The words Introduction, Review of Literature, Definitions (if any), Materials and Methods or Methodology, or Development, or Background, Results and Discussion of Findings, Conclusions must be written in capital letters, Arial, font size 12, left alignment, bold.
INTRODUCTION: The introduction must clearly state the problem, the reason for doing the work, the hypotheses or theoretical predictions under consideration, and the essential background. It should not contain equations or mathematical notation. A brief survey of the relevant literature so that a non-specialist reader could understand the significance of the presented results. A good introduction should ideally have 3-5 well-explained paragraphs and should finishing pointing out the AIM of the study.
MATERIALS AND METHODS OR METHODOLOGY, OR DEVELOPMENT: Provide sufficient details to the reader to understand how the study was performed. The technical description of methods should be given when such methods are new. It is generally recommended that the materials and methods should be written in the past tense, preferably in the passive voice. In this section, ethical approval, study dates, number of subjects, groups, evaluation criteria, exclusion criteria and statistical methods should be described sequentially. The following questions should be absolutely provided: the beginning, and termination dates of the study period; number of subjects/patients/experimental animals . enrolled in the study; has the approval of the ethics committee been obtained? Study design (prospective, retrospective or other); still additional features of the study design (cross-sectional) should be indicated. Apart from this, other types of study designs (randomized, double-blind, placebo-controlled or double-blind, parallel control.) should be revealed. Before you finish your manuscript, ask yourself the following questions about your Materials and Methods section to ensure that you have included all important information. Is there sufficient detail so that the experiments can be reproduced? Is there excess information that could be removed without affecting the interpretation of the results? Are all the appropriate controls mentioned? Are all appropriate citations included? Is the source of each reagent listed? The Materials and Methods section is a vital component of any manuscript. This section of the report gives a detailed account of the procedure that was followed in completing the experiment(s) discussed in the paper. Such an account is very important, not only so that the reader has a clear understanding of the experiment, but a well written Materials and Methods section also serves as a set of instructions for anyone desiring to replicate the study in the future. Considering the importance of "reproducible results" in science, it is very relevant why this second application is so vital. Some general rules for Methods sections are:
- It should be clear from the Methods section how all of the data in the Results section were obtained;
- The study system should be clearly described. In medicine, for example, researchers need to specify the number of study subjects; how, when, and where the subjects were recruited, and that the study obtained appropriate ‘informed consent’ documents; and what criteria subjects had to meet to be included in the study;
- In most cases, the experiments should include appropriate controls or comparators. The conditions of the controls should be specified.
- The outcomes of the study should be defined, and the outcome measures should be objectively validated.
- The methods used to analyze the data must be statistically sound.
- For qualitative studies, an established qualitative research method (e.g. grounded theory is often used in sociology) must be used as appropriate for the study question.
- If the authors used a technique from a published study, they should include a citation and a summary of the procedure in the text. The method also needs to be appropriate for the present experiment.
- All materials and instruments should be identified, including the supplier’s name and location.
- The Methods section should not have information that belongs in another section (such as the Introduction or Results).
- You may suggest if additional experiments would greatly improve the quality of the manuscript. Your suggestions should be in line with the study’s aims. Remember that almost any study could be strengthened by further experiments, so only suggest further work if you believe that the manuscript is not publishable without it.
RESULTS AND DISCUSSION OR FINDINGS: Results should be presented concisely. Also, point out the significance of the results, and place the results in the context of other work and theoretical background. The results and discussion sections are one of the challenging sections to write. It is important to plan this section carefully as it may contain a large amount of scientific data that needs to be presented clearly and concisely. The purpose of the Results section is to present the key results of your research. Results and discussions can either be combined into one section or organized as separate sections. Use subsections and subheadings to improve readability and clarity. Number all tables and figures with descriptive titles. Present your results as figures and tables and point the reader to relevant items while discussing the results. This section should highlight significant or interesting findings along with P values for statistical tests. Be sure to include negative results and highlight the potential limitations of the paper. The results and discussion section of your research paper should include the following: Findings; Comparison with prior studies; Limitations of your work; Casual arguments; Speculations; Deductive arguments.
CONCLUSION: Summarize the data discussed in the Results and Discussion or Findings section showing the relevance of the work and how different it is from other researches. Also, point out the benefits and improvements that can be observed to develop new science standards that can change something in the related field.
ACKNOWLEDGMENTS: (if any) These should be placed in a separate paragraph at the end of the text, immediately before the list of references. It may include funding information too.
REFERENCES: References should be cited in the text using the name-and-year system (Author, year) (APA FORMAT). Alternatively, the author's surname may be integrated into the text, followed by the year of publication in parentheses. Examples: Grasslands are regarded as important foraging areas for many insectivores in Europe, such as birds (Vichery, 2001; Barnet et al., 2004), bats (Guttinger, 1997) or amphibians and reptiles (Langton and Burton, 1997). However, the knowledge of the overall arthropod availability in such grasslands is scarce, since many studies about insect populations concentrate on extensive grasslands on poor, dry or wet soils include only few species or systematic groups (Ellgsen et al., 1997; Gibson et al., 1992; Hansel and Plachter, 2004; Manhart et al., 2004; Kruess and Tscharntke, 2002a, b; Wingerden et al., 1992; Sjodin, 2007a, b; Perner et al., 2005). Carbon dioxide produced by the combustion of biodiesel can be recycled by photosynthesis, thereby minimizing the impact of biodiesel combustion on the greenhouse effect (Korbitz, 1999; Agarwal and Das, 2001).
Cite only essential resources, avoid citing unpublished material. References to papers "in press" must mean that the article has been accepted for publication. At the end of the paper list references alphabetically by the last name of the first author. Please, list only those references that are cited in the text and prepare this list as an automatically numbered list. The word References with size 12, bold, capital letters, left alignment

For different types of references than scientific papers, the Journal recommends visiting the websites below for more detailed information.
The number of pictures (including graphs and diagrams) should not exceed 15 and should be submitted either in JPEG or PNG formats. All photographs, charts, and diagrams should be numbered consecutively (e.g., Figure 1, Figure 2, Figure 3,…..) in the order in which they are referred to in the text. The caption must appear below the figure (size 11, bold, italic) and should be sufficiently detailed to enable us to understand apart from the text. Explanation of lettering and symbols should be also given in the caption and only exceptionally in the figures. Figures should be of good quality. Scanned figures should be at a resolution of 800 dpi/bitmap for line graphs. Diagrams containing chemical structures should be of high graphical quality and always be of the same size so that they can be uniformly reduced. Figures should have a maximum width of one Journal column (8.5 cm) to be inserted on the body of the text so that they can be applied to the standards of the Journal. If the figures exceed 8.5 cm, they will be placed at the end of the article. Also, authors may be requested to submit each figure as an image file in one of the following formats: jpeg or png. For pictures, graphs, diagrams, and tables identical to material already published in the literature, authors should seek permission for publication from the companies or scientific societies holding the copyrights and send it to the editors of Periódico Tchê Química along with the final form of the manuscriptImportant summarized information:
- Upload the images either in JPEG or PNG formats. Poor quality and resolution figures will not be accepted. Pay attention when scanning or making print screen of an image. In these cases, the resolution is usually low and it becomes challenging to the reader to see the information of the figure;
- Figures should be numbered consecutively, in Arabic numerals, according to the order in which they have been first cited in the text;
- All information including numbers and symbols should be clear and of uniform size. The lettering for figures should be large enough to be legible either in the two or one column format;
- Any details to point out a specific view like symbols, arrows, or letters used in photomicrographs should contrast with the background;
- Titles and detailed explanations belong in the legends for illustrations not on the illustrations themselves.
- When graphs, scatter-grams or histograms are submitted the numerical data on which they are based should also be supplied and clear enough.
- The photographs and figures should be trimmed to remove all the unwanted areas. Also, if photographs of individuals are used, their pictures must be accompanied by written permission to use the photograph.
- If a figure has been published elsewhere, acknowledge the source and submit written permission from the copyright holder to reproduce the material. A credit line should appear in the legend for such figures.
- Legends for illustrations: When symbols, arrows, numbers, or letters are used to identify parts of the illustrations, identify and explain each one in the legend. Explain the internal scale (magnification) and identify the method of staining in photomicrographs when suitable;
- The Journal reserves the right to crop, rotate, reduce, or enlarge the photographs to an acceptable size.
Tables should be self-explanatory and should not duplicate textual material. They should be mentioned in the text, numbered consecutively (e.g., Table 1, Table 2, Table 3,....), and accompanied by a title at the top (size 11, bold, italic). Please insert all the tables in the text and do not enclose huge tables that cannot fit within the page margins. Other important considerations.
- Tables with more than 15 columns and 30 rows are not acceptable.
- Number tables, in Arabic numerals, consecutively in the order of their first citation in the text and supply a brief title for each.
- Place explanatory matter in footnotes, not in the heading.
- Explain in footnotes all non-standard abbreviations that are used in each table. If necessary, use symbols to explain and make all abbreviations clear to the reader.
- Obtain permission for all fully borrowed, adapted, and modified tables and provide a credit line in the footnote.
- Tables with their legends should be provided at the end of the text after the references. The tables along with their number should be cited at the relevant place in the text.
- In the text, do not use Tab. For an abbreviation of a Table. Write Table 1, Table 2 instead of Tab.1, Tab.2;
7. MATHEMATICAL EXPRESSIONS
In general, minimize unusual typographical requirements, use solidus, built-up fractions. Avoid lengthy equations that will take several lines (possibly by defining the terms of the equation in separate displays). For drawing equations, please use the Equation Editor of Word, if possible. Make subscripts and superscripts clear. Display only those mathematical expressions that must be numbered for later reference or that need to be emphasized. The equations displayed should be consecutively numbered throughout the paper. The numbers should be placed in parentheses on the right of the equation, e.g. (Eq. 1).
8. SUPPLEMENTARY MATERIAL
Any Supplementary material (extra figures, tables, diagrams, appendix, abbreviations list) should be placed at the end of the manuscript and indicated as such. All supplementary material should also be cited in the text.
Editors, at any time of the editing process, may ask authors to split off part of the manuscript, presenting it as supplementary material.
