3D imaging of microstructure of spruce wood.
Pavel Trtik,Jürg Dual,Daniel Keunecke,David Mannes,Peter Niemz,P Stähli,Anders Kaestner,Amela Groso,Marco Stampanoni +8 more
TL;DR: Synchrotron radiation phase-contrast X-ray tomographic microscopy was applied to observation and identification of the features of spruce anatomy at the cellular lengthscale and it is suggested that the position of sub-voxel-sized features can be determined indirectly using watershed segmentation.
Journal ArticleDOI
Gas Evolution in Operating Lithium-Ion Batteries Studied In Situ by Neutron Imaging.
Barbara Michalak,Heino Sommer,David Mannes,Anders Kaestner,Torsten Brezesinski,Jürgen Janek,Jürgen Janek +6 more
TL;DR: The results suggest that metal dissolution in the electrolyte and decomposition products resulting from the high potentials adversely affect the gas generation, particularly in the first charge cycle (i.e., during graphite solid-electrolyte interface layer formation).
Journal ArticleDOI
Visualization and quantification of liquid water transport in softwood by means of neutron radiography
Marjan Sedighi-Gilani,Michele Griffa,David Mannes,Eberhard Lehmann,Jan Carmeliet,Dominique Derome +5 more
TL;DR: In this paper, the authors investigated liquid water uptake in an orthotropic, cellular, hierarchical and natural material namely wood using neutron radiography and found that latewood cells play a more significant role in water uptake than earlywood cells and that ray tracheids also contribute to liquid transport.
Journal ArticleDOI
Olive tree-ring problematic dating: a comparative analysis on Santorini (Greece)
Paolo Cherubini,Turi Humbel,Turi Humbel,Hans Beeckman,Holger Gärtner,David Mannes,Charlotte Pearson,Charlotte Pearson,Werner Schoch,Roberto Tognetti,Simcha Lev-Yadun +10 more
TL;DR: Dendrochronological analyses of olive trees growing on the Aegean island Santorini (Greece) show that the determination of the number of tree-rings is impossible because of intra-annual wood density fluctuations, variability in tree-ring boundary structure, and restriction of its cambial activity to shifting sectors of the circumference, causing the tree- ring sequences along radii of the same cross section to differ.
Journal ArticleDOI
Chasing quantitative biases in neutron imaging with scintillator-camera detectors: a practical method with black body grids
Pierre Boillat,Chiara Carminati,Florian Schmid,Christian Grünzweig,Jan Hovind,Anders Kaestner,David Mannes,M. Morgano,Muriel Siegwart,Pavel Trtik,Peter Vontobel,Eberhard Lehmann +11 more
TL;DR: The results show that a reduction of the quantification bias can be obtained, up to one order of magnitude, for moderately transparent samples, and little sensitivity is observed to the parameters used for the correction.
