Nanostructures are a stunning array of intricate patterns that are imperceptible to the human eye, yet they help power modern life. They are the building blocks of microchip transistors, etched onto grating substrates of space-based X-ray telescopes, and drive innovations in medicine, sustainability, and quantum computing.Since the 1970s, Henry “Hank” Smith, MIT professor emeritus of electrical engineering, has been a leading force in this field. He pioneered the use of proximity X-ray lithography, proving that X-rays’ short optical wavelength could produce high-resolution patterns at the nanometer scale. Smith also made…
