Because the two-fold surface is  periodic in one direction and aperiodic (with a  quasiperiodicity related to the Fibonacci sequence) in the perpendicular direction, frictional anisotropy  is not unexpected; however, the magnitude of that  anisotropy in the Park experiment, a factor of eight,  is unprecedented. By eliminating chemistry as a  variable, the experiment also demonstrated that the  low friction of quasicrystals must be tied in some  way to their quasiperiodicity. Through various  models, we investigate generic geometric mechanisms  that might give rise to this anisotropy.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9783843394017\"\u003e\u003ch3\u003eAn Investigation of the Tribological Properties of Quasicrystals and Quasiperiodic Surfaces\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9783843394017","offer_id":39497050652765,"sku":"9783843394017","price":49.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/f4e15d58-48b1-47ae-8021-4d15613d968c.jpg?v=1773296383","url":"https:\/\/shop.autorenwelt.de\/products\/toward-understanding-low-surface-friction-on-quasiperiodic-surfaces-von-keith-mclaughlin","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
