• Exploring and synthesizing quantum spin liquid compounds and their behavior at high pressure (4.5 GPa).

• Designed and developed transition metal oxide surface-engineered catalysts for thermocatalytic downstream processes under the guidance of Prof. Sebastian C. Peter
• Prepared vanadium-dispersed titania (anatase) by the wet impregnation method at low pH, and tested for catalytic activity in a batch reactor at moderate temperatures (100-130 °C), using hydrogen peroxide as a selective oxidizer for methanol to formic acid conversion.
• Characterizations performed for V-dispersed TiO2 include XPS, SEM, TEM, and powder XRD, and to confirm the products of catalysis, 1H-NMR, and HPLC were used.

• Prepared A2SnBr6-type perovskites with different amines as A-site cations, such as methylene diamine, ethylamine, propylamine, 1,3-propanediamine, and 1,2-ethanediamine.
• Needle-like single crystals of (TMA)2NaInBr6 were prepared and observed very high quantum yield under UV light.
• Characterizations performed: Single Crystal XRD, temperature-dependent photoluminescence, FTIR, Raman spectroscopy, powder XRD, DRS-band gap determination, FESEM, XPS, and TGA-DSC.

• Synthesis of an extremely sterically shielding N-heterocyclic carbene ligand under the guidance of Prof. Priyabrata Ghana
• Targeted to prepare 1,3-bis[2,6-bis[bis-4-tert-butylphenyl)methyl]-4-methylphenyl]imidazol-2-ylidene complex, but only the first step was successful.
• From t-butylbenzene, I was able to prepare bis(4-tert-butylphenyl)methanol by Grignard reaction.
• 1H-NMR characterization was performed for the product.
