Summary: In this study, a novel swelling induced enhanced hydrogel with underwater sensing properties was reported. The nanocomposite hydrogel, consisting of two acidic comonomers AA and AMPS in the presence of acidic Al(OH)3 NPs aqueous solution, exhibits weak coordination crosslinking initially but becomes strongly crosslinked after water immersion. This enhanced hydrogel can sense human motions in air and underwater, even detecting subtle motions like pulse beating in the aqueous solution. Thus, it has potential applications in the field of biomedical robots and biosensors in aquatic environment.

Summary: Excessive vibration can lead to structural damage or harmful noise. Different vibration control strategies, such as active, passive, and semi-active types, provide stable and efficient solutions for vibration control. However, conventional damping structures face challenges in meeting wide frequency range and high precision damping requirements. By studying bionic damping and vibration control strategies, more efficient damping structures can be designed.

Summary: In recent years, there has been an increase in the proposal of passive radiative cooling materials, with a focus on silica (SiO2) due to its stability, non-toxicity, and availability. However, the bulk phonon-polariton band of SiO2 results in a reflection peak within the atmospheric transparency window, leading to a decrease in emissivity and posing a challenge for achieving sub-ambient passive radiative cooling. Therefore, the latest developments in this field aim to design engineered SiO2 photonic structures to enhance the cooling potential of SiO2 radiative coolers.
