Summary: Gold polypyrrole (AuPPy) and copper polypyrrole (CuPPy) nanocomposites were synthesized and evaluated as electrocatalysts for borohydride oxidation reaction. The apparent activation energies for BOR of AuPPy and CuPPy electrocatalysts were 16 and 22 kJ mol-1, respectively. Moreover, when applied in a direct borohydride-peroxide fuel cell, both AuPPy and CuPPy exhibited high open circuit voltage and peak power density.

Summary: This study presents a biosensor based on a core-shell nanostructure consisting of zinc oxide (ZnO) nanoparticles coated with gold (Au). The core-shell nanostructure serves as a support for the immobilization of tyrosinase on screen-printed carbon electrodes to measure dopamine. The results indicate that the biosensor has remarkable selectivity and accuracy for the detection of dopamine in real samples, with a relative error of 3.8%. Additionally, the biosensor has a limit of detection of 86 nmol L-1 and a dynamic range of 0.1 to 500 μmol L-1 for dopamine in real samples. Thus, the proposed miniaturized biosensor device shows promise for the monitoring of dopamine in real samples and could be used for disease diagnosis and prognosis.

Summary: The superhydrophobic/superoleophilic properties of polyurethane foams (PUF) were enhanced through layering with three different polymers and modification with iron/magnetic nanocomposites. The polymer layer and nanocomposites successfully covered the PUF surface, resulting in improved water contact angle and powerful superhydrophobic properties of the materials. The modified PUFs exhibited enhanced oil absorption capacity, high separation efficiency, and rapid oil permeate flux, making them highly useful for oil-water separation applications. Among the modified materials, PDA-coated PUF nanocomposites achieved the most outstanding results due to their remarkable interfacial adhesion properties and increased active functional groups for hydrogen bonding interaction.

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.
