Summary: In this work, one-dimensional P-doped carbon nitride nanotubes have been successfully synthesized using supramolecular self-assembly. These nanotubes exhibit great potential as an eco-friendly, visible-light-active photocatalyst for hydrogen evolution reaction. The addition of an ionic liquid improves the uniformity of the nanotubes. Thorough structural and photophysical characterizations reveal that the nanotubes possess larger surface areas, more amine bridges, better crystallinity, and higher visible-light-absorption ability, which contribute to their enhanced photocatalytic performance.

Summary: Multi-wall carbon nanotube (MWCNT) coatings are gaining increasing interest due to their special properties. In this study, a bi-layer coating of MWCNT and titania (anatase structure) was synthesized using the electrophoretic deposition method. The MWCNT/TiO2 coating showed higher roughness, adhesion strength, and corrosion resistance compared to the MWCNT basic coating. Biological tests revealed that the physicochemical properties of the MWCNT/TiO2-coated surface supported cell adhesion but could result in decreased proliferation due to the release of toxic species.

Summary: Highly concentrated aqueous binary solutions of acetate salts show potential for electrochemical applications, including energy storage. These solutions have high solubility and can reduce ion activity, leading to better stability of the electrolyte. The addition of Li+ or Na+ allows compatibility with intercalation materials, making them suitable for rechargeable alkaline-ion batteries. However, a deeper understanding of their physicochemical properties is still needed. In this study, we investigated the properties of solutions with different concentrations of CH3COONa and found that the solution with 20 mol kg(-1) CH3COOK + 7 mol kg(-1) CH3COONa achieved the best balance between transport properties and electrochemical stability.

Summary: We report a facile, metal-free convergent synthesis method and characterization of novel quinacridone dyes with two triptycene units that function as end-caps and steric confinements for the quinacridone chromophore. A precise comparison between the confined dyes and known homologues reveals that the reduction of p-p interactions in triptycene-fused quinacridone dyes, compared to classical quinacridone, leads to increased solubility, processability, fluorescence quantum yield, and photostability in the solid state.
