Summary: In this study, an ECL imaging technique for single cell membrane protein based on Co3O4 nanozyme catalytic enhancement strategy was developed. The highly efficient catalytic performance of Co3O4 nanozymes allows efficient decomposition of H2O2 into reactive oxygen radicals, leading to enhanced reaction with the luminescence reagent L012 and stronger ECL emission. The optimized design of Co3O4 nanozymes coupled with anti-CEA enables specific recognition of overexpressed CEA on the MCF-7 cell membrane, enabling rapid ECL imaging of single cell membrane protein.

Summary: This study develops a strategy for specific chemiluminescence (CL) imaging and enhanced photodynamic therapy (PDT) of bacterial infections using hemin-modified carbon dots (H-CDs). The H-CDs exhibit favorable water solubility, augmented photodynamic activity, and unique peroxidase-mimicking capacity. The H-CDs not only enable infection identification via CL imaging but also enhance bactericidal effects through oxygen self-supply and relief of hypoxia. This work provides an effective antibacterial platform for selective imaging-guided treatment of bacterial infections.

Summary: This study developed three samples of carbon quantum dots (CQDs) with different fluorescence properties as fluorescent probes for the critical micelle concentration (CMC) determination of surfactants. The CMC values were deduced from the fluorescence intensity change and the Stokes shift variation. The study also found that the interaction between CQDs and surfactant molecules is complicated and the CQDs are located at the palisade layer in the surfactant micelles.

Summary: Chiral carbon dots (CDs) were obtained by thermal polymerization of chiral amino acids and citric acid, with the handedness of chirality controlled by adjusting the reaction temperature, leading to different kinds of surface modifications. Aliphatic amino acids resulted in CDs with the same handedness at different temperatures, while aromatic amino acids produced CDs with maintained or inversed handedness based on the temperature adjustment.

Summary: Passive daytime radiative cooling (PDRC) technology, while promising for global spacing cooling, faces limitations in practical application due to reduced cooling effectiveness caused by wear and dirt contamination. Researchers have developed a renewable armor structure using fluorinated hollow glass microspheres to enhance the anti-fouling and cooling properties of PDRC coatings. The coatings exhibit high solar reflectance and thermal emittance, leading to significant temperature reduction below ambient temperature.

Summary: Methane chemistry is a significant area of research in catalysis. Converting methane into value-added chemicals is desirable but challenging due to its high C-H bonding energy and lack of pi bonding or unpaired electrons. Photocatalytic partial oxidation of methane to liquid oxygenates is a promising technology for achieving high efficiency and selectivity under mild conditions. The choice and activation of oxidants are crucial for its performance.
