Summary: The synthesis of highly conductive poly(styrene)/poly(aniline) microspheres was explored using poly(styrene-co-methacrylic acid). The copolymer microspheres showed excellent electrical conductivity and potential for manufacturing conductive composites due to their low polymer dispersity index and high zeta-potential. The in-situ polymerization of aniline on the microspheres resulted in a highly conductive disc with superior electrical conductivity and low percolation threshold.

Summary: The ruthenium(II)-catalyzed reaction between aniline derivatives and allylamines was used to synthesize 2-methylindoles via C-H/C-N bond activation. The most effective directing group is the 4,5-dimethyl pyrimidin-2-yl group attached on the nitrogen atom of anilines, while N-allyl-4-fluoro-N-methylaniline is the optimal allylamine. The cyclization products were obtained in yields ranging from 16% to 96%. The reaction does not require an external oxidant, and a possible mechanism is proposed.

Summary: Although PVC is usually produced industrially by emulsion and suspension polymerization, it is rarely used directly as an aqueous polymer dispersion. However, this study shows that it is possible to produce high PVC content latexes with suitable particle morphology and size distribution for direct film formation. Hybrid PVC/acrylic latexes with a core-shell structure are produced by semi-batch emulsion polymerization using a preformed PVC latex as a seed. By using a bimodal particle size distribution, the packing efficiency of the PVC domains is increased, enabling film formation at room temperature with high PVC content.

Summary: In this study, micrometer-sized block copolymer particles were successfully synthesized using iodine transfer polymerization as a first attempt. Methyl methacrylate (MMA) and vinyl acetate (VAc) were used as the hydrophilic monomers in a microsuspension system. The resulting poly(methyl methacrylate)-block-poly(vinyl acetate) (PMMA-b-PVAc) particles exhibited the desired molecular weight and relatively narrow molecular weight distribution, despite the low degree of polymerization of the PVAc block. The hydrolysis of these particles resulted in three different morphologies, and the formation mechanism of each morphology was proposed, attributing it to the interaction between the iodic ions generated from the degradation of iodine end groups and the elongated poly(vinyl alcohol) (PVA) segments derived from PVAc.

Summary: A novel electrochemical strategy using gold nanoparticles decorated on polyethyleneimine-modified iron oxide nanoparticles (Fe3O4-PEI-Au) as a nanocomposite modifier was presented for sensitive and selective detection of Cd(II). The aptasensor was fabricated by immobilizing a thiol-terminated Cd(II) aptamer onto a screen-printed carbon electrode modified with the Fe3O4-PEI-Au nanocomposite, which provided enhanced aptamer loading, biocompatibility, and conductivity. Differential pulse voltammetry was used for quantitative measurement of Cd(II), showing a dynamic linear detection range from 0.04 nM to 25 nM and a limit of detection of 0.01 nM, surpassing the safe limit in drinking water. The label-free aptasensor exhibited high selectivity, reproducibility, stability, and reliability for real-time Cd(II) monitoring in environmental water samples.

Summary: For the first time, a dispersive micro-solid phase extraction (D-mu SPE) based on graphene oxide was used for the ultrasensitive determination of Cd. With this method, Cd can be efficiently extracted from a mixture of alkali and alkaline earth metals without the need for an elution step. The combination of D-mu SPE and SAGD OES significantly reduces matrix effects and improves the tolerance of Cd to alkali metals. The method shows simplicity in the measurement system and the commercially available nanosorbent used.

Summary: This work proposes a rapid and sensitive spectroscopic method for detecting melamine in food products using rare-earth Terbium-doped Graphene Quantum Dots (Tb-GQDs) synthesized by microwave and simple chemical conjugation methods. The synthesized Tb-GQDs show a spherical shape with a size of approximately 6 nm and a quantum yield of 52%. The maximum detection limit for melamine concentration in milk and milk products is found to be 0.31 μM. The dual emitting Tb-GQDs provide a sensitive and effective platform for real-time detection of melamine in food samples, particularly in milk, and show promising potential in the food industry.
