The Linus program [a] was an experimental fusion power project developed by the United States Naval Research Laboratory (NRL) starting in 1971. [2] The goal of the project was to produce a controlled fusion reaction by compressing plasma inside a metal liner. The basic concept is today known as magnetized target fusion.
When fusion is complete, the sample is tipped into a mold (usually iron) where the slag floats to the top, and the lead, now alloyed with the precious metals, sinks to the bottom, forming a 'button'. After solidification, the samples are knocked out, and the lead bullets recovered for cupellation, or for analysis by other means.
The sodium fusion test, or Lassaigne's test, is used in elemental analysis for the qualitative determination of the presence of foreign elements, namely halogens, nitrogen, and sulfur, in an organic compound. It was developed by J. L. Lassaigne. [1] The test involves heating the sample with sodium metal, "fusing" it with the sample. A variety ...
Sodium peroxide (Na 2 O 2) is used to oxidize the sample that becomes soluble in a diluted acid solution. This method allows complete dissolution of numerous refractory compounds like chromite, magnetite, ilmenite, rutile, and even silicon, carbides, alloys, noble metals and materials with high sulfide contents.
Vacuum fusion is an analytical chemistry technique, used for determining the oxygen, hydrogen, and sometimes nitrogen content of metals. While ineffective when used on alkali or earth metals , vacuum fusion remains a viable means when applied to almost all other metals.

In many laboratories, it is the original place of record of data (no copying is carried out from other notes) as well as any observations or insights. For data recorded by other means (e.g., on a computer), the lab notebook will record that the data was obtained and the identification of the data set will be given in the notebook. [ 4 ]
