Summary: The bimetallic core-shell nanorod SERS substrate nanomaterial (Au NB-DT@Ag NRs) consists of gold nanobipyramids as the inner core and silver-coated nanorods. By modifying with Raman reporter (DT) and varying the amount of silver deposition, the SERS activity of the nanomaterial is improved. The nanomaterial with the best SERS activity can achieve reliable quantitative detection of low concentrations of toxic dyes malachite green and crystal violet.

Summary: This study investigates the effects of confinement potentials, core size, and shell thickness on the confinement of electron, electron-donor atom, and exciton in a cylindrical core/shell/shell quantum dot (CSSQD). The findings suggest that these factors strongly influence the binding energy and energy levels of the particles, which could have implications for modifying electronic and excitonic properties in nanomaterials science.

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.
