Summary: The anionic wormlike micelles prepared from amino acid surfactant show multiple pH and temperature responses. By adjusting the pH value, the micellar solution can reversibly transform between a low-viscosity emulsion and a viscoelastic fluid. The viscosity of the solution changes reversibly with pH and the gel temperature increases with pH.

Summary: This study synthesized and characterized novel hydrazonotriazole analogues with different hydrophobic alkoxy units. The alkyl-substituted naphthalene-type hydrazonotriazoles acted as pH sensitive and thermoreversible organogelators. They were prepared by aldol condensation and exhibited gelation properties in various solvents with a sol-gel reversible response to pH changes and colorimetric change. The optimal gelation was observed in the nonyl-substituted hydrazone with thermal stability up to 58°C.

Summary: Self-assembled peptides are a promising family of biomaterials that can be used for various biomedical applications. This study introduces a simple yet effective approach to construct pH-responsive peptide assemblies by incorporating unnatural ionic amino acids with aliphatic tertiary amine side chains. Through experimental and computational investigations, the researchers demonstrate that these residues can be incorporated and stabilized within the hydrophobic compartment of the peptide assembly, resulting in a shift of their pKa values to a biologically relevant pH range. The pH-induced ionization and its effect on the assembly's biological activity are thoroughly analyzed. This approach allows for the tuning of pH responsiveness across a wide pH range in complex biological environments, making it highly valuable for applications such as targeted therapeutic delivery and proton transport.

Summary: The rampant use of antibiotics and emergence of zoonotic diseases have led to serious global health hazards. Fungal infections, particularly those caused by Aspergillus species, are challenging due to their eukaryotic nature. Researchers have developed pH responsive cationic biocompatible polymers based on amino acids inspired by antimicrobial peptides, which have demonstrated effective fungicidal activities against Aspergillus niger. The mechanism of action involves inhibition of hyphal growth and distortion of conidiophores, with the aqueous solution properties of the side chain groups of individual amino acids significantly influencing the fungicidal activities.

Summary: The challenges of poor printability and low printing accuracy in hyaluronic acid-based bioinks for extrusion-based 3D bioprinting are tackled by developing a bioink consisting of gallic acid-functionalized hyaluronic acid (HAGA) and hyaluronic acid methacrylate (HAMA). The blend's HAGA component enables viscosity modulation, resulting in improved injectability and printability. Postprinting, the HAMA component is photocrosslinked to create a hydrogel with both HAGA and HAMA networks, showing sufficient printing quality and accuracy. The bioink also has enhanced viscoelastic properties, tissue adhesion, and antioxidant activity.

Summary: In this study, a photo-responsive organogel made from low molecular mass gelators (LMOGs) of stilbenedicarboxylic acid (St) and octadecylamine (NC18) was described. Organogels were formed by the mixture of St and NC18 in various organic solvents, forming ion pairs via electrostatic interaction. The phase transition temperature of the St(NC18)2 gel increased with the increase of gel agent concentration, reaching a constant value of 369 K at a concentration of 90 mmol/L. The organogels could be destroyed by UV irradiation due to the photo-responsive characteristics of the stilbene group. Compared to traditional responsive LMOGs, the St(NC18)2 gel system is composed of readily available compounds, making it suitable for a wider range of applications in the development of smart materials for sensors, recognition, and separation.

Summary: Research into hydrogen-bonded organic frameworks (HOFs) and especially metal hydrogen-bonded organic frameworks (M-HOFs) is still in its infancy. The use of Kuratowski coordination units has advanced this field by synthesizing and characterizing a novel series of M-HOFs. These frameworks are stabilized via a unique hydrogen bond framework between amine functional groups and a central halogen anion, resulting in important additions to the subclass of permanently porous M-HOFs.

Summary: Porosity and surface area analysis are important in modern materials science. However, there is a lack of attention to the reproducibility issue in calculating BET surface areas from identical isotherms, raising concerns over the reliability of reported BET areas. To address this, a new computational approach called BET surface identification (BETSI) has been developed for accurately and systematically determining the BET area of nanoporous materials.

Summary: Atomically precise nanoclusters (NCs) have been used for constructing self-assembled multifunctional superstructures, however, long-range reversible self-assembly based on dynamic covalent chemistry on the NC surface has not been explored yet. In this study, Au-25 NCs containing thiolated umbelliferone ligands were used to achieve self-assembly and inter-toroidal reaction, resulting in macroscopic supertoroidal honeycomb frameworks. The study also demonstrated a photo-controlled drug release system using a cross-photocycloaddition reaction between coumarin-tethered NCs and an anticancer drug.

Summary: Supramolecular host-guest complexes are dynamic systems consisting of macrocyclic host molecules encapsulating smaller guest molecules, and can be used to tackle fluorescence quenching and photobleaching. This study demonstrates the application of supramolecular host-guest complexation in a hydrogel network to create tunable hydrogel-based lasers. By doping hydrogel with cucurbit[7]uril as a host molecule, the fluorescent quantum yield and photostability of Rhodamine B molecules in the hydrogel are significantly improved. A thin-film distributed feedback hydrogel laser with wavelength tunability is fabricated to showcase the concept. These findings, combined with the stimuli-response of hydrogels, open up possibilities for affordable and small-scale photonic devices for sensing applications.

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 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.
