fungous infection to saprolegnia is the most important difficulties at the egg of acipenser persicus which is controlled by malachite green as an effective structure . because of the effects and adverse imposition on human and various fish, its use has been avoided in most of the world more than two decades approximately. this study was aimed to compare the antifungal effect of zinc oxid nano p...

INVESTIGATION OF THE INFLUENCE ZINC OXID CONTENT AND SCAFFOLD MORPHOLOGY ON MECHANICAL PROPERTIES POLY(ε-CAPROLACTONE) / OXIDE NANOCAMPOSITE SCAFFOLDS

Evening: Yellow Ointment (Ung. Hydrarg. Oxid. Flav. 2 per cent.) 2nd day, morning: Yellow Ointment. Evening: Yellow ointment. 3rd day, morning: Yellow Ointment. Evening: Zinc Sulph. and Ichthyol Ointment (\ per cent. each). 4th day, Operation. If there is discharge, we continue the yellow ointment until it ceases and the eye is fit for operation. Usually after three or four days, the eye is fre...

zinc oxide nanotubes were prepared by a hydrothermal method using zinc nitrate as a precursor. The synthesized nanotubes were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR) and their optical properties were characterized using UV -visible spectroscopy. The XRD analysis confirme...

We report a comprehensive theoretical study of structural and electronic properties of substitutional oxygen and zinc contaminations in a model of single wall GaN nanotubes by means of ab initio supercell calculations. Our investigation yields many interesting results. The following ones deserve to be developed. Oxygen forms a shallow donor in the single wall GaN nanotubes as in bulk GaN polyty...
