    The authors declare no conflicts of interest.

12. References

    Must follow IEEE citation style with minimum 25 recent references. Tools such as Mendeley, Zotero, EndNote are recommended.

For review articles, experimental sections are not required and content should be thematic and analytical.

• Title, author information, affiliation, and abstract remain mandatory
• The introduction should define the scope and importance
• Content organized into thematic sections
• Include critical comparison
• Highlight research gaps and future directions
• Conclusion summarizes contributions
• Minimum references ≥ 40

3. Graphical Abstract

A graphical abstract is mandatory and represents a visual summary of the research.

• Clearly illustrates concept, method, and outcome
• Submitted separately
• Format: JPG or PNG
• Minimum size: 500 × 800 px
• Readable font (Roboto recommended)
• Minimal text

Layout should follow logical flow for readability.

Illustrations Graphical Abstract

4. Abstract

Abstract must be a single paragraph (150–250 words) containing:

• Background
• Methods
• Results
• Conclusion

No citations, equations, or undefined abbreviations are allowed.

5. Introduction

The Introduction section must provide a clear scientific background of the study and establish the research context within existing literature.

• Explain the research background and global relevance
• Identify gaps in previous studies
• State the novelty and contribution of the study
• Clearly define research objectives or hypotheses

This section should be supported by recent and credible references to justify the importance of the study.

6. Materials and Methods

The Methods section must describe the research design and procedures in sufficient detail to ensure reproducibility.

• Specify materials, instruments, and chemicals used
• Explain experimental design or simulation approach
• Describe data collection and analysis methods
• Include statistical or computational techniques used

Clarity and completeness are essential so that other researchers can replicate the study.

7. Results and Discussion

This section presents the main findings of the research and interprets their scientific significance.

• Present results clearly using tables, figures, or graphs
• Provide scientific interpretation of the findings
• Compare results with previous studies
• Explain implications for theory and practice

The discussion should not repeat results, but instead provide critical analysis and insight.

8. Conclusion

The Conclusion section summarizes the main findings and highlights the contribution of the study.

• Summarize key research outcomes
• Highlight scientific contribution and novelty
• Avoid repeating abstract or detailed results
• Provide recommendations or future research direction

The conclusion should be concise, clear, and directly address the research objectives in one paragraph.

9. Mathematical and Chemical Notation Standards

All equations and chemical expressions must follow international scientific standards to ensure clarity and reproducibility.

• Equations must be numbered sequentially (1, 2, 3, ...)
• Variables must be written in italic
• Units must be upright (non-italic)
• Use SI units consistently throughout the manuscript
• Use MathType or Microsoft Equation Editor (recommended)

Correct formatting examples:

• T / K, P / Pa, j / mA cm⁻²
• Chemical formulas must follow IUPAC conventions
• Use proper subscript and superscript notation

10. Heading Format Example 

Use the following heading structure to ensure consistency in your writing:

• Heading 1: 12pt, bold, dark green (#1f4d36)
• Heading 2: 11pt, bold, dark green
• Heading 3: 11pt, semi-bold, dark green
• Consistency: Use hierarchical numbering (1 → 1.1 → 1.1.1)

11. Figures and Tables

• Tables must be editable (not image-based)
• Figures must be high resolution (≥300 dpi)
