A team, lead by Simon Billinge, has discovered an unusual form of electronic order in a new family of unconventional superconductors. The finding, described in Nature Communications, establishes an unexpected connection between this new group of titanium-oxypnictide superconductors and the more familiar cuprates and iron-pnictides, providing scientists with a new family of materials from which they can gain deeper insights into the mysteries of high-temperature superconductivity.
Five APAM faculty members (Chris Marianetti, Michael Mauel, Adam Sobel, Latha Venkataraman, and Chris Wiggins), made presentations during the SEAS 150th Anniversary Symposium on Friday, November 14, from 2:00-4:00 PM, in Roone Arledge Auditorium in Lerner Hall.

Prof. Chris Marianetti and Ph.D. candidate, Eric Isaacs, were recently featured in the article, "Supercomputers Reveal Strange, Stress-Induced Transformations in World's Thinnest Materials:Columbia researchers used Brookhaven Lab supercomputer simulations to map and compare the transformations and breaking points of graphene and other promising monolayers," by Justin Eure.
Just as a watchmaker is enamored with the beauty of the miniature cogs and wheels that make a timepiece work, Simon Billinge, professor of materials science and of applied physics and applied mathematics, is equally enraptured by the minuscule world of nanoparticles. By learning how these ultrafine particles between 1 and 100 nanometers in size behave within nanomaterials measured in billionths of a meter, Billinge hopes to optimize their performance and utility in biomedical, optical, and electronic applications.
