Speech Title: Greener and Energy-Efficient Cavitation Assisted Process Intensification for the Generation of Nanomaterials

Abstract: Much effort is currently being devoted to studying nanomaterials, mainly due to their wide variety of applications. Particularly, nanoparticles have generated a large research effort because their properties differ markedly from those of their bulk counterparts. Many different approaches have been applied to the fabrication of nano-entity, such as co-precipitation, microemulsion, supercritical sol-gel processing, hydrothermal synthesis, or high energy ball milling. Directed to the problems of these conventional methods, new synthetic methods have received increased attention in recent years. Cavitation, an approach for synthesizing various compounds at milder conditions, is already the rage in materials engineering. The major advantage of this new method is that it affords a reliable and facile route for controlling both the synthetic process and nanostructure in advanced materials. Also, this process provides chemical homogeneity and reactivity through atomic-level mixing within the precursor system, and phase pure crystalline materials can be prepared by annealing at reduced temperatures. Various nanomaterials and nanodispersions have been generated using this technique to develop biosensors and other applications. More importantly, novel carbon materials such as Graphene and Fullerene have been exploited for the functionalization and in the development of nanocomposites to be employed in the sensors.
