Summary: The MnO2 nanowires/polyaniline composite (MnO2NW/PANI) was prepared by synthesizing MnO2NW via hydrothermal method and then polymerizing aniline monomer on its surface. The composite showed a specific capacitance of 306.7 F/g, 28.4% higher than that of pristine MnO2. The enhanced capacitance was attributed to the reduced electric resistance within the composite and the synergistic effect between MnO2NW and PANI for fast ion/charge transfer. Moreover, the MnO2NW/PANI electrode exhibited stable cycle performance with 88.7% capacity retention after 5000 repeated cycles at a high current density of 5 A/g.

Summary: Introducing carbon-based electrode materials into the value chain of biorefinery can potentially increase profits. In this study, carbon-based supercapacitor electrode materials were synthesized by chemically activating bio-oil and bio-char precursors, resulting in hierarchical porous structures with high surface areas. These materials exhibited nearly double the specific capacitance compared to commercially available activated carbon. Using bio-oil as the precursor offered the advantage of lower metal impurities and slightly better energy storage performance than bio-char. Additionally, a normalized energy storage value was presented for each material to aid in selecting the best economic route for the concept.

Summary: Functionalized gold nanoparticles (GNPs) have been widely used in sensing applications, especially for detecting metal ions. This article describes the use of 13 nm GNPs functionalized by glutathione (GSH) and conjugated with a rhodamine 6G derivative (Rh6G2) to detect Hg(II) in cells. The detection strategy is based on the ion-catalyzed hydrolysis of Rh6G2, resulting in a significant change in the fluorescence of GNPs-GSH-Rh6G2 from an OFF to an ON state.
