In situ studies of ultrasound-stimulated fat crystallization using synchrotron radiation

Article Abstract:

Investigations were made which aimed at the effects and mechanism of ultrasound-induced crystallization in tripalmitin (PPP) and trilaurin (LLL) suppercooled melts using situ synchrotron radiation time-resolved small-angle X-ray scattering (SAXS) and wide-angle X-ray scattering (WAXS) techniques. It was possible to describe the behavior of the most important parameters and the events that characterize the crystallization of these systems.

High-resolution analysis of ([Sc.sub.3][C.sub.2])@[C.sub.80] metallofullerene by third generation synchrotron radiation X-ray powder diffraction

Article Abstract:

The structure of [Sc.sub.3][C.sub.82] metallofullerene was redetermined by employing the third generation synchrotron radiation powder data collected at SPring-8, where the [C.sub.2] encapsulated structure available to discuss the Sc-Sc interatomic distances were determined. The obtained structure shows the [C.sub.2] encapsulation in the [C.sub.80] cage together with the Sc-Sc interatomic distances.

Evidence of strong hydration and significant tilt of Amphiphilic [2]Roxane molecules in Langmuir films studied by synchrotron X-ray reflectivity

Article Abstract:

Surface sensitive X-ray techniques are used to elucidate the structures of amphiphilic [2]rotaxane and dumbbell monolayers at the air/water interface. Largely due to the hydrophilic nature of their tetracationic ring component, the [2]rotaxanes are found to adopt highly highdrated tilted and/or folded conformations on the water surface.
