Aim and Scope

The Nigerian Journal of Technological Development (NJTD) publishes high-quality articles focusing on all aspects of Engineering and Applied Sciences. All manuscripts will be double blind peer-reviewed and if found suitable, published according to the subject matter, either as full length research articles or review papers.

Preparation of the Manuscript

Manuscript should be written in English Language and typed in 12 point font size using Times New Roman in double-line spacing on A4 paper. A margin of 25 mm should be left at the sides. The paper should not exceed twenty (20) pages, including figures and tables. The text should be in single-column format.

Title Page  

The title page should contain only the title of the article, authors’ names and contact details such as institutional affiliations, corresponding author’s email address and phone number. The page is also to contain the abstract of the article and the list of three suggested reviewers. The title page should be uploaded as a supplementary document on the Author’s portal during the submission process. The file containing this document should be named Title_Page. The Author Contributions should be included on the title page.

The Anonymised Manuscript

The manuscript should contain the title of the article, the abstract, and five or six keywords. However, it must NOT contain name(s), and address(es) of author(s), and e-mail addresses and telephone number of the corresponding author. These information will be supplied on the online submission platform in addition to the title page. This file should be named Manuscript and to be uploaded on the portal during submission. The manuscript should be organised under the following headings:

The Article Title

A good title should be concise, accurate, and informative, and should inform the reader exactly what the article is all about. It is vital to incorporate some relevant keywords in your title to make your article more discoverable in online searches. Please note that the article title should not exceed seventeen (17) words and should be in title case letters.


The abstract is a brief summary of the research work, which is usually in a paragraph. It should clearly define the problems of study, methodology adopted, results and findings. Citation of previous works are not allowed in the abstract. Abstracts are expected to be stand-alone and capable of providing fast and complete, yet short information about the article. Articles to be submitted to NJTD must have a maximum of 200 words. Authors should pay attention to this word limit!


Five or six relevant keywords should be provided on the manuscript.


Symbols and abbreviations should be defined where first mentioned. If the symbols are many, a “Notation” defining the symbols must be included between the abstract and Introduction. SI units should be used.


This should include the background to the study, a brief review of literature and clearly-stated objectives. The last paragraph should delve into the contributions of the work and structure of the rest of the paper.


The mathematical principles or theories used should be included as appropriate.


This section should include apparatus and equipment setup, work materials, design, experimental methods, as applicable.

  1. Sub-section One

The heading of a sub-section should be in title case letters as illustrated here. In other words, the first letter of an important word must be in upper case letter.

  1. Sub-section Two

The introductory statements should be in the normal 12 point font size. A sub-section may have sub sub-section which are illustrated below in 1) and 2).

1) Sub sub-section one

A sub sub-section heading should have a sentence case in which case it is only the first letter of the heading that would be in upper case letter. Others will be in lower case letters.

2) Sub sub-section two

Same as 1) above.


Results could be presented in descriptive, tabular or graphical form. Information presented in tables should not be repeated as figures. Discussion should be focused on the interpretation of experimental findings. This may be broken down into different sub-sections and sub sub-sections as discussed in Section III above.

  1. Tables and Figures

Tables and Figures should be placed as close as possible to the first place of reference in the text. References should be made to all the tables and figures and each must be discussed in the manuscript. Authors should endeavour to supply very high quality figures. Editable charts must be provided while “copy and paste” figures must be avoided as much as possible.

It should be noted that good quality articles can be denied publication in NJTD on account of poor quality figures and tables.

  1. Equations

All equations, whether mathematical or chemical, are considered as text and should be typed using Microsoft Equation 3.0 or MathType in Word. These equations should be numbered sequentially and should be referenced and discussed in the text. Equation numbers should be enclosed in parentheses and made to align towards the right hand margin of the text. If detailed derivation is needed, it is to be placed in an appendix. Each equation should appear on its own line and should be indented from the left margin of the text.


The conclusion should be a brief summary of findings. It should clearly state the contributions, relevance of the findings and recommendations, as appropriate. It is usually reported in the past tense form.


For transparency, authors should submit an author statements outlining individual contributions to the paper using the following roles: Conceptualization; Data curation; Formal analysis; Funding acquisition; Investigation; Methodology; Project administration; Resources; Software; Supervision; Validation; Visualization; Writing - original draft; Writing - review & editing.

For example, S. O. Sanni: Conceptualization, Methodology, Software, Validation, Writing – original draft, Writing – review & editing. M. F. Akorede: Supervision, Writing – original draft, Writing – review & editing. G. A. Olarinoye: Writing – review & editing.


Acknowledgement of the individuals, institutions or research granting body who provided help during the research should be collated in a separate section at the end of the article before the references and should, therefore, not be included on the title page, as a footnote to the title or otherwise.

NOTE: Author Contributions and Acknowledgement should initially be included on the title page of the manuscript until after paper acceptance.


The Harvard system (alphabetical listing) of referencing should be used in the body of the manuscript while only essential references must be cited and listed. Examples of citing references include: Omeiza (2012) or (Omeiza, 2012) as appropriate; Olaniyan and Oje (2002) or (Olaniyan and Oje, 2002) as appropriate; Ogunlela et al (2006) or (Ogunlela et al, 2006) as appropriate. Examples of listing references are as follows:

Open Access Agreement

Upon acceptance of an article, authors will be requested to download from our homepage the open access agreement form, complete and sign it, and then upload it to the portal against that particular submission.

Article Publication Charge

The Nigerian Journal of Technological Development (NJTD) is an open access journal. As a result, publishing of an article in the Journal requires an Article Publication Charge (APC), which will be billed following the acceptance of the article. Aside from this, the Journal does not impose any other charge on the author, be it submission charge or colour charge.

The APC will be charged based on the corresponding author’s affiliation. Where the corresponding author has a dual affiliation, the affiliation of where the work was carried out will be used. For the corresponding authors based in Nigeria, the APC of ₦25,000.00 (NGN) will be imposed while $100.00 (USD) will be imposed on corresponding authors outside Nigeria. The publication fee is non-refundable once the article is published online. Payment can be made by International Bank wire transfer, Western Union money transfer, MoneyGram, Online money transfer, or Payoneer.

Payment instructions will be sent to the corresponding author by the Managing Editor after the acceptance of the paper. The evidence of payment should be uploaded on the portal against the submission immediately after payment.

Subscription and Advertisement

The subscription and advertisement rates can be obtained from the Editor-in-Chief, the Managing Editor or the Business Manager. Current and past volumes of the journal are available at Room G11, Department of Materials and Metallurgical Engineering, Faculty of Engineering and Technology, University of Ilorin, Ilorin; at Options Bookshop, Ibadan; or Jasper Books Nig. Ltd, Ilorin, for sale at reduced price.

Complimentary Copies

Since authors can always download their published papers from our website at, on our homepage at AJOL and in the Scopus database, we no longer send the author’s complimentary copy to the authors. However, any author that so requires a print version of the journal shall pay a sum of Three Thousand Naira (N3,000:00) per copy exclusive of the delivery cost.


For technical support on submissions, please send an e-mail to the Managing Editor via or For questions about the editorial process especially on the status of manuscripts under review, authors may write to request for this information only when a three-month period from submission has elapsed.

Peer Review Process

NJTD operates a double anonymised peer review process. All submissions will be initially assessed by the Editor for suitability for the journal. Papers deemed technically suitable are then subjected to plagiarism check. If the similarity index is higher than 25%, such article is rejected at that stage and the corresponding author is communicated. Articles that pass this stage will be allocated to a Section Editor, who assigns a minimum of three reviewers to evaluate the scientific quality of the manuscript. However, the Editor is responsible for the final decision regarding acceptance or rejection of articles, and this decision is final.

Authors are encouraged to download the article processing flowchart from our homepage. The document summarises the peer review process used by NJTD. Authors should note that this process may last up to three months on the average.
