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.

Dominant Frequency Mapping as a Functional Tool for Substrate‐Guided Ventricular Tachycardia Ablation

Journal of Cardiovascular Electrophysiology, EarlyView.
Stimulus‐independent DF mapping integrates intracardiac signals with 3D anatomy to visualize high‐DF activity, with regions derived from SmartTouch and Pentaray catheters showing spatial correspondence with operator‐defined ablation sites. Quantitative analysis demonstrates higher proximity scores at ablation sites, low projection error, and good ...

Selective Introduction of Acid Sites in Different Confined Positions in ZSM-5 and Its Catalytic Implications

ACS Catalysis, 2018
Controlling the location of acid sites in zeolites can have a great effect on catalysis. In this work we face the objective of directing the location of Al into the 10R channels of ZSM-5 by taking advantage of the structural preference of B to occupy ...

Soft tissue abnormalities in the congenital limb malformation radial dysplasia (RD): Their clinical impact and treatment significance

Journal of Anatomy, EarlyView.
We review the characteristic changes to the limb soft tissue and neurovascular abnormalities that have been described in the congenital limb birth defect, Radial Dysplasia. These include consistent changes in muscle anatomy or absence of specific muscles, persistent median arteries and absent radial arteries and consistent alterations in neural ...

The Real Structure of Intergrown ZSM‐5/ZSM‐11 Industrial Zeolite Catalysts

Small Structures
In some industrial‐scale reactions, an intergrowth of ZSM‐5 and ZSM‐11 aluminosilicate zeolites is the preferred catalyst. These structures each have two intersecting channel systems with 10‐ring windows, defined by 10 oxygen atoms. The channels are both
