Journal ArticleDOI
Observation of x-ray radiation pressure effects on nanocrystals
Jong Woo Kim,Jong Woo Kim,Andrew Ulvestad,Andrew Ulvestad,Sohini Manna,Ross Harder,Edwin Fohtung,Andrej Singer,Leandra Boucheron,Eric E. Fullerton,Oleg Shpyrko +10 more
TL;DR: In this article, the authors reported abrupt and irreversible Bragg peak movement during the coherent x-ray data collection process for both Pd nanocubes and a Ni nanowire.
Journal ArticleDOI
Synchrotron X-ray studies of rapidly evolving morphology of self-assembled nanoparticle films under lateral compression.
TL;DR: This study reveals the existence of a transient bilayer phase and provides a microscopic picture of the particle-level crinkling phenomena of ultrathin films, which were previously impossible due to the relatively short time scales involved in crinkleling formation of these transient phases.
Journal ArticleDOI
Microscopic and macroscopic signatures of antiferromagnetic domain walls.
Rafael Jaramillo,Thomas Rosenbaum,E. D. Isaacs,Oleg Shpyrko,Paul G. Evans,Gabriel Aeppli,Z. Cai +6 more
TL;DR: Magnetotransport measurements on small single crystals of Cr, the elemental antiferromagnet, reveal the hysteretic thermodynamics of the domain structure.
Journal ArticleDOI
Pairing Interactions and Gibbs Adsorption at the Liquid Bi-In Surface: A Resonant X-Ray Reflectivity Study
Elaine DiMasi,H. Tostmann,Oleg Shpyrko,Patrick Huber,B. M. Ocko,Peter S. Pershan,Moshe Deutsch,Lonny E. Berman +7 more
TL;DR: In this article, resonant x-ray reflectivity measurements from the surface of liquid were used to quantify compositional changes induced at a liquid alloy surface, and it was shown that surface adsorption in Bi-In is dominated by attractive interactions that increase the number of bi-In neighbors at the surface.
Journal ArticleDOI
Surface-induced order in liquid metals and binary alloys
TL;DR: In this article, surface x-ray scattering from pure liquid metals (Hg, Ga, and In) and from three alloys (Bi, In, and K-Na) with different heteroatomic chemical interactions in the bulk phase are reviewed.
