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 ...
Proton amelioration of Al toxicity is expected to be less relevant for plants grown in acid soils because high concentrations of protons enhance the release of Al3+ from the solid phase and can reduce Ca2+ and Mg2+ uptake. Nitrification contributes to soil acidification (Han et al., 2015; ...
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)...

It was toward the end of the previous century that the commercial production techniques of aluminum were established, owing their success to the electrolytic reduction process. This development made it possible to use aluminum commercially and to exploit
In this arrangement, each of the 12 surface facets provides a polyethylene substrate to convert neutrons to protons, covered by a layer of absorbing material, acting as a proton absorber, with the detector stacked on the absorbing layer to count protons passing through the absorbing layer....

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...
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 ...
