Graphene gets bright: World's thinnest lightbulb developed

Led by Young Duck Kim, a postdoctoral research scientist in James Hone's group at Columbia Engineering, a team of scientists from Columbia, Seoul National University (SNU), and Korea Research Institute of Standards and Science ...

Researchers first to create a single-molecule diode

Under the direction of Latha Venkataraman, associate professor of applied physics at Columbia Engineering, researchers have designed a new technique to create a single-molecule diode, and, in doing so, they have developed ...

Two-dimensional semiconductor comes clean

In 2013 James Hone, Wang Fong-Jen Professor of Mechanical Engineering at Columbia Engineering, and colleagues at Columbia demonstrated that they could dramatically improve the performance of graphene—highly conducting two-dimensional ...

Engineering team invents a camera that powers itself

A research team led by Shree K. Nayar, T.C. Chang Professor of Computer Science at Columbia Engineering, has invented a prototype video camera that is the first to be fully self-powered—it can produce an image each second, ...

New high-speed 3-D microscope gives deeper view of living things

Opening new doors for biomedical and neuroscience research, Elizabeth Hillman, associate professor of biomedical engineering at Columbia Engineering and of radiology at Columbia University Medical Center (CUMC), has developed ...

Revolutionary ultra-thin 'meta-lens' enables full-color imaging

Light of different colors travels at different speeds in different materials and structures. This is why we see white light split into its constituent colors after refracting through a prism, a phenomenon called dispersion. ...

Machine learning may be a game-changer for climate prediction

A major challenge in current climate prediction models is how to accurately represent clouds and their atmospheric heating and moistening. This challenge is behind the wide spread in climate prediction. Yet accurate predictions ...
