Pierceable, Water‐Resistant, and Transparent Nanofilm Electrodes Comprising Carbon Nanotubes for Long‐Term Monitoring of Plant Electrophysiology

open access: yesAdvanced Science, EarlyView.
Ultra‐flexible electrodes composed of single‐walled carbon nanotubes on a polymeric substrate exhibit excellent transparency, water resistance, and conformability to hairy surfaces. These non‐invasive nanofilms are easily pierced by trichomes, overcoming the structural barriers in plant electrophysiology.

Paradigm shift in wearable bioelectronics: Drift‐free organic field‐effect transistor biosensors enabled by diode‐connected pairs

open access: yesBMEMat, EarlyView.
Organic field‐effect transistor (OFET)‐based biosensors are promising for wearable technology due to their flexibility and low cost, but their susceptibility to signal drift from mechanical stress and environmental factors remains a challenge. Here, we highlight a novel strategy that eliminates these drifts through a fundamental redesign of the OFET ...

Gold Nanoparticles Supported on Poly(Phenylene Oxide) as Selective and Versatile Catalyst for Hydroamination of Arylacetylenes with Anilines

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
Gold nanoparticles supported on poly(2,6‐dimethyl‐1,4‐phenylene oxide) (AuNPs‐PPO) demonstrates efficient and selective hydroamination, with performance tuned by reaction conditions and substrate design. Electron‐withdrawing substituents enhance conversion while preserving E‐imine selectivity, highlighting a key role of intermediate acidity.

Diffusion Coefficients of Organic Compounds in Molten High‐Impact Polystyrene

open access: yesPolymer Engineering &Science, EarlyView.
Schematic overview of the determination of diffusion coefficients in molten high‐impact polystyrene. ABSTRACT Polystyrene (PS) is a widely used packaging material, but its recycling for food‐contact applications is still limited, partly due to a lack of quantitative data on the migration behavior of potential contaminants.
