We measured the second-harmonic signal generated by high-quality zinc oxide single crystals. Comparing this signal with that generated by single-crystal quartz, used as a standard, we found that the components of the second-order susceptibility tensor differ somewhat from the values reported earlier. Measurements of two zinc oxide single crystals with different orientations yield similar results.

Zinc oxide nanoparticles are highly sensitive towards phosphate ions even at pH 7. Buffer solutions and cell culture media containing phosphate ions are able to destroy ZnO nanoparticles within a time span from less than one hour to one day. The driving force of the reaction is the formation of zinc phosphate of very low solubility. The morphology of the zinc oxide particles has only a minor in...

The study of zinc bioavailability in foods is important because this mineral intake does not meet the recommended doses for some population groups. Also, the presence of dietary factors that reduce zinc absorption contributes to its deficiency. Rice fortified with micronutrients (Ultra Rice®) is a viable alternative for fortification since this cereal is already inserted into the population hab...

A feasibility study on the possible growth of rod-shaped nano size zinc oxide particles on the surface of polyester fabric was investigated. The nanoparticles were produced using a hydrolysis method, with a zinc compound being utilized as the starter material. Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy/energy dispersive X-ray spectrometry (SEM/EDS) and X-ray d...

In this work, the fabrication and characterization of fully solution-processed zinc oxide metal–insulator–semiconductor (MIS) capacitors by ultrasonic spray pyrolysis (USP) are presented. Fluorine tin oxide by USP was used as transparent electrode, while spin-on glass by spin-coating was used as dielectric and zinc oxide by USP was used as active layer. Also, the zinc oxide film was characteriz...

                                                                                  The synthesis of metal nanoparticles has attracted the attention of scientists in various fields, particularly in the chemical, physical, biological and medical sciences. Using extract of plant for nanoparticle synthesis can be advantageous over other biological processes because it eliminates the elaborate proc...

Supplementation with zinc improves overall health, productivity and performance of production animals such as poultry, swine and dairy animals as measured by body weight increase, final body weight or feed/gain ratios. Reports on beneficial effects of zinc supplementation are fewer for companion animals. Lowe et al. (1994 a) reported more hair growth with higher zinc content in dogs upon supple...

Background and Objective: Diabetic mellitus nephropathy is one of the most important implication factors in kidney´s physiological function in diabetes mellitus. Having major role in filtration, in hyperglycemic condition kidney has shown more damages in comparison with other tissues. This study was done to determine the effect of combined Atorvastatin and Zinc oxide on the biochemical and hist...
