Ravikant Upadhyay, a research scholar at the Department of Chemistry, School of Natural Sciences (SoNS) and guided by Dr. Susanta Sinha Roy, Associate Professor, Department of Physics, became the first Ph.D. scholar from Shiv Nadar University and successfully defended his thesis in public viva-voce.
 
Ravikant’s research is titled, “Novel Wet Chemical Methods for the Synthesis of Nanomaterials and their application water treatment”, that describes novel wet chemical methods suitable for the preparation of nanomaterials of both inorganic (metals and metal oxides) and carbonic (graphene) materials. The research also demonstrated the successful implementation of the synthesized nanomaterials in the detection and removal of waterborne pollutants.
Novel oil impregnated gelatinous surfactant self-assemblies based syntheses were designed for the constrained growth of metals nanoparticles. By exploring strict spatial confinement offered by the rigid surfactant (namely CTAB and Tween 80) gels, a controlled growth of Au and Ag nanoparticles, with a myriad of exotic shapes, were achieved. Attempts were made to utilize all the synthesized metal nanoparticles for detection and removal of the waterborne pollutants. Besides acting as templates for the growth of metals nanoparticles, metals containing surfactant gels also served efficiently as metal precursors for the preparation of metal oxides (ZnO, CuO, and ZrO2) nanoparticles. The results thus established surfactant gel method as a valid and efficient alternative for the conventional sol-gel method. Thus, the current study presented several novel synthesis methodologies for the fabrication of nanomaterials and also encompassed sufficient empirical evidence to decipher the role of different reaction parameters in deciding the physicochemical properties of nanomaterials; also highlighting various possible uses of nanomaterials in accomplishing the goal of water treatment.
