Forever Chemicals, Per-and Polyfluoroalkyl Substances (PFAS), in Lubrication

Lubricants
Per- and polyfluoroalkyl substances (PFAS), also known as forever chemicals, exhibit exceptional chemical stability and resistance to environmental degradation thanks to their strong C-F bonds and nonpolar nature.

Achieving Immanent Organizational Ethics: Managing Paradoxical Tensions in Packaging

Business Strategy and the Environment, EarlyView.
ABSTRACT Firms face strategic tensions in packaging materials through their conflicting but complementary social, environmental and economic goals in achieving sustainability. Reducing and repurposing plastics, glass, paper and cardboard in agriculture, horticulture and aquaculture is proving a challenge.

Mild C─F Activation of Azido(per)Fluoroalkanes

Chemistry – A European Journal, EarlyView.
Mild and selective activation of C(sp3)–F bonds in azido(per)fluoroalkanes using thiolates was developed, leading to novel functionalized azides. The reaction is initiated by nucleophilic attack of the sulfur atom to the terminal nitrogen of the azido group, followed by fluoride ion elimination.

Enabling Cross‐Coupling Reactivity of α‐Pentafluorosulfanyl Compounds with a Thermally Stable Organozinc α‐SF5 Reagent

Chemistry – A European Journal, EarlyView.
This work describes the first example of a thermally stable α‐SF5 organometallic reagent, which allows for extensive downstream functionalization by allylation and acylation reactions under copper catalysis, as well as palladium‐catalyzed Negishi‐type cross‐coupling conditions up to 96% yield. In silico analysis shines initial light on the requirements

Effects of Per- and Polyfluoroalkylated Substances on Female Reproduction

Toxics
Per- and poly-fluoroalkylated substances (PFAS) are a large group of chemicals that persist both in the environment and in the body. Legacy PFAS, e.g., perfluorooctanoic acid and perfluorooctane sulfonic acid, are implicated as endocrine disruptors and reproductive and developmental toxicants in epidemiological and animal model studies.

Silica Coating Enhances the PFAS Photocatalytic Properties of Boron Nitride

CleanMat, EarlyView.
A coating of 6 wt% SiO2 effectively covered the edges of BN, which lowered BN hydrolysis and increased PFOA photodegradation. ABSTRACT Boron nitride (BN) has recently emerged as a promising material capable of breaking down toxic perfluorooctanoic acid (PFOA) and other per‐ and polyfluoroalkyl substances (PFAS) through photocatalysis. However, chemical

Uncovering the Tumorigenic Blueprint of PFOS and PFOA Through Multi-Organ Transcriptomic Analysis of Biomarkers, Mechanisms, and Therapeutic Targets

Current Issues in Molecular Biology
Per- and polyfluoroalkyl substances (PFASs), called forever chemicals, persist in the environment and bioaccumulate, posing significant health risks. While epidemiological studies have linked exposure to specific PFAS types, perfluorooctanoic acid (PFOA)
