000889197 520__ $$aPair-distribution function (PDF) analysis of total neutron scattering data has proved tobe an indispensable tool for scientists to determine the local crystal structure ofnanoparticles that often differs in significant ways from their bulk counterparts. The PDFanalysis provides quantitative information about arrangement of atoms on atomic scale,enabling studies of defects, surface relaxations and local disorder in nanoparticles. Inthis talk, I will give an introduction to the method, including practical aspects of datareduction and data corrections. I will briefly present several software solutions for thePDF data analysis. The differences between neutron and x-ray PDF measurements andtheir advantages for studies of nanoparticles will be discussed. The PDFinstrumentation available to users at large-scale neutron and synchrotron facilitiesaround the globe will be reviewed. I will focus on three examples that amplifyimportance of the PDF analysis in nanoparticle research. They include PDF studies ofcoated Co nanoparticles1, exchange biased Au-Fe3O4 dumbbells2 and GaN/ZnOnanoparticles3 used in the visible-light photocatalysis. In the last part of the talk JCNS-2PhD student Nileena Nandakumaran will reflect on her experience on performingsynchrotron x-ray PDF measurements on iron-oxide nanoparticles. As a first time user,she will share her overall experience on challenges of collecting PDF data and onrunning remote PDF experiments, which has been becoming more and more importantduring these days.1 Feygenson, M., Formo, E.
