The Catalytic Curing Reaction and Mechanical Properties of a New Composite Resin Matrix Material for Rocket Fuel Storage Tanks

open access: yesApplied Sciences, 2023
In this paper, an equimolar blend of bisphenol A dipropargyl ether and cyanate ester was selected to study the effect of different catalysts on the curing reaction of a bisphenol A dipropargyl ether and cyanate ester blended resin system, and the thermal

Urinary Free Bisphenol A and Bisphenol A-Glucuronide Concentrations in Newborns [PDF]

open access: yesThe Journal of Pediatrics, 2013
Infants are exposed to the endocrine disruptor bisphenol A (BPA) through breast milk and baby formula. Detoxication by conjugation of BPA may be limited in infants. We demonstrate BPA exposure in 11 neonates and 1 young infant, but find no evidence of a low capacity for BPA conjugation.

Facet‐Engineered S‐Scheme Heterostructure With Enhanced Active Sites for Efficient Photocatalytic Degradation of Organic Contaminants

open access: yesAdvanced Functional Materials, EarlyView.
The facet‐engineered ZnO/Zn3In2S6 heterostructure, dominated by {001} plane coupling, exposes abundant unsaturated Zn sites with elongated Zn─O bonds, directing photoexcited charge carriers along an S‐scheme pathway and suppressing recombination. Enhanced interfacial Zn adsorption toward bisphenol A and methylene blue further synergistically promotes ...

Two‐Way Shape Memory Alloy and Polymer Composite Hybrid Smart Actuator With High Speed, Accuracy, and Reversible Deformation

open access: yesAdvanced Functional Materials, EarlyView.
Tailored thermo‐mechanical properties of shape memory polymer composites enable large reversible deformation as well as high actuation speed. Moreover, a structural design with curvature in the transverse direction achieves sub‐second actuation on heating and a larger recovery ratio on cooling. Finally, these newly developed smart two‐way actuators can

Bisphenol F and Bisphenol S in a Complex Biomembrane: Comparison with Bisphenol A

open access: yesJournal of Xenobiotics
Bisphenols are a group of endocrine-disrupting chemicals used worldwide for the production of plastics and resins. Bisphenol A (BPA), the main bisphenol, exhibits many unwanted effects. BPA has, currently, been replaced with bisphenol F (BPF) and bisphenol S (BPS) in many applications in the hope that these molecules have a lesser effect on metabolism ...

BPA-free? Exploring the reproductive toxicity of BPA substitutes BPS and BPF on endometrial decidualization

open access: yesEcotoxicology and Environmental Safety
Bisphenol A (BPA) exposure is linked to multiple adverse health outcomes, prompting the rise of ''BPA-free'' products. However, substitutes like Bisphenol S (BPS) and Bisphenol F (BPF) are equally prevalent, with detection frequencies and concentrations ...
