Synchrotron X-ray Microbeam Characterization of Smectic a Liquid Crystals under Electric Field

When an electric field is applied to chiral smectic A (SmA) liquid crystals, a tilt is induced in the director of orthogonal SmA liquid crystals (electroclinic effect). The layer shrinkage due to the tilted smectic arrangement is mitigated by local layer deformation. This paper presents detailed measurements of the local layer spacing under the electroclinic effect of the chiral SmA phase in a ...

Characterization of X-ray area detectors for synchrotron beamlines.

In order to deal with the problem of quantitative and consistent evaluation of two-dimensional X-ray detectors at synchrotron beamlines, the methodology for X-ray area detector characterization is reviewed. It is based on the definition of a minimum yet complete set of imaging parameters able to describe any kind of two-dimensional detector regardless of its operating range, field of applicatio...

Micro X-ray fluorescence in materials characterization

Micro X-ray fluorescence ~MXRF! offers the analyst a new approach to materials characterization. The range of applications is expanding rapidly. Single point analysis has been demonstrated for nanoliter volumes with detection limits at the 0.5 ng level. MXRF can be used as an element specific detector for capillary electrophoresis. Elemental imaging applications include analysis of sample corro...

Synthesis and Characterization of Cr2O3 Nanoparticles with Triethanolamine in Water under Microwave Irradiation

Cr2O3 nanoparticles were prepared using Cr(NO3)3.9H2O as starting material, triethanolamine (TEA) as template and water as green solvent under microwave irradiation. The products were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), Fourier transform infrared (FT-IR), photoluminescence (PL) and Raman spectroscopy. The size distribution of individual particles we...
