Yuan Yang, assistant professor of materials science and engineering, has developed a new method to increase the energy density of lithium (Li-ion) batteries. He has built a trilayer structure that is stable even in ambient air, which makes the battery both longer lasting and cheaper to manufacture. The work, which may improve the energy density of lithium batteries by 10-30%, is published online today in Nano Letters.
APAM Faculty and Research Scientists were honored at the SEAS 2016 Faculty Excellence Celebration. "We congratulate our colleagues on their outstanding research and scholarship, which have been rightly acknowledged by some of the world’s most prestigious institutions and organizations, as well as their excellence in teaching, recognized by Columbia University." - Dean Boyce
A team led by Nanfang Yu, assistant professor of applied physics, has discovered a new phase-transition optical material and demonstrated novel devices that dynamically control light over a much broader wavelength range and with larger modulation amplitude than what has currently been possible.
Six outstanding research efforts have been selected as finalists for this year's ACM Gordon Bell Prize in High Performance Computing. One of the finalists, titled “Extreme-Scale Phase Field Simulations of Coarsening Dynamics on the Sunway Taihulight Supercomputer,” involves the joint work of Qiang Du, the Fu Foundation Professor of Applied Mathematics in the APAM Department, along with his former postdoc (the lead author, currently a research scientist at the Chinese Academy of Sciences), his former student (currently a professor at the Univ. of South Carolina), and other collaborators in China.
Dan Bienstock, Mark Cane, Qiang Du, David Keyes, Kyle Mandli, and Chris Marianetti (co-chair) are part of the Data Science Institute’s newest working group —Frontiers in Computing Systems. The group will try to address some of the bottlenecks facing scientists working with massive data sets at Columbia and beyond. From astronomy and neuroscience, to civil engineering and genomics, major obstacles stand in the way of processing, analyzing and storing all this data.
