Analysis of nanostructure and nanochemistry by ASAXS: Accessing phase composition of oxyfluoride glass ceramics doped with Er 3 + / Yb 3 +
TL;DR: In this article, the analysis of the nanostructure and average chemical compositions of each phase present in an oxyfluoride glass ceramic, which is composed of fluoride nanocrystals and an oxide glass matrix, is described.
ASAXS study on the formation of core-shell Ag/Au nanoparticles in glass.

TL;DR: Measurements at x-ray energies slightly below the Au L(3) edge indicate the formation of bimetallic Ag/Au shells in some of the nanoparticles for high-dose ion implantation, which revealed the considerable influence of the respective particle configuration.
Direct Accessing the Nanostructure of Carbon Supported Ru-Se Based Catalysts by ASAXS
Sylvio Haas,Gerald Zehl,Iris Dorbandt,Ingo Manke,Peter Bogdanoff,Sebastian Fiechter,Armin Hoell +6 more
TL;DR: A structural model of selenium-modified ruthenium nanoparticles was derived from anomalous small-angle X-ray scattering (ASAXS) and smallangle neutron scattering (SANS) experiments as mentioned in this paper.

Yttria-zirconia coatings studied by grazing-incidence small-angle X-ray scattering during in situ heating
TL;DR: The morphology of sol-gel derived dip-coated yttria-doped zirconia films containing variable amounts of yTTria has been studied using in situ grazing-incidence small-angle X-ray scattering (GISAXS) whilst heated incrementally to 1000 °C.
