Summary: In this study, the preparation of polystyrene-block-poly((3-chloro-2-hydroxypropyl methacrylate)-co-(4-methoxymethylstyrene)) (PS-b-P(ClHPMA-co-MMS)) and polystyrene-block-poly((3-chloro-2-hydroxypropyl methacrylate)-co-(4-methoxymethylstyrene)-co-(3-(1-mesityl-1H-imidazolium-3-yl chloride)-2-hydroxypropyl methacrylate)) (PS-b-P(ClHPMA-co-MMS-co-MesIHPMA)) block copolymers and their micelles in methanol were reported. The polymerization behavior of ClHPMA and its copolymerization with styrenic comonomers were studied using nitroxide-mediated polymerization (NMP). The block copolymers were functionalized by nucleophilic substitution and their micellization was achieved through solvent exchange. The morphology of the nanoaggregates was influenced by the preparation pathway and the composition of the block copolymers, as confirmed by dynamic light scattering (DLS) and transmission electron microscopy (TEM).

Summary: In this study, a novel method for the preparation of freestanding graphite nanoplatelets (GNP) was developed using dry ball-milling. The results showed that the freestanding GNP, with selective edge functionalization and minimal disruption of the basal plane, exhibited improved performance as both a supercapacitor and a chemical sensor compared to traditional carbon-based materials.

Summary: We synthesized a compound with a phenylthioether moiety at both position 2 and position 8 of the 3-nitroimidazo[1,2-a]pyridine scaffold using a reported synthetic route. The compound showed low solubility in HepG2 culture medium and weak activity against the tested kinetoplastids, including L. donovani, L. infantum, and T. b. brucei.

Summary: A novel three-dimensional hierarchical porous lead-carbon composite (Nano-PbO@3DCSHPAC) derived from corn stover biomass is prepared to address the problems associated with high hydrogen evolution reaction (HER) occurrence and irreversible sulfation of the negative electrode. The addition of PbO in the Nano-PbO@3DCSHPAC composite effectively inhibits HER and acts as a nucleus, refining the sponge Pb grains and maintaining the high electrochemical active area of the electrode. The Nano-PbO@3DCSHPAC composite with high porosity and specific surface area provides good ion channels and inhibits irreversible sulfation, resulting in improved battery discharge capacity and cycling life.

Summary: The facile synthesis of end-functionalized poly(quinolylene-2,3-methylene)s using aryl palladium initiators has been reported. The method allows for the convenient preparation of versatile aryl halides and results in polymers with narrow molecular weight distribution and quantitatively introduced aryl groups at the alpha-chain end. It has also been successfully applied to a one-pot polymerization and can be used with various aryl halides to obtain end-functionalized polymers with different substituents.

Summary: This work presents a practical, portable, and versatile electrochemical cell with three integrated electrodes for microscale electroanalysis. The electrodes were fabricated using 3D printing technology and a commercial carbon black-polylactic acid filament, while the cell was constructed using alternative materials. The cell allows for low sample volumes and can be used with various commercial micropipettes, enabling electroanalysis under both static and flowing conditions. Proof-of-concept experiments demonstrated that the cell exhibited improved sensitivity in the hydrodynamic mode compared to the stationary mode, and its analytical performance for catechol was comparable to a commercial screen-printed electrode. The versatility of the cell was further demonstrated in square wave anodic stripping voltammetry, where it achieved a significantly lower detection limit compared to a conventional system. The cell showed promising analytical feasibility for the determination of catechol and lead in tap and ground water, with recovery rates close to 100%. Moreover, the proposed cell is cost-effective, compact, and more versatile than other tip-based and 3D-printed cells, making it suitable for on-site analysis and educational purposes.
