Novel Zwitterionic Polydopamine Nanofiller‐Reinforced Hybrid Membranes With Superior Antifouling Performance for Wastewater Treatment

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reports one‐pot synthesized novel zwitterionic polydopamine‐silica (ZSiPDA) nanofillers for fabricating PES hybrid ultrafiltration membranes with enhanced hydrophilicity, permeability, and antifouling performance. The optimized membrane achieved over 91% humic acid removal and showed strong potential for municipal wastewater treatment.

Synthetic Strategies for the Construction of Cyclobutane‐Fused Heterocycles

European Journal of Organic Chemistry, EarlyView.
Cyclobutane‐fused heterocycles are important motifs commonly present in bioactive compounds, recognized for their rigid 3D structures that confer unique properties. However, synthesizing these compounds remains challenging. This review discusses current methods for their synthesis, such as photochemical, metal‐catalyzed, and Lewis acid‐mediated [2 + 2]

Development of Polyamide 6/Compound by Recycled Rubber Blends Using Graphitized Polyethylene or Polypropylene with Maleic Anhydride as Compatibilizer Agent

Journal of Aerospace Technology and Management, 2013
http://dx.doi.org/10.5028/jatm.v5i2.164 The toughening of polyamide 6 is desirable for many applications and may be obtained by adding a phase to the elastomeric matrix. However, this leads to a loss in its rigidity characteristics.
