Israeli researchers from the Weizmann Institute of Science and Schenkar Engineering have enhanced the structure of epoxy glue with nanotechnology to generate a product with double the binding strength of conventional adhesives for aerospace industry applications. The scientists added minuscule particles of tungsten sulfide (WS2) to conventional glue at concentrations of 0.5 percent. Thus far, nanostructured WS2 has been used for the chemical storage of hydrogen and the metal lithium, material for solid-state secondary lithium battery cathodes, as well as a dry lubricant and as catalyst in hydrodesulfurization of crude oil. The research team projects that the nano-glue will be helpful to aviation and space engineers in the development of new vehicles in the atmosphere and beyond. They say the material also can be useful to engineers in numerous other industries.
