Laboratory System for X-ray Nanotomography
Using advanced X-ray technologies and X-ray scattering enhancement in signal detection, a compact laboratory X-ray scanner for 3D non-invasive imaging with 150-200 nanometers 3D detail detectability has been created. This spatial resolution in the volume terms is equal or better than can be achieved in synchrotron tomography, 5 orders better than in existing laboratory instruments and 10-12 ord...
متن کاملA hard x-ray nanoprobe for scanning and projection nanotomography.
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 distribution, and crystallinity of a sample....
متن کاملX-Ray Phase Nanotomography Resolves the 3D Human Bone Ultrastructure
Bone strength and failure are increasingly thought to be due to ultrastructural properties, such as the morphology of the lacuno-canalicular network, the collagen fiber orientation and the mineralization on the nanoscale. However, these properties have not been studied in 3D so far. Here we report the investigation of the human bone ultrastructure with X-ray phase nanotomography, which now prov...
متن کاملIn situ X-ray nanotomography of metal surfaces during electropolishing
A low voltage electropolishing of metal wires is attractive for nanotechnology because it provides centimeter long and micrometer thick probes with the tip radius of tens of nanometers. Using X-ray nanotomography we studied morphological transformations of the surface of tungsten wires in a specially designed electrochemical cell where the wire is vertically submersed into the KOH electrolyte. ...
