Metal-dichalcogenide, inorganic

Electron beam irradiation and laser ablation has been successful in producing the metal dichalcogenide nanotubes. Laser ablation of MoS2 and WS2 targets produces substantial amounts of inorganic fullerenes and nanotubes.64 Electron beam irradiation of bulk WS2 powder yields various nanostructures of WS2 including inorganic fullerenes, nanotubes and nanorods.65... 

Several layered inorganic compounds possess structures comparable to the structure of graphite, the metal dichalcogenides (sulfides, selenides, and tellurides),... 

Dr. H.J.M. Bouwmeester. After studying chemistry at the University of Croningen (the Netherlands), Dr. Bouwmeester received his degree in inorganic chemistry in 1982. He received his Ph.D. degree at the same university on the basis of a dissertation titled Studies in Intercalation Chemistry of Some Transition Metal Dichalcogenides. For three years he was involved with industrial research in the development of the ion sensitive field effect transistor (ISFET) for medical application at Sentron V.O.F. in the Netherlands. 

Several types of nanoparticles can be envisaged as lubricant additives. The chapters of this book describe different possible nanolubricants nested nanoparticles (fuUerenes, onions and nanotubes) made on metal dichalcogenides or carbon, reverse overbased micelles, metallic nanoparticles and boron-based nanolubricants. In some cases, the authors chose to study these particles because their structure is close to well-known lamellar structures in tribology (for example inorganic fuUerenes of M0S2). However, dispersion of nanoparticles in oil is not always simple. Thus, in a first part, some rules will be shown about the dispersion of solid nanoparticles in a liquid. 

Layered compounds, in particular the transition-metal dichalcogenides (TMDs) and transition-metal oxides (TMOs), can be intercalated with a wide range of both organic and inorganic materials which may have a profound influence on the physical properties of the host compound [1]. The intercalation reaction in these compounds is driven by charge transfer from the intercalant to the host layered compound conduction band and thus electron-donating species can take place in such a reaction. The reversible ion-electron transfer reaction is classically represented by the scheme ... 

It is clear that the metal dichalcogenides are amenable to the formation of a variety of epitaxial organic and inorganic overlayers, with formation of coincident lattices facilitated by the weak interactions of the basal planes of these materials with...
