Summary: 2D materials can be functionalised with ionisable functional groups to form 2D electrolytes. In this study, heterostructures were formed by self-assembly of functionalised graphene oxide (GO) with cationic groups and molybdenum disulfide (MoS2) with anionic groups. The application of sonication allowed the continuous assembly of the 2D materials into heterostructured nanofibers, which resemble naturally occurring polyelectrolytes. This method offers a facile approach for the continuous processing of low-cost heterostructured nanofibers with potential applications in various fields.

Summary: This study fabricated hydrocarbon (n-eicosane)-loaded poly(ethylene oxide)/poly(methyl methacrylate) (PEO/PMMA) blended fibers with bead-free and beaded morphologies using the electrospinning technique. Their morphological characteristics were determined by SEM, while their chemical composition and structural properties were examined by FTIR and XRD spectroscopy. TGA and DSC were implemented for obtaining information on the materials' thermal properties. The heating-cooling cycles revealed that the melting temperature increases with increasing n-eicosane content in both sample series, and the second crystallization peak increased upon increasing the n-eicosane content. All investigated materials exhibited excellent repeatability with low supercooling and high enthalpy values. Interestingly, both series were found to be suitable as phase change materials for a wide range of n-eicosane content values.

Summary: Silver nanowires with varying diameters and submillimeter lengths were obtained by changing a reducing agent during hydrothermal synthesis. Control over the nanowire diameter is critical in determining their plasmonic properties, affecting fluorescence enhancement and surface plasmon polariton propagation. Larger diameter nanowires show longer propagation lengths but reduced fluorescence enhancement, indicating ways to control plasmon excitations by tuning their morphology.

Summary: Bacterial infection poses a major threat to global human health, and the development of antibacterial materials has been highly emphasized. In this study, zinc oxide nanoparticles (ZnONPs) were successfully loaded onto amino cellulose fibers (ACFs) through the Schiff-base structure. The resulting ZnONPs@ACFs composite materials exhibited uniform dispersion and maintained intact morphology. Under the optimized conditions, the ZnONPs@ACFs demonstrated a zero-span tensile strength of 66.48 N/cm, making them suitable for the production of antibacterial sheet materials through the wet-forming process. The composites showed inhibition zones of 4.95 mm and 1.10 mm against E. coli and S. aureus, respectively, suggesting their potential applications in food packaging and biological medicine.

Summary: DNA-modified nanoparticles are important in nanomedicine for DNA sensing, therapeutics, and self-assembly. Conjugating DNA to nanoparticle surfaces is limited and inefficient, but we demonstrate a new approach using electrostatic attraction between DNA tiles and nanoparticles. This approach allows control over DNA presentation and was successfully demonstrated using various nanoparticles. The versatility of this electrostatic DNA caging approach enables further applications in medicine and materials science.

Summary: A fast route for the design of nanohybrid structures is reported, where a fibrous network of polycaprolactone (PCL) is wrapped with graphene oxide (GO) sheets and carbon nanotube (CNT) brushes. The method involves electrospinning PCL solutions onto a suspension of GO and CNTs in ethanol, leading to the self-assembly of hierarchical structures. The resulting lightweight and robust amphiphilic monoliths demonstrate high efficiency in removing pollutants from water.

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.
