Many cosmetics sold in the United States and Canada likely contain high levels of per- and polyfluoroalkyl substances (PFAS), a potentially toxic class of chemicals linked to a number of serious health conditions, according to new research from the University of Notre Dame. Scientists tested more ...
Researchers at Washington University in St. Louis reported the first observations of a new form of fluorine, the isotope 13F, described in the journal Physical Review Letters. They made their discovery as part of an experiment conducted at the National Superconducting Cyclotron Laboratory at ...
New solutions for fluorine chemistry
Two new catalysts for aromatics refinement using fluorine compounds and a new fluorine building block are among the results achieved at the Leibniz Institute for Catalysis in Rostock (LIKAT) in the past year. In laboratories around the world, fluorine is considered a hot element when it comes to ...
Chemists harness synergy effect of gallium
Chemists at Friedrich Schiller University Jena have demonstrated the value of “teamwork” by successfully harnessing the interaction between two gallium atoms in a novel compound to split the particularly strong bond between fluorine and carbon. The gallium compound is also cheaper and more ...
Water-based lithium-ion batteries would be safer to handle and easier to recycle
Lithium-ion batteries contain salts rich in fluorine, which decompose in humid air to toxic, highly corrosive hydrogen fluoride. The hazardous nature of this substance makes recycling more difficult and more expensive. A research project entitled "Fluoribat" is now being launched at Empa to solve ...
Novel fabrication method for affordable gas membranes
Researchers at the Department of Energy's Oak Ridge National Laboratory and the University of Tennessee, Knoxville, are advancing gas membrane materials to expand practical technology options for reducing industrial carbon emissions. Results published in Chem demonstrate a fabrication method for ...
Investigations with neutrons settle scientific dispute about the structure of fluorine
In toothpaste, Teflon, LEDs and medications, it shows its sunny side – but elemental fluorine is extremely aggressive and highly toxic. Attempts to determine the crystal structure of solid fluorine using X-rays ended with explosions 50 years ago. A research team has now clarified the actual ...
A method to replace hydrogen with fluorine in organic molecules makes drugs more effective
The development and improvement of pharmaceuticals plays the central role in the ongoing battle against human disease. Organic synthesis is the field that enables these developments as it offers the toolbox to diversify chemical structures. The group of Nuno Maulide, recently named the Scientist ...
Chemistry in clouds
Certain molecules with fluorine, chlorine or bromine, together with water, can release harmful substances into the atmosphere. The production of chlorofluorocarbons, which damage the ozone layer, has been banned as far as possible. However, other substances can also tear holes in the ozone layer ...
A fluorinated electron-acceptor unit for high performance organic semiconductors
Organic semiconductor materials have the potential to be used in innovative applications such as transparent and flexible devices, and their low cost makes their potential use particularly attractive. The properties of organic semiconductor materials can be tuned by controlling their structure at ...
