The chemistry of exploding stars

(PhysOrg.com) -- Fundamental chemical processes in predecessors of our solar system are now a bit better understood: An international team led by Peter Hoppe, researcher at the Max Planck Institute for Chemistry in Mainz, ...

New methods for measuring reactive polysulfides in vegetables

The health-promoting effects of sulfur-rich vegetables such as onions and garlic have been known for a long time. How food containing sulfur compounds promotes health has not been easy to explore, as the levels—and types—of ...

Unearthing the sources of cave-forming sulfuric acid

A study published in the journal Geology uses isotopes of sulfur to fingerprint the sources of sulfuric acid that have carved unique and beautiful cave systems in the Pyrenees mountains of southern France.

Study shows chemical's extent in the Fairbanks winter air

A chemical compound discovered in 2019 in the wintertime air of Fairbanks, Alaska accounts for a significant portion of the community's fine particulate pollution, according to new research that seeks to better understand ...

Getting the most out of atmospheric data analysis

New particle formation in the atmosphere provides the nucleation centres required for the formation of clouds, making it an important process for understanding climate. Efforts to investigate the complex balance of chemistry ...

A clearer path to clean air in China

For more than 15 years, the Chinese government has invested billions of dollars to clean up its deadly air pollution, focusing intensely on reducing emissions of sulfur dioxide from coal-burning power plants.

Understanding sulfur's rotten smell

Though odorless in its normal state, utility companies add sulfur-containing odorants - called mercaptans or thiols - to the gas so it's easy to detect a leak. The foul smell is reminiscent of rotting cabbage or spoiled eggs.

Volcanoes cause climate gas concentrations to vary

Trace gases and aerosols are major factors influencing the climate. With the help of highly complex installations, such as MIPAS on board of the ENVISAT satellite, researchers try to better understand the processes in the ...
