✨Instructions for Manuscript Preparation

To maintain the quality and consistency of submitted manuscripts, authors are expected to carefully follow the formatting and submission guidelines outlined below. These include the required structure and components of the article, page and font specifications, proper formatting for tables and figures, and guidelines for writing conclusions and acknowledgments. Authors must also adhere to proper referencing practices using the IEEE style, supported by a reference manager (e.g., Mendeley, EndNote, or Zotero), and ensure that all cited sources are recent and relevant. Additionally, all manuscripts must undergo plagiarism checking through Turnitin, with a similarity score not exceeding 20%. Please review and revise the manuscript as needed before final submission to ensure compliance with these standards.

  • Manuscript must consist of the following scientific article components (subheadings in sequence), i.e.: (a) Article Title, (b) Author's Name (without title), (c) Author’s Affiliate Address, (d) Abstract and Keyword, (e) Introduction, (f) Methodology, (g) Results and Discussion, (h) Conclusion, (i) Acknowledgments (if any), and (j) References.

  • Or the bibliography, IEEE style is written according to the rules of writing. All references used in writing in the bibliography be numbered in accordance with the alphabetically, not the appearance of the article.

  • Referral source in the form of literature must be published 5-10 years. References used are the primary source in the form of research articles in journals or research reports, books or articles that are linked from the official source. To maintain the consistency of the way of reference, quoting and writing a bibliography we suggest using standard reference.

  • Using a reference manager application is very important to maintain consistency and accuracy of citations in your manuscript. If you don't already have an account with your preferred reference manager app (such as EndNote, Mendeley, or Zotero), please register on their official site. For example, for Mendeley, register here (https://www.mendeley.com/reference-management/reference-manager). The following is a tutorial on using Mendeley.

Authors are expected to ensure that Turnitin checking results do not exceed this limit. If there are parts that are highly similar, please revise and correct them before resubmitting.

✨Graphical Abstract

Graphical abstract is a one-image file containing the main depiction of the authors work and/or conclusion and must be supplied along with the manuscript. It must enable readers to quickly gain the main message of the paper and to encourage browsing, help readers identify which papers are most relevant to their research interests.

✨Introduction

The rapid increase in energy consumption, especially in the transportation sector, has led to an energy crisis that has resulted in a decrease in fossil fuel supplies and an increase in environmental pollution [1]. The paper should be organized into logical parts or sections. Any subsection is given a brief numbered heading. The contents include the introduction that should clearly define the nature of the problem, and the references should be made to previously published papers. Theoretical, experimental, results, discussions and conclusions form the main sections of the paper. The theoretical section extends the analytical background of the article and develops a new formulation of the problem. Calculations are achieved here using the developed equations and the modifications should be pointed out. Depending on the suggested research methods, the experimental investigation is achieved, using the testing instruments or design and manufacturing a test rig. Materials and methods are detailed here. In the results and discussions section, the significance of the obtained results should be pointed out and the citations and the discussions of the kinds of literature should be avoided in this section. Sometimes results and discussions are combined in one section.

✨Research and Methodology

2.1 Materials The theoretical section extends the analytical background of the article and develops a new formulation of the problem. Calculations are achieved here using the developed equations and the modifications should be pointed out. They should be described with sufficient detail to allow others to replicate and build on published results. Please state manufacturer, city and country from where materials have been sourced.

2.2 Experiments The reactors consist of a centrally oriented conversion chamber within its’ set-up and possessing several small air holes at the base. The chamber houses the feed to be converted while the combustion fuel for heat generation occupies the ‘heating gap’ between the chamber and the reactor itself.

2.3 Product characterization The products (biomass biochar and hybrid biochar) recovered from the process were characterized to ascertain some of their properties using Scanning Electron Microscope with energy Dispersive X-ray Spectroscopy (SEM-EDS), Fourier Transform Infra-Red Spectroscopy (FTIR) and Brunauer-Emmet-Teller (BET) analysis. Scanning Electron Microscopy (SEM, Phenom proX, Phenom-World BV, Netherlands) was used to study the surface morphology of the particles of the biochar. A double adhesive was placed on a sample stub. The sample was sprinkled on the sample stub and subsequently taken to a sputter coater (quorum-Q150R Plus E) and coated with 5 nm of gold.

✨Results and Discussion

This section focused on the precise description of the experimental or theoretical results. The interpretation of the results and their conclusions should also present in this section. Authors should discuss the results and how they can be interpreted in viewpoint of research works found in the literature and of the working hypotheses. The results and their implications should be discussed in the broadest context possible.

✨Conclusion

A conclusion should point out the distinguished results of the achieved work and do not replicate the abstract. A conclusion may suggest recommendations for work extension and new applications (1 Paragraph).

✨Acknowledgement

Acknowledgments may be directed to individuals or institutions that have contributed to the research or a government agency, or This research received no specific grant from any funding agency in the public, commercial, or not-for-profit sectors.

✨Designation of Physical Quantities and Units

IUPAC recommendations for the naming of compounds should be followed. SI units, or other permissible units, should be employed. The designation of physical quantities must be in italic throughout the text (including figures, tables and equations), whereas the units and indexes (except for indexes having the meaning of physical quantities) are in upright letters. They should be in Times New Roman font. In graphs and tables, a slash should be used to separate the designation of a physical quantity from the unit (example: p / kPa, j / mA cm-2, T0 / K, t / h, ln (j / mA cm-2)…). Designations such as: p (kPa), t [min]…, are not acceptable. However, if the full name of a physical quantity is unavoidable, it should be given in upright letters and separated from the unit by a comma (example: Pressure, kPa; Temperature, K; Current density, mA cm-2…).. Please do not use the axes of graphs for additional explanations; these should be mentioned in the figure captions and/or the manuscript (example: "pressure at the inlet of the system, kPa" should be avoided). The axis name should follow the direction of the axis (the name of y‑axis should be rotated by 90°). Top and right axes should be avoided in diagrams, unless they are absolutely necessary.

For more details see:
https://iupac.org/wp-content/uploads/2019/05/IUPAC-GB3-2012-2ndPrinting-PDFsearchable.pdf

Latin words, as well as the names of species, should be in italic, as for example: i.e., e.g., in vivo, ibid, Calendula officinalis L., etc. The branching of organic compound should also be indicated in italic, for example, n-butanol, tert-butanol, etc.

Decimal numbers must have decimal points and not commas in the text, tables and axis labels in graphical presentations of results. Thousands are separated, if at all, by a comma and not a point.

Mathematical and chemical equations should be given in separate lines and must be numbered, Arabic numbers, consecutively in parenthesis at the end of the line. All equations should be embedded in the text except when they contain graphical elements (tables, figures, schemes and formulae). Complex equations (fractions, integrals, matrix…) should be prepared with the aid of the Microsoft Equation 3.0 (or higher) or MathType (Do not use them to create simple equations and labels). Using the Insert -> Equation option, integrated in MS Office 2010 and MS Office 2013, as well as insertion of equation objects within paragraph text IS NOT ALLOWED.
