Summary: Supramolecular hydrogels are attractive biomaterials due to their dynamic reversibility, self-healing, and excellent biocompatibility. However, the contradiction between non-covalent interactions and mechanical strength poses a great challenge for their practical application. This review discusses strategies for enhancing the mechanical strength of supramolecular hydrogels and explores their applications in flexible electronic sensors, wound dressings, and 3D scaffolds.

Summary: The solid-state properties of supramolecular polymers based on metal-ligand complexes are significantly influenced by the choice of ligand and metal salt. Different components can be used to modify various properties of the polymers. The study presents metallosupramolecular polymers based on a bidentate ligand, which can form coordination complexes with transition metal ions. The polymers exhibit microphase separation and different morphologies depending on the metal ion and thermal history, along with the ability to heal defects and UV-light responsiveness.

Summary: The combination of solution self-assembly and solid self-assembly can produce novel functional materials that cannot be obtained individually. In this study, two-dimensional platelets with controllable morphologies were formed via the living self-assembly of a donor-acceptor fluorophore and volatile coformer in solution phase. After high-temperature annealing, new heat-resistant platelets with high two-photon absorption cross sections were obtained.

Summary: Uniform two-dimensional platelets with tailorable shapes and controlled sizes are successfully constructed by creating new nuclei from a donor-acceptor molecule and 1-hexanol in this study. The growth of these platelets can be regulated by simply varying the amount of 1-hexanol, and complex concentric multiblock 2D heteroplatelets can be obtained by sequential and alternative addition of different donor-acceptor molecules. These platelets exhibit enhanced photostability compared to those obtained by conventional self-assembly without 1-hexanol involvement.

Summary: The separation of specific ions in water is essential for the recovery and reuse of metals and nutrients, but current membrane technologies lack the required precision selectivity for a circular resource economy. This study investigates whether the cation/cation selectivity of a composite cation-exchange membrane (CEM) is affected by the mass transfer resistance of the underlying CEM. The results show that eliminating resistance from the base layer of the CEM can significantly increase selectivity, highlighting the importance of low-resistance CEMs for precise separations with composite membranes.

Summary: Developing highly efficient bifunctional oxygen electrocatalysts is crucial for zinc-air flow batteries. Metal-organic frameworks (MOFs) and covalent organic polymers (COPs) have emerged as promising alternatives due to their designable and controllable atomic-level structures. However, their catalytic performances are limited by conductivity and catalytic activity. In this study, nanosheet FeNi-MOF and iron phthalocyanine rich COP hybrid materials are assembled through the pi-pi stacking effect to create highly efficient bifunctional electrocatalysts. The resulting catalyst exhibits superior catalytic performance and stability, making it a promising candidate for zinc-air flow batteries.

Summary: In this study, we modified the electrolyte cubic plus association equation of state (e-CPA EoS) and integrated it with two electrical conductivity models to estimate the electrical conductivity of 11 monovalent electrolyte solutions in water. The modified e-CPA model demonstrated better performance and the hybridization with electrical conductivity models resulted in two predictive models for estimating the electrical conduction of dilute and concentrated electrolyte solutions. These predictive models showed relative average percentage deviations (AARD) of 11.15% and 13.87% over wide ranges of temperature and electrolyte concentration.
