SPECIAL ISSUE

SciEnggJ is committed to fostering high-quality research and scholarly discourse in the fields of science and engineering. To achieve this goal, we invite proposals for special issues that delve into specific themes or topics of significance within our domain. When submitting a proposal for a special issue, it is important to clearly define the scope and rationale behind the proposed theme. We encourage guest editors with expertise in the relevant area to spearhead these initiatives, ensuring that the special issue maintains the rigorous standards and academic integrity associated with SciEnggJ.

The proposal should outline a tentative timeline for the special issue, including key milestones such as submission deadlines, review periods, and the expected publication date. Additionally, identifying potential contributors who can provide high-quality submissions within the theme of the special issue is crucial for its success. Once the proposal is accepted, the guest editor(s) will collaborate with our editorial team to craft a compelling call for papers. This call should articulate the theme, objectives, and focus areas of the special issue, aligning with the journal's scope and interests.

Submission guidelines should be provided to authors, detailing manuscript formatting instructions, word limits, referencing styles, and any other specific requirements. A transparent peer review process is essential to ensure the quality and originality of submissions. Authors should be kept informed about the status of their submissions throughout the review process, receiving timely updates and feedback. Once accepted, authors will be guided through the final manuscript preparation process, including formatting and copyright requirements.

To maximize the impact and visibility of the special issue, we will employ various marketing strategies, including promotion through our website, social media platforms, mailing lists, and academic networks. Additionally, we will ensure that the special issue is indexed in relevant databases and archives for maximum discoverability and long-term preservation. Ethical considerations, such as plagiarism detection and conflict of interest disclosures, will be strictly enforced throughout the publication process.

After publication, we will monitor feedback and metrics to evaluate the impact and reach of the special issue. This feedback will inform continuous improvements to our processes and help shape future special issues. Ultimately, our goal is to facilitate the dissemination of cutting-edge research and promote scholarly dialogue within the fields of science and engineering through our special issue initiatives.
