Journal ArticleDOI
Soft x-ray ptychography studies of nanoscale magnetic and structural correlations in thin SmCo5 films
Xiaowen Shi,Xiaowen Shi,Peter Fischer,Peter Fischer,V. Neu,D. Elefant,James Lee,James Lee,David A. Shapiro,Maryam Farmand,Tolek Tyliszczak,Hung-Wei Shiu,Stefano Marchesini,Sujoy Roy,S. D. Kevan,S. D. Kevan +15 more
TL;DR: In this article, high-resolution magnetic x-ray spectromicroscopy at xray photon energies near the cobalt L3 resonance was applied to probe an amorphous 50 nm thin SmCo5 film prepared by off-axis pulsed laser deposition onto an xray transparent Si3N4 membrane.
Journal ArticleDOI
Holographic Analysis of Diffraction Structure Factors
Stefano Marchesini,Norman Mannella,Charles S. Fadley,Van Hove,Jerome J. Bucher,David K. Shuh,Lorenzo Fabris,M. Press,Mark W. West,W.C. Stolte,Zahid Hussain +10 more
TL;DR: In this article, the authors combine the theory of inside-source/inside-detector x-ray fluorescence holography and Kossel lines/ x ray standing waves in kinematic approximation to directly obtain the phases of the diffraction structure factors.
Journal ArticleDOI
Structure of a single particle from scattering by many particles randomly oriented about an axis: toward structure solution without crystallization?
Dilano K. Saldin,V. L. Shneerson,Malcolm R. Howells,Stefano Marchesini,Henry N. Chapman,Michael J. Bogan,David A. Shapiro,David A. Shapiro,Richard A. Kirian,Uwe Weierstall,Kevin Schmidt,John C. H. Spence +11 more
TL;DR: In this article, a complete algorithm for determining the electron density of an individual particle from diffraction patterns of many particles, randomly oriented about a single axis, is presented. But the algorithm operates on angular correlations among the measured intensity distributions.
Journal ArticleDOI
Augmented projections for ptychographic imaging
TL;DR: In this article, a relaxation of common projection algorithms is introduced to account for instabilities given by intensity and background fluctuations, position errors, or poor calibration using multiplexing illumination.
Journal ArticleDOI
Powder diffraction from a continuous microjet of submicrometer protein crystals.
David A. Shapiro,David A. Shapiro,Henry N. Chapman,Henry N. Chapman,Daniel P. DePonte,R. B. Doak,Petra Fromme,Gary G. Hembree,Mark S. Hunter,Stefano Marchesini,Stefano Marchesini,Kevin Schmidt,John C. H. Spence,D. Starodub,Uwe Weierstall +14 more
TL;DR: The first powder diffraction patterns from a membrane protein, photosystem I, with crystallite sizes of less than 500 nm are presented, and these preliminary patterns show the lowest-order reflections, which agree quantitatively with theoretical calculations of the powder profile.
