A major limitation of in situ XRD and TEM is a compromise that has to be made between spatial and temporal resolution(1-6). Here, we report the development of in situ X-ray nanodiffraction to measure high-resolution diffraction patterns from single grains with up to 5 ms temporal resolution. We observed, for the first time, grain rotation and lattice deformation in chemical reactions induced by X-ray photons: Br- + hv -> Br + e(-) and e(-) + Ag+ -> Ag-0. The grain rotation and lattice deformation associated with the chemical reactions were quantified to be as fast as 3.25 rad s(-1) and as large as 0.5 angstrom, respectively. The ability to measure high-resolution diffraction patterns from individual grains with a temporal resolution of several milliseconds is expected to find broad applications in materials science, physics, chemistry and nanoscience."],["dc.identifier.doi","10.1038/nmat4311"],["dc.identifier.gro","3141880"],["dc.identifier.isi","000356631200019"],["dc.identifier.pmid","26053760"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/68453"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-352.6"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.eissn","1476-4660"],["dc.relation.issn","1476-1122"],["dc.relation.orgunit","Institut für Röntgenphysik"],["dc.relation.workinggroup","RG Salditt (Structure of Biomolecular Assemblies and X-Ray Physics)"],["dc.subject.gro","x-ray scattering"],["dc.title","Grain rotation and lattice deformation during photoinduced chemical reactions revealed by in situ X-ray nanodiffraction"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original_ja"],["dspace.entity.type","Publication"]]

Characteristic beam configurations with the recently achieved values are also described, meeting the different requirements of the applications, such as spot size, coherence or bandwidth.
