An Arthrobacter citreus strain suitable for degrading ε-caprolactam in polyamide waste and accumulation of glutamic acid [PDF]
ε-Caprolactam-a toxic xenobiotic compound present in industrial polyamide waste was found to be degraded by caprolactam-degrading bacteria. Arthrobacter citreus was able to utilize up to 20 g ε-caprolactam/l as the sole source of carbon more efficiently ...

A Circular and Tacticity-Independent Crystalline Mono-Substituted Nylon-6 Platform: Unexpected Large Positional Effects on Crystallizability and Performance. [PDF]
Methyl substitution positions on the nylon‐6 backbone markedly affect crystallizability, thermomechanical properties, and recyclability of the resulting atactic nylon‐6 variants. While γ‐methyl substitution gives an amorphous nylon, all other four methyl‐substitution positions (α, β, δ, and ε) afford, unexpectedly, crystalline nylons, showing tacticity‐

Enhanced Drug Skin Permeation by Azone-Mimicking Ionic Liquids: Effects of Fatty Acids Forming Ionic Liquids [PDF]
Background/Objectives: Laurocapram (Azone) attracted attention 40 years ago as a compound with the highest skin-penetration-enhancing effect at that time; however, its development was shelved due to strong skin irritation.

Defined Nylon Oligomers Enable Mechanistic Insight Into Enzymatic Polyamide Depolymerization. [PDF]
The remarkable progress in enzymatic polyester depolymerization has demonstrated the potential of biocatalysis for sustainable polymer recycling. In contrast, enzymatic polyamide (PA) degradation remains poorly understood, largely due to the lack of defined and accessible model substrates.

Sustainable recycling of polyamides via C–N bond cleavage facilitated by methyl tosylate under mild conditions [PDF]
The escalating issue of plastic “white pollution” urgently calls for efficient and sustainable recycling strategies. Herein, we propose an approach for the depolymerization of polyamides via alcoholysis, utilizing methyl tosylate as an activator to ...
