Determination of mosaicity in oriented stacks of lipid bilayers

“…Both methods indicate that the mosaic distribution has long tails, more consistent with a Lorentzian than a Gaussian, although the ring method indicates a tail that is somewhat shorter than a Lorentzian for our most extensively analyzed dry sample. As recent papers that determine pole figures emphasize 11–13 , such determinations are greatly facilitated by the use of area detectors. Compared to the traditional rocking scan, an advantage of analyzing a Bragg ring is that fewer exposures are required and the angular range is not limited (due to a non-transparent substrate) to the [0,2θ B ] range of rocking scans.…”

“…As the bilayers in each domain are in-plane powders and there is only one-dimensional stacking order, the only characterizing parameter for the mosaicity is the angle α between the mean normal to the stack and the normal to the substrate; this is simpler than the more complex pole figure characterization of general thin films consisting of crystallites. 11–13 …”

Texture in thin film silicides and germanides: A review

“…measurement from hours to minutes, allowing one to measure a pole figure every few minutes while heating the sample at a steady heating rate. 38 …”

“…31 In the following years, detailed texture studies of different silicide and germanide materials were carried out using this technique, revealing axiotaxy in a considerable number of silicide/germanide materials (see Table I). More recently, the use of a linear or area detector instead of a point detector 37,38 and the introduction of EBSD as a complementary technique 41 have enabled the ability to perform unambiguous phase identification of highly textured transient phases that form during the formation of NiSi 33,35 or NiGe 103 (see Section IV A). In the near future, area detectors will be routinely used to record texture information in situ, enabling the study of texture evolution during silicide/germanide formation.…”

Fast pole figure acquisition using area detectors at the DiffAbs beamline – Synchrotron SOLEIL. Erratum

“…In the article by Mocuta et al (2013Mocuta et al ( , x3, p. 1845, there is an error in the referencing of programs used to deal with the treatment of X-ray data acquired using area detectors. Rather than 'FIT2D (Boesecke, 2007; http://www.esrf.eu/computing/scientific/FIT2D)', the text should read 'SAXS (Boesecke, 2007), FIT2D (Hammersley et al, 1994(Hammersley et al, , 1996; http://www.esrf.eu/computing/scientific/FIT2D)'.…”
