Static SIMS is the process involved in surface atomic monolayer analysis, or surface molecular analysis, usually with a pulsed ion beam and a time of flight mass spectrometer, while dynamic SIMS is the process involved in bulk analysis, closely related to the sputtering process, using a DC primary ion beam and a magnetic sector or quadrupole ...
In organometallic chemistry, organolithium reagents are chemical compounds that contain carbon–lithium (C–Li) bonds.These reagents are important in organic synthesis, and are frequently used to transfer the organic group or the lithium atom to the substrates in synthetic steps, through nucleophilic addition or simple deprotonation.

Li 2 C 2 can also be prepared by reacting CO 2 with molten lithium. [citation needed] 10 Li + 2 CO 2 → Li 2 C 2 + 4 Li 2 O. Other method for production of Li 2 C 2 is heating of metallic lithium in atmosphere of ethylene. Lithium hydride is a coproduction: 6 Li + C 2 H 4 → Li 2 C 2 + 4 LiH. Lithium carbide hydrolyzes readily to form ...
Lithium nitride is prepared by direct reaction of elemental lithium with nitrogen gas: [2] 6 Li + N 2 → 2 Li 3 N. Instead of burning lithium metal in an atmosphere of nitrogen, a solution of lithium in liquid sodium metal can be treated with N 2. Lithium nitride must be protected from moisture as it reacts violently with water to produce ammonia:
Lithium sulfate is used to treat bipolar disorder (see lithium pharmacology).. Lithium sulfate is researched as a potential component of ion conducting glasses. Transparent conducting film is a highly investigated topic as they are used in applications such as solar panels and the potential for a new class of battery.
Lithium deuteride, in the form of lithium-7 deuteride (7 Li 2 H or 7 LiD), is a good moderator for nuclear reactors, because deuterium (2 H or D) has a lower neutron absorption cross-section than ordinary hydrogen or protium (1 H) does, and the cross-section for 7 Li is also low, decreasing the absorption of neutrons in a reactor.
Naturally occurring lithium (3 Li) is composed of two stable isotopes, lithium-6 (6 Li) and lithium-7 (7 Li), with the latter being far more abundant on Earth. Both of the natural isotopes have an unexpectedly low nuclear binding energy per nucleon (5 332.3312(3) keV for 6 Li and 5 606.4401(6) keV for 7 Li) when compared with the adjacent lighter and heavier elements, helium (7 073.9156(4) keV ...
Lithium borohydride (LiBH 4) is a borohydride and known in organic synthesis as a reducing agent for esters. Although less common than the related sodium borohydride , the lithium salt offers some advantages, being a stronger reducing agent and highly soluble in ethers, whilst remaining safer to handle than lithium aluminium hydride .
