In this experimental work, PbS/ZnS/ZnO nanocomposite was synthesized via a simple co-precipitation method. The effect of Zn2+/Pb2+ mole ratio was investigated on the product size and morphology. The products were characterized via scanning electron microscopy to obtain product size and morphology. The optical properties of the nanocomposites were studied by ultra violet-visible spectroscopy. Ph...

In our report entitled “Treatment of Cooley’s Anemia” (Blood 76:435, 1990), we described a deferoxamine provocation test in which we measure serum iron and iron-binding capacity following an infusion of the chelator. In the report, we failed to state clearly that we do not use standard colorimetric tests to make these measurements. The mild reducing agents used in most colorimetric assays do no...

Total diet sample/Elements/Atomic absorption spectrometry/Element correlation Total diet samples were collected from two urban areas in Japan, Sapporo and Kyoto, during the period from 1967 to 1968. The samples, ashed by dry-ashing and acid-digestion, were analyzed for elements by atomic absorption spectroscopy with the flame and electrothermal atomization. Average daily intake found in the two...
