PFAS properties and destruction methods: A focus on enzymatic degradation

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract Per‐ and polyfluoroalkyl substances (PFAS) are known as ‘forever’ chemicals and have lasting detrimental impact on the environment and living organisms. To understand PFAS molecules better, this review begins with an overview of PFAS definition, classifications and applications, and then provides a comprehensive summary and critical analysis ...

Percutaneous Closure of Patent Foramen Ovale in a Patient With Incomplete Cor Triatriatum Sinister: A Case Report

Journal of Clinical Ultrasound, EarlyView.
We present the case of a 55‐year‐old male who experienced a cryptogenic ischemic stroke, likely due to a patent foramen ovale (PFO) in the setting of an incomplete cor triatriatum sinister (CTS) and a 30 mm GORE Cardioform Septal Occluder was successfully implanted.

PFAS Removal During Pyrolysis of Biosolids Is Affected by Initial PFAS Concentration and Pyrolysis Efficiency. [PDF]

Water Environ Res
Pyrolysis of industrially impacted biosolids at 800°C removed PFAS to below detection limits in biochar but PFOS still remained in biochar produced at 500°C. ABSTRACT Current and pending biosolids regulations related to per‐ and polyfluoroalkyl substances (PFAS) have triggered the industry to consider emerging biosolids treatment processes.

Characteristics, properties and limitations of per‐ or polyfluoroalkyl substances (PFASs) and fluoropolymers

Polymer International, EarlyView.
An overview and categorization of man‐made per‐ or polyfluoroalkyl substances (PFASs) including low‐molar‐mass and high‐molar‐mass fluorochemicals, and their international regulations is presented. Though certain PFASs are toxic, bioaccumulative and cross the human cellular membranes, others, such as fluoropolymers, are safe, reliable and involved in ...

PFAS Removal by Anion‐Exchange Block Copolymer Membranes Featuring Highly Ordered Alternating Gyroid Nanochannels

Journal of Polymer Science, EarlyView.
Engineering positively charged alternating gyroid nanochannels in block copolymer membranes provides a powerful tool for efficient PFAS removal. ABSTRACT Ion‐exchange resins (IERs) can effectively remove per‐ and polyfluorinated alkyl substances (PFAS) from water through electrostatic interactions between the negatively charged PFAS and the positively ...

Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes

Small, EarlyView.
This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

Extending the semi-empirical PM6 method for carbon oxyacid pKa prediction to sulfonic acids: Application towards congener-specific estimates for the environmentally and toxicologically relevant C1 through C8 perfluoroalkyl derivatives [PDF]

, 2009
A positive bias in the semi-empirical PM6 method for estimating pKa values of sulfonic acids was corrected by a correlation developed between non-adjusted PM6 pKa values and the corresponding experimentally obtained/estimated acidity constants for a ...

Surface‐Engineered ZnO Nanoparticles via Acetone Immersion for Charge‐Balanced High Resolution Full‐Color Organic Light Emitting Diode Displays

Small, EarlyView.
Acetone post‐immersion of OLEDs effectively passivates oxygen vacancies in the ZnO electron transport layer, reducing charge trapping and enhancing electron injection. This improves hole‐blocking at the interface and decreases exciton quenching in the emission layer, resulting in significantly enhanced electrical and optical device performance ...
