  2. Quasicrystal - Wikipedia

    en.wikipedia.org/wiki/Quasicrystal

    It does not corrode and is extremely strong, suitable for razor blades and surgery instruments. The small quasicrystalline particles impede the motion of dislocation in the material. [65] Quasicrystals were also being used to develop heat insulation, LEDs, diesel engines, and new materials that convert heat to electricity. Shechtman suggested ...

  3. Quasiparticle - Wikipedia

    en.wikipedia.org/wiki/Quasiparticle

    In materials, a photon quasiparticle is a photon as affected by its interactions with the material. In particular, the photon quasiparticle has a modified relation between wavelength and energy (dispersion relation), as described by the material's index of refraction. It may also be termed a polariton, especially near a resonance of the material.

  5. Quasi-solid - Wikipedia

    en.wikipedia.org/wiki/Quasi-solid

    Quasi-solid, Falsely-solid, or semisolid is the physical term for something whose state lies between a solid and a liquid.While similar to solids in some respects, such as having the ability to support their own weight and hold their shapes, a quasi-solid also shares some properties of liquids, such as conforming in shape to something applying pressure to it and the ability to flow under pressure.

  6. Quasicrystals and Geometry - Wikipedia

    en.wikipedia.org/wiki/Quasicrystals_and_Geometry

    The book is divided into two parts. The first part covers the history of crystallography, the use of X-ray diffraction to study crystal structures through the Bragg peaks formed on their diffraction patterns, and the discovery in the early 1980s of quasicrystals, materials that form Bragg peaks in patterns with five-way symmetry, impossible for a repeating crystal structure.

  7. Dirac matter - Wikipedia

    en.wikipedia.org/wiki/Dirac_matter

    A topological insulator is a material that behaves as an insulator in its interior (bulk) but whose surface contains conducting states. This property represents a non-trivial, symmetry protected topological order. As a consequence, electrons in topological insulators can only move along the surface of the material.

  8. Quasi-crystals (supramolecular) - Wikipedia

    en.wikipedia.org/wiki/Quasi-crystals_(supra...

    Quasi-crystals are supramolecular aggregates exhibiting both crystalline (solid) properties as well as amorphous, liquid-like properties.. Self-organized structures termed "quasi-crystals" were originally described in 1978 by the Israeli scientist Valeri A. Krongauz of the Weizmann Institute of Science, in the Nature paper, Quasi-crystals from irradiated photochromic dyes in an applied ...

  9. Subtle body - Wikipedia

    en.wikipedia.org/wiki/Subtle_body

    A subtle body is a "quasi material" [1] aspect of the human body, being neither solely physical nor solely spiritual, according to various esoteric, occult, and mystical teachings. This contrasts with the mind–body dualism that has dominated Western thought.
