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: 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 […]
