Two dimensional forms of silicon offer different conductive properties to that of the bulk material, promising applications in new electronic technologies. Here, the authors report the fabrication of bilayer silicenes which, unlike their monolayer fo

We report the synthesis of organosilica nanotubes containing 2,2′-bipyridine chelating ligands within their walls, employing a single-micelle-templating method. These nanotubes have an average pore diameter of 7.8 nm and lengths of several hundred
