Summary: In this study, a seed-mediated synthesis method for mass production of ultrathin silver nanowires (AgNWs) was reported. The synthesized AgNWs had an average diameter of 17 nm and an aspect ratio of 1000. The method utilized pentatwinned gold dodecahedrons as primitive seeds and Ag nanorods (AgNRs) as secondary seeds. The process eliminated the need for purification and resulted in high purity AgNWs through a simple precipitation process.

Summary: In this study, the dissolution of chitosan-based polyelectrolyte complex (PEC) gels in sodium bicarbonate solutions was systematically analyzed. The results revealed that the reversible conversion of chitosan amine groups to carbamate groups caused the dissolution of the PEC gels. The dissolution rates were influenced by the bicarbonate concentration and the stoichiometric imbalance between chitosan amine and alginate carboxylate groups.

Summary: Metal-quinone networks (MQNs) have been developed as structurally tunable, universally adhesive, hydrophilic, and pH-degradable materials by coordinating metal ions with quinones through metal-acetylacetone coordination bonds. MQNs exhibit bidirectional pH-responsive disassembly and can be assembled into various forms such as particles, tubes, capsules, and films. Leveraging the tunable release ability of MQNs and the medicinal properties of quinones, MQN prodrugs with high drug loading are engineered for anti-cancer therapy and inhibition of the main protease in the SARS-CoV-2 virus.

Summary: The pure phase syntheses of three novel organic charge transfer complexes, obtained by combining triphenylene with TCNQ and its fluorinated derivatives, are reported. The crystal structures of these complexes are determined using 3D electron diffraction. The degree of charge transfer is estimated via examining intramolecular vibrational mode displacements between TCNQF(n) and its complexes with triphenylene using infrared spectroscopy. The direct optical band gaps of the complexes are determined using diffuse reflectance spectroscopy. The study sheds light on compelling charge transfer systems and provides indications for improved electrical organic conductors design.

Summary: The design and construction of synthetic protocells capable of stimuli response and homeostatic regulation is an important challenge for synthetic protobiology. In this study, we demonstrate a reconfigurable model protocell based on osmotic reconfiguration of lipid-coated coacervate droplets into multicompartmentalized coacervate vesicles that can exhibit hypotonic stress-induced volume response and enhance enzyme reactions. The increased nitric oxide (NO) within the swollen vesicles can induce blood vessel vasodilation, showing potential applications in biomedicine, cellular diagnostics, and bioengineering.

Summary: As devices continue to shrink and become more efficient, the synthesis of high-performance materials with precise control has become a major focus. This study demonstrates a template-free, flux-mediated method for producing large quantities of phase-pure, high-temperature superconductor nanowires, including the important quinternary superconductor Bi2Sr2CaCu2O8+x (B2212) for the first time. The findings of this research could potentially lead to further exploration of the physics and chemistry of highly anisotropic superconductor nanowires and their integration into nanoelectronics and energy generation systems.

Summary: Two sol-gel techniques, one based on a natural deep eutectic solvent and the other on a biopolymer-mediated synthesis, were successfully used to synthesize the A(3)M(2)M ' O-6 type materials Na3Ca2BiO6 and Na3Ni2BiO6. Scanning Electron Microscopy analysis revealed a more porous morphology in the material synthesized using the natural deep eutectic solvent method. Both materials exhibited optimal dwell temperature of 800 degrees C, which was found to be a less energy-intensive synthesis process for Na3Ca2BiO6 compared to its solid-state synthesis. Magnetic susceptibility measurements showed weak, temperature independent paramagnetism in Na3Ca2BiO6 and antiferromagnetism with a Neel temperature of 12 K in Na3Ni2BiO6, consistent with previous results.

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.
