Transformative Masked Ortho‐Quinone Chemistry: From Direct Guaiacol Activation to Lignin‐Based Adhesives

Angewandte Chemie International Edition, EarlyView.
Renewable guaiacols are rapidly oxidized by phenyliodine(III)diacetate to masked ortho‐quinones, giving a new class of monomers that undergo selective Michael‐type polyaddition with multithiols to from thiol‐guaiacol connectivity‐bearing polymers. The activation applies to discrete monomers and directly to lignin, enabling two‐component adhesives that ...

Determination of bisphenol A, bisphenol F, bisphenol A diglycidyl ether and bisphenol F diglycidyl ether migrated from food cans using Gas Chromatography-Mass Spectrometry

Czech Journal of Food Sciences, 2003
Varnishes used for the inner coatings of food cans are mostly based on epoxy resins or vinylic organosols. The epoxy resins are produced from bisphenol A and bisphenol F and they also contain BADGE or BFDGE as stabilising components.

Glyoxylic‐Acetal‐Based Gel‐Polymer Electrolytes for Lithium‐Ion Batteries

Batteries &Supercaps, Volume 8, Issue 3, March 2025.
A safe electrolyte based on tetraethoxyglyoxal (LE) is combined with a methacrylate polymer matrix. The resulting gel‐polymer electrolyte (GPE) exhibits an increased flash point, suitable ionic conductivity, and a stable performance in lithium‐ion battery cells.

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

BMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Impact of bisphenol A, F, AF, C, and S on rumen ecology: an exploratory in vitro screening

Italian Journal of Animal Science
Ruminants consume significant quantities of biomass, representing a primary pathway for xenobiotic exposure due to pollutant accumulation in plants. This exploratory in vitro screening aimed to evaluate the short-term impact of bisphenol A (BIS_A) and ...

Bisphenol S, a New Bisphenol Analogue, in Paper Products and Currency Bills and Its Association with Bisphenol A Residues

, 2012
As the evidence of the toxic effects of bisphenol A (BPA) grows, its application in commercial products is gradually being replaced with other related compounds, such as bisphenol S (BPS). Nevertheless, very little is known about the occurrence of BPS in

Tailoring the synergistic effect of integrated polypyrrole hydrogel on the adsorption activity of rice husk-based activated carbon (polypyrrole/activated carbon composite) for bisphenol-A and 4-chlorophenol: experimental and theoretical analysis

Frontiers in Bioengineering and Biotechnology
Rice husk-derived activated carbon was hybridized with polypyrrole hydrogel (Pyh), producing advanced nanocomposite (Pyh/AC). The composite was applied as an enhanced adsorbent for two forms of toxic phenolic compounds, particularly bisphenol-A (BSP-A ...

Bisphenol A in dummies

, 2009
The Federal Institute for Risk Assessment (BfR) examined dummies made of latex and sili-cone for bisphenol A. The goal was more particularly to determine how much bisphenol A migrates from the dummies during use.
