Journal ArticleDOI
High-Rate, Gas-Phase Growth of MoS2 Nested Inorganic Fullerenes and Nanotubes
TL;DR: The gas-phase reaction between MoO3-x and H2S in a reducing atmosphere at elevated temperatures (800� to 950�C) has been used to synthesize large quantities of an almost pure nested inorganic fullerene (IF) phase of MoS2, obtaining a uniform IF phase with a relatively narrow size distribution.
Journal ArticleDOI
Stress-induced fragmentation of multiwall carbon nanotubes in a polymer matrix
TL;DR: In this article, the authors report the observation of single nanotube fragmentation, under tensile stresses, using nanotubes-containing thin polymeric films, and they estimate that the multi-wall multi-nanotube-matrix stress transfer efficiency is at least one order of magnitude larger than in conventional fiber-based composites.
Journal ArticleDOI
Hollow nanoparticles of WS2 as potential solid-state lubricants
TL;DR: In this article, hollow nanoparticles (HNs) of metal dichalcogenides MX2 have been used as solid lubricants to reduce wear in situations where the use of liquid lubricants is either impractical or inadequate, such as in vacuum, space technology or automotive transport.
Journal ArticleDOI
Tribological properties of WS2 nanoparticles under mixed lubrication
Lev Rapoport,V. Leshchinsky,Igor Lapsker,Yu Volovik,O. Nepomnyashchy,M. Lvovsky,Ronit Popovitz-Biro,Yishay Feldman,Reshef Tenne +8 more
TL;DR: In this paper, the effect of the IF in oil was studied using pin-on-disk tester in the regime of mixed lubrication and the interaction between the full film and the asperity contact fractions has been considered and the time evolution of the friction force was evaluated.
Journal ArticleDOI
Inorganic fullerene-like material as additives to lubricants: structure–function relationship
Lev Rapoport,Yishay Feldman,M. Homyonfer,Hagai Cohen,Jeremy Sloan,John L. Hutchison,Reshef Tenne +6 more
TL;DR: In this paper, inorganic fullerene-like (IF) supramolecules of metal dichalcogenide MX2 (M=Mo, W, etc.; X=S, Se), materials with structures closely related to (nested) carbon fullerenes and nanotubes have been synthesized.
