Molecular Simulation of Functionalized Covalent Organic Framework Membranes for Inorganic Salt Separation

Advanced Theory and Simulations, EarlyView.
Six functionalized TpPa‐based covalent organic frameworks (COFs) are characterized using nonequilibrium molecular dynamics simulations to assess water permeance and salt rejection. The TpPa‐SO3H COF membrane achieves the highest sodium sulfate rejection (>98%) while maintaining relatively high water permeance compared to commercial nanofiltration ...

Polystyrene Microplastics Exposure Aggravates Clear Cell Renal Cell Carcinoma Progression via the NF‐κB and TGF‐β Signaling Pathways

Advanced Science, EarlyView.
This research provides the first comprehensive evidence that PS‐MPs exacerbate ccRCC progression by activating the NF‐κB and TGF‐β pathways. These findings establish PS‐MPs as an environmental risk factor for ccRCC progression and identify the NF‐κB and TGF‐β signaling as potential therapeutic targets to mitigate the adverse effects of ‐PS‐MPs exposure.
