bioelectronics has attracted increasing interest in recent years because of their applications in various disciplines, such as biomedical. development of efficient bio-nano hybrid materials is a new move towards revolution of nano-bioelectronics. a novel nano-bio hybrid electrode based on zno–protein for bioelectronics applications was prepared and characterized. the electrode was made by coval...

the pellet-type sno2 sensor was synthesized by the solid state method and the effects of additives such as nano zno (1-12 mol %) and nano in2o3 (1-10 mol %) on the co gas sensitivity of sensor were investigated. the optimum sintering temperature was chosen 800°c because of the porosity content of the samples. the phase analysis and microstructure of the samples were studied by x-ray diffraction...

In this study nano-crystalline ZnO particles were synthesized by microwave-assisted solution combustion method. Zinc nitrate and urea were used as oxidizer and fuel, respectively. The effect of fuel to oxidizer (F/O) ratio on ZnO powder properties was investigated by using different urea/nitrate ratios. X-ray diffractometer, scanning electron microscopy and fourier transform infra-red were used...

ultraviolet waves, because of their short wavelength, have a high energy and considerable damaging effects on surfaces. protection against ultraviolet radiations is one of the finishing treatments done on surfaces exposed to sunlight. the importance of this issue in relation to human health, due to complications such as skin burns and cancer, is doubled. up to now, different materials such as z...

The present study was designed to highlight the impact of seed priming with polyethylene glycol on physiological and molecular mechanism of two cultivars of Oryza sativa L. under different levels of zinc oxide nanorods (0, 250, 500 and 750 mg L(-1)). Plant growth parameters were significantly increased in seed priming with 30% PEG under nano-ZnO stress in both cultivars. Whereas, this increase ...

Al-doped ZnO (AZO) thin films with various Al concentrations were synthesized on Si(001) substrates with native oxide layers by atomic layer deposition process. The effects of the Al concentration on the microstructural characteristics of the AZO thin films grown at 250 degrees C and the correlation between their microstructural characteristics and electrical properties of the AZO thin films we...

ZnO nanoparticles were prepared by hydrothermal method. The modified Hummer process was then used to prepare go. ZnO-GO com posites mixed produce different ratios of ZnO-GO, characteris ed and their photocatalytic properties investigated using rhodamine B as the target degradation species. results showed that r ates 41.96% 84.42% for nano-ZnO 7% composites, respectively, when illuminated with x...

this research evaluates the efficiency of nanosized zno in the catalytic ozonation of 4-chloro-2-nitrophenol and determines the effect of ph on heterogeneous catalytic ozonation. the combined use of ozone and zno catalyst leads to conversion of 98% 4-chloro-2-nitrophenol during 5 min. in addition, it was found that in zno catalytic ozonation, the degradation efficiency of 4-chloro-2-nitrophenol...
