Nanostructured zinc oxide (ZnO) nanorods (NRs) with hexagonal wurtzite structures were synthesized using an easy and low-cost bottom-up hydrothermal growth technique. ZnO thin films were prepared with the use of four different solvents, namely, methanol, ethanol, isopropanol, and 2-methoxyethanol, and then used as seed layer templates for the subsequent growth of the ZnO NRs. The influences of ...

OBJECTIVES To analyse the effect of zinc supplementation in growth and nutritional status of a homogeneous group of newborns with intra uterine growth retardation and asymmetric growth. The effect of changes of zinc status on growth and leptin serum concentrations was also analysed. POPULATION AND METHODS A double blind, randomised clinical trial was designed in order to detect differences in...

Zinc is presently being used as a micronutrient essential for plant growth in agriculture in the form of zinc sulphate in fertilizers. Considering the importance of nitrogen-fixing microorganisms in soil fertility and plant growth, and the toxic effects of zinc, this study aimed at isolating nitrogen-fixing microorganisms from the asparagus rhizosphere arable soil and examining the sensitivity ...

Nanostructured zinc oxide is intensively studied semiconductor showing photocatalytical activity. There are several precursors which can be used for the preparation of nanostructured zinc oxide like zinc acetate, zinc sulphate and many others. Zinc chloride is another compound which can serve as a zinc source for zinc oxide preparation. Nowadays the environmental aspects connected to applicatio...

Somogyi's (6) blood sugar method is one of the most reliable and extensively used method for the estimation of true sugar. Non-sugar reducing substances of blood are located principally in the erythrocytes (3) and are removed from laked blood by adding barium hydroxide and zinc sulphate solution in this method (5). Unfortunately solutions of barium hydroxide are very susceptible to deterioratio...
