Hard X-Ray Nanoprobe based on Refractive X-Ray Lenses

AIP Conference Proceedings, 2005
Based on nanofocusing refractive x-ray lenses a hard x-ray scanning microscope is currently being developed and is being implemented at beamline ID13 of the European Synchrotron Radiation Facility (Grenoble, France). It can be operated in transmission, fluorescence, and diffraction mode.

Synchrotron‐Based X‐Ray‐Sensitive Nanoprobes for Cellular Imaging

Advanced Materials, 2014
It is one of the ultimate goals in cell biology to understand the complex spatio–temporal interplay of biomolecules in the cellular context. To this end, there have been great efforts on the development of various probes to detect and localize specific biomolecules in cells with a variety of microscopic imaging techniques.

X-ray linear dichroism of defects in GaN:Mg using hard x-ray nanoprobe

Applied Physics Letters, 2009
In this study, we report the application of synchrotron radiation nanoprobe techniques to the structural analysis of pyramidal defects in Mg doped GaN. A combination of fluorescence mapping with spectroscopic techniques enabled us to examine not only the elemental nature but also their crystallographic orientation on the submicron scale.

A hard x-ray nanoprobe for scanning and projection nanotomography

Review of Scientific Instruments, 2009
To fabricate and qualify nanodevices, characterization tools must be developed to provide a large panel of information over spatial scales spanning from the millimeter down to the nanometer. Synchrotron x-ray-based tomography techniques are getting increasing interest since they can provide fully three-dimensional (3D) images of morphology, elemental ...

Studying single nanocrystals under high pressure using an x-ray nanoprobe

Review of Scientific Instruments, 2011
In this report, we demonstrate the feasibility of applying a 250-nm focused x-ray beam to study a single crystalline NbSe3 nanobelt under high-pressure conditions in a diamond anvil cell. With such a small probe, we not only resolved the distribution and morphology of each individual nanobelt in the x-ray fluorescence maps but also obtained the ...

NanoMAX: a hard x-ray nanoprobe beamline at MAX IV

SPIE Proceedings, 2013
We describe the design of the NanoMAX beamline to be built among the first phase beamlines of the MAX IV facility in Lund, Sweden. NanoMAX will be a hard X-ray imaging beamline providing down to 10 nm in direct spatial resolution, enabling investigations of very small heterogeneous samples exploring methods of diffraction, scattering, absorption, phase

Nanoscopium: a Scanning Hard X-ray Nanoprobe Beamline at Synchrotron Soleil

AIP Conference Proceedings, 2010
Nanoscopium is the single scanning hard X‐ray nano‐probe beamline planned at SOLEIL. This ∼155 m long beamline will fully exploit the high brilliance and coherence characteristics of the X‐ray beam both for diffraction limited focusing and for contrast formation.

Hard X-ray nanoprobe investigations of the subtissue metal distributions within Daphnia magna

Analytical and Bioanalytical Chemistry, 2013
The unique potential of nanoscale elemental imaging of major/minor and trace-level elemental distributions within thin biological tissue sections of the ecotoxicological model organism Daphnia magna is demonstrated by synchrotron radiation nano-X-ray fluorescence (nano-XRF).
