Summary: Conductive hydrogels with stretchability, transparency, anti-freezing, self-healing, and adhesion properties are in high demand for intelligent wearable devices. A novel multifunctional organohydrogel based on noncovalent intermolecular interactions was developed by polymerizing hydroxyethyl acrylamide (HEAA) in LiCl cryoprotectant/water solution. The gel formation was driven by hydrogen bonding interactions. The organohydrogel exhibited good conductivity, anti-freezing properties, self-healing, and adhesion due to the composition of LiCl and cryoprotectant. Based on this organohydrogel, a strain sensor for detecting human movements in a wide temperature range was successfully prepared.

Summary: The traditional 2D information storage is limited in capacity and prone to leakage. This study presents a 3D multistage information encryption platform using a bilayer hydrogel with synergistic deformation and fluorescence color change. The bilayer hydrogel can dynamically change its shape and fluorescence properties in response to pH. Information can be encoded on the fluorescent layer and becomes readable only after sequential shape recovery. The information can be further decrypted in stages due to differential fluorescence fading rates. This study provides a novel approach for 3D multistage information encryption with self-erasure capability.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.
