Summary: In this study, a self-healing and anti-freezing PGS hydrogel electrolyte was prepared by freezing-thawing cycles. The PGS hydrogel showed remarkable self-healing properties and antifreezing properties due to the synergistic enhancement of hydrogen bonds between Gly and PVA. All-in-one supercapacitors (SCS) were assembled using PGS hydrogel as the electrolyte, and exhibited considerable specific capacitance, excellent power density and energy density, remarkable self-healing performance, and outstanding anti-freezing properties.

Summary: Hydrogel-based strain sensors are gaining increasing attention for their flexibility, transparency, and sensitivity. However, their poor environmental adaptability and lack of self-healing have limited their practical value. In this study, a Polyacrylamide / Chitosan / D-Sorbitol (PCS) conductive hydrogel with multiple properties was developed. The PCS hydrogel exhibited high transparency, large fracture strain, excellent toughness, and adhesive ability to various interfaces. It also had a low-temperature crystallization peak and could respond to strain stimuli. The crack in the hydrogel could be fully repaired in a short time. When used as a strain sensor, it accurately monitored and recognized human joint movement and pronunciation signals. This work provides a novel idea for the development of flexible electronics with multi-performance.

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: We report a self-healable and biodegradable hydrogel mulching film (COCu-K) composed of chitosan derivatives, copper-doped carbon dots (Cu-CDs) and KCl for weed inhibition. The dehydrated COCu-K hydrogel fragments can self-heal into an integrated hydrogel film by simple watering, preventing the germination and growth of weeds. The COCu0.08-K2.5 hydrogel shows a degradation rate of 63.61 +/- 3.26% within eight weeks and presents no phytotoxicity.

Summary: Ignited by the concept of bionics, hydrogel-based bionic skin sensors have been widely used in health monitoring, robots, implantable prostheses, and human-machine interfaces. However, there are still challenges to be solved, such as water evaporation and the defects of single conductive mechanism. In this study, a polyvinyl alcohol/polyacrylamide/CaCl2/MXene (PPCM) ionotronics hydrogel was prepared, which showed moisture self-regenerative, highly sensitive, ultra-low temperature anti-freezing, and self-adhesive features. The addition of CaCl2 offered the PPCM hydrogel long-term water retention, ensuring the stability of the hydrogel-based sensor.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
