Patent number: 11634341Abstract: A nanostructure is provided that in one embodiment includes a cluster of cylindrical bodies. Each of the cylindrical bodies in the cluster are substantially aligned with one another so that their lengths are substantially parallel. The composition of the cylindrical bodies include tungsten (W) and sulfur (S), and each of the cylindrical bodies has a geometry with at least one dimension that is in the nanoscale. Each cluster of cylindrical bodies may have a width dimension ranging from 0.2 microns to 5.0 microns, and a length greater than 5.0 microns. In some embodiments, the cylindrical bodies are composed of tungsten disulfide (WS2). In another embodiment the nanolog is a particle comprised of external concentric disulfide layers which encloses internal disulfide folds and regions of oxide. Proportions between disulfide and oxide can be tailored by thermal treatment and/or extent of initial synthesis reaction.Type: GrantFiled: July 14, 2020Date of Patent: April 25, 2023Assignee: NANOTECH INDUSTRIAL SOLUTIONSInventors: Anna Kossoy, Vladimir Aguf, Alexander Margolin

Patent number: 9080655Abstract: A no-lash nut assembly for installation on a threaded rod and including a lead nut, a trailing nut, a transition nut and a torsion spring. The lead and trailing nuts have threaded bores for mating with the rod. The trailing nut has an external surface configured for engagement with the lead nut to prohibit relative rotation and allow relative axial movement. The transition nut has a threaded bore for mating to trailing nut, an external surface defining a slot, and a front face having a mating surface corresponding to the rear face of the lead nut to allow relative axial movement between the lead nut and the transition nut. The torsion spring has a pin and a hook. The pin protrudes into the rear face of the lead nut and the hook protrudes into the transition nut slot to apply a rotational force on the transition nut.Type: GrantFiled: July 18, 2012Date of Patent: July 14, 2015Assignee: Nook Industries, Inc.Inventors: Patrick M. Cronin, Alexander Margolin, Joseph H. Nook, Jr.

Patent number: 7959891Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanoparticles, comprising feeding a metal precursor selected from metal halide, metal carbonyl, organo-metallic compound and metal oxyhalide vapor into a reaction chamber towards a reaction zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reaction zone being such to enable the formation of the fullerene-like metal chalcogenide nanoparticles product. The present invention further provides novel IF metal chalcogenides nanoparticles with spherical shape and optionally having a very small or no hollow core exhibiting excellent tribological behaviour. The present invention further provides an apparatus for preparing various IF nanostructures.Type: GrantFiled: January 4, 2010Date of Patent: June 14, 2011Assignees: Yeda Research & Development Company Ltd, A.Y.Y.T.

Publication number: 20080170984Abstract: The present invention provides a process for obtaining fullerene-like metal chalcogenide nanospheres, comprising: (a) feeding a metal halide, metal carbonyl, organo-metallic compound or metal oxyhalide vapor into a reacting chamber towards a reacting zone to interact with a flow of at least one chalcogen material in gas phase, the temperature conditions in said reacting zone being such enabling the immediate formation of spherical nucleation seeds of the product; (b) controllably varying the flow of said metal halide, metal carbonyl, organo-metallic compound or metal oxyhalide vapor into said reacting chamber thereby controlling the amount, morphology and size of the so-produced nanospheres, to obtain substantially non-hollow fullerene-like metal calcogenide nanospheres in solid form. The present invention further provides novel IF metal chalcogenides with substantially non-hollow, spherical shape, and having excellent tribological behaviour.Type: ApplicationFiled: April 6, 2006Publication date: July 17, 2008Inventors: Reshef Tenne, Alexander Margolin, Ronit Popovitz-Biro, Lev Rapoport
