Journal ArticleDOI
Microstructural evolution during the sintering of nanostructured ceramic oxides
Andrew J. Allen,Andrew J. Allen,Susan Krueger,Ganesh Skandan,Gabrielle G. Long,Horst Hahn,Horst Hahn,Helen M. Kerch,Helen M. Kerch,John C. Parker,Mohammad N. All +10 more
TL;DR: Using small-angle scattering, together with density measurements, X-ray diffraction, nitrogen adsorption, and both transmission and scanning electron microscopy, the microstructural evolution during sintering in nanostructured ceramic oxides has been studied.
Journal ArticleDOI
Small-angle neutron scattering studies of ceramic nanophase materials
Andrew J. Allen,Andrew J. Allen,Susan Krueger,Gabrielle G. Long,Helen M. Kerch,Helen M. Kerch,Horst Hahn,Horst Hahn,Ganesh Skandan +8 more
TL;DR: In this paper, the properties of nanophase microstructures in nanostructured zirconia and yttria-stabilized nanostructure were investigated.
Journal ArticleDOI
Application of Neutron Scattering Methods to Cementitious Materials
TL;DR: In this article, quasi-elastic neutron scattering is used to follow non-destructively the progress of the main hydration reaction and to determine the distribution of the water content among the various states: i.e. free, chemically bound, or physically trapped in the gel network.
Comprehensive Microstructural Characterization and Predictive Property Modeling of Plasma-Sprayed Zirconia Coatings | NIST
Anand A. Kulkarni,Z G. Wang,T Nakamura,Sanjay Sampath,Allen Goland,Herbert Herman,Andrew J. Allen,Jan Ilavsky,Gabrielle G. Long,J. Frahm,Rolf W. Steinbrech +10 more
TL;DR: In this paper, microstructure parameters determined by SANS studies are then assembled into a preliminary model to develop a predictive capability for estimating the properties of these coatings, and thermal conductivity and elastic modulus were predicted using finite element analysis and ultimately compared to experimental values.
Proceedings ArticleDOI
Versatile USAXS (Bonse-Hart) facility for advanced materials research
TL;DR: The USAXS facility at UNICAT Sector 33 at the Advanced Photon Source (APS) is a world-class resource for advanced materials research emphasizing full-range characterization of nanometer-scale to micrometer-scale microstructures as mentioned in this paper.
