No full textWe present an x-ray study of freely suspended hexatic films of the liquid crystal 3(10)OBC. Our resultsreveal spatial inhomogeneities of the bond-orientational (BO) order in the vicinity of the hexatic-smectic phasetransition and the formation of large-scale hexatic domains at lower temperatures. Deep in the hexatic phaseup to 25 successive sixfold BO order parameters have been directly determined by means of angular x-raycross-correlation analysis (XCCA). Such strongly developed hexatic order allowed us to determine higher ordercorrection terms in the scaling relation predicted by the multicritical scaling theory over a full temperature rangeof the hexatic phase existence

No full textCrystal chemistry and selected physical properties of inorganic fluorides and oxide-fluorides
No full textimportance in the development of many new technologies, andare impacting various key points of modern life, that is, energyproduction and storage, microelectronics and photonics,catalysis, automotive, building, etc. Many research fields andapplications are indeed concerned by a better knowledge of therelationships occurring between the structure of suchcompounds and some pertinent physical properties. ThisReview deals with the structural chemistry of solid-stateinorganic fluorides and oxide-fluorides, mostly transitionmetal-based, including rare-earth elements. Such a Review hasnot been published for a long time.1 Articles that recentlyappeared on inorganic fluorinated compounds were mostlyfocused on material science characteristics: morphology, surfacefunctionalization, nanostructuration of the materials andapplications, rather than on the description of characteristicstructural features.2â5 Detailed reviews focused on rare earthbasedinorganic fluorides have also appeared some yearsago..
