The number of incident protons was measured with a Faraday Cup. A detailed evaluation of the uncertainties was performed.The cross section for the C-nat(p,x)C-11 reaction at 100 MeV is (70.2 +/- 1.6 (sys.) +/- 0.2 (stat.)) mb. The production cross sections from Al-27 at 100 ...
Aluminum cannot be produced by the electrolysis of an aluminum salt dissolved in water because of the high reactivity of aluminum with the protons of water and the subsequent formation of hydrogen gas. As in aqueous solution, protons (H+) are preferentially reduced before Al3 + ions, leading ...
All elements are arranged in the periodic table by their atomic number -- the number of protons in their nucleus. Aluminum's lucky number is 13, so an aluminum atom has 13 protons. It also has 13 electrons. The elements located above and below aluminum on the periodic table form a ...
Chart: Why recycling aluminum makes sense. The amount of energy it takes to recycle metal for reuse (orange bars) is a fraction of what it takes to produce virgin metal in the first place (blue bars), but the difference is much greater for aluminum (center) than for either steel (left)...
Al-26 is produced from argon in the atmosphere by spallation caused by cosmic-ray protons. Aluminium isotopes have found practical application in dating marine sediments, manganese nodules, glacial ice, quartz in rock exposures, and meteorites. The ratio of Al-26 to beryllium-10 has been used ...

7; b ¼ the 1H13C-HSQC NMR experiment verifies that the two signals of the CH2CH3 protons in the 1H NMR spectrum correlate to one resonance in the 13C{1H} NMR analysis produced by the CH2CH3 carbon atoms; c ¼ the resonance superimposes with the signal produced by the NMR solvent...

Aluminum drastically increased the amount of protons released per unit of root surface area, especially with the NB9040 line. This shift in proton flux density was partly the result of a decrease of the specific root surface area and partly due to enhanced excess of catlonic nutrients taken up...
