Summary: This study characterizes and compares the parameters of quality reproduction of fine elements in flexography on different substrates, finding that coated paper has higher quality reproduction than OPP film, with uncoated paper showing more irregular ink penetration and loss of original shape. The biggest changes in fine element size are noticeable in OPP film due to ink surface spread. Overall, the study contributes to optimizing the production process and quality of the final graphical product.

Summary: This study demonstrates a powerful direct ink writing (DIW) strategy using thin silver nanowires (AgNWs) as a representative example. Aqueous inks with sodium alginate as the thickening agent can be easily patterned with desired geometries and controllable features on various planar substrates. A postprinting treatment at room temperature further enhances the electrical conductivity and substrate adhesion of the written AgNWs-patterns. This environmentally friendly and low-temperature DIW strategy allows for high-resolution, highly conductive, mechanically robust, and well-aligned AgNWs patterns regardless of the substrate's properties.

Summary: In this study, macroporous melamine/formaldehyde sponge was coated in situ during the oxidation of pyrrole with iron(III) chloride hexahydrate. It was found that the addition of silicotungstic acid resulted in the formation of polypyrrole/silicotungstate deposits in either globular or nanotube form. These hybrid composites combined an organic conducting polymer with an inorganic component and had a large specific surface area. Furthermore, carbonization of the sponges resulted in the formation of macroporous carbon electrodes.

Summary: The study investigates the conductivity of chromium-tanned pigskin leather waste carbonized using various methods to produce nitrogen-containing carbons. Four protocols were tested, and the most effective method involved pre-carbonization followed by activation. It was found that the carbonized material maintained its fibrous collagen morphology, with a slight reduction in yield. The activated products showed improved specific surface area, pore volume, and conductivity. The resistivity of the carbonized leather was determined, and the sample conductivity was relatively unaffected by the carbonization method.

Summary: Polypyrrole-gelatin aerogels containing magnetic barium ferrite particles were synthesized and used for the removal of Cr(VI) from aqueous media. The optimal pH for adsorption was found to be 4, due to the dominance of HCrO4- species and its better adsorption and reduction compared to CrO42-. The presence of magnetic particles did not affect the adsorption performance of the aerogels. The adsorption mechanism involved electrostatic interaction between chromium and the adsorbent.

Summary: Magnetic polypyrrole-gelatin-barium ferrite (PPy-G-BaFe) cryogels/aerogels were successfully synthesized by incorporating barium ferrite nanoparticles into a gelatin solution and conducting one-step oxidative cryopolymerization of pyrrole. The resulting aerogels exhibited higher specific surface area and conductivity compared to PPy-G aerogel prepared without barium ferrite. The magnetic PPy-G-BaFe aerogel with 10 wt% BaFe content showed significantly improved adsorption capacity and rate for anionic dye removal, making it an attractive adsorbent for water purification.

Summary: In this study, a novel type of D-A non-fused-ring copolymers was designed and synthesized to overcome the trade-off relationship between electrical conductivity and Seebeck coefficient in organic semiconductors. The incorporation of fluorine atoms into the polymer backbone effectively increased the ordered degree of molecular stacking and improved both the electrical conductivity and Seebeck coefficient. The bimodal orientation of polymers played a crucial role in decoupling the correlation between electrical conductivity and Seebeck coefficient.

Summary: This research focuses on the versatile substance, polyaniline/layered double hydroxide (PANI@Nd-Co/LDH), under solvothermal conditions. A thorough analysis of its structure and morphology was conducted using various analytical methods. The findings showed that PANI@Nd-Co/LDH exhibited highly sensitive and specific fluorescence detection of Pb(II) and Al(III), outperforming other heavy metal ions. The sensor demonstrated a turn-off fluorescence response for Pb(II) ions and a turn-on fluorescence response for Al(III) ions. The minimum detectable limits (MDL) were determined to be 9.6 nM for Pb(II) and 220 nM for Al(III). PANI@Nd-Co/LDH could be easily regenerated and reused for multiple cycles. The detection mechanisms involved the inner filter effect (IFE) for Pb(II) and the chelation-enhanced fluorescence (CHEF) effect for Al(III). These results highlight the excellent potential of PANI@Nd-Co/LDH in the detection and recognition of Pb(II) and Al(III) ions.
