The Punjab Forensic Science Agency (Urdu: پنجاب فرانزک سائینس ایجنسی, abbreviated as PFSA) is a government agency under the Home Department, of the provincial Government of Punjab of Pakistan. It provides forensic science services primarily to law enforcement in the province. The Punjab Forensic Science Agency act was ...
The process does not work on perfluorosulfonic acids such as PFOS. [235] A 2022 study published in Chemical Science shows breakdown of C-F bonds and their mineralization as YF 3 or YF 6 clusters. [236] Another study in the Journal of the American Chemical Society described the PFASs breakdown using metal-organic frameworks (MOFs). [237]

Simply Orange Juice is accused of deceiving health-conscious customers into believing one of its juices is “all natural” as labeled — but it’s not, a class-action lawsuit says.
One of the most common and commercially available PEM materials is the fluoropolymer (PFSA) [2] Nafion, a DuPont product. [3] While Nafion is an ionomer with a perfluorinated backbone like Teflon, [4] there are many other structural motifs used to make ionomers for proton-exchange membranes. Many use polyaromatic polymers, while others use ...
The Prime Minister of Poland (President of the Council of Ministers) appoints the chairperson of the PFSA. [citation needed]The Polish Financial Supervision Authority (PFSA) exercises supervision over the banking sector, capital market, insurance and pension markets, supervision over payment institutions and payment service offices, electronic money institutions and the cooperative credit ...
Compared to liquid electrolytes, a polymeric membrane has a much lower chance of leakage [2]. The proton-exchange membrane is commonly made of materials such as perfluorosulfonic acid (PFSA, sold commercially as Nafion and Aquivion), which minimize gas crossover and short circuiting of the fuel cell. A disadvantage of fluor containing polymers ...
Perfluorosulfonic acids (PFSAs) are chemical compounds of the formula C n F (2n+1) SO 3 H and thus belong to the family of perfluorinated and polyfluorinated alkyl compounds (PFASs).
