A team of Columbia Engineering researchers, led by Applied Physics Assistant Professor Nanfang Yu, has invented a method to control light propagating in confined pathways, or waveguides, with high efficiency by using nano-antennas.

Kam Leong, a versatile biomedical engineer originally trained in chemical engineering, has developed an impressive array of innovative nanotechnologies that have opened up new opportunities in biomedical research and drug delivery.

Nanoscientists have a new tool that promises to put long-lasting batteries and super-efficient solar panels within closer reach. Atomic Electron Tomography lets scientists precisely map the coordinates of individual atoms within a nanoparticle, or tiny cluster of a few hundred atoms.

Columbia scientists have demonstrated it is possible to manufacture solar cells that are far more efficient than existing silicon energy cells by using a new kind of material, a development that could help reduce fossil fuel consumption.

Thomas Theis has been named the inaugural executive director of the Columbia Nano Initiative, an interdisciplinary group led by Columbia Engineering focused on advancing research efforts in nanotechnology.
