It is with great pleasure that I present Volume 6 of the African Journal of Science, Technology and Engineering. This volume marks another significant step forward in our mission to foster innovative research and knowledge dissemination across the African continent and beyond.

This edition features a rich collection of peer-reviewed articles addressing current and emerging issues in various fields—ranging from emerging technologies, sustainable infrastructure, and advanced materials, to data-driven innovations and engineering applications tailored to local and global needs. The diversity and depth of contributions reflect the growing capacity and commitment of African scholars and practitioners in addressing complex scientific and technological challenges through locally relevant and globally informed solutions.

As Africa continues to assert its place in the global knowledge economy, it is vital that platforms like this journal provide visibility and support for homegrown research and innovations. Volume 6 not only celebrates intellectual achievement but also encourages collaboration, cross-disciplinary engagement, and practical application of science and technology to improve lives.

I commend the authors, reviewers, editorial board, and supporting institutions whose dedication and scholarly rigor have made realization of this volume possible. May this edition inspire further inquiry, innovation, and impactful solutions throughout Africa and the global scientific community.
