Rubber‐Glass‐Crystal Triple Phase Transition in Polyacrylamide Hydrogels and Environment‐Adaptive Shape Memory Effect

Advanced Materials Interfaces, EarlyView.
By analyzing the thermal‐mechanical properties and molecular‐scale interactions in polyacrylamide (PAAM) hydrogels, this research demonstrates a rubber‐glass‐crystal phase transition under the combined stimuli of temperature and moisture. Because of these hybrid phase transitions, PAAM hydrogels exhibit shape memory behavior in thermal and moist ...

A Self‐Cleaning Solar Evaporator Based on MXene/Aramid Nanofiber Aerogels for Efficient Water Desalination

Advanced Materials Interfaces, EarlyView.
This study develops a self‐cleaning solar evaporator based on MXene‐coated aramid nanofiber aerogels for efficient desalination under high‐salinity conditions. The cylindrical evaporator combines strong photothermal conversion, capillary water transport, and self‐rotation triggered by salt accumulation.

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

3D SAR Image Background Separation Based on Seeded Region Growing [PDF]

IEEE Access, 2019
The environmental interference and the noise in 3D synthetic aperture radar (SAR) image, considered as the background, are inescapable and ought to be eliminated. For 3D SAR image, there is a spatial separation of the target and the background. Therefore, it is possible to achieve the separation of the target and the background by image segmentation ...
