Dr. Mayank Pandey completed his Ph.D. in materials science from VIT University, Vellore, India, on the topic “Preparation and characterization of polymer electrolyte for electrochemical device applications. He then went on to complete his postdoctoral studies in electrical and thermal degradation of graphene-based polymer composite for electronic device applications from CHRIST (Deemed To Be University) Bangalore, India. He is an experienced material physicist with an experimental background in synthesizing graphene quantum dot- (GQDs) based polymer nanocomposites. His research areas also include fabrication of polymer blends and composite electrolytes, organic semiconductor/organic solar cells, and their impedance spectroscopy analysis. Besides investigating the structural, optical, and electronic properties of GQDs based materials, he has also contributed towards the development of new approaches in the field of nanocarbon derivatives. Kalim Deshmukh is a Senior Researcher at the New Technologies-Research Centre, University of West Bohemia, Pilsen, Czech Republic. He has over 20 years of research experience working with various nanostructured materials, and polymeric materials, especially polymer blends, and nanocomposites for numerous applications. His research interest is mainly focused on the synthesis, characterization, and evaluation of the structure–property relationships of different polymers reinforced with various nanofillers including metal and metal oxide nanoparticles, carbon allotropes, and novel 2D nanomaterials for energy storage, gas sensing and EMI shielding applications. Dr. Chaudhery Mustansar Hussain, PhD, is an Adjunct Professor and Director of Laboratories in the Department of Chemistry & Environmental Sciences at the New Jersey Institute of Technology (NJIT), Newark, New Jersey, United States. His research is focused on the applications of nanotechnology and advanced materials, environmental management, analytical chemistry, and other various industries. Dr. Hussain is the author of numerous papers in peer-reviewed journals as well as a prolific author and editor of around One hundred and fifty (150) books, including scientific monographs and handbooks in his research areas. He has published with ELSEVIER, American Chemical Society, Royal Society of Chemistry, John Wiley & Sons, CRC Press, and Springer.
