Summary: Polydopamine (PDA) is a synthetic model for melanin and exhibits photo-responsive free radical properties under visible light. This discovery allows PDA to serve as a photo-redox catalyst and sensitizes exogenous species through photoinduced electron transfer. The utility of PDA nanoparticles as a photosensitizer is demonstrated by initiating free-radical polymerization of vinylic monomers. This study provides crucial insights into the photoactive free radical properties of melanin-like materials and highlights a promising application for PDA as a photosensitizer.

Summary: A flexible CeO2 nanostructured polydopamine-modified carbon cloth (CeO2/PDA/CC) interface was fabricated for ethanol detection. The fabrication method involved electrodeposition of dopamine on carbon fibers followed by electrochemical growth of CeO2 nanoparticles. The CeO2/PDA-based electroactive interface exhibited impressive electrochemical performance due to the synergistic effect of PDA functionalization and active sites. The CeO2 nanostructures anchored on conductive CC contributed to superior electrocatalytic performance. The designed electrochemical sensor showed wide response range, low detection limit, good anti-interference ability, and excellent repeatability and reproducibility, making it suitable for practical implementation in saliva samples.

Summary: Recent studies have shown that bimetallic carbide, due to its abundant active sites, high conductivity, and electrochemical stability, is a promising electrode material for supercapacitors. By combining bimetallic carbides with other advanced materials such as graphene, porous carbon, or carbon nanotubes (CNTs), the electrochemical properties of the electrode can be greatly enhanced. In this study, Fe3Mo3C/Mo2C@CNTs composite material was synthesized for the first time using hydrothermal and high-temperature carbonization methods. The Fe3Mo3C/Mo2C@CNTs nanoparticles carbonized at 800℃ exhibited the best electrochemical performance, with a specific capacitance of 196.3 F g-1 at a scanning rate of 10 mV s-1 (202.3 F g-1 at 1 A g-1). An asymmetric supercapacitor assembled with Fe3Mo3C/Mo2C@CNTs and NiCo2O4 electrode achieved an energy density of 39.9 Wh Kg-1 at a power density of 1800 W Kg-1, with a capacitance retention rate of 73.9% after 4000 cycles. Overall, Fe3Mo3C/Mo2C@CNTs shows significant potential as a negative electrode material for supercapacitors in the field of electrochemical energy storage.

Summary: Perovskite materials SrFexCo1-xO3-delta (SCF-x, x = 0.2, 0.5, 0.8) were synthesized by sol-gel combustion and studied as electrode materials for supercapacitors. The synthesized samples were characterized using X-ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), Raman spectroscopy, Scanning Electron Microscope (SEM), and Energy Dispersive X-ray Spectroscopy (EDS). Substitution in the perovskite structure affected the oxygen vacancy concentration and changed the electrochemical properties. SCF-0.8 exhibited the highest specific capacitance (433 F center dot g(-1)) at 2 A center dot g(-1) current density due to its morphology, crystal structure, and higher oxygen vacancy concentration. The electrochemical stability of SCF-0.8 was tested and it retained around 60% of its initial specific capacitance after 2500 charge-discharge cycles.
