, Revista Virtual de Química and Química Nova na Escola). The APC values for all accepted articles are as indicated below.
* Applicable to the four journals published by SBQ (see above), in whatever order. For example, for SBQ members for ≥2 years from overseas institutions, if three papers of theirs are accepted in a given year, the 1st one by JBCS, the 2nd one by Química Nova and the 3rd one by JBCS, the APC for the 1st paper is US$396, whereas the APC for the 3rd paper is only US$247.50.
** Payments from overseas corresponding authors are processed through PayPal. |
Ethics and Misconduct Policy, Errata and Retraction

Policy on Conflict of Interest
|
Conflicts of interest can be personal, commercial, political, academic, or financial. They may occur when authors, reviewers, or editors have interests that could influence the creation or evaluation of manuscripts. Conflict of Interest: Authors must disclose any potential conflicts of interest that may influence their research or manuscript. Reviewers and editors must also declare any conflicts of interest and recuse themselves from handling manuscripts where a conflict exists. Conflict of Interest Resolution: any conflicts of interest related to ethical issues, correction, or retraction will be resolved in accordance with COPE guidelines. |
Adoption of Similarity Checking Software
|
The JBCS has taken important measures against plagiarism and has licensed iThenticate, plagiarism-checking software to ensure the originality of the submitted manuscripts. |
Sex and Gender Equity
|

Template for Supplementary Information
A. Manuscript to be Evaluated for the First Time
The JBCS submission offers only online submission. The submissions are made using the ScholarOne. JBCS system by clicking the link “Submission online (ScholarOne)” at our website (http://mc04.manuscriptcentral.com/jbchs-scielo).
(i) Main manuscript: as full.doc, not as full.pdf and (ii) Figures/Schemes (just the ones from the main document), including GA image: as jpg, tiff, opj, xls, etc (not as individual doc files or grouped in a doc file). Figures built using Excel/Origin programs provide pictures higher quality in the final work (proof), so upload preferentially original xls/opj files.
B. Manuscript already Evaluated (Resubmission: Reject & Resubmission) In cases that the manuscript has already received a decision from JBCS Editor like Reject & Resubmission some specific requirements are necessary: (1) Main document: the modifications need to be highlighted with a different color guiding Editor/Reviewers with changes made in relation to the original version (do not use the track changes mode in MS Word). (2) A comprehensive Response Letter should be prepared submitted along with the cover letter. In this Response Letter, provide a detailed analysis of every comment, including the modifications made, while addressing it to the Referee(s) and the Editor (if applicable). Craft a clear narrative that elucidates the specific alterations and additions, including any new experiments incorporated into the revised manuscript. (3) All the files that were modified should be uploaded in the system. For Reject&Resubmission decision, Authors may access the previous ID (one that received the decision) in the Author Center at the JBCS-ScholarOne submission site (http://mc04.manuscriptcentral.com/jbchs-scielo at the link "Manuscripts with Decisions") and then in "create a resubmission" to resubmit the manuscript. With the resubmission, the manuscript will receive a new ID. The use of this link will accelerate the evaluation since the system will keep all the decisions for the previous ID linked to the new ID. All these actions for an already evaluated manuscript will expedite the assessment.
1. Introduction
The Journal of the Brazilian Chemical Society (JBCS) embraces all aspects of chemistry except education, philosophy and history. It is a medium for reporting selected original and significant contributions to new chemical knowledge. The Journal publishes Articles, Communications, Short Reports, Reviews, Accounts and Letters. The reproduction of figures, schemes and photos already published in other publications, even if these materials have been published by the same authors, requires the copyright permission given by the editor house allowing the publication of the article in the JBCS. For materials (figures, schemes, etc.) under CC-BY license, the copyright permission is not necessary, and the author must include in the manuscript the credits (attribution), see the example: Figure 1. A binary phase diagram for eutectic mixture formation (figure from reference 12 with CC-BY attribution).
1.1 Manuscript types Article should be comprehensive and critical accounts of a work in a given area. Although short articles are acceptable, the Editors strongly discourage fragmentation of a substantial body of work into a number of short publications. Communication should be restricted to reports of unusual urgency and significance or interest. They should be submitted with a statement from the authors as to why the manuscript meets these criteria. A manuscript will not be accepted if, in the opinion of the Editors, the principal content has previously been released or published in any other medium. The communication should not exceed 1500 words or occupy more than 3 pages of the Journal. To estimate the length of a communication, an average sized figure is counted as 100 words and separate formulae and lines of a table are counted as 8 words per line, including headings and horizontal rulings. Title, authors' names and literature references are not counted. Short Report is meant to be a concise terminal report of studies of limited scope. Manuscripts submitted as articles or communications may, in some cases, be accepted as short reports. The standard of quality expected in short reports is the same as in articles. Review is normally invited by the Editors. However, the Editors welcome suggestions for reviews considered suitable for the Journal. Be aware that the topics (items) in the Reviews must be numbered with Arabic numerals. In order to help the Editors in the evaluation of the suitability of a proposed Review, the authors should previously submit by e-mail (help_office@jbcs.sbq.org.br) the following items:
A short Curriculum Vitae (max. 100 words) with photo for each author needs to be added in the end of the main document. Acceptance of the synopsis does not guarantee publication of the final manuscript. It is quite common, in Reviews, the reproduction of figures, schemes and photos already published in other works. Even if these materials have been published by the same authors, copyright permissions need to be given by the editorial office. Account are personalized reviews by individuals or their research groups, dealing with their (important) recent work, and is published only by invitation from the Editorial Board. Like the Review, it may include figures, schemes, structures, etc. The topics in the Account must be numbered with Arabic numerals. In order to help the Editors in the evaluation of the suitability of a proposed Account, authors should previously submit by e-mail (help_office@jbcs.sbq.org.br) a synopsis considering the following items:
In case any reproduction of figures, schemes and photos already published in other journals is included, a copyright permission given by the editorial office of the publisher must be sent to JBCS office. Letter is a medium for the expression of scientific opinions and views normally concerning material published in the Journal, but not for revision/update of the authors' own work. When a Letter polemical in nature is accepted, a reply from the implicated parties will be requested for publication alongside the original Letter. Contributions in this format are intended to be published as soon as possible. No Abstract is required for letters. They should not exceed one printed page in length.
1.2 Before Beginning the Submission
See JBCS Ethical Guides and Publication Copyright in our webpage: http://jbcs.sbq.org.br/ethical_guides
1.3 ORCID
The authenticated ORCID iD is required for the submitting agent. For those that do not have an ORCID identifier, the ScholarOne submission system is integrated to the ORCID
1.4 Collecting Author Contribution in the Submission The ScholarOne-JBCS submission system is configured to use the Taxonomia CRediT to recognize the individual contributions of authors (containing 14 roles), being a required item to the accomplishment of the submission. When adding authors to the submission, you will choose from a list of contributions. Check the author’s role options, then select the level of contribution from the dropdown. The 14 roles according to the Taxonomia CRediT are: Conceptualization, Data curation, Formal analysis funding acquisition, Investigation, Project administration, Resources, Software, Validation, Visualization, Writing original draft and Writing-review & editing. The levels of contribution: Lead, Support, Equal.
1.5 Collecting Author Contribution in the manuscript For manuscript with 6 or more authors, the JBCS requires the specification of the individual contribution of each author in the text. This information, according to the 14 roles from the Taxonomia CRediT, may be added before the Reference, named as Author Contributions, see template.
1.6 Anti-plagiarism Tool The JBCS adopts the use of the anti-plagiarism Tool iThenticate since the end of 2015.
1.7 Manuscript Organization
Authors should present their materials with the utmost conciseness and clarity. The Introduction should clearly and briefly identify, with relevant references, both the nature of the problem under investigation and its background. Extensive reviews of the literature cannot be accepted. In Articles and Short Reports, the Experimental section may precede or follow the Results and Discussion section, but should be separated from it. The addition of a final section at the end of the manuscript, which briefly summarizes the main Conclusions of the work, is recommended and needs to be just after the Results and Discussion section. Descriptions of experiments should be given in sufficient details to enable other researchers to repeat them. The degree of purity of materials should be given, as well as all quantities used. Descriptions of established procedures are unnecessary. Standard techniques and methods used throughout the work should be stated at the beginning of the section in a Materials and/or Methods subsection, in the Experimental section. Apparatus should be described only if it is non-standard. Commercially available instruments should be referred to by their suppliers and models. All new compounds should be fully characterized, which includes spectroscopic data and elemental analyses. High-resolution mass spectra may substitute for elemental analyses if accompanied by unequivocal proof of sample purity (melting points, copies of NMR spectra, etc.). For compounds prepared in enantiomerically pure or enantiomerically enriched form, specific optical rotation must be given. In cases where enantiomeric excess is determined by chromatographic and/or spectroscopic techniques, copies of the appropriate chromatograms and/or spectra should be included as Supplementary Information upon submission of the manuscript. Data associated with specific compounds should be listed after the name of the compound concerned, followed by the description of the preparation, or else presented in tabular form in the Results and Discussion section. All spectra must be included in the Supplementary Information (SI, see Section 8). Many theoretical and computational papers use a routine procedure based on a well-documented method, being it semi-empirical or ab initio. It is then sufficient to name the particular variant, referring to key papers, in which the method has been developed, to cite the computer program used and to indicate briefly any modification made by the author. Complementary data meant to support the analysis of Communications should be included as Supplementary Information (SI, see Section 8). It is the authors' responsibility to obtain permission from other publishers for the reproduction of artwork from other journals in the reviews or in any other type of publication. Such specific Copyright Permissions should be sent to the JBCS Editorial Manager. Suitable acknowledgement of reproduction must be given in the captions.
1.8 JBCS Polity Statements for Preprints
2. Preparation of Manuscripts
General Overview: Font: Times New Roman Font Size: 12 Font Color: Black Spacing: double spaced Pages: numbered consecutively Tables, Schemes, Figures and captions: placed in the text, as close as possible to the first citation. Figures: numbered with Arabic numerals. For full manuscripts containing material previously published in preliminary form, a copy of the previous communication is required and should be included at the end of the manuscript. Maps: insert as Supplementary Information Main sections (Introduction, Experimental, Results and Discussion, Conclusion section) of the manuscript should NOT be numbered, EXCEPT for Account and Review. Supplementary Information (SI): needs to be included at the end of manuscript, after the Conclusions section. It should contain RELEVANT and COMPLEMENTARY DATA to those presented in the manuscript. If new compounds are identified or characterized, all spectra should be included (see Section 8). Graphics/Figures/Schemes: files should be uploaded in the system individually. JBCS preference is for files from original programs since editable files facilitate the correction of details out of JBCS standard. Some suggested extensions: Structures in: *.cdx (ChemDraw); Graphics in: *.opj/org (Origin); *.xls/xlsx (Excel); Others in: *.cdr (CorelDraw); *.tif/jpg (Paint), etc. If you have worked with different programs, please write to help_office@jbcs.sbq.org.br informing which ones were used, and depending we may accept the files. Main document (full): also keep tables/figures/schemes/equations and their legends as close as possible of their first citation. Main document in: *.doc/docx (Word); *.tex (LaTeX, TeX).
Details:
First Page - Graphical Abstract (GA) (see Section 5)
Second Page - Title - Authors' names: full given name, followed by the middle name initial(s) and then by the full last name. An asterisk (*) should follow the name of the corresponding author.
Jailson B. de Andrade,* ,a Marta V. Andrade b and Heloisa L. C. Pinheiro c
Third Page Abstracts: maximum of 150 words for Articles, Accounts and Reviews and 50 words for Short Reports and Communications. Keywords: a minimum of three and maximum of five. Broad-sense words such as "water" should be avoided. The text should start from the third page of the manuscript.
Attention: all nomenclature should be consistent, clear, unambiguous and in accordance with the nomenclature rules established by the IUPAC, the International Union of Biochemistry, the Abstracts Service (see Index Guide to Chemical Abstracts, and https://iupac.org/what-we-do/books/color-books/), the Nomenclature Committee of the American Chemical Society or any other appropriate bodies. Units and symbols should follow IUPAC recommendations. Authors will not be denied any reasonable usage, but if non-SI units are used for critical data or for quantities measured to a high degree of accuracy, final numerical values should also be expressed in SI units. Be sure that all abbreviations are once specified (as near as possible of their first citation).
3. Language, Style and Format
Only manuscripts written in English will be considered. Standard English and American English spellings are allowed but consistency should be maintained within the manuscript. From now on, all authors are expected to send along with their manuscript a statement from a specialized company (or person), attesting that the text was submitted to formal English review. Otherwise, the Editor can, at any time, ask for such procedure to warrant the English precision, conciseness and understanding of the manuscript.
- Conclusions - Supplementary Information (if you have): include the following text just to mention (not to add graphs and data here) the existence of the supplementary data, see the example: Supplementary Information Supplementary data are available free of charge at http://jbcs.sbq.org.br as PDF file. - Acknowledgments - References
4. Guidelines for Illustrations
General Size The authors should think about the illustration size for double column (172 mm) of the journal. But, the font type size of text must be consistent with the illustration since it can be reduced during preparation of the Galley Proof. This is important when choosing symbols for graphics, drawings, charts, photos, etc., be consistent, make your manuscript look nicer: use the same size and same font type in graphics, schemes, etc.
4.1 Graphs and Figures (also see Section 2) Lines and Lettering: Lines should be black and of an adequate and even thickness. Solid, broke, dotted and dot-dash lines should be used in graphics. Particular care should be taken to ensure that the lines in a spectrum are of adequate thickness. Lettering should not be smaller than 7 pt (Times New Roman) and lines not thinner than 0.5 pt. Lettering and lines should be of uniform density throughout the figures. Labeled atoms in ORTEP (or any other) diagrams should have atom numbers in parenthesis, e.g., Fe(1), C(44). Symbols representing physical quantities should be given in italics, e.g., J (Hz), δ (ppm), m/z, etc. Units should be expressed in the appropriate form, e.g., g cm -3 or mol L -1, rather than g/cm 3 or mol/L (see Section 4.5) Graphs - Scales: graphs should have only the minimum necessary scale divisions marked by numerals. - Axis labels should use SI units, separated from quantities (see details in the green book https://iupac.org/projects/project-details/?project_nr=110-2-81 or http://www.sbq.org.br/livroverde/): For graphs, use slashes in X and Y axes to separate axes names from units. For example: 2θ / degree; Temperature / oC; time / min; Size range / mm; Wavenumber / cm -1. Use parentheses only to group a set of units, e.g., Concentration / (mol L -1) ; 10 3 (T/K) -1, etc. Pay close attention to the way decimal values are expressed in English. Employ dots instead of commas. Figures must have a high quality in order to be well reproduced. Use at least a 900 dpi resolution. If necessary, resize to a smaller size to get higher quality. Curves should be labeled (a), (b), (c) etc. and further information be given in the figure legend/caption. Data Points must be shown sufficiently large to be distinguishable. Whenever possible, they should be marked with the following symbols (use alternated full and open symbols): ●, ○, ■, □, ▲, Δ, ♦, ◊ Graphs/Figures should be pasted from their original files (Origin, ChemDraw, Corel etc.) and have an excellent quality. If you have to digitalize (scan) the figures (photos, for instance), choose the following scan options: black & white (B&W), no background and minimum of 300 dpi. If you wish them to be published online in color, send both the colored and B&W versions to the Editorial Office, matching the captions of the figures to accommodate the alternatives. For computer-generated artwork, background or shadings should be avoided.
4.2 Structural Formulae
Figures, schemes 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 or Arial), size of cyclic groups, size and thickness of chemical bonds, and, the most important, authors should use the same standard throughout the work, including all figures, schemes, etc. The following organic group abbreviations may be used: Me, Et, nPr, nBu, sBu, tBu, Ph, CO 2R, CO 2H, iPrOH.
One variable univalent substituent is indicated by R. When more than one independent variable general substituent is present, R 1, R 2, R 3, etc. should be used.
4.3 Photographs
Photographs should be highly contrasted, positive and not mounted. When necessary, the scale should be drawn on the photograph itself and not below. Color prints are rarely reproduced satisfactorily in black and white. Original B&W photographs are preferred to report experimental results, such as electron micrographs or to illustrate special equipment adaptations.
4.4 Tables, Data and Units Tables Format your table to give straightforward information to the reader. Do not use shades or bold lettering. Indicate any extra information as a footnote with letters, e.g., a, b, c, etc. For examples, see any "PDF" files in: http://jbcs.sbq.org.br/forthcoming_papers.asp. Data For negative numbers, ions and equations in text and tables use − (negative symbol) instead of - (hyphen). Examples: Cl −, −0.40, y = a x − b. Units Use International System Units (SI), e.g., m, s, kg, Pa, mol L -1, etc, separated from quantities with a blank space. Example: 300 K, not 300K. See: https://iupac.org/what-we-do/books/color-books/. Note: IUPAC convention recommends to avoid the unit Molar (M), being suggested mol L -1 or mol dm -3, with consistent use throughout your manuscript.
5. Graphical Abstract (GA) and Text for GA
Concerning the JBCS Table of Contents, it is expected from authors careful with their Graphical Abstract (GA) proposition. This image is the one used in the JBCS posts in the social media (Facebook and Instagram) and index, so it is very important to propose a creative figure summarizing the work, and the resolution is fundamental. This way, the figure should summarize the content of the manuscript in a concise, pictorial form, designed to capture the attention of a wide readership. The author should present a new figure, using as an idea a key structure, a reaction, an equation, a concept, a graphic, a theorem, etc. It should be used colors as much as possible and have an artistic and imaginative idea. Short movies are also welcome (as supplementary information (SI)). It is not acceptable photos of commercial equipment in GA or in the text of the manuscripts. Pay Attention: the image should have a 900 dpi resolution (*.tiff / *.jpg or any other image file that can be edited and be 8 cm wide and 4 cm high). Along with the GA figure, insert a short explanatory text about it below (three lines at the most). Take a look at our recent publications whose Table of Contents presents Graphical Abstracts (http://jbcs.sbq.org.br). Therefore, be smart to advertise your manuscript, send a beautiful and appealing graphical image.
6. Equations
When writing equations, use the Word editing equation option or any other equation editor. Equation cannot be added in the main text as image format.
7. How to Cite a Reference throughout the Text Citations should be typed just after punctuation (without space) as superscripts, see the example: example 1: … of the environment.1-8 A behavior… {1-8 as superscripts} INSTEAD OF: … of the environment, 1-8. A behavior… {1-8 as superscripts} INSTEAD OF: … of the environment. 1-8 A behavior… {1-8 as superscripts}

9. Supplementary Information (SI)
This material will be available online in the JBCS Page as PDF file. It should contain relevant and complementary data to those presented in the manuscript. Their format can be: tables, graphs, spectra, films and so on. Any synthesized or identified compound must be accompanied by the spectra used for such identification. This is especially important for Natural Products, Organic and Inorganic Chemistry manuscripts in which the characterization/identification techniques are part of the work.
9.1. Manuscripts including crystallographic data Deposition of Crystallographic Data Prior to the submission of the typescript including crystallographic data, the author(s) should deposit, in the relevant Data Center, the data corresponding to each structure to be reported. Data for organometallic, organic, coordination (Werner-type) and inorganic compounds should be sent to the joint CCDC/FIZ Karlsruhe online deposition service (https://www.ccdc.cam.ac.uk/Community/depositastructure/), in CIF format. More information about the deposit can be obtained from the CCDC/FIZ Frequently Asked Questions (FAQ) homepage: CCDC: Cambridge Crystallographic Data Centre (https://www.ccdc.cam.ac.uk/) FIZ: Fachinformationszentrum (https://www.fiz-karlsruhe.de/).
Deposition Codes
The Data Centers will provide deposition codes for each data set, which should be quoted in the typescript under a Supplementary Information heading before the Acknowledgements. Standard text for CCDC: Crystallographic data (excluding structure factors) for the structures in this work were deposited in the Cambridge Crystallographic Data Centre as supplementary publication number CCDC XXXXXX. Copies of the data can be obtained, free of charge, via https://www.ccdc.cam.ac.uk/structures/.
CheckCIF
During submission of a manuscript to the Journal of the Brazilian Chemical Society, authors should provide CCDC/FIZ reference numbers as Supplementary Information according to the instructions given above. CIF files should not be submitted with the manuscript (only to the suitable Data Center). Any revised CIF generated during the editorial process should be deposited directly with the CCDC before the revised manuscript is submitted to the JBCS. 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 (https://checkcif.iucr.org/) provided by the International Union of Crystallography (IUCr, https://www.iucr.org/). 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.
Preparation of Crystallographic Material
When the manuscript is submitted, the following guidelines should be observed: The Abstract should not contain crystal data, but a concise statement of the main features of the structural results. The following crystallographic data should be given in a paragraph of a Table, in a concise format: 9.1.1 Color, habit and size of the crystal(s) used, behavior of the compound under the data collection conditions. 9.1.2 The chemical formula should correspond to the complete chemical unit encompassing the crystallographic symmetry, the formula weight, F(000), the absorption coefficient and the measured and calculated densities. 9.1.3 The unit cell parameters with esd's and the X-ray wavelength used. 9.1.4 The crystal system, space group and number of chemical units per cell. 9.1.5 Type of diffractometer used and method of data collection, total number of data collected, number of unique reflections, R(int) value, number of observed reflections with cut-off parameter, use or not of absorption correction, transmission factors. 9.1.6 The final results: R, wR, S and the number of parameters refined; treatment of hydrogen atoms; final peak and hole in the last difference map. Only refinements on F2 will be accepted.
Discussion of the Structure
It must include a labeled diagram of the structure, a list of relevant geometric parameters - interatomic bond distances and angles, torsion angles, hydrogen bond parameters, etc. Data of less important parts of the structure, such as ligand sub-groups (phenyl rings, etc.) should be omitted.
9.2. Manuscripts including NMR, IR, mass spectra, etc.
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, at the end of your doc file. A brief mention to the existence of complementary data should be included in the Supplementary Information topic before the Acknowledgments section. Example:
Supplementary Information
Supplementary information (Figure S1-S4, Table S1) is available free of charge at http://jbcs.org.br as PDF file. How to send this type of information: Join all spectra in one SI file. Do not forget to add captions to each one of them, identifying each individual 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&white, without background and 300 dpi at least. Add this file to the end of your manuscript, which should then comprehend one single doc file, containing GA, text with tables and figures, and SI. |
