Summary: The crown ether 18-crown-6 has the potential to suppress fibrillation in lysozyme and decrease the protein's β-sheet content, thus inhibiting the formation of amyloid fibrils. These findings can be utilized to develop more effective anti-amyloidogenic agents.

Summary: Effective separation and recovery of chemically similar transplutonium elements from adjacent actinides is challenging in spent fuel reprocessing. In this study, the coordination mechanism between transplutonium elements and crown ether macrocyclic ligands was systematically investigated. The results provide theoretical clues for the design and development of macrocycle ligands for the in-group separation of transplutonium elements.

Summary: A synthetically minimal artificial emulsion platform has been designed in this study, capable of autonomously adapting to its chemical environment through interfacial supramolecular recognition events. The platform demonstrates programmed up- and down-regulating capabilities by selectively assembling synthesized crown ether surfactants onto anisotropic biphasic emulsion droplets. This adaptive soft material platform showcases utility in self-regulated uptake and release of metal ions, biomimetic recognition of biomolecules, and triggered surface-encoded payload release applications.

Summary: The study introduces a photochromic supramolecular complex with benzopyran and a fluorescent compound, demonstrating that the presence of the fluorophore can significantly increase the bleaching rate compared to free benzopyran at room temperature. Varying the components in the supramolecular complex is preferable for obtaining desired characteristics in the system.

Summary: Diffusion-ordered spectroscopy (DOSY) is an efficient technique for analyzing complex mixtures, but often struggles to separate positional isomers. The use of 18C6 and 18C6/K+ complex as matrices can effectively discriminate and identify positional isomeric mixtures, demonstrating superior performance in interacting with different components.

Summary: The study presented the synthesis, crystal structure, spectroscopic analyses, and theoretical calculations of the first trivalent plutonium crown ether inclusion complex Pu-III-18C6. It was found that the plutonium atom is completely encapsulated within the cavity of the 18-crown-6, forming a distorted geometric structure, with weak Pu-O dative bond confirmed by theoretical evaluation. This work may enhance the understanding of host-guest interactions between trivalent transuranic elements and macrocyclic ligands.

Summary: The actinide lanthanide separation (ALSEP) process is a method used to separate americium and curium from lanthanide fission products, reducing the radioactivity and heat loading of nuclear waste. This process utilizes HEDTA as the primary ligand to selectively strip the actinides while leaving the lanthanides behind. A new ternary lanthanide-HEDTA-citrate complex was discovered during experiments.

Summary: RNA regulation can be achieved by a second targeting RNA molecule, and SHAPE can be used to study the structure of RNA molecules and resolve RNA:protein interactions. In this study, SHAPE is applied to investigate RNA-mediated binding processes in RNA:RNA and RNA:RNA-RBP complexes. The results reveal the importance of seed and compensatory region interactions in the binding of microRNA to mRNA targets, providing complementary evidence for luciferase-assay-based evaluation.

Summary: Based on the momentum matching theory, a room-temperature crown ether based switchable dielectric material has been successfully designed, showing a higher phase transition temperature and great potential for bistable dielectric switches at room temperature. This work opens up new possibilities for the development of crown ether inclusion complex dielectric switches for various applications.

Summary: We demonstrate a method called Spectrally selective Time-resolved Emission through Fourier-filtering (STEF) for separating and resolving the dynamics of multiple emitters without using conventional filters. Our approach utilizes a fixed path-length imbalanced Mach-Zehnder interferometer to interfere and cancel (or enhance) specific spectral signatures corresponding to one emissive species. We show the range and utility of STEF by performing various procedures, including filtering laser scatter, separating fluorescence lifetimes, and resolving overlapping fluorescent stains.

Summary: Supramolecular asymmetric catalysis is an important field that combines supramolecular chemistry and asymmetric catalysis. By utilizing crown ether-based host-guest chemistry and chiral phosphoric acid, the catalytic reaction can be regulated, leading to improved yield and enantioselectivity of the catalyst.

Summary: Menstrual blood (MB) is a significant forensic evidence, consisting of peripheral blood, vaginal fluid, and endometrial cells. Understanding the changes and biochemical analysis of menstrual blood using fluorescence spectroscopy can help differentiate the cause of blood presence in forensic investigations, whether it is due to assault or a natural cause. The mechanism of fluorescence changes in menstrual blood involves the kinetic transformation of three fluorophores: tryptophan, nicotinamide adenine dinucleotide, and flavins.

Summary: In this study, a powerful separator was developed by filling the interior of a poly-propylene separator with self-assembled supramolecules. This separator overcomes the limitations of lithium polysulfide shuttling and improves the selectivity of lithium ions. By optimizing the sulfur redox kinetics, the proposed separator inhibits LiPS shuttling, enhances Li-ion transport, and promotes highly efficient and durable Li-S batteries.
