We use the Berry-phase-based theory of macroscopic polarization of dielectric crystals formulated in terms of Wannier functions, and state-of-the-art Gaussian basis functions, to obtain benchmark ab initio Hartree-Fock values of the Born effective charges of ionic compounds LiH, LiF, LiCl, NaF, and NaCl. We find excellent agreement with the experimental values for all the compounds except LiCl ...

An unusual beta-elimination reaction involving zinc(II) and LiCl is reported. LiCl and a coordinatively saturated disilazido zinc compound form an adduct that contains activated SiH moieties. In THF/toluene mixtures, this adduct is transformed into a zinc hydride and 0.5 equiv. cyclodisilazane. The Li(+) and Cl(-) ions apparently affect the reaction pathway of the disilazido zinc in a synergist...

The use of LiCl-treated baits and carcasses has been advocated as a means of controlling coyote predation on sheep through a process known as "aversive conditioning or taste aversion." While some investigators have made well publicized claims of damage reduction through the use of LiCl on sheep ranges, other researchers have experienced difficulty establishing prey aversion in captive coyotes. ...

Two-cell mouse embryos were cultured in vitro for different periods in a medium in which NaCl was partially replaced by LiCl at concentrations ranging from 1 to 30 mM. The relative cell number diminished according to increasing LiCl concentrations but the onset of blastulation was not affected, thus resulting in blastulae with fewer cells than normal and with a reduced or absent inner cell mass...

Ortholithiations of a range of arenes mediated by lithium diisopropylamide (LDA) in THF at -78 degrees C reveal substantial accelerations by as little as 0.5 mol % of LiCl (relative to LDA). Substrate dependencies suggest a specific range of reactivity within which the LiCl catalysis is optimal. Standard protocols with unpurified commercial samples of n-butyllithium to prepare LDA or commercial...

a homogeneous ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate doped with licl ([bmim]bf4-licl) was found as catalyst solvents for the synthesis of dicoumarols by the condensation of 4-hydroxycoumarin and aldehyde at 80 ˚c. in this field, several types of aromatic aldehyde, containing electron-withdrawing groups as well as electron-donating groups, were rapidly changed to the correspo...

Cellulose and its derivatives films are increasingly used in paper, packaging, other fields, but there is limited research on with anti-counterfeiting patterns. Here, we demonstrate an approach to prepare cellulose film a micro-millimeter scale pattern by lithium chloride (LiCl) crystal template, which grows out the in-situ generation formation process. The surface morphologies of as-prepared w...

Continuum photoabsorption of lithium chloride (LiCl) was investigated using a coupled-channel time-dependent wave packet approach. Photodissociation cross sections for the production of ground-state Li and Cl atoms were computed up to temperatures of 1500 K for a thermal distribution of rotational levels. At such temperatures, LiCl is believed to be the primary Li-bearing gas in cool stellar at...

Significant efforts have been dedicated to developing Ti3C2Tz-based MXene aqueous supercapacitors (SCs) with improved energy and power densities. Notably less research has devoted an equally important characteristic of SCs, viz. self-discharge (SD). The SD rates are rarely reported despite their crucial importance from a practical point view. Herein, the in four different electrolytes: H2SO4, K...

Two experiments, using rats as the subjects, and flavour aversion learning with an injection of lithium chloride (LiCl) unconditioned stimulus (US), examined effects a context shift between phases procedure on retardation produced by preexposure to US. Experiment 1 showed that US-preexposure effect (the reduction in size conditioned aversion) was not attenuated when animals were given both US c...
