Surface Functionalized Ti3CNTx MXene for Monitoring Sweat pH with Superhydrophobic Protection

Advanced Materials Interfaces, EarlyView.
The highly sensitive, stable, and superhydrophobic pH sensor is made by functionalizing the Ti3CNTx MXene surface with fluoroalkyl silane grafting. This strategy is expected to push forward the application of MXene in sweat pH sensing in the near future. Abstract Real‐time tracking of metabolites, ions, and biomarkers in sweat using wearable sensors is

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

Advanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

Self‐Supporting Graphene Foam for the Removal of Chlorine from Water

Advanced Materials Interfaces, EarlyView.
Graphene‐based porous materials are promising for sorption and catalysis but often require binders. This study presents a self‐supporting graphene foam made from graphene oxide and hydrazine vapor. Structural, mechanical, and functional analyses confirm its superior chlorine removal efficiency (97%) and reusability, outperforming activated carbon in ...

Surface Coordination and Polymerization of Allyl Mercaptan Passivates the Oxidation of Copper

Advanced Materials Interfaces, EarlyView.
This study demonstrates that allyl mercaptan self‐assembles on the surface of copper via coordination and polymerization, forming an ultrathin polymeric passivation layer (8.06 ± 0.50 nm). The modified copper foil achieves a two‐order‐of‐magnitude anti‐corrosion performance enhancement across multi‐service environments. Abstract The oxidation of copper

Label‐Free Impedimetric Determination of Cortisol Using Gold Nanoparticles Functionalized Laser‐Induced Graphene Interdigitated Electrodes

Advanced Materials Technologies, EarlyView.
Non‐faradaic label‐free impedimetric determination of cortisol is demonstrated with gold nanoparticles (AuNP) functionalized laser‐induced graphene interdigitated electrodes (LIG‐IDE). The AuNP functionalized LIG‐IDE exhibits remarkable characteristics including good logarithmic linear range, high reproducibility, repeatability, and robust selectivity.
