6+ hour, 9+ min ago  (398+ words) Contamination from per- and polyfluoroalkyl substances, widely known as PFAS, continues to pose complex challenges for water authorities and environmental regulators worldwide. These synthetic chemicals, used in industrial processes, firefighting foams and a wide range of consumer goods, persist in…...

5+ day, 5+ hour ago  (588+ words) A new review analyses how the semiconductor industry handles per- and polyfluoroalkyl substances (PFAS), the forever chemicals that are deeply embedded in modern manufacturing. But their chemical stability, which makes them so useful on the factory floor, also makes PFAS…...

6+ day, 4+ hour ago  (1127+ words) It sounds dramatic, but from a chemistry and engineering perspective, it is not far from the truth. PFAS resist heat, water, oil, sunlight, and biological degradation. Those properties made them commercially valuable for decades. They are also the reason removing…...

1+ week, 1+ day ago  (421+ words) By eliminating the need for filtration and other labour-intensive preparation steps, the technology allows contaminants to be extracted directly from samples containing solid particles, such as sand or food residue. The project was led by Dr Ju Hyeon Kim at…...

1+ week, 6+ day ago  (515+ words) Advanced PFAS treatment technologies increasingly pair high'capacity capture with destructive steps to meet tightening drinking'water limits. Granular activated carbon performs well for long'chain PFAS, while anion exchange resins improve the removal of short'chain compounds but create spent media or regenerant…...

2+ week, 5+ day ago  (271+ words) The visit coincided with a major policy moment, as the UK Government formally unveiled its national strategy to tackle PFAS contamination across the environment. The timing underlined a shared focus between government and industry on addressing one of the most…...

3+ week, 1+ day ago  (654+ words) The plan marks a significant step toward addressing the long-term risks posed by per- and polyfluoroalkyl substances (PFAS), which are highly persistent and can remain in the environment for centuries. PFAS have become one of the most complex environmental challenges…...

3+ week, 5+ day ago  (545+ words) Often referred to as "forever chemicals," PFAS (per- and polyfluoroalkyl substances) persist in the environment and human bodies for decades, making early intervention critical. According to the report, if current levels of PFAS pollution continue unchecked until 2050, the total cost…...

1+ mon, 3+ day ago  (349+ words) Two further desirable properties are added to this long list of requirements. On the one hand, due to regulations governing food contact materials, no harmful substances may be transferred from the pan to the food. On the other hand, users…...

1+ mon, 1+ week ago  (747+ words) Having made over 20,000 individual tests, extensive lab validation of Nanize coatings has been undertaken, including by FTIR (Fourier-transform infrared spectroscopy), to verify polymer crosslinking, hard curing, durability and performance. Nanize ultra-rapidly cured polysilazane coatings are proven to create hard, durable,…...
