Producing ammonia through electrochemical processes could reduce carbon dioxide emissions
Ammonia is commonly used in fertilizer because it has the highest nitrogen content of commercial fertilizers, making it essential for crop production. However, two carbon dioxide molecules are made for every molecule of ammonia produced, contributing to excess carbon dioxide in the atmosphere. A team from the Artie McFerrin Department of Chemical Engineering at Texas […]
Carbon-coated nickel enables fuel cell free of precious metals
A nitrogen doped carbon-coated nickel anode can catalyze an essential reaction in hydrogen fuel cells at a fraction of the cost of the precious metals currently used, Cornell University researchers have found. The new discovery could accelerate the widespread use of hydrogen fuel cells, which hold great promise as efficient, clean energy sources for vehicles […]
Capturing the impact of human sewage on Earth’s coastal ecosystems: New worldwide mapping analysis identifies key exposure hotspots in unprecedented resolution
A first-of-its-kind, high-resolution mapping analysis estimates the amounts of nitrogen and pathogens released into coastal ecosystems from human wastewater sources around the world. Cascade Tuholske (now affiliated with the Columbia Climate School) and colleagues at the University of California, Santa Barbara, present this research in the open-access journal PLOS ONE on November 10, 2021. Human […]
