Photooxidation of blends of vinyl alcohol – vinyl acetate copolymer with polyhydroxybutyrate
The influence of poly(3-hydroxybutyrate) (10-20 weight %) on the expenditure and accumulation of chromophore groups was studied, as well as oxygen absorption upon photooxidation of a vinyl alcohol - vinyl acetate copolymer. The article suggests a kinetic

Ferrocene and Ferrocenium Modified Clays and Their Styrene and EVA Composites [PDF]
In this work, ferrocene- and ferrocenium-containing salts were employed to modify montmorillonite. X-ray measurements show an increase in the interlayer spacing upon clay modification, which means that the larger and more organophilic cations were ...

A novel methodology for the construction of aromatic and heteroaromatic trifluoropropynyl derivatives has been developed. The new protocol is based on a tandem Sonogashira cross‐coupling reaction between a bench‐stable trifluoropropynyl carbinol reagent, generated from the commercially available and inexpensive hydrofluoroolefin‐1234yf gas, and (hetero)

A Degradable Bioinspired Flier with Aerogel‐Based Colorimetric Sensors for Environmental Monitoring
Biodegradable fliers are developed inspired by Tipuana tipu samaras, integrating cellulose nanocrystal aerogel (CNCa) sensors loaded with natural dyes for pH and ammonia detection. The lightweight, degradable fliers mimic natural morphology and aerodynamics, offering an eco‐friendly, scalable solution for in situ environmental monitoring after passive ...
