PFAS chemicals do not last forever
Once dubbed "forever chemicals," per-and polyfluoroalkyl substances, or PFAS, might be in the market for a new nickname......»»
Using sunlight to turn greenhouse gases into valuable chemicals
McGill University researchers have harnessed the power of sunlight to transform two of the most harmful greenhouse gases into valuable chemicals. The discovery could help combat climate change and provide a more sustainable way to produce certain ind.....»»
Exploring ternary metal sulfides as electrocatalysts for carbon dioxide reduction reactions
One of the most promising avenues for actively reducing CO2 levels in the atmosphere is recycling it into valuable chemicals via electrocatalytic CO2 reduction reactions. With a suitable electrocatalyst, this can be achieved under mild conditions and.....»»
New method to break down forever chemicals uses nanoparticles and ultrasound
What do firefighting foam, non-stick cookware, water-repellent textiles and pesticides all have in common? They all contain per- and polyfluoroalkyl substances, or PFAS—human-made chemicals that don't break down naturally. It's no wonder, then, tha.....»»
Enzyme-inspired catalyst puts chemicals in right position to make ethers
Taking inspiration from enzymes, chemists at the University of Illinois Urbana-Champaign developed a catalyst to simplify the synthesis of ethers, key functional components of many drugs, foods, personal care items and other consumer goods. The catal.....»»
Catalyzing environmental cleanup: A highly active and selective molecular catalyst and electrified membrane
Some chemicals create environmental problems; others, fortunately, can help clean them up. Chemists from Yale University and their colleagues have developed an electrochemical catalyst and membrane that offers an efficient and sustainable way to trea.....»»
Zeolite catalyst method uses microwaves to convert waste cooking oil into useful chemicals
Researchers from Kyushu University have revealed that a zeolite material called Na-ZSM-5 is effective in improving the chemical conversion of biomass into olefins—a precursor chemical that makes everything from plastics to pharmaceuticals—using m.....»»

New filter removes chemical contaminants from water even at very low concentrations
Pharmaceuticals and personal care products pose a major environmental threat. These chemicals, found in everyday items like medicines and cosmetics, can pollute waterways, harming the plants and animals living in the waterways and the humans who use.....»»
Industry and researchers call for action to tackle climate impact of organic, carbon-based chemicals
Industry experts and university researchers have joined together to ask the government to address the climate impact of organic, carbon-based chemicals......»»
Wildfires Are Contaminating Water Supplies
Wildfires don’t just destroy forest—they can increase sediment in rivers and reservoirs, spark algae blooms, and pollute watercourses with dangerous chemicals, leaving water providers to grapple with long-term consequences......»»
Chemists achieve PFAS-free synthesis of fluorinated pharmaceutical and agrochemical compounds
Chemists at the University of Amsterdam have developed a method to furnish a range of molecules with a trifluoromethyl group attached to a sulfur, nitrogen or oxygen atom. Their procedure, which is published in Science, avoids the use of PFAS reagent.....»»
Labor day crowds temporarily impact local streams, research shows
Crowds flocking to rivers and streams over Labor Day weekend are doing more than cooling off and having fun. They're temporarily introducing chemicals and microscopic organisms into their local waterways, according to new research from Johns Hopkins.....»»
What exactly are "forever chemicals"—and can we move beyond them?
The Australian parliament will conduct a national inquiry into the dangers of "forever chemicals.".....»»
Breaking down the indestructible: New technologies target PFAS environmental menace
PFAS are synthetic chemicals widely used in products such as non-stick cookware and waterproof clothing due to their water and grease-resistant properties. However, their persistence in the environment has led to widespread contamination and signific.....»»
Scientists help turn whisky waste into valuable commodity
A new method to extract valuable bio-based chemicals from whisky distillery waste streams could transform manufacturing and be worth up to £90 million in global chemical manufacturing markets......»»
Massachusetts governor signs law phasing out toxic PFAS in firefighters" gear
Massachusetts Gov. Maura Healey signed into law Thursday a bill that would phase out the use of PFAS, a group of toxic industrial compounds, in firefighters' protective gear......»»
Chemical cocktail from plastics: Pilot study describes degradation and leaching process of plastic consumer products
Plastic waste in rivers and oceans is constantly releasing chemicals into the water. Until now, it was unknown how large these quantities are and which substances are released particularly strongly. In the large-scale P-LEACH project, experts from fo.....»»

Scientists use carbon isotopes to track "forever chemicals"
Organofluorine compounds—sometimes called "forever chemicals"—are increasingly turning up in our drinking water, oceans and even human blood, posing a potential threat to the environment and human health......»»
More microbes found that break down the carbon-fluorine bonds found in some unsaturated PFAS
A team of chemical and environmental engineers at the University of California Riverside, working with colleagues from the University of California Los Angeles, has found a class of microbes that consume PFAS in the environment and sever some of the.....»»
