**About the Special Issue Editors**

**Diganta B. Das** is an Associate Professor in the Department of Chemical Engineering at Loughborough University, UK. His research involves the application of principles of fluid flow and mass transport behaviour in porous media (both biological and non-biological) to solve bioengineering and water engineering problems. He currently serves as the editor of *Water Science and Technology* and *Water Supply* (IWA Publishers), and is an Editorial Board member of *Biotechnology Letters* (Springer-Verlag), *Pharmaceutics* (MDPI) and *Clean Technologies* (MDPI), besides being associated with a number of other journals. Prior to his current appointment, Dr. Das was a Lecturer (Assistant Professor) at the University of Oxford, UK, a postdoctoral research fellow at Delft University of Technology in the Netherlands, and a visiting fellow at Princeton University. He has also held visiting appointments at Eindhoven University, Netherlands, Texas Southern University, USA, and Selcuk University, Turkey. Dr. Das has published more than 100 peer-reviewed journal articles, more than 40 proceedings of international conferences and edited books, co-edited 2 scientific books and co-authored 3 books.

**Mostafa Mabrouk** is an Associate Professor in the Department of Refractories, Ceramics and Building Materials at the National Research Centre (NRC), Egypt. His research involves the synthesis and characterisation of various forms of bioactive materials such as bioactive glass, ceramics, and their polymer composites. The final delivered form of the biomaterials was one of the most important discoveries of Dr. Mabrouk as he was able to deliver different types of biomaterials through carriers including nanomaterials, scaffolds, microspheres and membranes. Dr. Mabrouk has been an Academic Visitor at Loughborough University, UK. He also spent two years as a postdoctoral fellow in the WADDP research group at Witwatersrand University, South Africa. He go<sup>t</sup> his Ph.D. in Chemistry from the Biomaterials Group at Rennes 1 University, France. His current research is devoted to the preparation of different porous inorganic carriers and 3D scaffold for the tissue engineering field.

**Hanan Beherei** is currently a Professor of the Biomedical Materials and Regenerative Medicine group in the Ceramics Department at the National Research Centre, Egypt. Prof. Beherei's research focuses on the design and development of new types of nanomaterials using a number of advanced technologies and evaluating their use in biotechnological and biomedical applications, including the development of novel systems for effective drug delivery, tissue engineering, and renewable medicine in vitro and in vivo. She prepared and characterised new biomaterials based on bioactive glasses with electrospinning assisted methods developed for the fabrication of biomedical nanostructures. She also designed specific nanomaterials being considered in current research projects on bone, nerve, skin and cardiac tissue through local projects in Egypt. She has worked in close collaboration with a number of researchers and academics with expertise in cell biology, biochemistry, biotechnology, and medical sciences in Japan and in the UK. She has designed, prepared and characterised many novel biocompatible ceramic composite-based hydroxyapatites and others calcium phosphates with metal oxides like TiO2, ZrO2, Al2O3, MgO, and ZnO, as well as calcium aluminate and calcium silicate for use in bone grafts. She designed, prepared and characterised many glass systems by melting and sol gel methods for use as bone grafts. She was a postdoctoral fellow in the Tissue Engineering Department of GBF, Braunschweig Germany. She was also a Lecturer (Associate Professor) at Taif University, KSA from 2008 to 2009 and a Lecturer (Professor) at Taif University, KSA from 2010 to 2015.

**Arthanareeswaran Gangasalam** is a Professor in the Department of Chemical Engineering at the National Institute of Technology, Tiruchirappalli, India. His current research involves improving the performance of polymer membranes by mixing with nanomaterials for ultrafiltration, nanofiltration, gas separation, and membrane distillation applications. The prime novelty of this work is the selection of organic and inorganic membrane materials for membrane fabrication, as well as to achieve high permeability and anti-fouling properties with rejection of molecules. He is the lead investigator of various funded projects from DST-India, DBT-India. CNPq-Brazil, MST-Korea, RAE-UK, AISTDF-India, and NRDI-Hungary. Arthanareeswaran received a Research Exchange Award from RAE-UK, an Endeavour Executive Award from the Australian Government and a Brainpool Award from the South Korean Government. Hiyoshi Corporation, Japan awarded him the Hiyoshi Environmental Award for outstanding research in the field of environmental conservation. Dr. Arthanareeswaran was an academic visitor of the University of Sao Paulo, Brazil, Monash University, Australia, Loughborough University, UK, Universiti Teknologi Malaysia, Malaysia, Konkuk University, South Korea, University of Szeged, Hungary, and Prince of Songkla University, Thailand. He served as a Guest Editor for the journals *Desalination*, *Environmental and Ecological Safety*, and *Desalination and Water Treatment*. Arthanareeswaran has authored over 110 original articles in peerreviewed international journals, more than 45 papers in the proceedings of international conferences, two scientific books, and seven book chapters.
