Corrosion‐Protection of T122 Steel Using g‐C3N5‐Embedded Epoxy Coatings

Materials and Corrosion, EarlyView.
Study evaluates g‐C3N5 (CN) reinforced epoxy coatings on T122 steel in NaCl and H2SO4. Electrochemical tests revealed that 2% loading maximizes corrosion resistance by blocking pores and limiting ion diffusion, increasing Rp and Rn. Optimized CN content enhances epoxy coating performance overall system durability material. ABSTRACT Corrosion‐protection

Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Polymer and Polymer Composite‐Based Electrochemical Sensors for Real‐Time Detection of River Water Targeted Endocrine Disruptors

Macromolecular Symposia, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs) are pervasive environmental contaminants that interfere with hormone function and pose significant risks to ecosystems and human health. Their presence in river water necessitates sensitive, selective, and real‐time detection methods for effective monitoring and mitigation.

The Endocrine Disrupting Compounds Bisphenol‐A and α‐Zeranol Mimic the Estrogen Transcriptional Program to Promote Proliferation and Stemness in Breast Cancer Cells

Molecular Carcinogenesis, EarlyView.
ABSTRACT Excessive activation of the estrogen receptor (ER) drives proliferation, progression, and the formation of breast cancer stem cells (CSCs) in ER‐positive breast cancer. Estrogenic endocrine disrupting compounds (EDCs) found in plastics, water, and food are also able to bind to the ER.

Microbiological safety in the reuse of materials in home enteral nutrition: A quantitative in vitro experimental study

Nutrition in Clinical Practice, EarlyView.
Abstract Introduction In home enteral nutrition (HEN), the reuse of packaging and administration materials beyond the recommended period, combined with inadequate hygiene practice, increase the risk of microbiological contamination. This study assessed the risk through a simulation that reproduced real‐world usage conditions and hygiene practices ...

Cocktail effects of endocrine disruptors: bisphenols and human ovarian granulosa cells

, 2023
International audienceHuman population is exposed to endocrine disruptors (ED). The ban of BPA, an ED, in France and Canada in food industry, led to the emergence of structural analogs that are not yet regulated. The objectives of this project were to 1)

Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

Polymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...
