ZnO and ZrO2 photo catalysts were synthesized by sol-gel auto combustion method. The products were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Structural and morphological properties of nano particles were investigated and the average crystalline size of ZnO and ZrO2 was obtained 44 and 51 nm, respectively. Also, photo catalytic degrada...

Synthesis of BaFe12O19 magnetic nano particles via precipitation in different pH conditions have been reported. The certain molar ratio of Fe/Ba = 12 selected and sodium hydroxide was used as a precipitant agent. X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM) and vibrating sample magnetometer (VSM) were used to consider the structural, morphological and magnetic properties of bariu...

Piezoelectric materials capable of converting between mechanical and electrical energy have a great range of potential applications in micro- and nano-scale smart devices; however, their performance tends to be greatly degraded when reduced to a thin film due to the large clamping force by the substrate and surrounding materials. Herein, we report an effective method for synthesizing isolated p...

Highly nonlinear bistable current-voltage (I-V) characteristics are necessary in order to realize high density resistive random access memory (ReRAM) devices that are compatible with cross-point stack structures. Up to now, such I-V characteristics have been achieved by introducing complex device structures consisting of selection elements (selectors) and memory elements which are connected in ...

The mechanisms underlying the cytotoxic action of pure fullerene suspension (nano-C60) and water-soluble polyhydroxylated fullerene [C60(OH)n] were investigated. Crystal violet assay for cell viability demonstrated that nano-C60 was at least three orders of magnitude more toxic than C60(OH)n to mouse L929 fibrosarcoma, rat C6 glioma, and U251 human glioma cell lines. Flow cytometry analysis of ...

cofe2o4 have been synthesized via a surfactant assisted gel microwave route with a molar ratio of fe/co= 2 and oleic acid (oa) was used as a surfactant. fourier transform infrared spectroscopy (ftir), x-ray diffraction (xrd) and scanning electron microscopy (sem) were used to consider the structural and morphological properties of cofe2o4 nano-particles. results demonstrated that oleic acid is ...
