Dr. Sonalika Vaidya

Assistant Professor (Scientist-D)

Our group is working in two areas. In one, we are focused on designing anisotropic, core-shell, self-assembled nanostructures with ideal and controllable morphology, size, and structure and formation of their oriented assemblies. The nanostructures designed are studied for their photocatalytic and electrocatalytic applications.  Our other interest focuses on studying nucleation and growth of nanostructures using SAXS.

CONTACT INFORMATION :

Research Interest

  • Design of anisotropic, core-shell and self-assembled nanostructures with ideal and controllable morphology, size, and structure and improved performance for solving persistent issues related to energy and environment.
  • Oriented/ ordered assemblies of nanostructures are formed on solid substrates. The effect of orientation and ordering are studied on their opto-electronic properties and catalytic behavior.
  • Small Angle X-ray scattering is used to study the nucleation and growth of nanostructures. In this aspect, we are currently trying to understand the effect of various parameters that are involved in the formation of microemulsions on size and shape of microemulsions. 

Research Highlights

  • Dr. Sonalika Vaidya's group is involved in understanding the formation of nanostructures using SAXS. Recently in this aspect, we have studied the effect of variation of co-surfactant on the growth of copper oxalates synthesized using microemulsions. More details of this research can be found in Phys.Chem.Chem.Phys., 2019, 21, 336.
