Summary: Incorporating cationic additives within inorganic single crystals offers a unique strategy for creating nanocomposites with tailored properties. This approach allows for the successful incorporation of various guest components within the crystals, resulting in nanocomposites with new functional properties. Cationic additives outperform their acidic counterparts in terms of colloidal stability and affinity for crystal surfaces, making them highly effective in a wider range of crystal systems.

Summary: Rapid economic growth has led to increased waste generation in multiple industries, including the automotive sector, due to the lack of established recycling and utilization methods. One particular concern is the large amount of post-consumer tires, which are considered burdensome waste due to the emission of volatile organic compounds (VOCs). To address this issue, novel and environmentally friendly methods for utilizing these tires are needed. One promising approach is shredding the tires to generate ground tire rubber (GTR), which can be used as filler in polymeric materials. This study focuses on the thermomechanical treatment of GTR with zinc borate in a twin-screw extruder to improve its performance in flexible polyurethane (PU) foams. The impact of modification parameters on various properties, including cellular structure, mechanical performance, thermal stability, thermal insulation, and acoustic properties, was investigated. VOC emissions from the fillers and composites were also monitored and evaluated. The results showed that the proposed method of GTR thermomechanical treatment with zinc borate particles can enhance the performance of flexible PU foamed composites and reduce VOC emissions, thus expanding the application range of GTR and providing new ways for its efficient utilization.

Summary: In this study, a novel reconfigured electric double layer (EDL) was constructed using double-charged theanine (TN) additive to improve the electrochemical performance of aqueous zinc metal batteries (AZMBs). The experiments and theoretical computations reveal that TN acts as an anchor to form a water-poor Helmholtz plane onto the zinc anode and coordinates with Zn2+ to tailor the solvation structure in the diffusion layer, resulting in uniform Zn deposition and suppression of water-induced side reactions. This innovative design concept injects fresh vitality into the development of advanced AZMBs.

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: In this study, an efficient Rh(III)-catalyzed selective mono- and dual-C-H bond functionalization/cyclization with iodonium ylide as the sole coupling partner was demonstrated. Fused benzodiazepine skeletons were obtained in excellent yields, providing an improved approach to dual C-H unsymmetrical functionalization.

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.
