With the purpose of assessing the reactivity of chloride ions dissolved in ionic liquids (ILs), a relative scale for the solvation of chloride is given for a series of ILs based on the bis(trifluoromethane)sulfonimide ([Tf2N]) anion and differen ...
Self-assembled monolayer (SAM) films have attracted immense attention for both fundamental and applied research. A SAM is composed of a large number of molecules with a head group that chemisorbs onto a substrate, a tail group that interacts with the outer ...
Ruthenium(II)-arene diphosphine complexes are shown to be effective precursors for the catalytic hydrogenation of the C=C bond in an aqueous biphase using molecular hydrogen as the hydrogen source. A mechanistic study performed in water, utilizing high gas ...
Isothermal NaCl sintering experiments are conducted between 500 and 790 degrees C on powders 75, 100, 150 and 400 mu m in average diameter. Along with literature data, the results are compared with theoretical predictions for the initial stage of sintering ...
The practical quantitation limit (PCIL) for arsenic (As) is currently orders of magnitude higher than its nonenforceable, health-based standard in California. Analytical limitations caused by chloride (CO interference can be overcome using high-resolution, ...
The coupling of the flow field flow fractionation to differential refractive index (DRI) and multi-angle laser light scattering detectors is a powerful tool for characterizing charged polysaccharides such as alginate. However, the correct interpretation of ...
Raman scattering and optical birefringence were used in to investigate a low-temp. phase transition in a single crystal of the 2D Na5RbCu4(AsO4)4Cl2. Phonon anomalies point to a 1st-order nature of the transition. The obsd. transition is most probably rela ...
Clusters containing nine lanthanide and six sodium ions are crystallized with the help of a tridentate ligand bearing a phosphonic acid group; the structure of the EuIII compound reveals a host-guest assembly Eu⊂Na6Eu8L16 with a substantial quantum yield ( ...
The oxidation of dimethyl sulfide (DMS, CH3SCH3) in the atmosphere could influence climate by affecting cloud condensation nuclei concentrations and cloud properties. This work focuses on elucidating the importance of DMS-cloud intera ...
In ionic liqs. (ILs), the activation of a ruthenium(II) catalyst precursor occurs via an unexpected mechanism, which is different from the activation mechanism that takes place in water. The effectiveness of a biphasic catalytic hydrogenation reaction usin ...
