Imaging Methods for Analyzing Adhesion in Extrusion Coating

Surface and Interface Analysis, EarlyView.
ABSTRACT Extrusion coating is a common method to produce materials for the packaging industry. One of the most important properties in extrusion‐coated structures is adhesion between the substrate and the coating. Analyzing adhesion of samples produced by extrusion coating in a standardized way can be challenging, and especially, quantitative data are ...

Integration of Micro‐CT and XRF Mapping for Multimodal 3D Analysis of Polychrome Wooden Artifacts

X-Ray Spectrometry, EarlyView.
ABSTRACT Over the past 5 years, computer applications have become crucial to archeological research. Since the 1990s, the focus has transitioned from data management tools to the development of virtual models. Recently, digital documentation of cultural heritage has gained considerable focus, with 3D modeling of objects.

Microfocus X-ray imaging of Brazil nuts for quality control

Semina: Ciências Agrárias, 2015
Non-destructive quality assessment of food prior to processing is desirable in commercial facilities due to its non-invasive nature, for economic reasons and for its safety appeals. Grading Brazil nuts in this way allows for the separation of undesirable

Paired CycleGAN‐based virtual staining for 3D X‐ray histology of bone‐implant systems

Journal of Synchrotron Radiation, EarlyView.
This work demonstrates virtual staining for 3D X‐ray histology using a modified CycleGAN trained on paired synchrotron radiation microtomography (SR‐µCT) and histology images of bone‐implant specimens. The method enables the generation of artificially coloured contrast resembling conventional histological staining from label‐free SR‐µCT data and is ...
