The acute administration of lithium chloride significantly inhibits both prolactin and growth hormone secretion in the rat. In terms of known neuroendocrine relationships this finding indicates that lithium administration alters both dopamine (DA) and serotonin (5-HT) activity in the hypothalamus. The data suggest that DA activity is increased (inhibiting prolactin release) and 5-HT activity is...

Although it has been known for almost two centuries, lithium is suddenly making the news: it is the primary ingredient of the lithium-ion batteries set to power the next generation of electric vehicles and, as such, could become as precious as gold in this century1. It is also non-uniformly spread within the Earth’s crust, sparking rumours that Andean South American countries could soon be the ...

After an introduction to lithium insertion compounds and the principles of Li-ion cells, we present a comparative study of the physical and electrochemical properties of positive electrodes used in lithium-ion batteries (LIBs). Electrode materials include three different classes of lattices according to the dimensionality of the Li ion motion in them: olivine, layered transition-metal oxides an...

Exchange of intracellular sodium for extracellular lithium readily occurs in vascular smooth muscle, but the mechanism of this exchange is not known. These studies examined whether a sodium-lithium countertransport system was present in the cell membrane of vascular smooth muscle. A sarcolemmal-enriched vesicle preparation was obtained from canine superior mesenteric artery via a magnesium aggr...

This critical review targets as a readership researchers generally oriented toward organic synthesis and in particular those active in heterocyclic chemistry. Diazines and benzo derivatives can undergo deprotonative metalation provided that the base is properly chosen. Metalation reactions of a large range of substrates can be performed using hindered lithium dialkylamides such as lithium 2,2,6...

A remarkable α-effect of silicon has been discovered that results in soft nucleophilicity at the Cγ of 3,3-bis(silyl) allyloxy lithium 1. The addition of 1 to α,β-unsaturated carbonyl compounds, including enals, proceeds in a 1,4- over 1,2-manner with medium to good regioselectivity, whereas the parent allyloxy lithium 4 undergoes complete 1,2-addition. The results from DFT calculations of HMPA...

We found that two lithium niobate-type oxides, CdPbO3 and PbNiO3 were synthesized by high-pressure as metastable low-pressure perovskite-type phases. We then discussed the stability of lithium niobate-type and perovskite-type oxides relative to oxides with other structure for ABO3 compounds. Consequently, the tolerance factor of perovskite is not the only predominant one to determine the stabil...

Palladium-catalyzed direct cross-coupling of aryl chlorides with a wide range of (hetero)aryl lithium compounds is reported. The use of Pd-PEPPSI-IPent or Pd2(dba)3/XPhos as the catalyst allows for the preparation of biaryl and heterobiaryl compounds in high yields under mild conditions (room temperature to 40 °C) with short reaction times.

In the search for fast lithium-ion conducting solids for the development of safe rechargeable all-solid-state batteries with high energy density, thiophosphates and related compounds have been demonstrated to be particularly promising both because of their record ionic conductivities and their typically low charge transfer resistances. In this work we explore a wide range of known and predicted...
