Removal of Natural Organic Matter Fractions by Kaolin/Fly Ash Ceramic Microfiltration Membrane in Drinking Water: Insights from a Laboratory Scale Application

Advanced Materials Interfaces, EarlyView.
The prepared ceramic membrane exhibited 28.84 µm average pore size and hydrophilic properties (≈27.4° contact angle). FTIR shows the presence of aluminol, siloxane, and hydroxyl groups and XRD confirms the presence of quartz and kaolinite phases. Separation of natural organic matter from drinking water is achieved by microfiltration at 0.25 bar and is ...

Using QCM‐D for Real‐Time Analysis of Cell Adhesion Dynamics at Biointerfaces

Advanced Materials Interfaces, EarlyView.
This study explores adhesion of human fibroblasts to functionalized biomaterial surfaces. Quartz crystal microbalance with dissipation (QCM‐D) is used to measure cell responses in real time. The QCM‐D signalis correlated with changes in cell morphology and focal adhesion kinase (FAK) activation. This data shows a positive correlation between the energy

High‐Yield, Cost‐Effective Fabrication of High‐Aspect‐Ratio Polyimide Microstructures for Robust Superhydrophobic Surfaces

Advanced Materials Interfaces, EarlyView.
This study presents robust polyimide superhydrophobic surfaces with excellent mechanical durability, thermal stability, and chemical stability. A high‐yield and cost‐effective method to fabricate high‐aspect‐ratio polyimide surface microstructures is developed by controlling the template surface treatment, precursor molecular weight, and vacuum process

Direct Observation of Dry Etch‐Induced Selectivity Tailoring of Alkylate Inhibition Layer Using DMATMS Vapor

Advanced Materials Interfaces, EarlyView.
This study demonstrates that tailoring surface ─OH groups on SiO2 and SiNx via dry etching significantly enhances the selectivity of DMATMS adsorption, achieving a 92.2% selectivity in subsequent Ru layer growth. In situ spectroscopy reveals that removal of ─OH groups reduce DMATMS reactivity on SiNx but not on SiO2, providing insights for improving ...

Mechanistic Insights Into Proton and Oxygen Transport Through Ultrathin Amorphous Al2O3 and Al2O3‐SiO2 Electrocatalyst Overlayers

Advanced Materials Interfaces, EarlyView.
Ultrathin amorphous alumina electrocatalyst overlayers block oxygen reduction while cathodic‐driven structural relaxation accelerates proton transport over time. By contrast, ultrathin aluminosilicate coatings allow proton permeation but cannot suppress oxygen.
