Table of contents

A notable mention - All these incredible research and development articles in this edition are from STEM students at the University of Plymouth, working on their final year research project during the COVID19 lockdowns of 2020 and 2021. A huge thank you to them, and their committed supervisors in STEM. I have enjoyed reading your submissions and working with you all. Not only have you navigated nimbly the COVID19 restrictions, but also tackled the conversion and review process to produce these excellent papers! I very much hope that the experience of being "published" takes you to greater heights in your future careers. Feel free to share your success and cite your work. With kind regards, Dr Jason B. Truscott (Chief Editor).
