The relationship between serum levels of zinc and copper and sexual maturation were analyzed in 2291 9-18-yr-old Finnish girls and boys. Development of pubic hair, breasts, and genitalia were used to grade maturation according to Tanner's classification. Serum zinc and sexual maturation were not...
Molecular modeling of zinc and copper binding with Alzheimer's amyloid ?-peptide Aggregation of the amyloid β-peptide (Aβ) into insoluble fibrils is a key pathological event in Alzheimer's disease. Cu(II) and Zn(II) ions were reported... Han,D.,Wang,... - 《Biometals》 被引量: 24...

Zinc, iron, copper, calcium, and magnesium in pus were measured using an atomic absorption spectrophotometer; selenium was measured fluorometrically. Ferritin was measured with a fluorometric enzyme immunoassay, and lactoferrin was measured with a radial diffusion assay. The growth ofEscherichia coliat ...
The stable isotope geochemistry of Cu and Zn is poorly known because of the lack of a suitable analytical technique. We present a procedure for the analysis of Cu and Zn isotope compositions by plasma-source mass spectrometry (Plasma 54) together with a method to purify Cu and Zn from natura...
To solve the question, we need to identify the alloy that is formed by melting zinc and copper. Here’s a step-by-step solution: Step 1: Understand the Components- The question mentions two metals: zinc and copper. Step 2: Identify the Alloy- When zinc and copper are melted together,...
of formate species or13C-exchange proceed rapidly (Fig.2b, c), while the switch from CO2/H2mixture to hydrogen results in a much slower decomposition of formate together with the formation of copper–zinc alloy. Equally, we should keep in mind, that by switching from CO2/H2to H2and vice...
The sludge product increased barley shoot uptake of Cu hy 112% and of Zn by 67% on average. However, sludge application decreased the shoot Zn concentration by 39% in the clay loam. This may be due to a decrease in EXCH-Zn in the soil together with a dilution effect in the shoots ...
aBrass is an alloy of copper and zinc. It has much better abrasion resistance, better corrosion resistance and lower electrical conductivity as compared with copper. Phosphor bronze is an alloy of tin, phosphorus and copper; it is corrosion, wear and tear resistant, but it is not suitable for...
