Temperature influence on structure

Looking at temperature-induced structure change and phase transitions

What is measured?

The measurement identifies the nanostructure changes with temperature variations.

Temperature range accessible from SAXS Xenocs measurement:

  • -150°C to 1000°C with the Nano-inXider and the Xeuss

Methods & standards

No particular standards & methods are described in the literature. 

XSACT analysis software is used first to display the structure evolution with temperature, and secondly for quantitative study.

Advantages of SAXS

Why use SAXS for dynamic studies ?

  • With SAXS, you can probe the changes in nanostructure as a function of temperature.

  • With simultaneous SAXS and WAXS, you can access atomic and mesoscale information at the same time, with no bias from reproducibility issues.

  • Simultaneous SAXS and WAXS data collection offers access to information over a broad range of length scales.
