in this study, a sodalite nanozeolite was synthesized and characterized by x-ray diffraction (xrd) and scanning electronic microscopy (sem). following the morphology evolution of the sodalite nanozeolite in the sem images illustrates the formation of the spherical particle with a size between 60 and 80 nm. then, carbon paste electrode (cpe) was modified by sodalite nanozeolite and ni2+ ions. th...

Palladium nanoparticles supported on carbon black powder (Vulcan XC-72) nanocomposite (Pd/C) are synthesized as the catalyst for the anodic oxidation of glucose for use in a direct glucose alkaline fuel cell (DGAFC). Characterization of the catalyst is carried out using physical and electrochemical methods. It is observed that Palladium nanoparticles are uniformly dispersed onto the carbon blac...

Exploiting electrocatalysts with high activity for glucose oxidation is of central importance for practical applications such as glucose fuel cell. Pt-decorated nanoporous gold (NPG-Pt), created by depositing a thin layer of Pt on NPG surface, was proposed as an active electrode for glucose electrooxidation in neutral and alkaline solutions. The structure and surface properties of NPG-Pt were c...

This article introduces the radical approach of applying alkaline anion-exchange membranes (AAEMs) to meet the current challenges with regards to direct methanol fuel cells (DMFCs). A review of the literature is presented with regards to the testing of fuel cells with alkaline membranes (fuelled with hydrogen or methanol) and also to candidate alkaline anionexchange membranes for such an applic...

background: clinical evidence indicates the diabetes-induced impairment of osteogenesis caused by a decrease in osteoblast activity. flavonoids can increase the differentiation and mineralization of osteoblasts in a high-glucose state. however, some flavonoids such as luteolin may have the potential to induce cytotoxicity in osteoblast-like cells. this study was performed to investigate whether...
