The submission requires a Title page, a blinded manuscript, and a graphical abstract.

1. Submission of Manuscripts

The Journal of Metals, Materials and Minerals (JMMM) welcomes submissions of high-quality, original manuscripts in the field of materials science and engineering. Submissions must be written in English and must not have been published or be under simultaneous consideration elsewhere.

The journal accepts the following types of contributions:
1. Original research articles
2. Literature reviews (3,000–10,000 words)

Authors are requested to submit manuscripts via the online submission system at:
https://jmmm.material.chula.ac.th/

All submitted manuscripts will undergo double-blind peer review by at least two independent reviewers to evaluate technical merit, scientific content, and relevance. Revisions may be required before final acceptance.

The final decision on publication is made by the Editors.

After acceptance, authors may be asked to submit revised files and high-resolution artwork as needed for production.

2. Manuscript Preparation

- Length: Manuscripts should generally be less than 10,000 words (excluding references), although longer papers may be considered in special cases.
- Font: Use a 12-point Times New Roman font.
- Numbering: All pages must be numbered consecutively.
- Figures:
  - Insert figures within the text near where they are first cited.
  - Accepted formats: TIF or PNG with a minimum resolution of 300 dpi (600 dpi recommended).
- Tables:
  - Place tables within the text and number them consecutively.

3. Manuscript Format

Follow this sequence when preparing your manuscript:

1. Title
2. Authors
   - Use full first name, middle name (if applicable), and last name for all authors. Indicate the corresponding author with an asterisk (*) and provide a valid email address.
3. Affiliations
   - Include full institutional affiliations for all authors.
4. Abstract
   - A concise summary (max 250 words) of the objectives, methodology, key results, and conclusions.
5. Keywords
   - Provide a maximum of 5 keywords, separated by semicolons.
6. Main Text
   - Recommended structure:
     - 1. Introduction
     - 2. Experimental Details / Materials and Methods
     - 3. Results and Discussion
     - 4. Conclusion
7. Acknowledgements (if applicable)
8. References
   - Use IEEE citation style with the following specifications:
     - Journal names must be written in full (not abbreviated).
     - All author names must be listed (do not use "et al.").
     - Reference numbers should appear in square brackets [1] and be listed in order of citation.

4. Proofs

Galley proofs will be sent to the corresponding author by email. Proofs should be reviewed and returned within 48 hours. Corrections should be limited to typographical or formatting errors. Substantive changes to the content will not be allowed at this stage.

5. Ethics Statement

Authors must adhere to ethical research and publication standards, including but not limited to:
- Originality of the work
- Proper citation and acknowledgment
- No plagiarism or duplicate submission

If AI tools (e.g., for writing or image generation) were used in manuscript preparation, authors must declare their use transparently.

Offprints
The journal makes no page charges. The corresponding author will be provided with a PDF of the article via e-mail at no cost.

SI Units and Usage Guidelines

Authors must use the International System of Units (SI) throughout their manuscripts. SI units ensure clarity, consistency, and international understanding of scientific content. Authors should adhere to the following guidelines:

• Use correct SI unit symbols (e.g., µm for micrometer, not microns; s for seconds, not sec).
• Include a space between the number and the unit (e.g., 25 °C, not 25°C).
• Maintain consistent use of units and avoid mixing SI and non-SI units.
• Scientific notation is preferred for very large or small values (e.g., 1.2 × 10⁵ Pa).
• Use Roman (upright) type for unit symbols and italicize only variables.

Examples of Correct SI Usage

• Length: 5 µm
• Temperature: 25 °C
• Pressure: 1.2 × 10⁵ Pa
• Energy: 10 kJ/mol
• Speed: 20 m/s
• Concentration: 2.5 × 10⁻³ mol/L
• Density: 1.2 g/cm³ or 1200 kg/m³
• Percentage: (70 ± 5) %
