Synthesis and growth mechanism of hybrid imogolite nanotubes
|8 Avril 2014||
A new paper is published in J. Phys. Chem. C. on the deformation of imogolite nanotube upon drying.|
Thanks to a systematic method developed to analyze X-ray scattering diagrams as a function of the nanotube shape, single-walled germanium-based imogolite nanotubes, known as cylindrical for more than thirty years, are shown to take an hexagonal base shape when arranged in bundles.

A new paper is published in Chem. Comm. on the synthesis of micron long Germanium based imogolite nanotubes.|
Up to now the length of Germanium based nanotubes was limited to less than 100 nm. We are now able to go far beyond this limit. Together with the high concentration yield, this is making the Ge-Imogolite an exceptional nanotube!

"How the Diameter and Structure of (OH)3Al2O3SixGe1-xOH Imogolite Nanotubes are Controlled by an Adhesion vs Curvature Competition"
Inspired by the pioneering work of Wada in 1982, we have revisited the structural modifications obtained when Germanium is introduced in the Imogolite wall structure.
In light of the recent discovery of the multi-wall Ge-imogolite structures, we came across some new surprises. I hope you will have a nice time reading this article.
