Submissions

Author Guidelines

The Editor and Editorial Board work on voluntary basis and the publishing process is not as prompt as we would like it to be due to our other duties. Furthermore, we ask that authors do not submit more than two manuscripts per year since the number of published papers is rather limited. Submitting more papers than one only slows the process, which is mostly dependent on the available reviewers willing to do peer review. Also, please keep in mind that based on an abstract we cannot decide whether the manuscript is in the scope of the journal and we do no answer such e-mails.

The initial assessment by the Editorial Board of the manuscript usually takes about ten days. Only then, it is sent to reviewers. This usually takes three months, however in some cases can exceed six months. There is no way of fast tracking by making payments etc. There are no overt or covert fees for publishing in MJCCE. If you find that your manuscript has been archived it means it has been rejected. Check your spam folder for the rejection letter.

In order to submit a manuscript you must register as an author and reviewer to the site. Please provide all required data including the reviewing interests and ORCID for all authors. Manuscripts sent by e-mail will not be considered for publication.

The authors bear the sole responsibility for the content of the contributions. It is assumed that by submitting the paper the authors have not violated any internal rules or regulations of their institutions related to the content of the contri­bu­ti­ons. Submission of a paper implies that it has not been published previously, that it is not under consideration for publication elsewhere, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, without the written consent of the Publisher.

Published statement of human and animal rights

When reporting experiments on human subjects, including research on identifiable human material and data, authors must submit a statment whether the procedures followed were in accordance with the ethical standards of the responsible committee on human experimentation (institutional and national) and with the Helsinki Declaration. These studies must be approved by an appropriate institutional review board or committee, and informed consent must be obtained from subjects. The Methods section of the paper must include: 1) a statement of protocol approval from an institutional review board or committee and 2), a statement that informed consent was obtained from the human subjects or their representatives. If doubt exists whether the research was conducted in accordance with the Helsinki Declaration, the authors must explain the rationale for their approach and demonstrate that the institutional review body explicitly approved the doubtful aspects of the study.

When reporting experiments on animals, authors should indicate whether the institutional and national guide for the care and use of laboratory animals was followed.

Conflicts of interest

The Editorial Board of MJCCE should be informed of any significant conflict of interest that editors, authors or reviewers may have, in order to determine if any action may be appropriate (such as adding a declaration of an author’s conflict of interest to a published piece, or disqualifying a reviewer). Conflicts of interest are almost inevitable and it is not intended to attempt to eliminate these. If authors are in any doubt about declaring a potential conflict, they should remember that if it is revealed later – especially after publication – it could cause more problems than simply declaring it at the time of submission. Undeclared conflicts of interest could lead to a corrigendum or, in the most serious cases, a retraction.

Preparation of manuscript

Prepare the entire manuscript in double-space with Times New Roman font, on A4 size numbered pages with mar­gins of 2.5 cm on all sides. Use one column and do not use any special formatting, especially for the tables and figures. Avoid using nonstandard fonts for special characters, even the Greek letters should be from the Times New Roman Unicode font. Do not use footnotes.

Manuscript should contain title, authors’ na­mes and addresses, abstract, key words, intro­duc­tion, experimental or theoretical background, re­sults and discussion, conclusions, acknowledgement (optional) and references.

Title. It should be brief but informative and should define the subject of the manuscript. Avoid abbreviations in the title.

Authorship. List the first and last name of each author. Omit professional and official titles. Give the complete mailing address of each author. For the corresponding author include an e-mail address. The name of the corresponding author should carry an asterisk.

In the metadata field when submitting the manuscript, include all data for all authors. This is important since indexing services, such as Scopus, use the metadata and not the ones given in the manuscript.

Abstract. Each manuscript should have an abstract of about 150–250 words. It should give the aim of the research, methods or procedures, significant results and conclusions. Any abbreviations used in the abstract should be defined.

Key words. Up to five key words or phrases should be given to facilitate indexing and on-line searching.

Introduction. The most important previous results related to the problem should be reviewed avoiding a detailed literature survey, and the aim and importance of the research should be clearly stated.

Experimental section. This section should contain a description of the materials used and methods employed in form, which makes the results reproducible, but without detailed description of already known methods.

Manuscripts that are related to theoretical studies, instead of experimental section should contain a sub-heading theoretical background where the necessary details for verifying the results obtained should be stated.

Results and discussion. The authors should discuss their findings, postulate explanations for the data, elucidate mo­dels and compare their results with those of other works. Irrelevant comparisons and specula­tions unsupported by the new information presented in the manuscript should be avoided.

Tables. They should be given with a suitable title and should be numbered consecutively with Arabic numerals. Footnotes to tables should be typed below the table and should be referred to by superscript lowercase letter. The tables should be imbedded in the manuscript. If necessary, the tables can be in landscape mode with font size not more than one point smaller than the main text in the paper.

Figures. Figures (photographs, diagrams and schemes) are encouraged to be in color and should be numbered consecutively with Arabic numerals with a caption describing the figure. They should be imbedded in the text (do not worry about page breaks; as a matter of fact avoid any such formatting). The size of the symbols for the physical quantities and units as well as the size of the numbers and letters used in the reduced figures should be comparable with the size of the letters in the main text of the paper. Each figure or group of figures should be planned to fit, after appropriate reduction, into the area of either one or two columns of text. The maximum finished size of a one-column illustration is 8.0 cm and that of a two-column illustration is 17.0 cm width. Make sure you use uniform lettering and sizing of your original artwork. If required by the technical editor all figures should be available as TIFF or JPG files with minimum 300 dpi or higher resolution.

IUPAC recommendations should be followed. Detailed instructions are given in relevant IUPAC publications:

• Brief Guide to the Nomenclature of Inorganic Chemistry, Red Book Essentials, IUPAC, 2016.
• IUPAC Nomenclature of Organic Compounds, Recommendations 1993.
• Quantities, Units and Symbols in Physical Chemistry - 3^nd edition, The Royal Society of Chemistry, 2007.

SI units as recommended by IUPAC should be used. Where there are special reasons for making an exception to this rule, it is recommended to define the units used in terms of SI units. In tabulating the numerical values of physical quantities, or labeling the axes of graphs, the quotient of a physical quantity and a unit should be used in such a form that the values to be tabulated are pure numbers.

Examples:

• T/K or Temperature/K
• 10³ (T/K)^–1
• ln (p/kPa)
• (I_m/mmol kg^–1)^1/2

Percents and per mills, although not being units in the same sense as the units of dimensioned quantities, can be treated as such. Unit symbols should never be modified (for instance: w/w %, vol.%, mol.%) but the quantity measured has to be named, e.g. mass fraction, w = 95 %; amount (mole) fraction, x = 20 %.

Latin words should be italicized, as for example: et al., i.e., in vivo, ibid., vs.

Double subscripts or superscripts should be avoided whenever possible.

Data for new compounds should be quoted as follows: yield, melting (boiling) point, UV absorpion, NMR spectra, mass spectrum and elemental analysis, e.g. 7 g (65 %); m.p. 77–78 °C; UV(EtOH) λ_max/nm: 228 and 262 (logε/dm³ mol^–1 cm^–1: 4.23 and 3.92; ¹H NMR (CdCl₃) δ/ppm: 2.30 (s, 3H, Me), 4.51 (d, 1H, 1,2 J_1,2 = 3.2 Hz, H–3); ¹³C NMR (CdCl₃) δ/ppm: 160 (C–5), 120 (C–2); MS m/z: 264 (M+, 100 %) and 246 (M⁺–18).

Analysis. Calcd. mass fractions of elements, w/%, for C₁₈H₁₃N₃O₅S (M_r = 383.38) are: C 56.39, H 3.42, N 10.96, O 20.87, S 8.36; found: C 56.31, H 3.62, N 10.76, O 20.60, S 8.19. When describing more than 4 or 5 compounds, the data are best presented as a table.

Formulas and equations. Chemical equations should be balanced and numbered consecutively along with mathematical equations or other mathematical expressions. All of them should be marked with Arabic numerals in parenthesis in the right hand margin. The use of equation editor (Word) for typesetting the equations is recommended. Stro­kes (/) should not be used instead of parentheses.

Crystal structure determination(s). The authors should deposit the crystallographic data with the Cambridge Crystallographic Data Centre (organic and metal-organic structures) or with the Fachinformationszentrum Karlsruhe (inorganic structures). The addresses are:

• Cambridge Crystallographic Data Centre, 12 Union Road, Cambridge CB2 1EZ, UK

https://www.ccdc.cam.ac.uk/deposit/

Deposition number should be submitted together with the manuscript and an appropriate note should be put in the paper.

Conclusion. Give only the most important conclusions reached from the investigation in clear statements.

Acknowledgement. Financial support, advice or other kinds of assistance can be included in this section.

References. Literature references should be numbered and listed as superscripts in order of citation in the text. They should be selective rather than extensive with the exemption to review articles. Avoid references to works that have not been peered-reviewed. Citation of a reference as “in press” implies that it has been accepted for publication. Abbreviations of the titles of the periodicals should be in accordance with Chemical Abstracts Service Source Index (CASSI). If using reference managers such as Mendelay, Paperpile, OneNote, BibGuru etc. you can use the style for Accounts of Chemical Research.

All references should contain a DOI link (if they have one).

The surname of one or two authors may be given in the text, whereas in case of more than two authors they should be quoted as, for example, Eygeris et al.¹ References should be cited as follows:
