Summary: Zwitterionic polymer materials have been extensively studied, but zwitterionic peptides supramolecular hydrogel materials are rarely studied. In this study, the preparation of two zwitterionic hydrogels using self-assembled peptides were reported. The differences in structure and function of the zwitterion peptide hydrogels caused by the two preparation methods were compared, with the enzyme induced self-assembly method showing better solubility and lower cytotoxicity.

Summary: This study proposes a non-Euclidean geometry model to understand the chemo-mechanical coupling in self-assembled triblock polymers, based on the thermodynamics of microphase separation. The model characterizes the topologies of self-assembled and cross-linked networks using geometric parameters formulated from the non-Euclidean geometry equation. The effectiveness of the model is verified through finite-element analysis and experimental results. This study provides a new geometrical approach to understand the mechanochemistry and thermodynamics of self-assembled block polymers.

Summary: Supercapacitors based on two-dimensional MXene (Ti3C2Tz) exhibit excellent performance in ultrathin electrodes with low mass loading, but face limitations in high-rate performance and restacking of nanosheets. In this study, a vertically aligned MXene hydrogel composite was designed using thermal-assisted self-assembled gelation, providing enhanced electron transport and rapid ion transport. The resulting hydrogel electrode showed excellent performance in both aqueous and organic electrolytes, with high capacitance, stability, and high-rate capability for up to 300 μm thick electrodes, representing a significant step towards practical applications.

Summary: This study investigates the impact of covalent modification on the self-assembly of a quinonoid zwitterion derivative. It is found that covalent modification can induce the formation of self-assembled structures at low concentrations, where no self-assembly behavior is observed on the bare surface. The size of the self-assembled domains decreases with increasing the density of grafted molecules, and the dynamics of domains, including growth, shrinkage, and orientation conversion, are captured with molecular resolution.

Summary: Lipids play a crucial role in regulating bodily functions and providing energy, primarily entering the body as triglycerides through diet. Certain lipids have been found to promote the formation of highly ordered colloidal structures during gastrointestinal digestion, impacting nutrient absorption. This process has implications for drug delivery, enabling the solubilization of poorly water-soluble drugs in the gut for absorption.

Summary: A wireless localized stimulator composed of a piezo implant with high piezoelectric output has been developed as an anti-infective therapy patch to modulate the electro-microenvironment of biofilm around GI wounds for effective inhibition of bacterial infection when combined with ultrasound treatment. The piezo implant generates pulsed charges in response to ultrasound stimulation, which destroys the macromolecular components of bacterial biofilms and inhibits bacterial proliferation. The combination of the piezo implant and ultrasound stimulation also exhibits successful in vivo anti-infection efficacy in a rat model.

Summary: This study focuses on the structure design of high-temperature electrothermal composites, using two types of high-density polyethylene-based composites filled with multi-walled carbon nanotubes as examples. The relationship between the molecular weight of the matrix and the electrothermal properties of the composites is investigated through the changes in microstructure and conductive network during heating-cooling cycles. The high molecular weight component in the composites contributes to improved electrothermal stability and repeatability, making them suitable for high-temperature electrical heating applications.

Summary: Helix-fiber composites (HFCs) are used in intelligent stretchable materials or devices by wrapping a flexible core. The mechanical coupling between the core and wrapping plays a critical role in controlling the structure and mechanical properties of HFCs. The results show that the mechanical properties of HFCs can be programmed by adjusting the mechanical coupling strength, and they also exhibit unique pseudo-elastic behavior. Additionally, HFCs can function as an elastic conductor, sensor, and elastic mold for structure transplantation by decoupling the elastomer core from the helix fiber.

Summary: Thermal management technologies are important for maintaining stable working temperature for electronics. Organic solid-liquid phase change materials (PCMs) are widely used due to their high energy storage capacity and stable properties. However, achieving good flexibility, high thermal conductivity and complete leakage resistance simultaneously is still a challenge for organic PCMs. This study introduces boron nitride (BN) pre-attached to the surface of paraffin wax microcapsules (MCPW) and compounded with natural rubber (NR) to form flexible composite PCMs with thermally conductive pathways constructed by BN. The obtained flexible composite PCMs exhibit impressive balance in shape stability, energy storage density, mechanical flexibility, and thermal conductivity, showing great potential for thermal management of electronics.

Summary: To overcome the limitations of polylactide (PLA) in terms of melt strength, processability, and brittleness, researchers have developed PLA covalent adaptive networks (CANs) with biobased epoxidized soybean oil (ESO) as dynamic crosslinks. By incorporating maleic anhydride (MA) and using Zn2+-catalyzed transesterification exchange, PLA CANs with enhanced melt strength and toughness were successfully produced. The resulting PLA CAN films show promising properties, including high elongation at break and lower environmental impacts compared to petroleum-based plastic films.
