TLDR
A differential scanning calorimeter with a temperature range of 77 to 873 K was developed for use in combination with either time-resolved X-ray scattering or high-resolution energy-dispersive powder diffraction studies using synchrotron radiation as mentioned in this paper.Abstract:
A differential scanning calorimeter with a temperature range of 77 to 873 K has been developed for use in combination with either time-resolved X-ray scattering or high-resolution energy-dispersive powder diffraction studies using synchrotron radiation. The first results of successful experiments are briefly described.read more

A SAXS/WAXS/GISAXS Beamline with Multilayer Monochromator
Alexander Hexemer,Wim Bras,James Glossinger,Eric Schaible,Eliot Gann,Richard A. Kirian,Alastair A. MacDowell,Matthew Church,Bruce Rude,Howard A. Padmore +9 more
TL;DR: In this article, the authors discuss the construction of a new SAXS/WAXS beamline at the Advanced Light Source at Lawrence Berkeley Laboratory, which is equipped with a multilayer monochromator in order to obtain a high X-ray flux.

Modes of Crystallization in Block Copolymer Microdomains: Breakout, Templated, and Confined
TL;DR: The authors examined the melt and solid-state structures of a series of diblock copolymers containing polyethylene as the minority block, with a rubbery hydrocarbon majority block.

Gelatinisation of starch: a combined SAXS/WAXS/DSC and SANS study
Paul J. Jenkins,Athene M. Donald +1 more
TL;DR: It is found that water enters the amorphous growth rings first, and that this is where all the swelling is concentrated, and the crystallisation index drops to zero, rather beyond the end of the endotherm revealed by DSC.

Polymer crystallization confined in one, two, or three dimensions
TL;DR: In this paper, the authors examined the crystallization behavior of polyethylene-b-poly(vinylcyclohexane) diblock copolymers, E/VCH, using a combination of transmission electron microscopy (TEM), dilatometry, and time-resolved small-angle X-ray scattering (SAXS).

TL;DR: A set-up has recently been developed that combines threeX-ray-based techniques, small- and wide-angle X-ray scattering (SAXS/WAXS) and quick-scanning EXAFS (QEXAFS), for the study of dynamical chemical processes, and revealed important new insights into the interplay of the various stages of ZnAPO-34 formation.
