Marking the 138th birth anniversary of Professor C. V. Raman, the illustrious Indian Nobel Laureate and founder of the Raman Research Institute (RRI), the Institute came alive today with the Founder’s Day lecture 2026 in its auditorium.
Professor Tarun Souradeep, Director, RRI, welcomed the guests to the lecture. Ranjini Bandyopadhyay, a senior professor at the Institute, set the stage by introducing the distinguished speaker, Prof. Umesh Waghmare, Secretary, Department of Science and Technology (DST), Government of India, to the esteemed audience.
Prof. Umesh Waghmare delivered this year’s address on ‘Metavalent Bonds: Crystals in Love with Instabilities’. He commenced his address by reflecting on his experience spent as a summer research student at the Raman Research Institute in 1989, noting that the two months here significantly influenced his decision to pursue his career in India.
Prof. Waghmare opened his lecture with a captivating explanation of the Raman Effect, revealing how scientists harness light to unlock the secrets of the bonds that hold materials together. He then introduced metavalent bonding, a unique form of bonding that gives certain materials unusual properties and the ability to undergo changes in their structure and behaviour.
He concluded by highlighting how understanding these materials not only offer insights into fundamental physics but could also open up possibilities for future technological applications. The talk, a highlight event on RRI’s calendar, was also live-streamed on RRI’s official YouTube channel.
