IN order to check the constitution of preparations of the three different tritium toluenes carrying radiochemical amounts of tritium in the aromatic nucleus, samples were transformed into ...

Air, pressure, heat, corrosive agents, and other factors encountered by a lubricant during use can cause chemical changes in the oil. Changes in the oil chemistry can have a negative impact on the ...

Chemists have yet another use for fluorine, as a through-space activator for electrophilic aromatic substitutions. Thomas Lectka and coworkers at Johns Hopkins University used a Diels-Alder reaction ...

An in-service lubricant encounters heat, air, corrosive agents, pressure, and other factors that cause chemical changes in the oil. Changes in oil chemistry can also impact the lubricant’s ability to ...
