Studies on Microcapsules. II. Preparation of Polyphthalamide Microcapsules

Chemical and Pharmaceutical Bulletin, 1969
Polyphthalamide microcapsules were prepared by the interfacial polycondensation reactions between each of 1, 6-hexamethylenediamine and diethylenediamine and each of o-, m-, and p-phthaloyl dichlorides under various conditions. The size and size distribution of the microcapsules formed were determined and the factors affecting them were of studied ...

Surfactant-free, UV-curable core–shell microcapsules in a hydrophilic PDMS microfluidic device

, 2020
We demonstrate a method to create surfactant-free core-shell microcapsules in a hydrophilic polydimethylsiloxane microfluidic device. An ultraviolet light curable polymer was used to encapsulate an oil core.

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 ...
