Discrimination of dynamically and post ‐dynamically recrystallized grains based on EBSD data: application to Inconel 718
SummaryThe importance of angular resolution in EBSD analyses is discussed based on an Inconel 718 sample containing several populations of recrystallized grains, with subtle differences in dislocation contents. Classical EBSD analyses (with angular resolution in the range of 0.5 –1°) do not allow for distinguishing recrystallized grains grown dynamically or post‐dynamically. The angular resolution of EBSD orientation and misorientation data can be significantly improved (down to about 0.1–0.2°) either using more sophisticated Kikuchi pattern indexing methods and/or using the recently proposed LLASS denoising filter...

The 3D imaging of mesenchymal stem cells on porous scaffolds using high ‐contrasted x‐ray computed nanotomography
This study presents an X ‐ray computed nanotomography (nano‐CT) based, high‐resolution imaging technique. Thanks to a voxel resolution of 540 nm, this novel technique is suitable for observing the 3D morphology of soft biopolymeric scaffolds seeded with stem cells. A sample of highly porous collagen scaffold seeded w ith contrasted mesenchymal stem cells (MSC) was investigated by using lab‐based nano‐CT. The whole volume of the sample was analysed without its destruction. To evaluate the potential of nano‐CT, a comparison measurement was done using a standard microscopy technique. Scanning electron microsc opy...

A stochastic microstructure model for particle reinforced aluminium matrix composites
SummaryMetal matrix composites are complex materials consisting of various phases which can display largely different mechanical properties. The deformation behaviour of these composites cannot be sufficiently modelled by averages or simple particle shapes due to the local stresses that occur on the particle edges. Therefore, a sophisticated model of the microstructure is needed. We introduce a method for stochastic modelling of a silicon carbide (SiC) particle reinforced aluminium matrix composite. The SiC particles are modelled by Laguerre polyhedra generated by densely packed spheres. The shape factors of the polyhedra ...

Effects of object ‐to‐detector distance and beam energy on synchrotron radiation phase‐contrast imaging of implanted cochleae
ConclusionsThe results of this study show that SR ‐PCI is a viable method to visualize implanted human cochleae. SR‐PCI is less invasive, less labour intensive and is associated with a much lower acquisition time compared to other methods for postimplantation imaging in humans, such as histological sectioning. We found that the optimal combinat ion of E and ODD parameters was 72 keV and 2 m, respectively. These parameters resulted in high‐contrast images of the electrode as well as all internal structures of the cochleae.Lay DescriptionCochlear implants (CI) are currently the preferred method of treatment for hearing...

FIB ‐SEM imaging properties of Drosophila melanogaster tissues embedded in Lowicryl HM20
In this study we explored the applicability of an electron lucent resin, Lowicryl HM 20, for focused ion beam scanning electron microscopy. The Lowicryl embedding workflow operates at milder chemical treatments and lower temperatures, thus preserving the sub‐cellular and su b‐organellar organization, as well as fluorescent markers visible by light microscopy. Here we show that focus ion beam scanning electron microscopy of Lowicryl‐embedded fruit flies tissues provides reliable imaging revealing fine structural details. Our workflow benefited from use of transmissi on electron microscopy for the quality control of th...

Open Source 3D ‐printed focussing mechanism for cellphone‐based cellular microscopy
SummaryThe need to improve access to microscopes in low ‐resource and educational settings coupled with the global proliferation of camera‐enabled cellphones has recently led to an explosion in new developments in portable, low‐cost microscopy. The availability of accurate ball lenses has resulted in many variants of van Leeuwenhoek‐like microsco pes. Combined with cellphones, they have the potential for use as portable microscopes in education and clinics. The need for reproducibility in such applications implies that control over focus is critical. Here, we describe a 3D‐printed focussing mechanism based on a r...

Influence of the crosstalk on the intensity of HAADF ‐STEM images of quaternary semiconductor materials
SummaryThe influence of the neighbouring atomic ‐columns in determining the composition at atomic column scale of quaternary semiconductor compounds, using simulated HAADF‐STEM images is evaluated. The InAlAsSb alloy, a promising material in the photovoltaic field, is considered. We find that the so called ‘crosstalk’ effect plays an impo rtant role for the aimed compositional determination. The intensity transfer is larger from neighbouring atomic columns with higher average Z, and towards atomic columns with smaller Z. Our results show that in order to obtain precise information on the column composition, the HAA...
