Summary: This study focuses on the photocatalytic removal of toxic and persistent MB dye from aqueous solution. The S/AuNPs photocatalyst was synthesized by the sol-gel method and showed high thermal stability. The encapsulated AuNPs within the silica shell exhibited a reduced particle size and increased E-g value, resulting in a large surface area for improved photocatalytic activity. After 210 minutes of UV radiation, the S/AuNPs demonstrated effective degradation of MB with a rate constant of 0.01 min(-1).

Summary: Non-crystalline nanostructured silica core - alumina rich shell microspheres with Gd ions in the shell were synthesized using a sol-gel procedure based on the Stober method. The effect of increasing Gd ions content on the local structure in alumina rich shell and at its interface with silica core was investigated. The results showed that the concentration of paramagnetic ions influenced the local magnetic field and promoted the diffusion of aluminum in the silica network and the migration of silicon in the alumina rich shell. This led to the formation of stable non-crystalline structures with Gd ions on the external layer of the shell, which could potentially be used as contrast agents for MRI.

Summary: In this study, core/shell ZnO/TiO2 nanocomposite samples were prepared using the sol-gel method at different time spans. The sample prepared in the 15-minute time span (ZnTi15) exhibited the highest photocatalytic activity and charge carrier density, making it the optimal sample. The formation of a heterojunction at the ZnO/TiO2 interface could be attributed to the increased photocurrent density observed for the ZnTi15 sample.

Summary: By preparing mesoporous shell/core silica abrasives and developing a novel green CMP slurry, polishing performance can be improved and environmental pollution can be reduced. Molecular dynamics simulations show that the mesoporous structure inhibits the formation of convex peaks and promotes uniform distribution and removal of surface atoms, leading to enhanced polishing results.

Summary: Lignin-silica hybrid nanocomposite films were prepared on aluminum alloys 2024 through a sustainable dip-coating process combined to an evaporation-induced self-assembly methodology. The NDR synthesis involved a pre-coating functionalization of the substrate by a linker, which provides a significant improvement and enhancement of the film stability. The hydrophobic behavior of the hybrid film coating was improved by the self-assembly of lignin nanoparticles on the surface.

Summary: In this article, a novel catalytic reaction using Pd(0) and Bronsted acid is reported for the synthesis of biologically important imidazolidinone-fused N-heterocycles through redox-neutral intramolecular N-allylation of indoles and pyrroles with alkynes. This atom-economical method is applicable to a wide range of substrates and eliminates the need for leaving groups or oxidizing agents commonly used in traditional allylation reactions.

Summary: This study presents the design and synthesis of sulfated disaccharide inhibitors based on IdoA(2S)-GlcNS(6S), which showed potent inhibition of Sulf-2. The results suggest that IdoA(2S)-GlcNS(6S) is the shortest fragment size required for effective inhibition of Sulfs, and a trisulfated disaccharide is identified as the minimal fragment size of heparan sulfate for effective endosulfatase inhibition.

Summary: The self-adaptability of galvanostatic electrolysis was found to be helpful in a multistage chemo- and diastereoselective electrochemically promoted cyclodimerization of chalcones. Through a series of reductive events, densely functionalized cyclopentanes with five contiguous stereocenters were obtained (25 examples, yields up to 95%, dr values up to >20:1). Further experimental and electrochemical investigations indicated the crucial role of dynamic kinetic resolution of the aldol intermediate in the reaction mechanism.

Summary: In this study, the synthesis of functionalized benzo[a]phenazines and indazolo[2,3-a]quinolines was achieved through Rh(III)-catalyzed oxidative annulation of 2-arylquinoxalines and 2-aryl-2H-indazoles with allyl alcohols. The method showed a wide substrate scope, excellent functional group tolerance, good to high yields of annulated products, and the capability for scaled-up synthesis. A tentative mechanism of the annulation reaction was proposed based on a preliminary mechanistic investigation.
