Summary: This study introduces a regenerable membrane for the efficient removal of toxic and carcinogenic PAHs from water, utilizing a cavitand receptor in electrospun PAN fibers. The effective uptake/release of PAHs is demonstrated through the design and synthesis of the cavitand receptor BenzoQxCav, with a removal efficiency ranging from 32% to 99%. The membrane's regeneration is achieved by exploiting the pH-driven conformational switching of the cavitand between vase and kite forms.

Summary: The study demonstrates an ene-reductase catalyzed asymmetric hydroalkylation of olefins using alpha-bromoketones as radical precursors, resulting in high levels of enantioselectivity. Radical initiation occurs via ground-state electron transfer from the flavin cofactor located within the enzyme active site. Through multiple rounds of site saturation mutagenesis, a variant of the enzyme capable of catalyzing the desired reaction was obtained, highlighting the utility of ground-state electron transfers in enabling non-natural biocatalytic C-C bond forming reactions.

Summary: Organic cycles are important in chemistry, pharmacology, and material science due to their unique properties. Thioalkynes have attracted increasing attention as a convenient source for constructing organic cycles. This review highlights the construction of organic cycles from thioalkynes, including the synthesis of 2H-azirines, cyclobutanes, and cyclopentenes. Thioalkynes can also be used to synthesize various other cyclic compounds. The review provides an overview of the methods for accessing organic cycles and presents detailed applications of thioalkynes as synthons for preparing organic cycles, with a focus on different types of organic cycles and their corresponding reaction mechanisms if available.

Summary: Efficient and straightforward syntheses of silylthioethers and disulfides have been achieved using novel rhodium complexes as efficient catalysts. These green protocols, utilizing easily accessible reagents and solvent-free conditions, enable the synthesis of compounds containing S-Si and S-S bonds. Preliminary tests have shown promising results for the coupling of mono- and octahydro-substituted spherosilicates with selected thiols, indicating the potential for synthesizing a novel class of functionalized silsesquioxane derivatives.

Summary: Kynurenic acid, a metabolic by-product in humans, has abnormal levels that can indicate diseases. Researchers have developed a water-soluble receptor that can selectively bind kynurenic acid for detection and quantification. Experimental results show high-affinity binding and selectivity for kynurenic acid over tryptophan. The findings have significant implications for sensory recognition of kynurenic acid.

Summary: The study evaluated high refractive index methacrylates as diluents for esthetic bulk-fill composites, showing successful preparation of composites with high depth of cure and excellent esthetic properties. The materials exhibited higher flexural modulus and lower water sorption, with lower shrinkage force compared to TEGDMA-based materials. Methacrylates 1-3 are promising diluents for highly esthetic radiopaque bulk-fill composites.

Summary: This study describes the preparation, dynamic, and assembly characteristics of a vase-shaped basket and its ability to form an inclusion complex with the anticancer drug mitoxantrone. The results of various measurements indicate that the basket can exist as a dimer, in equilibrium with relaxed and squeezed monomers. The basket can include mitoxantrone in its pocket, forming a stable binary complex. The basket shows nontoxic behavior in vitro and a reduced cytotoxicity in the presence of mitoxantrone.

Summary: Four new quinoxaline-spanned cavitands with a diester hydrogen phosphate group were successfully synthesised and applied in catalytic conjugate addition reactions. The study revealed that the catalyst centre surrounded by two trans-positioned quinoxalines significantly influences reaction profile and product distribution, providing a basis for future catalytic cavitand chemistry and artificial enzymatic catalysis.
