Fluorinated phases

GPa. The results of DSC analyses (apparent absence of a mobile fluorinated phase) are consistent with the small elongation-at-break reported (5-6%). 

Both tire excellent formability and abrasion resistance should be correlated with the particular biphasic morphology of PFPE-containing coatings owing to the high flexibility of die segregated fluorinated phase. 

Other silica-based phases that are available include phenyl and fluorinated alkyl and phenyl-bonded phases. The phenyl and fluorinated phases offer the potential for n-n interactions and show different selectivity in comparison to...

An original study was done with a perfluoiinated stationary phase whose properties were compared to a classical CIS bonded phase [27, 28]. An important decrease of the methylene selectivity for a homologue series of alkylphenones was obtained with the fluorinated phase with both an SDS... 

Finally, other highly polar phases can be thought of such as various fluorinated phases, Zorbax Bonus RP, or Synergi POLAR RP. 

Reconstructable polymer surfaces form a toolbox for the rapidly developing field of smart coatings and the structure of the coatings can be programmed in the formation. For instance, the colloidal particles formulated by the emulsion copolymerization of acrylate and fluorinated acrylate monomers can form stratified film morphologies, where the fluorinated phase can be driven to the film/ air or film/substrate interfaces. As a result, static and kinetic coefficients of friction can be controlled at the film/air interface, resulting... 

These tables indicate that in the presence of Pluronic surfactant the strength of the adsorption layer at the interface between fluorinated phases and water was two orders of magnitude higher than the strength of the layer formed by the same surfactant at the water-heptane interface. In the case of an adsorption layer formed with the fluorinated surfactant, the opposite effect was observed the strength of this adsorption layer at the water/heptane interface was an order of magnitude higher than that of an adsorption layer formed at the fluorinated hydrocarbon/water interface. 

Purospher RPjg that is endcapped with an aminosilane. In the left upper part of the chart, one finds Fluofix 120N, 5, and at the lower fringe of the chart there is Fluophase RP, 11. Both are fluorinated phases, but other details of the structures of these stationary phases are not known to us. Another phase found in the upper left-hand comer is Discovery HS PEG, 121, which is formed using polyethylene glycol. Packing 122 is the Discovery Cyano packing. 

Treatment of LaACuGaOs (A = Ca, Sr) with Xep2 decreases orthorhombic distortion up to a transformation to a fluorinated phase with a tetragonal symmetry (for A = Sr) with c 2ap [158]. The copper oxidation state in the fluorinated samples depends strongly on the conditions of the fluorination reaction. Fluorination with a large excess...
