FEATURED STORY

Columbia has been at the forefront of nanoscience research for more than 15 years, and, with the University’s launch of the Columbia Nano Initiative (CNI), activity on this front is accelerating. As James T. Yardley, CNI’s acting executive director, puts it, “When I came here in 2000 and walked up and down the hallways, you’d hardly see anybody. But now when you walk up and down the halls, you see people arguing with each other, holding samples, animated in discussion.”

Working with colleagues Keren Bergman, James Hone, Colin Nuckolls, Ken Shepard, Latha Venkataraman, and many others, Yardley has been instrumental in leading nanoscience at Columbia, and he sees this burgeoning field bringing together investigators in an exciting new way.

“At Columbia, we’ve really pioneered the concept of interdisciplinary research, of getting more than the sum of the parts by bringing together physicists, engineers, and chemists to do collaborative research,” he says. “We’ve revolutionized the fundamental understanding of how electrons move through molecules; of what graphene, a material we pioneered here, is and how it works; and established basic knowledge about carbon nanotubes. Our discoveries have fostered important research around the world, and that’s really come about because of the collaborative environment we’ve created here at Columbia.”

The complexities of nanoscience, manipulating individual atoms and molecules, make for a perfect intersection of disciplines. The rules change at the nanoscale; materials, electrons, chemicals—all behave differently. Shared equipment, such as the state-of-the-art transmission electron microscope, and expanded facilities like the Nanofabrication Clean Room, which is almost doubling in size, are reinforcing partnerships, as is Columbia’s new $15 million, multiyear NSF Materials Research Science and Engineering Center (MRSEC).

Here, Columbia Engineering spotlights just a few of our professors whose work is advancing the field of nanoscience and, in many ways, pushing boundaries far beyond the nanoscale.
