Novel nitro‐quinoline photoinitiators for composites: exploring the effects of hydroxyl and methacrylate substituents on the photopolymerization of dimethacrylate matrices

Polymer International, EarlyView.
New quinoline derivatives proved to be efficient photoinitiators for dental resin monomers under two different light‐curing units, yielding favorable conversion, color and fluorescence results in the presence of different co‐initiators, including an eco‐friendly alternative.

Viscoelastic Modeling of Stress Relaxation in Model High‐Performance Covalent Adaptable Networks

Journal of Polymer Science, EarlyView.
Covalent adaptable networks, often referred to as vitrimers, contain a certain fraction of bonds that are able to exchange with other bonds. The ability of this bond exchange to relax stress or result in flow of the material depends on the concentration and specific concentration of these bonds in ways that can be quantified.

Bisphenols and Phthalates in Bottled Mineral Water: First Evidence of Co‐Occurrence, Estrogenic Activity, and Health Risk in Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Bisphenol A (BPA), its structural analogs, and phthalates are synthetic chemicals widely used, with documented endocrine‐disrupting activity. This study aimed to develop and validate a selective multiresidue analytical method for the simultaneous determination of BPA, 10 bisphenol analogs, and six phthalates in PET‐bottled mineral water.

Bisphenol Analogues in Sediments from Industrialized Areas in the United States, Japan, and Korea: Spatial and Temporal Distributions

, 2016
Bisphenol analogues are used in the production of polycarbonate plastics and epoxy resins. Despite the widespread use of bisphenols, few studies have reported the occurrence of compounds other than bisphenol A (BPA) in sediment.

From Consumer Plastics to Aquatic Toxicants: Oxidative and Endocrine Effects of Microplastics on Fathead Minnow (Pimephales promelas) Larvae

Environmental Toxicology, EarlyView.
ABSTRACT Secondary microplastics (MPs) from single‐use consumer products are rapidly becoming one of the most persistent and widespread pollutants of our time. Freshwater systems act as early sinks for MPs where fragmentation and additive leaching expose aquatic life to a broad spectrum of toxic compounds.

Bisphenol AF and Bisphenol B Exert Higher Estrogenic Effects than Bisphenol A via G Protein-Coupled Estrogen Receptor Pathway

, 2017
Numerous studies have indicated estrogenic disruption effects of bisphenol A (BPA) analogues. Previous mechanistic studies were mainly focused on their genomic activities on nuclear estrogen receptor pathway.

Influence of Octaglycidyl‐POSS on Processing Behavior, Gelation Kinetics, and Thermomechanical Properties of a DGEBA/Polyamidoamine Epoxy System

Journal of Vinyl and Additive Technology, EarlyView.
The rigid, octafunctional Si8O12 cage of OG‐POSS incorporates into the DGEBA/polyamidoamine network as a multifunctional junction, raising the glass transition temperature (Tg) by up to 19°C and the apparent crosslink density non‐monotonically by 47%‐71% at 1.5, 3.0, and 5.0 phr loading.

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 ...
