Summary: This study reports the synthesis of hybrid nanocomposites with catalytic activity by combining polymer nanofibers and gold nanoparticles. The nanofibers were obtained through electrospinning blends of a poly (ionic liquid) and its precursor polymer. The results showed that the nanofiber characteristics depended on the proportion of polymer in the blends. The obtained nanofibers were used to synthesize gold nanoparticles on their surface, which significantly improved the performance of the nanofibers in ion adsorption and catalytic reactions.

Summary: A screen-printed electrode modified with gold-nanoparticle-decorated reduced graphene oxide-carbon nanotubes (rGO-AuNPs/CNT/SPE) was used for the determination of estradiol (E2) in this study. The eco-friendly production of AuNPs using plant extract eliminated the need for severe chemicals and sophisticated fabrication methods. The rGO-AuNPs/CNT/SPE exhibited improved electrochemical performance compared to bare SPE and GO-CNT/SPE, as shown by the relative peak currents. The optimized estradiol sensor showed linear sensitivity from 0.05-1.00 μM with a detection limit of 3 nM and yielded stable and reproducible outcomes.

Summary: PANI/NC nanocomposites were synthesized by in situ polymerization of aniline monomer in the presence of a stable colloidal solution of nanocarbon NC using ammonium persulfate and Ag+ ions. The morphological studies of the nanocomposites were conducted using TEM and SEM. Characterization of the prepared nanocomposites was further performed using various techniques including IR, XRD, XPS, PSD, FM, UV-VIS spectroscopy, and surface analysis. The nanocomposites showed superior optical and electrical properties, with AC conductivity reaching 1.06 x 10(-2) S.Cm-1 for PANI/NC and 2.5 x 10(-2) S.Cm-1 for PANI/NC/Ag2O. These new nanocomposites have not been reported in the literature before.

Summary: Surface/interfacial engineering plays a critical role in optimizing the electrochemical performance of Li-rich layered oxides (LLOs). This study investigates the surface structure of LLOs and performs surface engineering to enhance their stability and prevent voltage decay. The results show that an integrated spinel/rock salt surface structure forms on the LLO surface, leading to improved cycle stability and low voltage decay. The modified LLO cathode retains a high capacity after 2000 cycles, indicating the stability of the surface layer. The findings suggest that the ISR surface concept and the surface modification method have great potential for the commercialization of LLOs in battery applications.

Summary: Garnet-type solid-state electrolytes are considered as promising fast lithium-ion conductors due to their high room temperature ion conductivity and stability against lithium metal. However, the presence of lithiophobic Li2CO3 at the garnet/Li interface poses challenges for ionic contact. In this study, researchers chemically upcycled the Li2CO3 on the garnet surface through a double replacement reaction with SiO2, forming a stable and lithiophilic LixSiOy (LSO) layer that improved interfacial ion transport efficiency.

Summary: Employing lithium-rich layered oxide (LLO) as the cathode in all-solid-state batteries (ASSBs) is desired for high energy density, but its poor kinetics due to low electronic conductivity and oxygen-redox-induced structural degradation hinders its application. This study enhances the charge transfer kinetics of LLO by constructing efficient electron transport networks within solid-state electrodes, reducing electron transfer resistance, and stabilizes the lattice oxygen of LLO through an infusion-plus-coating strategy, suppressing interfacial oxidation and structural degradation. The LLO-based ASSBs exhibit high discharge capacity and long cycle stability, providing important insights for the development of high-energy-density ASSBs.
