Beryllium analysis
… as was shown by the absence of characteristic beryllium lines in the ultraviolet spectrum of these minerals, The sample of Beryl probably containers 10% or less BeO, instead of the 14% as indicated by the Parsons and Barnes method of analysis. Al(OH)₃ is appreciably soluble in the boiling …

A study of beryllium and beryllium-lithium complexes in single-crystal silicon
When beryllium is thermally diffused into silicon, it gives rise to acceptor levels 191 meV and 145 meV above the valence band. Quenching and annealing studies indicate that the 145 meV level is due to a more complex beryllium configuration than the 191 meV level. When lithium is thermally diffused …

Development of a MeVVA based beryllium-7 plasma source
… this MeVVA-type source is to create a confinable beryllium-7 (7-Be) plasma. 7-Be is a peculiar isotope due to its varying radioactive decay half-life in different electro-chemical configurations. It is also found in an unexpected abundance at high altitudes of the Earth's atmosphere. It is …
