Beyond Traditional Phenolics: Disulfide Bonds for Performance Enhancement of Aerospace Ablation‐Resistant Materials from Processing to Recycling

Advanced Science, EarlyView.
The dynamic disulfide bonds facilitated the development of high‐performance aerospace ablation‐resistant materials. At moderate temperature, the dissociation and recombination of disulfide bonds ensured excellent processability, mechanical properties, and recycling ability of phenolic resin; at high temperature, cleavage of disulfide bonds produced ...

Urinary Bisphenols as Biomarkers of Exposure to Bisphenol A, Bisphenol F, and Bisphenol S: A New Procedure for Biomonitoring

Laboratories
Introduction. Bisphenols are chemicals widely used in industrial production, but they are also of significant concern due to their potential health effects. In particular, bisphenol A (BPA) is a documented endocrine disruptor. As a result, bisphenol S (BPS) and bisphenol F (BPF) are now frequently used as substitutes.

Molecular‐Level Pore Engineering for Precise Separation via Active Solvent‐Mediated Interfacial Polymerization

Advanced Science, EarlyView.
We demonstrate that microemulsion solvents can actively template molecular‐level pores within selective layer during interfacial polymerization. By creating localized quasi‐homogeneous polymerization zones, the membrane achieved a 7.1‐fold enhancement in water permeance with increased selectivity.

Developing Highly Effective Nanoparticle mRNA Therapeutic for Pediatric Acute Respiratory Distress Syndrome

Advanced Science, EarlyView.
Sepsis‑induced pediatric acute respiratory distress syndrome suppresses FOXF1 in lung endothelial cells which causes life‐threatening lung damage. To counter this, researchers developed nanoparticles that specifically target these cells and deliver FOXF1 mRNA.

Synthesis of Tetrachloro-Bisphenol A by Chlorination of Bisphenol A

The Journal of the Society of Chemical Industry, Japan, 1971
一般液相塩素化触媒を用い, 酢酸溶媒中で BPA の塩素化を行ない, 塩化アルミニウム触媒が最も適当な触媒と認めた。反応条件は BPA 仕込み濃度 10%, 触媒濃度 1% 以上, 反応温度 30～33℃ が適切であった。触媒の選択作用は強く, 無触媒とは異なった選択逐次反応で進行する。Cl2流速/BPA (l/min・mol) 0,25～0.60 の各実験における BPA の消失速度から擬一次反応の成立が確認され, その速度定数たと反応時間tの積τ と BPA,反応中間物の濃度の関係はほぼ同一曲線上にプロットされた。その曲線から, 試行錯誤により求められた各中間物の相対速度定数Kは, K2=k2/k1=1.3, K2=k3/k1=1.2, K4=k4/k1=1.8, K5=k5/k1=≒0 ...

Transformative Chemie maskierter Ortho‐Chinone: Über die direkte Aktivierung von Guajacol zu Lignin‐basierten Klebstoffen

Angewandte Chemie, EarlyView.
Erneuerbare Guajacole werden durch Phenyliodid(III)diacetat rasch zu maskierten ortho‐Chinonen oxidiert und bilden eine neue Monomerklasse, die mit Multithiolen selektive Michael‐Typ‐Polyadditionen zu Polymeren mit Thiol‐Guajacol‐Verknüpfungen eingeht.
