For the first time, scientists can distinguish the proportion of bromoform molecules that directly break bonds (dissociate) vs. those that rearrange (isomerize). This is an important step toward understanding the formation of bromoform isomers, which had long been predicted but had not been fully experimentally confirmed. Bromoform molecules are important in part for their role in ozone degradation in the Earth’s atmosphere. 

In this week’s Physics of Fluids, researchers employ machine learning to more accurately model the boundary layer wind field of tropical cyclones. Conventional approaches to storm forecasting involve large numerical simulations run on supercomputers incorporating mountains of observational data, and they still often result in inaccurate or incomplete predictions. In contrast, the author’s machine learning algorithm is equipped with atmospheric physics equations that can produce more accurate results faster and with less data.

In this week’s Physics of Fluids, researchers study how Champatis roll and bounce down inclines. The authors released a heap of the seeds down an inclined plane while a camera recorded their descent to analyze their speed and the dynamics of their movement. The grains start to spread out slowly, then decrease quickly as they move downstream, akin to rock avalanches. This research may provide valuable insights into geological flows, including hyperspreading of rock avalanches, and could contribute to resolving challenges in this area.

Case Western Reserve University President Eric W. Kaler and Provost Joy K. Ward announced today that David Gerdes, a renowned physics scholar and department chair from University of Michigan, will become dean of the College of Arts and Sciences on March 1.

A team of researchers from Jilin University, NYU Abu Dhabi’s Smart Materials Lab, and the Center for Smart Engineering Materials, led by Professor of Chemistry Pance Naumov, has developed a new crystalline material that can harvest water from fog without any energy input. The design of the novel type of smart crystals, which the researchers named Janus crystals, is inspired by desert plants and animals, which can survive in arid conditions.
