INORGANIC NANOTUBES AND FULLERENE-LIKE NANOPARTICLES

Computer Engineering electronics Engineering Civil Engineering

This presentation is aimed at underlying the principles, synthesis, characterization and applications of inorganic nanotubes (INT) and fullerne-like (IF) nanoparticles from 2-D layered compounds. While the high temperature synthesis and study of IF materials and INT from layered metal dichalcogenides, like WS2 and MoS2 remain a major challenge, progress with the synthesis of IF and INT structures from various other compounds has been realized, as well. Intercalation and doping of these nanostructures, which lends itself to interesting electronic properties, has been realized, too. Recently, new core-shell nanotubular structures, like PbI2@WS2 nanotubes, have been reported. Doping of the IF and INT endow them with interesting electrical properties. Major progress has been achieved in elucidating the structure of INT and IF using advanced microscopy techniques, like aberration corrected TEM with 0.08 nm resolution and electron tomography. Also recently, scaling up efforts in collaboration with "NanoMaterials" resulted in multikilogram production of (almost) pure multiwall WS2 nanotubes phases. loading..
