In this work, we investigated the thermoelectric, electrochemical, and dielectric properties of four different ZnO morphologies, namely nanoribbons, nanorods, nanoparticles, and nanoshuttles. 400), and a network depth equal to 2. Graphene nanosheets were prepared by ultrasonication-based liquid phase exfoliation of graphite powder in a low boiling point organic solvent, 1,2-Dichloroethane, for the preparation of ZnO/graphene nanocomposites. Although ZnO nanomaterials are very attractive for immobilization of low isoelectric enzymes during enzymatic based biosensor fabrications [26,27,28,29,30,31,32,33], ZnO nanomaterials are not considered to be a good candidate for non-enzymatic based biosensor fabrication. The spread of bacterial, fungal, and viral diseases by airborne aerosol flows poses a serious threat to human health, so the development of highly effective antibacterial, antifungal and antiviral filters to protect the respiratory system is in great demand. Increasing demand of high-performance nanomaterials is mostly related to electronic. UA? Зареєструватись. All reagents were purchased from Sigma-Aldrich (Taufkirchen, Germany). , Cu–ZnO–Al 2 O 3 and Cu–ZnO–ZrO 2) are the most widely studied for this process due to the high activity, high product selectivity, and low cost 2,3,6,7.
