Scientists expect climate change to increase America’s propensity for warm moist air, which should mean more thunderstorms and tornadoes. Wind speeds should stay the same, but tornado patterns are too small to explore deeply in the global computer models meant to simulate huge sections of the planet. “There’s a lot of interest nowadays in how climate change is going to affect aspects of weather, especially extreme weather — whether it’s droughts, heat waves, floods or hurricanes,” said Prof. Michael Tippett, adding that if you had to rank where the scientific research is certain or uncertain, tornadoes sit at the top of the uncertainty list.

Research from Latha Venaktaraman's group was recently published in the artcile, "Non-chemisorbed gold–sulfur binding prevails in self-assembled monolayers," in Nature Chemistry. Improved mechanistic understanding will help answer the question of how predominantly chemisorbed sulfur-gold SAMs can be reliably formed under ambient conditions, if at all. This will help focus efforts to identify new linker groups, and/or preparation methods, that facilitate the construction of more stable SAMs with increased electronic transparency and stability. The effect of surface pre-treatments on the molecule-substrate bonding of gold-thiol SAMs is likely also a rich area of further study/reinterpretation.
Simon Billinge, a Professor of Materials Science and Engineering and Applied Physics and Applied Mathematics and a Scientist at Brookhaven National Laboratory, and APAM alumn, Dr. Chenyang Shi (Ph.D. 2015, Materials Science and Engineering), were recently featured in the following article by Mary Alexandra Agner. It was originally published as highlight on the Advanced Photon Source/Argonne National Laboratory website.
I. Cevdet Noyan, Professor of Materials Science and Engineering and of Earth and Environmental Engineering and former Chair of the APAM Department, has won the 2019 Hanawalt Award from the International Centre for Diffraction Data (ICDD). He was selected for this honor for his many contributions to X-ray diffraction methods and for the depth and breadth of knowledge in combining materials science and diffraction characterization.
Professor Michal Lipson will receive the 2019 Comstock Prize in Physics. Lipson’s pioneering research established the groundwork for silicon photonics, a growing field in which she remains a pioneer and leader. The technology, which uses optical rays to transfer data among computer chips, is now considered to be one of the most promising directions for solving major bottlenecks in microelectronics.
