Nanoscale X-ray imaging

NATURE PHOTONICS | VOL 4 | DECEMBER 2010 | www.nature.com/naturephotonics X-ray imaging at the nanoand microscale is of great interest for applications in the physical and life sciences. !e associated wavelength range1 extends from a few nanometres to a small fraction of a nanometre, o"ering the potential to image objects at this spatial resolution. !e concomitant photon energies of such wavele...

X-ray peak broadening analysis in LaMnO3+δ nano-particles with rhombohedral crystal structure

In this work, structural and magnetic properties of LaMnO3+δ compound prepared by citrate precursor method and annealed in presence of oxygen are investigated. The structural characterization of LaMnO3+δ by X-ray powder diffraction and using X’pert package and Fullprof program is evidence for a rhombohedral structure (R-3c space group) confirmed by FTIR measurement. The magnetic measurements sh...

Empirical correlation for porosity deduction from X-ray computed tomography (CT)

For obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as X-ray computed tomography, CT, seems to be precise and accurate. Porosity is deducted from the CT image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. More than one hundred samples with carbonate li...

X-ray imaging at the nanoscale

X-ray imaging at the nanoscale Tim Salditt Institut für Röntgenphysik, Universität Göttingen X-rays deeply penetrate matter and thus provide information about the functional (interior) architecture of complex samples, from biological tissues and cells to novel composite materials. However, this potential of hard -rays in view of penetration power, high spatial resolution, quantitative contrast,...
