My research at the University of Nebraska-Lincoln focuses on developing innovative ion-conducting polymers essential for the next generation of hydrogen fuel cells. These materials are crucial for accelerating the adoption of clean energy, especially for heavy-duty vehicles like long-haul trucks, by enabling greater efficiency and range. My work directly addresses the need for durable, cost-effective, and high-performing materials in fuel cell membrane-electrode assemblies.
I specialize in the synthesis, modification, and comprehensive characterization of these critical polymers, with a proven track record in evaluating ionic conductivity across various temperature ranges to optimize performance. My extensive analytical toolkit includes spectroscopy (FTIR, NMR, HPLC, GC-MS, XPS, UV/Vis, XRD), chromatography & molecular weight (GPC, TLC), thermal analysis (DSC, DMA, TGA), surface & morphology (AFM, SEM, Ellipsometry), and colloidal & electrochemical techniques (DLS, Zeta-potential, EIS, QCM).
A significant portion of my research is dedicated to high-temperature Proton Exchange Membrane Fuel Cells (HT-PEMFCs), which operate efficiently at temperatures ranging from 100 to 220 °C. This offers substantial benefits for industrial applications, including faster electrochemical reactions, enhanced impurity tolerance, reduced catalyst poisoning, and simplified thermal management (eliminating the need for a humidifier). My goal is to engineer materials that facilitate efficient proton transport at elevated temperatures, ensuring robust chemical, mechanical, and thermal stability while remaining cost-effective.
Beyond PEMFCs, my background includes diverse polymer science projects:
• Photocuring of polymers via thiol-ene click reactions.
• Synthesis of nanostructured block copolymers for hydrophobic coatings using RAFT polymerization.
• Microencapsulation of Phase Change Materials (PCMs) for textile and drug delivery applications.
I also have experience in various Film Preparation techniques, including spin coating, Dip Coating, Solution Casting, and Doctor-Blade Coating. My programming language and software skills include C++, Python, Topspin, Zview, ChemDraw, and Origin.
This broad experience, coupled with practical insights from an internship at Indian Oil Corporation Limited (IOCL), equips me with a strong understanding of polymer material design, characterization, and industrial applications.
I am eager to discuss how my expertise in advanced polymer materials can contribute to the development of sustainable energy technologies within industry.
