Examining nanoparticle assemblies using high spatial resolution x-ray microtomography
An experimental system has been designed to examine the assembly of nanoparticles in a variety of process engineering applications. These applications include the harvesting from solutions of nanoparticles into green parts, and the subsequent sintering into finished components. The system is based on an x-ray microtomography with a spatial resolution down to 5 mm. The theoretical limitations in...

متن کاملMonitoring sintering of nanoparticle clusters by X-ray microtomography
There has been much effort in recent years to develop methods for producing materials with nanometer scale substructure. The desire is to control the macroscopic material properties such as toughness, elasticity and porosity by tailoring the microstructure. For ceramic materials, one approach is to synthesize nano-scale particles and develop methods for compressing and sintering these powders. ...
متن کاملMetallic foams characterization using X-ray microtomography
Abstact Due to their multi properties, metallic foams have become of major interest for both, basic research as well as industrial applications. In order to implement a thin modelling approach of fluid flows in such porous media, a three dimensional investigation of their internal structure is fundamental. An open-cell nickel foam is imaged using X-ray microtomography. The morphology of the foa...
متن کاملQuantifying Mesoscale Neuroanatomy Using X-Ray Microtomography
Methods for resolving the three-dimensional (3D) microstructure of the brain typically start by thinly slicing and staining the brain, followed by imaging numerous individual sections with visible light photons or electrons. In contrast, X-rays can be used to image thick samples, providing a rapid approach for producing large 3D brain maps without sectioning. Here we demonstrate the use of sync...
