TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Nanostructure: The nanostructure (N1) is in combination with at least one other nanostructure, which is inorganic fullerene-like (IF) nanoparticle. The nanostructure (N1) is selected from Mo1-xNbxS2, Mo1-xNbxSe2, W1-xTaxS2, W1-xTaxSe2, MoxWyNb1-x-yS2, MoxWyNb1-x-ySe2, Re1-xWxS2, Ti1-xScxS2, Zr1-xYxS2, Hf1-xLaxS2, Ta1-xHfxS2, Pt1-xIrxS2, Ru1-xMnxS2, Rh1-xRuxS2, Mo1-xRexS2, W1-xRexS2, Re1-xOsxS2, Ti1-xVxS2, Zr1-xNbxS2, Hf1-xTaxS2, Ta1-xWxS2, Pt1-xAuxS2, Ru1-xRhxS2, Rh1-xPdxS2 (preferably Mo1-xNbxS2, Mo1-xRexS2, W1-xRexS2, or W1-xNbxS2, where x is (less than 0.01, preferably less than 0.005)).y=not defined.The nanostructure (N1) is a nanoparticle or nanotube. The nanostructure (N1) has one of the following configurations: atoms of the metal or transition metal B' are incorporated in a lattice of the A'-chalcogenide; or the metal or transition metal B' is distributed uniformly within the nanostructure. The A'-chalcogenide precursor is a semiconductor of a certain electrical conductivity, and the nanostructure has a higher electrical conductivity. The nanostructure (N1) is configured as a donor or acceptor for electrons. In the lubricating material or lubricant composition (C2), the nanostructure is INT, or TF nanoparticle. The lubricating material (C2) comprises MoS2 nanoparticles and nanotubes doped by Nb, and Re; or WS2 nanoparticles and nanotubes doped by Nb, and Re. Preferred Process: In the process (P1), forming the A'-Y1 and B'-Y2 compositions in vapor phase involves evaporating A'-Y1 and B'-Y2 compositions in a chamber separate from the reaction chamber; or evaporating A'-Y1 and B'-Y2 compositions in two chambers, respectively, separate from the reaction chamber. In the process (B) of the process (P1a), the A2-chalcogcnide is provided in the solid phase under conditions permitting phase transformation into the vapor phase. The A2-chalcogenide are nanoparticles selected from INT and IF, and the nanoparticles are prepared by chemical vapor transport (CVT) method. In the process (B) of the process (P1a) the reaction chamber is a two zone chamber, comprising a high temperature zone and a zone of a lower temperature, where the dopant precursor is fed into the high temperature zone and the A2-chalcogenide nanoparticles are fed into the zone of a lower temperature. The maximal temperature of the higher temperature zone is 800 degrees C and the temperature difference between the higher temperature zone and the lower temperature zone exceeds 150 degrees C. Preferred Components: The transport agent of the method (B) of the process (P1a) is iodine. Preferred Definitions:    x=less than 0.005, or 0.005-0.01;    A'=Mo, W, Re, Ti, Zr, Hf, Nb, Ta, Pt, Ru, Rh, In, Ga, and/or alloys such as WxMo1-x;    B'=Si, Nb, Ta, W, Mo, Sc, Y, La, Hf, Ir, Mn, Ru, Re, Gs, V, Au, Rh, Pd, Cr, Co, Fe, or Ni;    chalcogenide=S, Se, or Te.    EXAMPLE - The doping of INT-WS2 (nanotubes) was made in closed quartz ampoule. The ampoule was placed in a two-zone furnace allowing reaction materials to react for different periods of time ( greater than or equal to 18 hours) at different temperatures (800-600 degrees C in relatively cold zone) with the growth zone (hot zone) at less than or equal to 950 degrees C. The temperature gradient was intended to prevent back transport of product. At the end of the reaction, ampoule was cooled by water with ice, to quench reaction at once. The total charge of the INT-WS2 was maximum 250 mg. The stoichiometry determined weight of doping material added to the load. Iodine served as transport agent of dopant atoms. The quartz ampoule containing I2 (less than 1 mg/cm3), ReO3 (at bottom of ampoule) and INT-WS2 (at middle of ampoule) was cooled with liquid nitrogen, evacuated to 10-4 Torr and sealed. The rhenium composition was determined by energy dispersive X-ray spectroscopy (EDS) analyzer mounted on both scanning electron microscope (SEM) and transition electron microscope (TEM). The nanotubes appeared to be very similar to the undoped ones in terms of crystalline perfection, but they were somewhat more sensitive to beam damage. In another related experiment, ReCl4 was placed in bottom of ampoule (instead of ReO3). This experiment led to improved doping characteristics of nanotubes. The reason being that not only Re but also chlorine served as n-type dopant, due to substation of tungsten atoms in nanotube lattice.
