A Highly Stable Organic–Inorganic Hybrid Electron Transport Layer for Ultraflexible Organic Photodiodes

Advanced Materials, EarlyView.
Organic photodiodes (OPDs) with low dark current and stable detectivity under light irradiation, air exposure, and heating are realized using a nanoparticle‐based Zn‐chelated PEIE (PEI‐Zn NP) electron transport layer. This formulation effectively suppresses photocurrent degradation and dark current increase, ensuring enhanced environmental stability ...

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 ...

Microneedles with Interdigitated Electrodes for In Situ Impedimetric VEGF Sensing

Advanced Materials Interfaces, EarlyView.
An electrochemical device for transdermal monitoring based on flexible polylactide microneedles with interdigitated electrodes enables continuous monitoring of vascular endothelial growth factor (VEGF) in interstitial fluid. Gold‐coated microneedles functionalized with anti‐VEGF antibodies, provide an in situ detection platform with high sensitivity ...

Stress Response of Aspergillus niger Spores to Copper Surfaces and the Implications for Antifungal Surface Functionalization

Advanced Materials Interfaces, EarlyView.
This study investigates the antifungal efficacy of ultrashort pulsed laser‐induced periodic surface structures (USP‐DLIP) on copper, brass, and steel surfaces. Using Aspergillus niger as a model, the research highlights a 99% reduction in spore viability on 9 µm structured copper surfaces due to enhanced copper ion release. Scanning electron microscopy
