Temperature and frequency-dependent dielectric properties of 15% monovalent Li doped multiferroic GdMnO3 sample have been studied. A thermally activated relaxation with activation energy ~ 0.17 eV has been determined. An excellent fit of frequency dependent dielectric permittivity data with Curie-Von Schweidler’s function having n

Bracket fungi such as Fomes fomentarius (“tinder fungus”), have strong, light and tough fruit bodies that make them interesting role-models for bio-inspired, biodegradable applications. So far, little is known about the relation between their microstructure and mechanical properties, information needed for designing novel composites. The fruit bodi...

Al3+-doped ZnO micro–nanospheres (AZO MNSs) were obtained in the method of collochemistry at a low cost, and the effects of the concentration of Al3+ on morphology, structural and gas-sensitive properties of the AZO MNSs were investigated. It was found that Al3+ doping reduced the particle size distribution of the MNSs and, in addition, also signif...

AbstractThe influences of electrochemical reduction degrees of reduced graphene oxide (rGO)-based electrode on its electrochemical sensing performance toward heavy metal ions (HMIs) were investigated. Initially, graphene oxide was synthesized by the modified Hummers’ method. Then, rGO films with different degrees of electrochemical reduction were p...

In this work, the open-circuit voltage (Voc) of the dye-sensitized solar cells has been enhanced using a modified ruthenium dye. Two modified ruthenium dyes with formulas: Ru(bpy)2(bqdi) (PF6)2 (Ru-D1) and Ru(bpy)2(dmbqdi) (PF6)2 (Ru-D2) were prepared with chemical route. The FT-IR, structure, thermal and optical properties of the synthesized dye w...
