Article Synopsis
- - The study investigated a diverse group of 95 enzymes from the N-terminal nucleophile hydrolase superfamily, focusing on their ability to hydrolyze synthetic polyamides like nylon.
- - About 40% of these enzymes demonstrated significant nylon hydrolase activity, comparable to the well-known enzyme NylC, without any clear link between their evolutionary relationships and their hydrolytic capabilities.
- - Researchers identified several enzymes with strong substrate selectivity, especially those that efficiently processed Nylon 6,6, and also analyzed the crystal structure of a specific hydrolase to better understand the factors affecting its activity and selectivity.
The direct air capture (DAC) of CO2 using aqueous solvents is plagued by slow kinetics and interfacial barriers that limit effectiveness in combating climate change. Functionalizing air/aqueous surfaces with charged amphiphiles shows promise in accelerating DAC; however, insight into these interfaces and how they evolve in time remains poorly understood. Specifically, competitive ion interactions between DAC reagents and reaction products feedback onto the interfacial structure, thereby modulating interfacial chemical composition and overall function.

Efforts to design surfaces to enhance CO capture probabilities are challenging due to the remarkably poor understanding of chemistry and self-assembly taking place at these interfaces. Here, we leverage surface-specific vibrational spectroscopy, Langmuir trough techniques, and simulations to mechanistically elucidate how cationic oligomers can drive surface localization of amino acids (AAs) that serve as CO capture agents speeding up the apparent rate of absorption.

- Balanoposthitis is an inflammatory condition affecting the male genitals, more common in uncircumcised men, caused by infections, inflammation, autoimmune issues, or injury.
- Proper hygiene and moisturizers can alleviate most symptoms, but persistent cases may require testing for serious conditions like cancer.
- Modern research highlights microbiome differences between patients and healthy individuals, with specific bacteria linked to the severity of the condition, although the role of Gardnerella vaginalis in this disease remains uncertain.
Highly Recyclable and Tough Elastic Vitrimers from a Defined Polydimethylsiloxane Network.
Angew Chem Int Ed Engl
November 2023
Article Synopsis
- - Despite advancements in sustainable elastomers, creating elastic vitrimers with better mechanical properties and recyclability is still a challenge.
- - The study introduces a new design principle for highly durable and recyclable elastic vitrimers using crosslinked disulfide-containing PDMS chains and tetra-arm PEG, resulting in superior performance compared to traditional methods.
- - The new vitrimers, known as PDMS-disulfide-D, not only maintain their mechanical strength after recycling but also perform well in applications like electromyography sensors, highlighting their potential for practical use.
