Toward Pore‐Engineered 3D‐Printed Materials for Sorption Water Harvesting, Interfacial Evaporation, and Radiative Cooling

Advanced Materials, EarlyView.
Water harvesting, radiative cooling, and interfacial solar evaporation are fundamentally governed by coupled heat, mass, and light transport processes. These processes are mediated by pore architecture, including pore size, connectivity, and hierarchical organization.

Inductively Expandable Supraparticles as Microscopic Force Generators for Remote Mechanical Actuation

Advanced Materials, EarlyView.
This study demonstrates the combination of magnetic nanoparticles and functional blowing agents into supraparticles. Upon induction heating, they actuate via rapid gas generation or extensive volume expansion. These supraparticles lift up to 25 000 times their own mass and rapidly open cured epoxy resins, providing a versatile strategy for fast micron ...

Vibration of a Combination of Circular Plates and Cylindrical Shells : 2nd Report, Cylindrical Shells with a Circular Plate in the Intermediate Section

Transactions of the Japan Society of Mechanical Engineers, 1970
The present paper is primarily devoted to the study of the vibrations of a cylindrical shell with a panel or a flange of a circular plate in the intermediate section. Frequencies and displacements are determined by means of minimizing the total Lagrangian.
