Reusable Polyphenol Building Blocks Enable Recyclable Epoxy‐Amine Thermosets via Methanolysis

Angewandte Chemie, EarlyView.
A biobased epoxy–amine platform was developed using functional building blocks derived from polyphenols. These thermosets exhibited tunable mechanical and thermal properties, together with efficient, catalyst‐free chemical recycling via methanolysis. Beyond the recovery of reusable building blocks, the recycled polyols could be further upcycled into ...

Bisphenol S causes excessive estrogen synthesis by activating FSHR and the downstream cAMP/PKA signaling pathway

Communications Biology
Estrogen excess in females has been linked to a diverse array of chronic and acute diseases. Emerging research shows that exposure to estrogen-like compounds such as bisphenol S leads to increases in 17β-estradiol levels, but the mechanism of action is ...

Binary Mixtures of Selected Bisphenols in the Environment: Their Toxicity in Relationship to Individual Constituents

Molecules, 2018
Bisphenol A (BPA) is one of the most popular and commonly used plasticizer in the industry. Over the past decade, new chemicals that belong to the bisphenol group have increasingly been used in industrial applications as alternatives to BPA. Nevertheless,

Simultaneous measurement of 16 bisphenol A analogues in house dust and evaluation of two sampling techniques

Emerging Contaminants, 2021
Bisphenol A (BPA) is a high production volume (HPV) chemical used to make polycarbonate (PC) plastics and epoxy resins. Due to its potential adverse health effects, BPA has been restricted or banned in some products and thus many alternatives to BPA have

Decoding Synergistic Pathways in Bimetallic MOFs for Advanced Oxidation Processes

Advanced Materials, EarlyView.
This review presents a unified framework linking metal pairing and framework design with electronic structure, redox cycling, oxidant activation, reactive‐species generation, and catalytic performance across photocatalytic and oxidant‐based BMOF‐AOPs. The resulting design principles guide the development of hydrolytically stable and efficient BMOFs for

A Tert‐Alkyl Terephthalate Derivative as a Universal Degradable Unit for Condensation Polymers

Angewandte Chemie, EarlyView.
A sterically bulky dicarboxylic acid core bearing a tertiary alkyl ester enables photocatalytic C─O bond cleavage via generation of a stabilized tertiary alkyl radical. Incorporated into polyarylate, polyurethane, and polyester, this universal trigger facilitates efficient degradation under identical conditions (up to 99% within 2–4 h). Remarkably, the

3D‐Printed Corneal Substitutes: Materials, Fabrication, and Preclinical Progress

Advanced Materials Technologies, EarlyView.
Successful clinical translation of 3D‐printed corneal substitutes relies on the interplay between the bioink properties, cellular component, and the fabrication process. These factors influence the critical properties of the construct, including optical transparency, mechanical stability, suture retention, that ultimately govern long‐term stromal ...
