Shirish H. Sonawane is a scientist with interests in Chemical engineering, Wastewater Treatment, Nanomaterials, Nanotechnology, Encapsulation, and Nanocomposite. He vastly used acoustic and hydrodynamic cavitation technologies for the degradation of various pollutants. Also used ultrasound technology to synthesize, and modify nanomaterials to exploit them as catalysts. He also used ultrasound technology to synthesize sol which is applied on membranes to enhance the surface properties of the membranes. He also has proficiency in other research areas.His other popular works are Ultrasound assisted preparation of rGO/TiO2 nanocomposite for effective photocatalytic degradation of methylene blue under sunlight, investigation on the thermal conductivity and convective heat transfer enhancement in helical coiled heat exchanger using ultrasonically prepared rGO–TiO2nanocomposite-based nanofluids, and a review on Graphene Derivatives-Based Nanofluids: Investigation on Properties and Heat Transfer Characteristics. He also works in the field of Nuclear chemistry, focusing on Raman spectroscopy and, on occasion, Nanocomposites. His research in Polyaniline intersects with topics in Fourier transform infrared spectroscopy, Composite number, Platinum, and Proton exchange membrane fuel cell. Currently, he is also developing continuous mode of nanomaterial synthesis using microreactors using process intensification methodologies.
