Dr. Rutuja U. Amate is a Research Assistant Professor in the School of Chemical Engineering at Yeungnam University, South Korea. Her research focuses on the synthesis and application of advanced nanostructured materials for electrochemical energy storage and electrochromic devices. She specializes in transition metal oxide nanostructures, heterostructure composites, and surfactant-assisted morphology control for high-performance asymmetric supercapacitors and multifunctional smart windows. Dr. Amate has successfully engineered several core–shell, heterostructure and bilayered composites, demonstrating enhanced areal capacitance, rate performance, and long-term stability in both three-electrode and pouch-type supercapacitor devices. Her work involves detailed characterization using XRD, FESEM, EIS, HR-TEM, Raman, XPS, and FTIR and she has published extensively in reputed international journals. She also contributes actively as a scientific reviewer and is involved in interdisciplinary collaborations across South Korea and India. Her editorial interests include nanomaterials, electrochemical devices, functional coatings, and sustainable energy technologies. Dr. Amate currently serves as a Guest Editor for the Special Issue “Advances in Polymer-Based Materials for Electrochemical Energy Storage” in Polymers (MDPI), where she aims to promote innovative research in emerging polymer-based and hybrid material systems for next-generation energy storage solutions.
