Summary: Experimental results show that there are two chemical states for silver on the surface of gold nanorods, and the binding energy of silver atoms depends on their configuration within the nanorods. Theoretical studies suggest that silver atoms located at interstitial sites could distort the crystalline structure, indicating the absence of interstitial silver in gold nanorods.

Summary: A direct low-cost chemical reduction method is presented for the synthesis of the ternary Cu-Cu2O-CuO system, where the presence of graphene oxide helps limit the conversion of copper to copper oxide. The composition of the ternary system can be altered by adjusting the amount of copper precursor used, as confirmed by X-ray diffraction studies and XPS analysis of the synthesized nanocomposites. The enhanced catalytic efficiency of the composite nanostructures towards visible light photodegradation and hydride reduction reactions is attributed to the interaction between graphene sheets and copper, as well as the unique ternary composition of Cu2O-Cu-CuO.

Summary: This study presents the preparation of cationic thiazole phthalocyanines (Pcs) conjugates with nitrogen doped (NGQDs) and nitrogen/sulfur co-doped (NSGQDs) graphene quantum dots (GQDs). The photo-sonodynamic combinatorial therapy (PSDT) activities of the conjugates were tested in vitro with cancer cell lines. The conjugates exhibited the production of reactive oxygen species (ROS) through the treatment technique. The Pc-GQDs generated singlet oxygen and hydroxyl radicals when exposed to light and low frequency ultrasound in PSDT. Cancer eradication was observed in vitro for the PSDT treatment using the Pc-GQDs conjugates. The NGQDs conjugates performed better in terms of ROS generation and cell eradication compared to the NSGQDs conjugates. The PSDT treatments showed increased ROS generation and cancer eradication efficiencies compared to PDT and SDT monotreatments.
