    Nanodimensional sodium silicate glasses of composition 30Na2O.70SiO2 has been prepared within the pores of 5.5 nm of mesoporous silica as a template using the surfactant P123. The nanocomposite was characterized by X-ray diffraction, transmission electron microscope, and X-ray photoelectron spectroscopy. Electrical conductivity of the sample was studied by ac impedance spectroscopy. The activation energy for ionic conduction was found to be 0.13 eV with dc conductivity at room temperature of 10-6 S-cm-1. This is attributed to the creation of oxygen ion vacancies at the interface of mesoporous silica and nanoglass arising out of the presence of Si2+ species in the system. These nanocomposites are expected to be useful for applications in sodiumion battery for storage of renewable energy

    We Editors Are Authors, Too

    “Oh No, Reviewer 3 got our paper rejected again!”, remains a popular phrase that is often used to vent frustration with negative editorial decisions. As practicing scientists, we work on our manuscripts like other authors and submit our papers to see them published quickly. Like every author, we also live with anxiety during the review process. We experience the joy of acceptance and the pain of rejection of our papers. Furthermore, we devote time to review papers for various other journals and upload our comments in a timely fashion. Being editors of ACS Energy Letters is just an additional task in which we are engaged but one we take as much pride in as publishing our own work
