Summary: Plasmonic nanomaterials of gold and silver have been reported to have antibacterial effect. This study focused on the antibacterial properties of three gold nanomaterials and silver nanoparticles and their response to incandescent light. The results showed that gold nanorods exhibited significant bactericidal effect, while gold nanospheres had no antibacterial activity. The antibacterial effect of gold nanorods was attributed to their higher surface reactivity and the generation of hydroxyl radicals and photothermal effect when exposed to light. The photodynamic and photothermal effects led to bacterial inactivation through cell membrane damage, lowering of cell membrane potential, and DNA degradation. This study suggests the potential of using gold nanorods for photoactivated bacterial inactivation.

Summary: Research has shown that carbon quantum dots (CQDs) exhibit excellent photophysical properties, making them promising as novel carbon nano-materials in photodynamic therapy. However, the high cost of precursors, time-consuming production processes, and complex forms of doping/functionalization have hindered their economic design and use. In this study, ST-JHCQDs were prepared using natural plant turmeric as the carbon source through a simple and environmentally friendly method. The antibacterial effects of ST-JHCQDs on E. coli and S. aureus under blue light irradiation were found to depend on carbonization degrees, concentration, and light duration. ST-JHCQDs were effective in generating reactive oxygen species (ROS) under blue light irradiation, which led to disruption of cell membrane integrity and leakage of intracellular macromolecules in both bacteria, as observed through biomolecule leakage and confocal laser scanning microscope analysis.

Summary: This study presents an innovative approach to improve the photovoltaic conversion characteristics and stability of perovskite solar cells through carbon electrode interface modification. By in-situ polymerization and carbonization on the surface of nano-graphite, a dendritic structure carbon electrode is formed, reducing the work function and aligning the energy levels with perovskite. This leads to improved charge and hole collection efficiency, resulting in increased photovoltaic conversion efficiency. Furthermore, the modified carbon electrode-based perovskite solar cells exhibit exceptional stability, maintaining high efficiency even without encapsulation.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
