Summary: A facile method for synthesizing highly monodisperse single-crystalline gold nanoparticles (Au NPs) using universal seeds has been reported. The single crystallinity of particles is achieved by oxidative etching and controlled surface capping by silver atoms. The resulting Au NPs show uniform single crystallinity, high shape yield, and low size polydispersity, demonstrating the importance of seed uniformity in the synthesis process.

Summary: This study uses molecular dynamics simulations to investigate the mechanical properties of crystalline alpha quartz. The results show that crystalline quartz exhibits anisotropic behavior under applied load, with varying Young's modulus in different directions. Central cracks decrease average stress and strain, and the strain rate affects the stress-strain behavior of the models, although it becomes negligible as the central crack length extends.

Summary: Vanadium pentoxide (V2O5) nanospheres were synthesized hydrothermally for the first time with high specific surface area, investigating the effect of different parameters on precipitate yield. Various drying methods and auxiliary processes were employed to improve drying process and reduce nanoparticles aggregation, leading to successful production of V2O5 nanospheres with average diameter of 37 nm. The application of synthesized NPs showed higher conversion rate for H2S elimination from sour water compared to commercial V2O5 powder.

Summary: Monodisperse hollow mesoporous silica nanospheres with large cavity (62 nm) in the inner core, small mesopores in the outer shell, and high specific surface area of 373 m(2)/g are successfully synthesized via dual-template synthetic approach. The volume proportion of alcohols in the solution can effectively regulate the architectures of the nanospheres. The prepared hollow mesoporous silica nanospheres demonstrate high loading capacity and favorable selectivity towards anionic dye molecules.

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.
