The Microstructure Of Aging Zno, Azo, And Gzo Films
RF magnetron sputtering is used on the ceramic targets, each of which contains zinc oxide (ZnO), zinc oxide doped with aluminum (AZO) and zinc oxide doped with gallium (GZO). The electric conduction mechanism of the AZO and GZO films came mainly from the Al and Ga, the oxygen vacancies, Zn interstitial atoms, and Al a…

New Issues on Application of Metal-Organic Frameworks (MOFs) on Textiles
Recently the application of nanostructured materials has garnered attention, due to their interesting chemical and physical properties. Application of nanostructured materials on the solid substrate such as fibers brings new properties to the final textile product [1]. Metal-organic frameworks (MOFs) are one of the mo…
High dielectric performance of polymer composites based on BaTiO3-supporting Ag hybrid fillers
The dielectric properties of the polyvinylidene fluoride (PVDF) composites filled with BaTiO3-supporting Ag (BT-Ag) hybrid particles were investigated. The BT-Ag/PVDF composites exhibited a high dielectric permittivity of 160 and relatively low dielectric loss of 0.146 at 100 Hz when the concentration of BT-Ag hybrid…
