“…One-dimensional nanoparticles, whose aspect ratiodefined by the ratio of length to diameteris much higher than one, are the subject of intensive research as interesting building blocks for hierarchical assembly of functional nanostructures. , In many cases, their colloidal properties are a crucial aspect for their use. For instance, aqueous two-phase extraction-based separation of surfactant dispersed carbon nanotubes, which are iconic objects of nanoscience, is experiencing constant progress. , It should also be noted that the colloidal properties of clay nanotubes, a unique class of nanostructured materials, are considered in environmental and industrial applications. , Among them, synthetic imogolite nanotubes (INTs) , constitute a specific case of inorganic hollow nanostructures, truly nanometric in diameter. Understanding water organization around and inside INTs represents an essential step for a wide range of applications, such as catalytic and photocatalytic nanoreactors, liquid crystals, , or water depollution .…”
