Q. Which institution recently collaborated with Columbia University to develop optical driving process for nanopatterns?
Answer: IIT Guwahati
Notes: Scientists from IIT Guwahati and Columbia University have developed a novel nanopatterning method using a tabletop IR laser. Led by Dr. Rishi Maiti from IIT Guwahati, the research was published in Science Advances. Nanopatterning, crucial for creating nano-scaled optical elements, significantly impacts advanced light detectors, solar cells, lasers, and LEDs. The technique manipulates materials at scales 100,000 times smaller than a human hair's width.
