Influence of Non-Ionic Surfactant and Silver on the Photocatalytic Activity of TiO₂ Films for Degradation of Dyes in Distilled and Tap Water

Applied Sciences
This study describes the impact of surfactant molecular weights (PEG 2000 and PEG 4000) on the photocatalytic activity of TiO2 films, deposited via dip-coating from a PEG-stabilized suspension and silver-functionalized photo-fixation of Ag+ under UV ...

A Material‐Agnostic Strategy for Uniform Patterning of Conjugated Polymers Unveils the True Role of Porosity in Organic Electrochemical Transistors

Advanced Functional Materials, EarlyView.
A generalizable strategy for fabricating regular porous, chemically intact conjugated polymer channels reveals how porosity benefits organic electrochemical transistors. Composition‐dependent performance enhancement is linked to charge carrier mobility, volumetric capacitance, and effective doped volume.

Semiconducting Polymers Post‐Functionalized With Ureido‐Pyrimidinone for Robust Stretchable Transistors

Advanced Functional Materials, EarlyView.
The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable
