Using mathematics for construction and analysis of quasicrystal structures is a difficult task. Computer modeling, based on the existing theories of quasicrystals, however, greatly facilitated this task. Advanced programs have been developed [52] allowing one to construct, visualize and analyze quasicrystal structures and their diffraction ...
Vibrational modes in a quasicrystal associated with atomic rearrangements crystal lattice Phoniton: A theoretical quasiparticle which is a hybridization of a localized, long-living phonon and a matter excitation [15] phonon Phonon: Vibrational modes in a crystal lattice associated with atomic shifts crystal lattice Phonon polariton
Nickel's (1995) formal definition explicitly mentioned crystallinity as a key to defining a substance as a mineral. [126] A 2011 article defined icosahedrite, an aluminium-iron-copper alloy as mineral; named for its unique natural icosahedral symmetry, it is a quasicrystal. Unlike a true crystal, quasicrystals are ordered but not periodic. [137 ...

This article provides a list of autoimmune diseases. These conditions, where the body's immune system mistakenly attacks its own cells, affect a range of organs and systems within the body. Each disorder is listed with the primary organ or body part that it affects and the associated autoantibodies that are typically found in people diagnosed ...
The term hyperuniformity (also independently called super-homogeneity in the context of cosmology [22]) was coined and studied by Salvatore Torquato and Frank Stillinger in a 2003 paper, [1] in which they showed that, among other things, hyperuniformity provides a unified framework to classify and structurally characterize crystals, quasicrystals, and exotic disordered varieties.
A rare disease is technically defined (in the European Union) as a disease that is found in fewer than 5 people per every 10,000 people. ...
