Real-time X-ray diffraction study at different scan rates of phase transitions for dipalmitoylphosphatidylcholine in KSCN

Determination of Montmorillonite Nanocomposite Aggregation Rates Using Real Time X-Ray Diffraction Techniques at High Temperatures

Phase Transitions in Dipalmitoylphosphatidylcholine Monolayers.

A self-assembled phospholipid monolayer at an air-water interface is a well-defined model system for studying surface thermodynamics, membrane biophysics, thin-film materials, and colloidal soft matter. Here we report a study of two-dimensional phase transitions in the dipalmitoylphosphatidylcholine (DPPC) monolayer at the air-water interface using a newly developed methodology called constrain...

Strength and structural phase transitions of gadolinium at high pressure from radial X- ray diffraction

Phase-targeted X-ray diffraction

A powder X-ray diffraction (XRD) method to enhance the signal of a specific crystalline phase within a mixture is presented for the first time. Specificity to the targeted phase relies on finding coincidences in the ratios of crystal d spacings and the ratios of elemental characteristic X-ray energies. Such coincidences can be exploited so that the two crystal planes diffract through the same s...

An in situ powder diffraction study of the structural mixed-phase of YBa2Cu3O6+x at 200 and 300C

In this study, the YBa2Cu3O6+x samples at temperatures 200 and 300°C, as the value of x ( the oxygen content in 0the basal plane)  increased under nearly thermodynamical equilibrium condition, the structure changed from the well- known tetragonal (T) to a mixed-phase (T+OII) region (orthorhombicII phase is a superstructure). This mixed-phase region suggests a first order T/OII phase transition ...
