We demonstrate that phase retrieval and tomographic imaging at the organ level of small animals can be advantageously carried out using the monochromatic radiation emitted by a compact x-ray light source, without further optical elements apart from source and detector. This approach allows to carry out microtomography experiments which – due to the large performance gap with respect to conventional laboratory instruments – so far were usually limited to synchrotron sources. We dem... Read more

The use of novel multi-scale correlative methods, which involve the coordinated characterization of matter across a range of length scales, are becoming of increasing value to materials scientists. Here, we describe for the first time how a multi-scale correlative approach can be used to investigate the nature of ductile fracture in metals. Specimens of a nuclear pressure vessel steel, SA508 Grade 3, are examined following ductile fracture using medium and high-resolution 3D X-ray computed to... Read more

In this paper, porous sintered glass bead packings are studied, using X-ray Computed Tomography (XRCT) images at 16μm16μm voxel resolution, to obtain not only the porosity field, but also other properties like particle sizes, pore throats and the permeability. The influence of the sintering procedure and the original particle size distributions on the microstructure, and thus on the hydraulic properties, is analyzed in detail. The XRCT data are visualized and studied by advanced image fil... Read more

Physical characteristics critical to chromatography including geometric porosity and tortuosity within the packed column were analysed based upon three dimensional reconstructions of bed structure in-situ. Image acquisition was performed using two X-ray computed tomography systems, with optimisation of column imaging performed for each sample in order to produce three dimensional representations of packed beds at 3 μm resolution.

The loss of hearing structures and loss of advertisement calls in many terrestrial breeding frogs (Strabomantidae) living at high elevations in South America are common and intriguing phenomena. The Andean frog genus Phrynopus Peters, 1873 has undergone an evolutionary radiation in which most species lack the tympanic membrane and tympanic annulus, yet the phylogenetic relationships among species in this group remain largely unknown. Here, we present an expanded molecular phylogeny o... Read more

Beamtime and resulting SRμCT data are a valuable resource for researchers of a broad scientific community in life sciences. Most research groups, however, are only interested in a specific organ and use only a fraction of their data. The rest of the data usually remains untapped. By using a new collaborative approach, the NOVA project (Network for Online Visualization and synergistic Analysis of tomographic data) aims to demonstrate, that more efficient use of the valuable beam time is possi...

The Division of Highway and Railway Engineering, Royal Institute of Technology (KTH) promotes advances in computational and experimental science in order to develop new materials, tools and systems for improved mobility, transportation safety and infrastructure durability. The group works on analysis and performance-based design of roads and tracks, management as well as operation and maintenance of roads.

The characterization of the porosity of ground layers in easel paintings: a first step towards understanding its role in water uptake, reactivity and material transport in 19th and early 20th century paintings. The Swiss Institute for Art Research (SIK-ISEA) is studying the studio practice of Swiss painters of the late 19th early 20th century, the materials they used for their paintings, and the deterioration processes the paintings undergo as they age.

Amongst other issues this study... Read more

The imaging beamline, IMX, at LNLS extracts synchrotron radiation from bending magnet D6 with magnetic field of 1.67 T and bending radius of 2.736 m. It has an electron source size of 391 Read more
