[GA16(PtBu2)10]: A gallium phosphide sheathed core of four naked Ga atoms?
Steiner, Jochen,Stoesser, Gregor,Schnoeckel, Hansgeorg
, p. 1971 - 1974 (2003)
Like inverse P4O10, a nearly tetrahedral Ga4P10 shell encloses a gallium-rich core with a distorted tetrahedral Ga4 center in the neutral metalloid cluster compound [Ga16(PtBu2)10].
Competitive interactions and glassy state extension in lithium salt solutions

We report measurements of high- and low-temperature limits of the liquid states of aqueous solutions for two common aqueous salt solutions. The liquid range extends from the glass transition temperature to the boiling point, and is maximized when the anion basicity is minimized. These limits and other characteristic temperatures have been determined by DTA and DSC studies of solution samples which are used to generate the most complete phase diagram yet available for the LiBr + H2O system. The glass-formation region has been extended by developing an emulsification technique suitable for use with concentrated aqueous salt solutions. Comparison of boiling points, liquidus temperatures, and glass transition temperatures shows that the reduction of the water content below 3H2O per Li+ is accompanied by important energetic effects. These are not present in the corresponding lithium acetate solutions, which exhibit relatively much lower boiling points. This is attributed to the stronger water - anion interaction in the lithium acetate system which is proportional to the anion basicity. Water activity increases and boiling points are lowered when the anions are more basic, but total cohesion, manifested by the glass transition temperature, increases. By contrast, addition of anion complexing salts such as ZnBr2 and ZnCl2 to LiBr-H2O solutions to reduce the anion basicity results in increased boiling points to over 200 ?°C as well as decreased crystallization temperatures. ? 1999 American Chemical Society.
In44 mit In4-Tetraeder und In4Se44 mit In4Se4-Heterocubanstruktur

The reaction of InIBr with LiC(SiMe3)3*2THF yields the In(I) alkyl In44 1 in 70percent yield. 1 was characterized by a crystal structure determination showing a nearly undistorted In4 tetrahedron with mean In-In distances of 300.2(1) pm.Reaction of 1 with elemental Se gives In4Se44 2 with a slightly distorted In4Se4 hetero cubane structure.Keywords: Indium; Tetrahedron; X-ray structure; Cluster; Selenium; Heterocubane
Synthesis, characterization, and catalytic behavior of methoxy- and dimethoxy-substituted pyridinium-type ionic liquids

, p. 3362 - 3367 (2014/12/11)
Synthesis of methoxy-substituted pyridinium-type ionic liquids from a nontoxic and easy method is described. Catalytic behaviors of synthesized ionic liquids were investigated with various concentrations for the Mannich reaction. We have observed that methoxy- and dimethoxy-substituted pyridinium bromides showed better catalytic behavior than other ionic liquids.
PROCESS FOR THE RECOVERY OF MATERIALS FROM A DESULFURIZATION REACTION

Page/Page column 3-4, (2010/02/13)
Disclosed herein is an improved method for regenerating materials from a desulfurization/demetallation reaction. The desulfurization/demetallation reaction preferably has products including one or more of an alkali sulfide, polysulfide or hydrosulfide, or alkali earth sulfide, polysulfide, or hydrosulfide. The method includes the steps of reacting the desulfurization/demetallation products with a halogen, liberating and removing sulfur from the product, and then electrolyzing the halogenated products to separate the halogen from the alkali metal or alkali earth metal.
