    Innate host selection in Anopheles vestitipennis from southern Mexico. by Ulloa García, Armando, Arredondo Jiménez, Juan Ignacio, Fernández Salas, Ildefonso, Rodríguez, Mario Henry, González Cerón, Lilia

    Published 2004
    “…Host selection experiments in the Lacandón Forest revealed the same trend. These findings suggested that the complex mode of inheritance that resulted in female mosquitoes showing a stronger tendency to return to their preferred host was obscured by the nature of the method of collection, i.e., wild parental females selecting a host either innately or opportunistically, the majority of which were likely innately attracted. …”

    Comparative study of CO2 photoreduction using different conformations of CuO photocatalyst: Powder, coating on mesh and thin film by Avila López, Manuel Alejandro, Gavrielides, Stelios, Luo, XiaoJiao, Ojoajogwu, Abah Ezra, Tan, Jeannie Z.Y., Luévano Hipólito, Edith, Torres Martínez, Leticia Myriam, Maroto Valer, M. Mercedes

    Published 2021
    “…Hence, in this work different conformations of CuO-based photocatalyst, namely powder (i.e., synthesized using precipitation, sonochemical and hydrothermal-microwave treatment), coating on glass fiber mesh, and thin film, were tested using the same photoreactor and experimental conditions. All CuO photocatalysts exhibited 100 % product selectivity towards CH4 over CO and the CuO coating on the glass fiber mesh exhibited the highest production of CH4 (56.3 μmol gcat − 1h− 1). …”

    Open-Circuit Voltage (VOC) Enhancement in TiO2-Based DSSCs: Incorporation of ZnO Nanoflowers and Au Nanoparticles by Borbón Rojas, Susana, Lugo Loredo, Shadai, Pourjafari Nokandeh, Dena, Pineda Aguilar, Nayely, Oskam, Gerko, López, Israel

    Published 2020
    “…Detailed analysis with electrochemical impedance spectroscopy and intensity-modulated photovoltage and photocurrent spectroscopies (IMVS and IMPS) reveal that the main reason for the increase of VOC is related to the shift of the band edges upon coupling TiO2 with ZnO nanoflowers, even though the electron lifetime at the same charge density actually decreases. These results show the intricate interplay between band edge shift, recombination kinetics, and DSSC performance and illustrate that a higher voltage DSSC can be fabricated by modification of the photoanode materials.…”
