Summary: This article presents an alternative method for preparing nitrones using a tetrahedral capsule as a nanoreactor in water. The hydrophobic cavity of the capsule was utilized to reduce reaction times and facilitate the separation of nitrones from the reaction mixture, resulting in comparable yields to existing methods. The method is based on an eco-friendly approach and can be extended to the synthesis of other substrates using various types of macrocyclic hosts commonly used in supramolecular chemistry.

Summary: Carbon dots (CDs) are carbon nanomaterials with great photoluminescent features, low cytotoxicity, and excellent water stability and solubility. In this study, the catalytic performance of VOPO4 in the synthesis of nitrogen-doped carbon dots (N-CDs) was evaluated. The N-CDs obtained showed high photoluminescence due to the presence of oxidized groups on their surfaces, making them potentially useful in photocatalytic degradation.

Summary: A functional and environmentally green procedure was developed for the design of novel pyridine derivatives through two pathways. The first pathway involved a one-pot, four-component reaction under microwave irradiation, resulting in high yields, pure products, short reaction time, and low-cost processing. The second pathway, using traditional refluxing, had lower yields and longer reaction time. The designed compounds were analyzed and evaluated for their in vitro anti-inflammatory activity, with four compounds showing promising results.

Summary: An efficient isocyanide-based synthesis of S-thiocarbamates was developed, allowing direct conversion of N-formamides into thiocarbamates without the need for isolation and purification of the isocyanide component, thus reducing environmental impact and increasing synthesis efficiency. The method was applied to synthesize a library of sixteen thiocarbamates and investigate reaction mechanism, as well as preparing four norbornene-based thiocarbamate monomers for controlled ring-opening metathesis polymerization (ROMP) reactions. The resulting polymers were characterized using size-exclusion chromatography (SEC) and their properties were analyzed with differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA).

Summary: Heterogeneous catalysts, comprised of copper nanoparticles grown on enzyme matrixes immobilized on graphene, were used for the regioselective production of 2,3,4-triacetyl-D-glucopyranose from alpha-peracetylated-glucose in a one-pot parallel process. A synthetic strategy involving the immobilization of lipase on a multi-layer graphene material followed by in situ fabrication of Cu nanoparticles was developed. The resulting solid-phase lipase/metal nanobiohybrids showed high regioselectivity and stability in producing monosaccharide building blocks.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.

Summary: The development of the textile industry has raised concerns due to the contamination of drinking water by organic dyes, which pose a carcinogenic risk to humans. Nanomaterials, particularly semiconductors, have been utilized for photocatalytic degradation of dye pollutants. Various parameters, such as catalyst dosage, irradiation time, light sources, initial dye concentration, temperature, and pH, play significant roles in the degradation process. Different generations of photocatalytic nanomaterials, including single metal nanoparticles, binary and ternary metal oxides, as well as inert solid substrates with photocatalysts, have been employed for dye degradation.
