Summary: This study proposes a novel AuNC-based ECL sensing platform and explores the regulation mechanism of electron transfer on ECL. By investigating the ECL quenching effect of OM-AuNCs under the influence of Cu2+, it is found that the ECL intensity of OM-AuNCs is affected by the electron transfer process, enabling sensitive detection of Cu2+ in a low concentration range without the need for amplification techniques. This study enriches the application of ET-mediated ECL and promotes a more rational design of ECL sensors.

Summary: The synthesis of ZnO in an aqueous solvent is best achieved at a reaction and drying temperature of 40 degrees C without the need for additional surfactants or freezing. Lower temperatures result in the formation of Zn(OH)2 or a mixture of Zn(OH)2/ZnO, while higher temperatures lead to larger nanoparticles. The optical properties of the synthesized ZnO show a red shift in the band gap of approximately 0.1 eV.

Summary: Gold nanoparticles (AuNPs) were functionalized by ruthenium porphyrins through a sulfur/gold covalent bond using a three-step reaction. The catalyst was characterized by scanning electron microscopy (SEM) and thermogravimetric analysis (TGA) to control the binding of ruthenium porphyrin on AuNPs' surface. The catalyst was tested and compared with an analog system not bound to AuNPs in the oligomerization reaction using 1-phenylacetylene as the substrate. The results showed that the catalyst exhibited better catalytic activity compared to the analog system without binding to AuNPs.

Summary: Three novel diketopyrrolopyrrole (DPP) based small molecules were synthesized and characterized in terms of their chemical-physical, electrochemical and electrical properties. The molecules have a central DPP electron acceptor core symmetrically functionalized with donor bi-thienyl moieties and flanked by three different auxiliary electron-acceptor groups. The molecular structure allows for significant absorption at longer wavelengths and has a narrow optical bandgap. Organic field-effect transistors (OFETs) were fabricated using the DPP dyes as active layers and showed different charge-transport properties depending on the end-functionalization. Additionally, well-balanced ambipolar transistors were achieved by blending the most performant n-type and p-type dyes.

Summary: The report investigates the relationship between synthesis methods and the size and morphology of copper oxide nanoparticles. It is found that hydrothermal synthesis without surfactants leads to spheroidal dandelion-like aggregates, while the addition of surfactants promotes directional growth of nanostructures. The structure and properties of the nanoparticles are studied using powder X-ray diffraction, scanning electron microscopy, and diffuse reflectance spectroscopy. The effect of morphology on electronic properties is evaluated using DRS, and the results are compared with computational models.
