Morphological evolution and internal strain mapping of pomelo peel using X-ray computed tomography and digital volume correlation

Morphological evolution and internal strain mapping of pomelo peel using X-ray computed tomography and digital volume correlation

Among natural cellular materials, pomelo peels, having a foam-like hierarchical microstructure, represent an ideal model for developing materials with high energy absorption efficiency. In this work, by combining X-ray tomographic imaging technique and digital volume correlation (DVC), in-situ stepwise uniaxial compression tests were performed to quantify the internal morphological evolution and kinematic responses of pomelo peel samples during compression.

Organism motility in an oxygenated shallow-marine environment 2.1 billion years ago

Organism motility in an oxygenated shallow-marine environment 2.1 billion years ago

Evidence for macroscopic life in the Paleoproterozoic Era comes from 1.8 billion-year-old (Ga) compression fossils [Han TM, Runnegar B (1992) Science 257:232–235; Knoll et al. (2006) Philos Trans R Soc Lond B 361:1023–1038],  Stirling biota [Bengtson S et al. (2007) Paleobiology 33:351–381], and large colonial organisms exhibiting signs of coordinated growth from the 2.1-Ga Francevillian series, Gabon. Here we report on pyritized string-shaped structures from... Read more

GEVES uses Avizo software to study and control plant seeds

GEVES uses Avizo software to study and control plant seeds

At GEVES, Microtomography (micro-CT), which is a technique using X-rays to investigate internal anatomy and morphology of organisms without destruction, is applied to plant seed quality control and phenotyping. Several applications have been developed using micro-CT coupled with Avizo software development, such as for example in the Measurements of internal and external sugar beet seed structures for seed phenotyping

Modelling deformation and fracture in confectionery wafers

Modelling deformation and fracture in confectionery wafers

The aim of this research is to model the deformation and fracture behaviour of brittle wafers often used in chocolate confectionery products.

Three point bending and compression experiments were performed on beam and circular disc samples respectively to determine the ‘apparent’ stress-strain curves in bending and compression. The deformation of the wafer for both these testing types was observed in-situ within an SEM. The wafer is modelled analytically and numerically as a composi... Read more

Air-entrained Concrete: Relationship between Thermal Conductivity and Pore Distribution Analyzed by X-Ray Tomography

Air-entrained Concrete: Relationship between Thermal Conductivity and Pore Distribution Analyzed by X-Ray Tomography

The thermal conductivity values of ordinary concrete can be adjusted to those prescribed in constructions by entraining air bubbles to reduce the density of concrete in order to achieve good thermal insulation. This paper concerns the analysis of air bubble distribution in concrete obtained by micro X-ray µCT (computed tomography) and correlates it with its thermal conductivity (k). (…) The results show that air-entrainment leads to viable use of this material as sealer to achieve good... Read more

RF-induced heating in tissue near bilateral DBS implants during MRI at 1.5 T and 3T: The role of surgical lead management

RF-induced heating in tissue near bilateral DBS implants during MRI at 1.5 T and 3T: The role of surgical lead management

Access to MRI is limited for patients with DBS implants due to safety hazards, including radiofrequency heating of tissue surrounding the leads. Computational models provide an exquisite tool to explore the multi-variate problem of RF implant heating. We used a computational approach to assess RF heating around tips of bilateral DBS leads during MRI at 1.5T and 3T using realistic DBS lead models. A substantial difference was found between the SAR and temperature rise at the tip of right and l... Read more

Air bubbles in calcium caseinate fibrous material enhances anisotropy

Air bubbles in calcium caseinate fibrous material enhances anisotropy

Dense calcium caseinate dispersions can be transformed into hierarchically fibrous structures by shear deformation. This transformation can be attributed to the intrinsic properties of calcium caseinate. Depending on the dispersion preparation method, a certain amount of air gets entrapped in the sheared protein matrix. Although anisotropy is obtained in the absence of entrapped air, the fibrous appearance and mechanical anisotropy of the calcium caseinate materials are more pronounced with... 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

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

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

Microstructural Characterization of Fried Potato Disks Using X‐Ray Micro Computed Tomography

Microstructural Characterization of Fried Potato Disks Using X‐Ray Micro Computed Tomography

Microstructural properties play a key role to affect oil uptake and product quality during frying of foods. The objective of this study was to observe the complex microstructural changes and mass transfer mechanisms in potato disks during frying.

The potato disks of 1.65 mm thickness were fried at 190 °C for 0, 20, 40, 60, and 80 s. X‐ray micro‐computed tomography (CT) was used for 3‐dimensional (3D) imaging of microstructure of porous potato disks. Total porosity, pore size dis... Read more

Unilever uses Avizo software to visualize and understand food and detergent structures

Unilever uses Avizo software to visualize and understand food and detergent structures

Food and detergent products are composed of complex micro structures. With modern microscopic techniques we can make them visible. The microstructure greatly affects macroscopic properties such as appearance, taste, mouth feel and solubility. Making these structures visible and quantifying them is essential to the development of products with optimal product properties. A broad range of imaging techniques is used to visualize microstructure elements at different length scales. For example, X-... Read more
