Hydrogen fuel: Inexpensive, efficient bi-metallic electrocatalysts may open floodgates for hydrogen fuel

University of Delaware researchers have discovered a cheap and efficient catalyst for converting water to hydrogen fuel (known as hydrogen evolution), a vital step in making hydrogen a viable and sustainable energy source.

“The rising concerns about carbon dioxide emissions have led to a growing realization that it is not possible to sustain the world’s current development without a substitution of clean and renewable energy,” writes Feng Jiao, assistant professor of chemical and biomolecular engineering and a co-author on the paper published in the current issue of Nature Communications. “Hydrogen is a potential clean fuel for our society.”  (more…)

Pesticide Accumulation in Sierra Nevada Frogs

SACRAMENTO, Calif. — A study on frogs in remote Sierra Nevada mountain habitats including Yosemite National Park and Giant Sequoia National Monument, detected concentrations of pesticides in frog tissue that potentially came from California’s Central Valley sources. 

“Our results show that current-use pesticides, particularly fungicides, are accumulating in the bodies of Pacific chorus frogs in the Sierra Nevada,” says Kelly Smalling, a research hydrologist with the U.S. Geological Survey and lead author of the study. “This is the first time we’ve detected many of these compounds, including fungicides, in the Sierra Nevada. The data generated by this study support past research on the potential of pesticides to be transported by wind or rain from the Central Valley to the Sierras.” (more…)
