Influence of the Substrate Temperature on the Growth Mechanism of Allylamine Plasma Polymer Films

Advanced Materials Interfaces, EarlyView.
The influence of the substrate temperature on the growth mechanism of allylamine plasma polymers is investigated by correlating the plasma chemistry and the physico‐chemical properties of the coatings. New insights about the mechanistic formation of functionalized plasma polymers at a molecular level are provided, paving the way toward a better ...

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

Advanced 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 ...
