Author: C. Geantet Instit: Lyon Scientific Research Institute of Catalysis and the Environment A quasi-crystalline catalyst for steam reforming of methanol is a catalyst based on quasi-crystalline materials that have special properties compared to conventional crystalline materials. The quasi-crystalline catalysts used in the production of hydrogen have shown high efficiency. Hydrogen is a clean and […]

Author: NK Mukhopadhyay Instit: Department of Metallurgical Engineering, Indian Institute of Technology (Banaras Hindu University) Quasicrystals are a new type of materials with a low coefficient of friction. These unusual structures violate the rule of periodicity of the crystal lattice, but retain some of its features. Due to this, quasicrystals have unique physical properties that […]

Author: A.A. Lepeshev, E.A.Rozhkova, I.V. Karpov, A.V.Ushakov, L.Y.Fedorov Instit: Siberian Federal University Quasi-crystalline alloys, characterized by an unusual quasi-periodic structure and a fifth-order symmetry axis ”forbidden“ in crystallography, have a unique set of chemical and physico-mechanical properties. In this regard, the quasi−crystalline alloys of the Al−Cu—Me system (where Me is Fe, Cr, Mn, V) are […]

Author: T Grenet a, F Giroud a, C Loubet a, J.L Joulaud b, M Capitan b Instit: LEPES-CNRS, BP166, 38042 Grenoble cedex 9, France Quasicrystals are unique structures in which atoms are arranged in unusual and non-repeating patterns. The study of the formation of quasicrystals in metallized layers of aluminum, copper and iron is an […]
