Trace element concentrations in human blood serum have been measured by x-ray fluorescence and by x-ray excitation with protons to test the current effectiveness of each technique for routine analysis of biological samples. Results are compared with those obtained from analysis by flame atomic ...

Name an element in the third period (row) of the periodic table with three valence electron. Use the periodic table to give the name and symbol for each of the following elements: (a) the halogen in the same period as the alkali metal with 11 protons (b) the alkal...
Depending on the kind and energy of the projectile particles, a large varietyof different nuclear reactions can be induced in each target nuclide as compa-red with thermal neutrons. For example, with 5 to 15 MeV protons, mainly p,n—reactions occour; with deuterons mainly d, n and d, p ...
83. Li et al.84confirmed the beneficial effects of Mo on the formation of passive films in Ni68Cr22Mo10alloy through a comparison with an Ni78Cr22alloy and pure Ni and Mo. Mo could facilitate the active-to-passive transition in the low potential domain by comparing the potentiodynamic ...
In Table 3, we exemplify some of the results of such computer simulations, normalised to 1013 neutrons produced by the source (23 MeV protons on a thick Beryllium target) and injected in the Activator with the geometry described in Table 6. We have chosen a Molybdenum salt Na2MoO4 (other ...
The yield, the weight average molecular weight, and the results by FT-IR and FT-NMR with respect to each of the resultant polysilane compounds were shown in Table 5. The copolymerized ratio of the silane monomer in each case was obtained by the number of protons in the NMR. In the...
A method of manufacturing a component. In a preferred embodiment, the method includes enriching an element with an isotope and using the enriched element as a material of the component. A property of the first isotope being the same as a property of a se

Contributions to the production of 24Na in Al beam monitors due to secondary particles from the interaction of 28 GeV protons with uranium, thorium, and tantalum targets were measured. Per 100 mg/cm 2 of target thickness they were found to be 13% for U and Th, 7.8% for Ta. The ...
