    9 April 2017 A new paper by Clément Levard has just been accepted at RSC advances the 9th April 2017. The title is : "Alignment of Ge-imogolite nanotubes in isomalt with tunable inter-tube distance". This article explain a very clever idea of Clément Levard on the use of a melted sugar to align perfectly imogolite nanotubes. Upon cooling the sugar enables the organisation to be fixed. It will for sure be the basis of very interesting future research. Hope you will enjoy this paper. availbale soon: DOI: 10.1039/c7ra01380a

    11 March 2017 An article entitled "A mechanism for the sphere/​tube shape transition of nanoparticles with an imogolite local structure (imogolite and allophane)" has just been accepted for publication in Applied Clay Science.
    In this paper, we have used a simple nano-mechanical model which shows that the proto-imogolite having an Imogolite Local Structure (ILS) adopt different curvature depending on their size. We argue that this could play a role in the formation of tubular ILS (imogolite and imogolite-like) and/or spherical ILS (some sort of allophane).
    By the way, we also show in this article that the imogolite structure is oriented (not symmetric upon 180° rotation). This is of fundamental importance for tip-tip growth process. To our knowledge it was not really discussed in the research papers about imogolite up to now.
    We hope you will find this article useful and we would be really happy to have any comments and discussion.

    12 December 2016 After one year of renovation, the SAXS equipments of the LIONS are about to restart. The installation of a new set-up, shared with LLB, is a great event for the lab and will extend the characterization possibilities.

    November 2016 synthetic imogolite samples have been send to Pr Peng Yuan in China. Hope this will be the starting point of a fruitful collaboration.

    As a co-editor and (co-)author of three chapters, this book has kept me busy a lot lately. The result is very good and I hope many of you will find this book useful.
    Just for the anecdote, the nice 3D image of a mixed imogolite/halloysite was inspired by a discussion at a corridor whiteboard of Faïza's laboratory in Orleans and by a stone lying in Borée (in France).

    Samples (only for research purpose) are available upon request in the framework of scientific collaborations. The conditions can be discussed directly with Antoine Thill (

    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.

    14 October 2013 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!

    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.
