Program Description:
Understanding interfacial phenomena is important in processes like corrosion, catalysis, and electrochemical reactions. Specifically, in corrosion inhibition, the assembly of adsorbed surfactants at metal-water interfaces in well-packed, ordered layers is desired. The interfacial regions are frequently the active site of the chemical reaction and dominate the entire system. Molecular level understanding of such interfaces are hampered due to the lack of surface specific techniques. I have employed surface-specific second order nonlinear optical technique sum frequency generation (SFG) vibrational spectroscopy to probe the in-situ adsorption and self-assembly of cationic surfactants at air-liquid and liquid-metal interfaces.

I was born in a country known as the land of rivers, Bangladesh (Southeast Asia), in 1991 and raised in a beautiful village with a large group of family members. Besides research, I like to play cricket, eating out, short trips, spending time with family and friends. Currently, I am working on the project of adsorption and self-assembly of surfactants at air-liquid and liquid-solid interfaces by using sum frequency generation (SFG) spectroscopy in the Cimatu research group at Ohio University.
