Ternary transition metals sulfides in hydrotreating catalysis.

2007

International audience; Pure microcrystalline barium molybdate BaMoO4 and barium tungstate BaWO4 materials were prepared by molten flux reaction using alkali metal nitrates as reaction media. The obtained crystals have rhombic shape and expose mostly (111) crystallographic planes. Their mean size depends on the flux temperature and the nature of the alkali metal cation. Monomeric molybdate and tungstate used as precursors yield target products already at 673 K whereas if polymerized ammonium oxosalts were used, then higher temperatures were necessary to obtain barium salts. The optimal temperature for the preparation of pure crystals with well defined shape was found to be near 773 K. UV–vi…

"Table 5" of "The ALICE Transition Radiation Detector: construction, operation, and performance"

2017

Most probable charge deposit signal normalised to that of minimum ionising particles as a function of $\beta\gamma$ for cosmic-ray muons (dE/dx + TR). Statistical uncertainties as vertical error bars. Uncertainties in momentum and thus $\beta \gamma$ determination are drawn as horizontal error bars.

"Table 4" of "Multiplicities of charged pions and unidentified charged hadrons from deep-inelastic scattering of muons off an isoscalar target"

2017

Multiplicities of unidentified negatively charged hadrons from semi-inclusive deep-inelastic scattering of muons off an isoscalar target, $M^{h^{-}}$, in bins of $x$, $y$, and $z$. Also given are the diffractive vector meson correction to the hadron count, $DVM^{h^{-}}$, and DIS count, $DVM^{DIS}$, as well as the radiative correction factors to the hadron count, $\eta^{h^{-}}$, and DIS count, $\eta^{DIS}$. The correction factors were applied to the raw multiplicity to arrive at the final multiplicity given in the table, $M^{h^{-}}$, as follows: $M^{h^{-}}$ = $M_{raw}^{h^{-}}$ * $\frac{\eta^{h^{-}}} {\eta^{DIS}}$ * $\frac{ DVM^{h^{-}} } {DVM^{DIS} }$.
