January 2016 – Chapter from X-ray and Neutron Techniques for Nanomaterials Characterization, pp 507-544 - Peter Siffalovic, Karol Vegso, Martin Hodas, Matej Jergel, Yuriy Halahovets, Marco Pelletta, Dusan Korytar, Zdeno Zaprazny, Eva Majkova

 

thumb x ray and neutron techniques for nanomaterials characterization  

This book chapter presents a thorough introduction to SAXS and GISAXS starting with the mathematical foundation. It gives a review of state-of-the-art instrumentation describing x-ray sources, optics, and detectors, explaining how the metal-jet technology has opened up the possibility to perform time-resolved in-situ studies of weakly scattering materials. Two time-resolved applications are described in more detail to show the current research front.

thumb Laboratory and synchrotron tests of two dimensional parabolic x ray compound refractive lens made of single crystal diamond  

A team from Immanuel Kant Baltic Federal University, FSBI TISNCM and the ESRF joined together to design, manufacture and evaluate two-dimensional parabolic compound refractive lenses made of single-crystal diamond. The evaluation was performed with the MetalJet D2 x-ray source from Excillum as well as at ID06 at ESRF. The combination of unique optical and thermal properties makes them well suited as optical elements at x-ray sources with high-heat flux.

Krenkel APL 2016 2  

A team from University of Göttingen shows high-resolution phase-contrast tomography experiments done on whole mice, with a MetalJet-based laboratory setup. The high brilliance of the MetalJet enables propagation-based phase contrast in local tomography, even though there is highly absorbing tissue surrounding the mouse lung.

thumb-Real-time-SAXS-study-of-a-strain-gauge-based-on-a-self-assembled-goldnanoparticle-monolayer-1  

A group from Slovak Academy of Science in co-operation with people from STU Centre for Nanodiagnostics performed in-situ tests on a strain gauge, based on a monolayer of colloidal gold nanoparticles deposited on a flexible Mylar foil, by small-angle X-ray scattering using a MetalJet X-ray source from Excillum. The high brightness of the MetalJet allowed a very fast data collection, with 10 s temporal resolution. The results of the study indicate that the colloidal gold-nanoparticles on a flexible is a potential future strain gauges with a fast linear response within a wide strain range.

X-ray-grating-interferometry-for-9  

A team from Julius-Maximilians-Universität Würzburg presents a grating interferometer based on a MetalJet X-ray tube, as well as a self-built high resolution detector. They show that the small spot-size of the MetalJet makes the use of a source grating unnecessary. This work was presented at the XRM 2014 in Melbourne, and published in AIP Conference Proceedings 1696 in January 2016.

thumb-x-ray-phase-contrast-tomography-for-high-spatial-resolution-zebrafish  

A KTH/KI group demonstrates that the three-dimensional muscular structure of unstained whole zebrafish can be imaged with sub-5 μm detail with propagation based X-ray phase-contrast tomography. By comparing the X-ray imaging results with histology, it can be confirmed that individual myofibrils can be resolved in the whole-body imaging.

thumb-PNAS-2015-Zanette-12569-73-1  

A TUM/Diamond/KTH/UCL team demonstrates speckle based x-ray phase contrast, applied to material characterization, using a MetalJet x-ray source from Excillum. The method is based on correlation of near-field speckles and yields quantitative measurements of the full X-ray refractive index of the object with high sensitivity. X-ray speckle tracking tomography broadens the capabilities of X-ray imaging at laboratory sources with strong potential in materials and life sciences.

A team from TU Dortmund, Bruker, Cordouan Technologies and KU Leuven demonstrates an innovative way to charactherize nano-particles by combining SAXS, DLS and a microflow reactor. To ensure high enough flux to do time-resolved SAXS, a MetalJet x-ray source from Excillum was used.

thumb-Zanette-Phys  

A TUM/KTH/UCL team demonstrates speckle based x-ray phase contrast using a MetalJet x-ray source from Excillum. In this technique, the x-rays from the MetalJet are scrambled by a random object with small structures (e.g. sandpaper), before reaching the sample. After having acquired the detector image, the signal is decoded and absorption-, phase contrast-, and dark-field contrast can be extracted.
