Journal of Physics D: Applied published the first Plasma Roadmap in 2012 consisting individual perspectives 16 leading experts various sub-fields low temperature plasma science and technology. The 2017 is update a planned series periodic updates Roadmap. continuously growing interdisciplinary nature field its equally broad range applications are making it increasingly difficult to identify major challenges that encompass all many applications. This intellectual diversity ultimately strength...
Byproducts produced when treating perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) in water using a plasma treatment process intentionally operated to treat these compounds slowly allow for byproduct accumulation were quantified. Several linear chain perfluoroalkyl carboxylic acids (PFCAs) (C4 C7) identified as byproducts of both PFOA PFOS treatment. PFOA, perfluorohexanesulfonate (PFHxS), perfluorobutanesulfonate (PFBS) also found be from degradation. Significant...
Abstract The 2022 Roadmap is the next update in series of Plasma Roadmaps published by Journal Physics D with intent to identify important outstanding challenges field low-temperature plasma (LTP) physics and technology. format same as previous representing visions 41 leading experts 21 countries five continents various sub-fields LTP science In recognition evolution field, several new topics have been introduced or given more prominence. These emphasis highlight increased interests...
A process based on electrical discharge plasma was tested for the transformation of perfluorooctanoic acid (PFOA). The plasma-based adapted two cases, high removal rate and efficiency. During a 30 min treatment, PFOA concentration in 1.4 L aqueous solutions reduced by 90% with (76.5 W input power) 25% efficiency (4.1 power). Both achieved remarkably defluorination efficiencies compared to leading alternative technologies. also used treat groundwater containing several cocontaminants...
Per- and polyfluoroalkyl substances (PFASs) are an emerging class of contaminants raising increased levels concern due to their toxic, bioaccumulative, persistent nature. Current solutions for removing PFAS from contaminated water rely on adsorption-based methods where commonly used sorbents, example, activated carbons ion-exchange resins, exhibit low adsorption capacity a long equilibration time. Motivated by the generally deficient performance these current materials, this work addresses...
Harmful per- and polyfluoroalkyl substances (PFAS) are ubiquitously detected in aquatic environments, but their remediation remains challenging. Metal–organic frameworks (MOFs) have been recently identified as an advanced material class for the efficient removal of PFAS, little is known about fundamentals PFAS@MOF adsorption process. To address this knowledge gap, we evaluated performance 3 different MOFs 8 PFAS classes from aqueous film-forming foam-impacted groundwater samples obtained 11...
A pilot-scale plasma reactor installed into an 8 × 20 ft2 mobile trailer was used to rapidly and effectively degrade poly- perfluoroalkyl substances (PFAS) from liquid investigation-derived waste (IDW; development purge water monitoring wells) obtained 13 different site investigations at Air Force installations. In the raw water, numerous PFAS were detected in a wide concentration range (∼10-105 ng/L; total oxidizable precursors (TOP) ∼102-105 ng/L, fluorine by combustion ion chromatography...
Plasma, the fourth and most pervasive state of matter in visible universe, is a fascinating medium that connected to beginning our universe itself. Man-made plasmas are at core many technological advances include fabrication semiconductor devices, which enabled modern computer communication revolutions. The introduction low temperature, atmospheric pressure biomedical field has ushered new revolution healthcare arena promises introduce plasma-based therapies combat some thorny long-standing...
To determine the types of applications for which plasma-based water treatment (PWT) is best suited, treatability 23 environmental contaminants was assessed through in a gas discharge reactor with argon bubbling, termed enhanced-contact reactor.

Treatability compared terms observed removal rate constant (k obs). characterize influence interfacial processes on k obs, model developed that accurately...
"High-concentration" and "low-concentration" bench-scale batch plasma reactors were used to effectively degrade per- polyfluoroalkyl substances (PFAS) at a high concentration (∼100 mg/L) low (<1 μg/L), respectively, in ion exchange (IX) regenerant still bottom (SB) solutions. In the SBs, numerous PFAS detected with wide range (∼0.01 100 mg/L; total oxidizable precursors (TOP) ∼4000 10000 mg/L).

Electrical discharge plasma reactors with argon bubbling can effectively treat long-chain perfluoroalkyl acids (PFAAs) in contaminated water, and the addition of a cationic surfactant cetrimonium bromide (CTAB) is known to enhance removal short-chain PFAAs. However, roles PFAA chain length, functional group, water matrix properties on PFAA-CTAB complexation are largely unknown. This work investigated bulk liquid different PFAAs by CTAB absence plasma. Stepwise was subsequently used...
