Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

Advanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Elastomeric 3D‐Printed Microenvironments Enable Nanonewton Force Measurements in Healthy and Diseased Human Pluripotent Stem Cell‐Derived Neuroepithelial Cells

Advanced Materials, EarlyView.
We present elastomeric three‐dimensional (3D) microstructures fabricated via two‐photon polymerization (2PP) and post‐processed through wet etching, for quantifying nanonewton (nN)‐scale forces applied by healthy and diseased neural cells. The mechanically characterized free‐standing beam architectures enable measurement of traction forces of ...

Electropolymerized Aptasensor for Femtogram‐Level Cytokine Detection

Advanced Materials, EarlyView.
Electropolymerization of 3‐amino‐ʟ‐tyrosine creates ultrathin, smooth, and chemically robust pALT nanofilms with accessible carboxyl functionalities for direct aptamer immobilization. Integrated with fiber‐optic SPR and OECT platforms, these interfaces enable IL‐6 detection down to 100 fg mL−1 and provide a versatile route to bioelectronic sensing ...

Anatomical Locking Plate with Additional K-wire Fixation for Distal Clavicle Fracture

, 2017
Background: Neer type II distal clavicle fractures have the drawback of coracoclavicular instability and insufficient distal bony fragment, thereby making it difficult to achieve adequate fixation. Although various surgical treatments have been described
