Economic Low‐Carbon Chemical Production via Paired Electrolysis of Carbon Monoxide (CO) and 5‐hydroxymethylfurfural (HMF)

open access: yesAdvanced Materials, EarlyView.
Replacing CO2 with CO at the cathode and integrating a catholyte‐layer membrane electrode assembly transforms paired electrolysis into a stable platform for co‐producing ethylene and 2,5‐furandicarboxylic acid. Combined experimental and techno‐economic analyses identify carbon monoxide and 5‐hydroxymethylfurfural as the most compatible pairing ...

Transducers Across Scales and Frequencies: A System‐Level Framework for Multiphysics Integration and Co‐Design

open access: yesAdvanced Materials Technologies, EarlyView.
Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
