Advances in synchrotron radiation microtomography

Scripta Materialia, 2006
Abstract The use of synchrotron radiation X-ray microtomography rests on the exploitation of the beam coherence, the high spatial (submicron) or temporal resolution (s), in situ and real time experiments and quantitative measurements. Selected original applications showing these capabilities are presented.

3D multiscale imaging of human vocal folds using synchrotron X-ray microtomography in phase retrieval mode

Scientific Reports, 2018
Human vocal folds possess outstanding abilities to endure large, reversible deformations and to vibrate up to more than thousand cycles per second. This unique performance mainly results from their complex specific 3D and multiscale structure, which is ...

Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

Plant, Cell &Environment, EarlyView.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

Local and Global relations between the number of contacts and density in monodisperse sphere packs

, 2006
The topological structure resulting from the network of contacts between grains (\emph{contact network}) is studied for large samples of monosized spheres with densities (fraction of volume occupied by the spheres) ranging from 0.59 to 0.64.

Gold nanoparticles for X-ray microtomography of neurons.

ACS Chemical Neuroscience, 2019
Commonly used methods to visualize the biological structure of brain tissues at subcellular resolution are confocal microscopy and two-photon microscopy. Both require slicing the sample into sections of a few tens of micrometers.
