Recent developments in materials science and nanotechnology have propelled the development of a plethora of materials with unique chemical and physical properties for various applications. Graphitic nanomaterials such as carbon nanotubes, fullerenes and, more recently, graphene oxide (GO)/reduced graphene oxide (rGO) and carbon quantum dots, have gained a great deal of interest for their potential applications in various aspects of science and technology. Graphene, the name specified to a one atom-thick two-dimensional (2D) single layer of sp2 hybridized carbon atoms arranged in a honeycombed lattice with large surface area, exceptional thermal, mechanical, optical and structural properties. This wonder material is a “hot topic” of research in interdisciplinary sciences with potential applications in several fields such as nanoelectronics, organic catalysis, environmental remediation, drug delivery, etc. The last decade has also witnessed a huge interest in the synthesis of carbon quantum dots (CQDs) and their applications in various fields due to their ease of synthesis and functionalization, their outstanding properties such as size- and wavelength-dependent luminescence emission, resistance to photobleaching and good biocompatibility. Due to their low cost of production, large specific surface area and abundant surface chemistry, rGO and CQDs have shown great promise in the development of novel composites, biosensors, photocatalysts, electrocatalysts, and drug delivery systems. These hybrid nanomaterials offer unusual combinations of electrical, thermal, mechanical, catalytic, electrocatalytic, optical and magnetic performances that are difficult to attain separately from the individual components. In this presentation, I will focus on the different strategies for the preparation of rGO- and CQDsbased hybrid materials and the various applications of these nanohybrids in energy, biomedicine, and environmental remediation. Dr. Rabah Boukherroub received a PhD in chemistry from the University Paul Sabatier in Toulouse, France. He is currently a CNRS research director and a group leader at the Institute of Electronics, Microelectronics and Nanotechnology (IEMN), University of Lille, France. He is Associate Editor for ACS Applied Materials & Interfaces. He is also a guest Professor, China University of Petroleum, Qingdao, China. His research interests are in the area of nanostructured functional materials, surface chemistry, and photophysics of semiconductor/metal nanostructures with emphasis on biosensors, nanomedicine, photocatalysis and energy-related applications. He is a co-author of 440+ research publications and wrote 31 book chapters in subjects related to nanotechnology, materials chemistry, and biosensors. He has 11 patents or patents pending.

All are cordially invited to attend.
