I have to write a small paper on quasicrystals... anyone know where I can find free-access books and scientific journal papers on this topic?
Quasicrystals are a type of solid material that have a unique atomic structure that is ordered, but not periodic. This means that they have a repeating pattern, but it is not a simple, regular pattern like other crystals.
Regular crystals have a periodic, repeating pattern of atoms, while quasicrystals have a non-repeating, but still ordered, pattern. Regular crystals also have rotational symmetry, while quasicrystals have multiple axes of symmetry.
Quasicrystals have unique physical and mechanical properties, such as high strength and low friction, that make them useful in various industries. They have potential applications in technologies such as coatings, electronics, and even biomedical devices.
Scientists use various techniques such as X-ray diffraction and electron microscopy to study the atomic structure of quasicrystals. They also conduct experiments to measure their physical and mechanical properties.
Both. Some quasicrystals have been found in nature, such as in certain types of meteorites. However, most quasicrystals are created in laboratories through controlled synthesis methods.
