For nearly 60 years, scientists have been trying to determine how manganese oxide (MnO) achieves its long-range magnetic order of alternating up and down electron spins. Simon Billinge and Benjamin Frandsen used their recently developed mathematical approach to study the short-range magnetic interactions that they believe drive this long-range order. The research was described in a paper published on May 11 in Physical Review Letters. Photo credit: Columbia Engineering/Timothy Lee Photographers.
Prof. Nanfang Yu, assistant professor of applied physics, has won a 2016 Young Investigator Award from the U.S. Office of Naval Research for exceptionally creative research with far-reaching implications for technological needs of the Navy and the Department of Defense. For his proposal, “Phase-Change Correlated Perovskites as a New Platform for Photonics,” he is slated to receive approximately $510,000 over a three year period for equipment, graduate student stipends and scholarships, and other expenses to sustain his research.
High-performance energy storage devices will be key to a sustainable future, allowing cell phones to go longer between recharging, increasing mileage for electric vehicles, and stabilizing the power output of solar and wind energy. “Advanced batteries will be a game changer for addressing global challenges of energy sustainability and environmental stewardship,” says Yuan Yang, assistant professor of materials science and engineering. “Now is a really exciting time to work in batteries and energy storage.”
Earth’s climate is constantly changing. With this change comes an increased frequency of extreme and potentially devastating events like floods, droughts, and storms, which impact populations around the globe. Mark Cane, Michael Tippett, and Lorenzo Polvani are working to shed light on what leads to climate variability, how humans play a role, and how we are all affected. Their research is an important part of worldwide efforts to better predict and prepare for the consequences of climate change.
Sometimes, taking an approach that is opposite to conventional practice can lead to breakthrough science. That’s the case in a research partnership between Pierre Gentine and Adam Sobel. The two have collaborated to develop a new simulation strategy that more accurately models Amazon seasonal cycles. This simulation strategy gives deeper insight into the water and carbon cycles of the Amazon rain forest and better understanding of tropical climates overall.
