First direct evidence that elemental fluorine occurs in nature
A special fluorite, the “fetid fluorite” or “antozonite,” has been the subject of many discussions for nearly 200 years. This mineral emits an intensive odor when crushed. Now, for the first time, scientists from the Technische Universitaet Muenchen and the Ludwig-Maximilians-University Munich have successfully identified natural elemental fluorine in this fluorspar. They report their results […]

Breaking the carbon-fluorine bond
US chemists have discovered a new way to break the bond between carbon and fluorine atoms – the strongest carbon bond there is. The reaction, which is mediated by an iridium complex and proceeds in an unexpected way, is important because many pharmaceuticals and agrichemicals incorporate C-F bonds. The research suggests possible routes for the […]

Hydrogen fluoride is ubiquitous throughout the Milky Way
ESA’s Herschel infrared space observatory has found that hydrogen fluoride molecules are everywhere in interstellar gas clouds. They betray hidden reservoirs of gas, and may ultimately become a key tracer of star-forming gas clouds in distant galaxies. Hydrogen is the most abundant element in the Universe, making up three-quarters of the normal matter. But at […]
