Journal ArticleDOI
Three-Dimensional Coherent X-Ray Diffraction Imaging of a Ceramic Nanofoam: Determination of Structural Deformation Mechanisms
Anton Barty,Stefano Marchesini,Stefano Marchesini,Stefano Marchesini,Henry N. Chapman,Henry N. Chapman,C. Cui,Malcolm R. Howells,David A. Shapiro,Andrew M. Minor,John C. H. Spence,Uwe Weierstall,Jan Ilavsky,Aleksandr Noy,Stefan P. Hau-Riege,Alexander B. Artyukhin,Theodore F. Baumann,Trevor M. Willey,James S. Stolken,T. van Buuren,John H. Kinney +20 more
TL;DR: Finite-element analysis from the structure of the labrynthine internal structure of a tantalum oxide nanofoam reveals mechanical properties consistent with bulk samples and with a diffusion-limited cluster aggregation model, while excess mass on the nodes discounts the dangling fragments hypothesis of percolation theory.
Journal ArticleDOI
Dependence on Crystal Size of the Nanoscale Chemical Phase Distribution and Fracture in Li x FePO 4
Young-Sang Yu,Chunjoong Kim,David A. Shapiro,Maryam Farmand,Danna Qian,Tolek Tyliszczak,A. L. David Kilcoyne,R. S. Celestre,Stefano Marchesini,John Joseph,Peter Denes,Tony Warwick,Fiona C. Strobridge,Clare P. Grey,Clare P. Grey,Howard A. Padmore,Ying Shirley Meng,Robert Kostecki,Jordi Cabana +18 more
TL;DR: Soft X-ray ptychographic chemical imaging is established as an essential tool to build comprehensive relationships between mechanics and chemistry that guide this engineering design of next generation electrical energy storage systems.
Journal ArticleDOI
Alternating projection, ptychographic imaging and phase synchronization
TL;DR: In this paper, necessary and sufficient conditions of the local convergence of the alternating projection algorithm to a unique solution up to a global phase factor were demonstrated, and an accurate initial guess was constructed to accelerate convergence speed to handle the big imaging data in the coming new light source era.
Journal ArticleDOI
Three Dimensional Imaging of Atoms with Isotropic 0.5 Å Resolution
TL;DR: In this article, the first two cobalt neighbor shells with nearly isotropic resolution were obtained, using a combination of normal and inverse, synchrotron and laboratory experiments, and no a priori knowledge of the structure was used.
Journal ArticleDOI
Phasing of coherent femtosecond X-ray diffraction from size-varying nanocrystals.
John C. H. Spence,Richard A. Kirian,Xiaoyu Wang,Uwe Weierstall,Kevin Schmidt,Thomas A. White,Anton Barty,Henry N. Chapman,Stefano Marchesini,James M. Holton +9 more
TL;DR: A method for reconstructing the charge density of a typical molecule within a single unit cell, if sufficiently finely-sampled "snap-shot" diffraction data are available from many nanocrystals of different sizes lying in random orientations is described.
