“X-ray Nanovision”

Attempts to produce focusing x-ray optics date back to the days of Roentgen, however, it was not until the past decade that X-ray Microscopy has finally been able to achieve sub-100 nm resolution. In my talk I will introduce a novel x-ray microscopy technique, which relies on coherent properties of x-ray beams, and eliminates the need for focusing optics altogether, replacing it with a computational algorithm. We have applied this technique to image magnetic stripe domains in GdFe multilayer films, as well as to image the distribution of lattice strain in nanostructures. I will also discuss recent results of in-operando imaging of lithium ion diffusion and dislocation dynamics in lithium ion energy storage devices. I will discuss applications of these novel x-ray imaging methods in context of new generation of fully coherent x-ray sources.

BIO:
Oleg Shpyrko received his Ph.D. from Harvard University in 2004. After working as a postdoctoral fellow at Center for Nanoscale Materials at Argonne National Laboratory, in 2007 he moved to University of California, San Diego where he is currently an Associate Professor of Physics. Since joining UCSD, Shpyrko has been a recipient of NSF CAREER award, Hellman Fellowship and Rosalind Franklin Award. His group at UCSD is actively involved in application of synchrotron scattering and imaging techniques to problems ranging from structure and dynamics of polymers, liquid surfaces and nanoparticles and nanowires to studies of magnetic, orbital and charge-ordered materials
