We have performed resonant X-ray scattering on two bent-core liquid crystal compounds exhibiting the B2 phase using three sample geometries: free-standing film and two others with free surface arrangements. The results conclusively demonstrate the tw

A method is disclosed for determining the three-dimensional atomic structure of systems that are periodic in two dimensions, a-periodic in the third dimension, and are commensurate with an underlying three-dimensional crystal. The system is considere

We report the first X-ray scattering investigation of spatial variations of the q-fold quasicrystalline symmetry (so-called commensurability) of well-aligned TGBC samples. A spatial resolution of 20 × 40 μm2 was achieved using the ESRF microfocus b

The lyotropic phase behavior of freely suspended multilayers of the phospholipid dimyristoylphosphatidylcholine (DMPC) and water, ranging in thickness from a single bilayer (∼ 50 A) to 12 bilayers, has been investigated via optical reflectivity and

We report structural results that evidence the polarization distribution of the blocks in the columnar phase of an achiral bent-core liquid crystal. The study was performed using resonant x-ray diffraction at the sulfur K edge on oriented samples ali

The compound 10OHF has a partially inverted phase sequence, unique among the series of nOHF homologous compounds and all other known liquid crystals, with the smectic-C*FI2 (SmC*FI2) phase occurring at higher temperature than the smectic-C* (SmC*) ph

A binary mixture of an antiferroelectric liquid-crystal material containing a selenium atom and a highly chiral dopant is investigated using resonant X-ray scattering. This mixture exhibits a remarkably wide four-layer intermediate smectic phase, the

Previous results from Kundu using dielectric relaxation have suggested a reentrant antiferroelectric-ferroelectric-antiferroelectric transition in the compound LN36. Our comprehensive studies of this compound using differential optical reflectivity,
