The effect of high pressure on the quadrupole interaction in iron-fluorine compounds
… been observed for the three isomorphic ferric compounds K3FeF6, Na3 FeF6 and (NH4)3FeF6' In addition, the compressibility and the pressure dependence of cia were determined by X-ray diffraction for the ferrous compound FeF2 , In all of these compounds, the local environment of the iron ion is a …

FRUSTRATED LEWIS PAIR-MEDIATED SELECTIVE C–F BOND ACTIVATION AND SUBSEQUENT POST-FUNCTIONALIZATION OF POLYFLUOROALKANES
… materials, and pharmaceuticals. The inclusion of fluorine in such molecules is attractive to enhance solubility, biological activity, chemical resistivity, thermal stability and to act as a spectroscopic probe. Thus, direct access of these fluorine compounds is highly desirable from commercially …

The Biomedical Applications of Protein Microspheres
… MRI agents (T 1 and T2 agents for proton MRI and fluorine compounds for 19F MRI) have applications in imaging tissues with abnormal distributions of phagocytes. Pharmacologically, the unmodified microspheres were rapidly cleared from the blood stream while surface modification did increase the …

Xenon difluoride etching and molecular oxygen oxidation of silicon by reactive scattering
While both molecular fluorine (F₂) and xenon difluoride (XeF₂) fluorinate Si(l00)2xI surfaces at coverages up to one monolayer, fluorine is unable to cleave Si-Si bonds that ultimately leads to etching silicon at coverages above one monolayer (reaction probability 9x 10-⁴) while XeF₂ does so …

Fundamental investigations on the barrier effect of polyester micro fiber fabrics towards particle-loaded liquids induced by surface hydrophobization
… of the material: - Wetting agent - Amount of fluorine content in the chemical - Subsequent heat treatment of the finished material after washing - Ironing of the fabric For the plasma enhanced surface fluorination the following plasma gases were used: - Saturated fluorine compounds: CF4 and …

Chelated fluoroboron cations : synthesis and multinuclear nmr studies
The preparation of chelated difluoroboron cations (DD)BF2+, where DD is a saturated polydentate tertiary-amine or polydentate aromatic ligand, has been systematically studied by using multinuclear solution and solid state nuclear magnetic resonance spectroscopy and fast atom bombardment mass …

Fluorine-containing fullerenes and endometallofullerenes: synthesis, structure, and spectroscopic characterization
… class of exohedral fullerene derivatives with fluorine-containing electron-withdrawing groups have been prepared and studied by spectroscopic methods and X-ray crystallography. The fluorination and/or perfluoroalkylation reactions were performed with C60, C70, the higher hollow fullerenes C60+m …
