Our unwavering dedication to innovation, cutting-edge research, and the development of practical solutions serves as the driving force behind our work.
​
Dr. Ravi's group has consistently remained at the forefront of pioneering technological advancements in these domains:
​
Additive Manufacturing: We have engineered a state-of-the-art indigenous Direct Energy Deposition-based metal additive manufacturing machine. This groundbreaking innovation excels in fabricating intricate 3D structures and components, as well as in repairing and enhancing existing ones. Our ongoing research endeavors aim to transform conventional metal 3D printing machines into "smart metal 3D printers." This ambitious endeavor involves establishing essential infrastructure, assembling a dedicated team of experts, and harnessing cutting-edge technologies to actively participate in this transformative phase. Central to our research initiatives is a robust emphasis on In-situ Monitoring for Metal Additive Manufacturing (AM) Processes. We firmly believe that real-time monitoring and control are pivotal for pushing the boundaries of what Metal AM can achieve.
​
Computational Thermodynamic Modeling (CALPHAD Approach): Our group specializes in Computational Thermodynamic modeling, utilizing the CALPHAD approach. We employ this specialized expertise to design novel thixoformable Al and Mg alloys. Furthermore, we actively explore the synergistic integration of CALPHAD calculations, Data Science, and in-situ monitoring processes to metamorphose metal AM machines into "Smart metal AM machines."
​
Self-cleaning Coatings: Our innovative approach transcends the realm of manufacturing. We have successfully developed cutting-edge coating technology tailored for easy and self-cleaning of solar panel surfaces. These coatings possess pivotal attributes such as transparency, scalability, durability, and superhydrophobic properties. They effectively mitigate dust accumulation on solar panels and require minimal water for self-cleaning. Moreover, our technology seamlessly integrates into solar panel manufacturing processes.
​
Expanding the horizons of self-cleaning coatings, we have adapted this technology for biomedical applications. Our self-cleaning and anti-fogging coatings find utility in various biomedical settings, ensuring clarity and cleanliness. Our commitment to innovation knows no bounds. We have engineered an exceptionally high-temperature stable coating with outstanding mechanical and environmental durability. This self-cleaning coating is meticulously crafted to thrive in extreme environments, offering groundbreaking solutions for demanding engineering applications.
