Understanding the near-threshold crack growth behavior in an aluminum alloy by x-ray tomography

Understanding the near-threshold crack growth behavior in an aluminum alloy by x-ray tomography

The near-threshold behavior of long cracks is evaluated using pre-cracked flat dogbone specimens of a commercial aluminum alloy in two heat treatment states. Once the threshold was known, the crack initially introduced by cyclic compression was propagated under load control with approximately
constant range of the stress intensity factor at values close to the threshold values. The 3D morphology of the crack and the spatial distribution of the primary precipitates obtained by µ-CT were... Read more

3D characterization of the fracture mechanisms of a Fe-rich Al-Si-Cu alloy

3D characterization of the fracture mechanisms of a Fe-rich Al-Si-Cu alloy

The effect of the defect size and morphology on the fatigue damage evolution was analysed in a recycled Al-Si-Cu alloy by micro-computed tomography and scanning electron microscopy. Fatigue tests were performed and the different crack initiation scenarios were characterized and classified. The interaction between shrinkage and gas pores was the key crack initiation mechanism and the ß-Al5FeSi particles did not play any role in the crack initiation phase. However, crack path analysis indicate... Read more

Mechanical adaptation of trabecular bone morphology in the mammalian mandible

Mechanical adaptation of trabecular bone morphology in the mammalian mandible

Alveolar bone, together with the underlying trabecular bone, fulfils an important role in providing structural support against masticatory forces. Diseases such as osteoporosis or periodontitis cause alveolar bone resorption which weakens this structural support and is a major cause of tooth loss. However, the functional relationship between alveolar bone remodelling within the molar region and masticatory forces is not well understood. This study investigated this relationship by comparing m... Read more

3D Reconstruction of Lipid Droplets in the Seed of Brassica napus

3D Reconstruction of Lipid Droplets in the Seed of Brassica napus

Rapeseed is one of the most important and widely cultured oilseed crops for food and nonfood purposes worldwide. Neutral lipids are stored in lipid droplets (LDs) as fuel for germination and subsequent seedling growth. Most of the LD detection in seeds was still in 2D levels, and some of the details might have been lost in previous studies. In the present work, the configuration of LDs in seeds was obtained by confocal imaging combined with 3D reconstruction technology in Brassica napus<... Read more

3-D micro-architecture and mechanical response of soil cemented via microbial-induced calcite precipitation

3-D micro-architecture and mechanical response of soil cemented via microbial-induced calcite precipitation

We introduce the application of microbial-induced calcite precipitation via the ureolytic soil bacterium Sporosarcina Pasteurii in freeze-dried form, as a means of enhancing overall MICP efficiency and reproducibility for geotechnical engineering applications. We show that the execution of urea hydrolysis and CaCO3 precipitation persist as a “cell-free” mechanism upon the complete breakdown of rehydrated cell clusters. Further, strength and stiffness parameters of bio-cemented ... Read more

Synchrotron X-ray tomographic quantification of microstructural evolution in ice cream – a multi-phase soft solid

The microstructure of food affects our sensorial perception, its attractiveness, and the manufactured product’s shelf-life.

Microstructural evolution in soft matter directly influences not only the material’s mechanical and functional properties, but also our perception of that material’s taste. Using synchrotron X-ray tomography and cryo-SEM we investigated the time–temperature evolution of ice cream’s microstructure. This was enabled via three adv... Read more

Morphology and ontogeny of Lophopus crystallinus lophophore support the epistome as ancestral character of phylactolaemate bryozoans

Phylactolaemate bryozoans are the sister-group to all remaining bryozoan taxa. Consequently, their study is essential to reveal and analyze ancestral traits of Phylactolaemata and Bryozoa in general.

They are the only bryozoans to possess an epistome which traditionally has been regarded as shared with phoronids and brachiopods. Contrary to older observations, an epistome was recently reported to be missing in the early branching phylactolaemate Lophopus crystallinus. In this... Read more
