Samples of aluminosilicate refractory after operation in the shaft and hearth a coke-gas cupola were investigated; this was used for smelting cast iron with spheroidal graphite using carbon wastes from aluminium electrolysis production as reducing agent. Use only fluorine-containing solid fuel allows to utilize hazardous man-caused wastes, improves economic performance has influence on resistan...

Analysis of fluorine and chlorine in 228 samples of granitoids' from the Basin and Range province of the western United States suggests that at least three types of granitoids can be distinguished: (1) fluorine-poor granitoids of the northwestern Great Basin (mean F = 0.041 wt %, maximum = 0.11 wt %) intrude a variety of allochthonous oceanic or island-arc terranes that were probably accreted t...

Ultracold dysprosium gases, with a magnetic moment 10 times that of alkali atoms and equal only to terbium as the most magnetic atom, are expected to exhibit a multitude of fascinating collisional dynamics and quantum dipolar phases, including quantum liquid crystal physics. We report the first laser cooling and trapping of half a billion Dy atoms using a repumper-free magneto-optical trap (MOT...

A non-layer-shrinkage fluorinated ferroelectric liquid crystal compound, 8422[2F3], has been characterized by means of optical, x-ray, and calorimetric methods. The orientational distribution within macroscopic volumes, determined through wide-angle x-ray scattering and birefringence measurements, was found to be identical in the Sm-A* and helical Sm-C* phases. Together with the absence of laye...

The title compound, (C(10)H(18)N)(2)[GeF(6)], was obtained hydro-thermally from an aqueous solution of GeO(2), H(3)BO(3), NiCl(2), adamantylammonium chloride, butanol and hydro-fluoric acid. The structure consists of discrete bis(1-adamantylammonium) cations lying on crystallographic mirror planes and hexa-fluoridogermanate anions disordered about sites of 2/m point symmetry. In the latter, the...

Surface chemistry is a major factor that determines the wettability of materials, and devising broadly applicable coating strategies afford tunable selective surface properties required for next-generation materials remains challenge. Herein, we report fluorinated metal–organic coatings display water-wetting oil-repelling characteristics, wetting phenomenon different from responsive induced by ...

The viscosities of eight melt compositions in the System albite-H20-F20_1 have been determined at high pressure and temperature. Measurements were performed using the falling sphere method at 1000-1600°C and 2.5 to 22.5 kbar. Fluorine and water strongly decrease the viscosity of albite melt at all pressures and temperatures investigated. The viscosity of a fluorine-bearing albitic melt decrease...

In polar aprotic organic solvents, fluorine might be an element of choice for life that uses selected fluorinated building blocks as monomers of choice for self-assembling of its catalytic polymers. Organofluorine compounds are extremely rare in the chemistry of life as we know it. Biomolecules, when fluorinated such as peptides or proteins, exhibit a "fluorous effect", i.e., they are fluorophi...

1,10-Phenanthroline-2,9-dicarboxamide complexants decorated with alkyl chains and imidazolium cations have been studied for extraction of trivalent f-ions into imidazolium ionic liquids. The dicationic complexants are shown to extract Am over Eu with separation factors >50 and high extraction efficiencies. The different size selectivities for lanthanide ions were observed for these two types of...

In this chapter we describe molecular dynamics simulation methods in which the system being studied is divided into a region where quantum mechanics (QM) is used to determine forces for doing Born-Oppenheimer direct dynamics calculations (i.e., doing electronic structure calculations on the fly to determine energies and forces) and another region where empirical potentials that are commonly use...
