PNNL and partners have received renewed funding from the U.S. Department of Energy for a center designed to explore science that supports technologies such as solar energy and fuel cells. PNNL—in collaboration with Yale University, the University of Wisconsin, Massachusetts Institute of Technology, the University of Washington, and Purdue University—earned the renewal through significant achievements in developing catalysts that can convert between electrical and chemical energy. #electrocatalyst #fuelcells #solarenergy https://buff.ly/2Lq50uh

Hurricanes that intensify rapidly - a characteristic of almost all powerful hurricanes - do so more strongly and quickly now than they did 30 years ago.
New study published today in Geophysical Research Letters, a journal of the American Geophysical Union, explores why.

"The mechanisms of our planet are very complex," said Dr. L. Ruby Leung. "We want to represent how interactions of atmosphere, oceans, land, and ice govern the behavior of Earth as a system and predict future changes in water supply, extreme events, and coastal vulnerability. With this information, we can inform decisions to help strengthen the resilience of populations, our economy, energy resources, and national security."

We had the pleasure of listening to Dr. Art McDonald, winner of the 2015 Nobel Prize in Physics and Professor Emeritus from Queen’s University in Canada, give a lecture on “Neutrinos, Dark Matter and the Nature of the Universe” yesterday. What a privilege! #nobelprize #physics

Currently, industry uses a common but expensive process called cryogenic distillation to separate xenon from other gases or the atmosphere. In that costly process, a lot of energy is used to chill entire gas streams down to far below freezing in order to concentrate the xenon.

"The process we've demonstrated to selectively trap xenon in a MOF can be done at room temperature," said Praveen Thallapally a materials scientist at PNNL and a corresponding author on the paper. "You pass a mixed gas stream over the MOF materials just one time to capture the xenon and it can be stored long term and easily released for industrial applications when you want to use it."

Researchers at PNNL, in collaboration with other research groups, optimized the properties of a MOF material called SBMOF-1 and demonstrated that it selectively traps xenon and, in a second pass, can also trap krypton, both of which are byproducts of nuclear reprocessing. Much of this research is funded by DOE's Office of Nuclear Energy to explore technologies that may one day enable safe, efficient recycling of nuclear fuel. https://buff.ly/2BFmLjF

With some back-of-the-envelope calculations, Eric Wiedner and his colleagues at #PNNL predicted that a cobalt catalyst could take a different reaction path to work in water with inexpensive sodium bicarbonate (baking soda). The result? It’s the best-performing nonprecious metal catalyst for converting carbon dioxide in water. Learn more at https://goo.gl/5uPWMC.

A new study, published today in Science, capitalized on data from an area of the Amazon that is pristine except for the region around Manaus, the largest city in the Amazon, with a population of more than 2 million people. The setting gave scientists the rare opportunity to look at the impact of pollution on atmospheric processes in a largely pre-industrial environment and pinpoint the effects of the particles apart from other factors such as temperature and humidity.
In this study, scientists studied the role of ultrafine particles less than 50 nanometers wide in the development of thunderstorms. Similar but larger particles are known to play a role in feeding powerful, fast-moving updrafts of air from the land surface to the atmosphere, creating the clouds that play a central role in the formation of water droplets that fall as rain.
But scientists had not observed – until now – that smaller particles below 50 nanometers, such as particles produced by vehicles and industrial processes, could do the same.https://buff.ly/2E7NFU2
