Nitrogen-containing compounds are often tolerated in oils and refined products because fuel specifications do not directly limit the nitrogen content of transportation fuels. The nitrogen content and ...

New studies highlight how thiosulfates not only supply sulfur but also significantly reduce nitrogen loss by slowing the conversion of ammonium to nitrate in the soil. Since 2017, Dr. Zack Ogles, ...

In a set of chemical firsts, University of Iowa researchers have created three polymers that incorporate nitrogen-sulfur groups: sulfenamides (–R 2 NSR–), diaminosulfides (–R 2 NSNR 2 –), and ...

Purdue Extension corn and soybean specialists share practical advice on reducing input costs without sacrificing crop yields.

(Nanowerk Spotlight) Sulfur is a very intriguing solution for the design of high energy density storage devices. The lithium-sulfur battery theoretically delivers energy density of 2600 Wh kg-1, which ...

OAKLAND, Calif.— Conservation and public-health groups today filed a formal notice of intent to sue the Environmental Protection Agency because the agency has failed to update air-pollution thresholds ...

In a number of biological processes, iron-sulfur clusters play a vital role, where they act as cofactors to enzymes. Research now shows that cubic clusters can support unusual bonding states. This ...

To extend the range of electric cars, automakers need new types of batteries that can store large amounts of energy. Lithium-sulfur batteries can, in theory, store two to three times more energy in a ...
