SEMINAR ON "NANOTECHNOLOGY AND ENERGY SAVING DEVICES"

A one-day seminar on the emerging topic “Nanotechnology and Energy Storage Devices” was successfully conducted today, featuring an enlightening lecture by Prof. P. Ravindran, a distinguished professor from the Central University of Thiruvarur. The seminar was organized with the objective of introducing participants to recent advancements in nanotechnology and its critical applications in the field of energy storage.

Prof. Ravindran, with his extensive research background and academic contributions in materials science, provided a comprehensive overview of the principles and potential of nanotechnology. He began the session by explaining the fundamentals of nanomaterials, their unique physicochemical properties, and how manipulating materials at the atomic and molecular level opens new possibilities in science and engineering.

A key highlight of the seminar was the detailed discussion on various energy storage devices, including lithium-ion batteries, solid-state batteries, supercapacitors, fuel cells, and hybrid energy storage systems. Prof. Ravindran elaborated on how nanotechnology is revolutionizing the design and performance of these devices. He illustrated the role of *nanostructured materials* such as graphene, carbon nanotubes, metal oxides, perovskites, and nanocomposites in enhancing energy density, charge/discharge rates, thermal stability, and overall efficiency.

Moreover, the seminar addressed challenges in the current energy storage technologies, such as material degradation, limited cycle life, and environmental concerns. Prof. Ravindran discussed ongoing research strategies to overcome these issues using nanomaterials and innovative fabrication techniques like sol-gel synthesis, chemical vapor deposition (CVD), and electrospinning.

The session also shed light on the global need for sustainable energy solutions and how nanotechnology could contribute significantly toward achieving clean energy goals and reducing carbon emissions. Real-world examples and case studies from ongoing national and international research projects were shared, enriching the learning experience of the audience.

An interactive Q&A session followed the lecture, where participants actively engaged with Prof. Ravindran, seeking clarifications and discussing research possibilities in this interdisciplinary domain.

In conclusion, the seminar proved to be a highly informative and inspiring event. It not only broadened the knowledge of the attendees but also encouraged them to explore the promising field of nanotechnology in energy science, with potential applications in electric vehicles, portable electronics, renewable energy systems, and more. The academic community expressed gratitude to Prof. P. Ravindran for his valuable insights and contributions Sandeep Krishnan .
