prevent crystallization from occurring, such as antifreeze proteins. An ideal crystal has every atom in a perfect, exactly repeating pattern. However, in...

at room temperature, and to the hexagonal crystal system above 573 °C (846 K; 1,063 °F). The ideal crystal shape is a six-sided prism terminating with...

always an ideal crystal, and that other, more complex structures could also exist. These structures were later classified as aperiodic crystals, and their...

is a type of persistent magnetic state in ideal crystals. Altermagnetic structures are collinear and crystal-symmetry compensated, resulting in zero net...

this condition is often applied in solid state physics to model an ideal crystal. Born and von Karman published a series of articles in 1912 and 1913...

the crystal habit is an external representation of the internal ordered atomic arrangement. Most natural crystals, however, do not display ideal habits...

varies from crystals with ideal crystal shapes (euhedral) to irregular crystals (anhedral), whether the rock shows highly nonuniform crystal sizes (is porphyritic)...

supposed that vacancies – empty sites normally occupied by particles in an ideal crystal – lead to supersolidity. These vacancies are caused by zero-point energy...

materials science, a single crystal (or single-crystal solid or monocrystalline solid) is a material in which the crystal lattice of the entire sample...

particular ideal crystal structure, all distances are geometrically related to the smallest internuclear distance. So for each possible crystal structure...

of the experiments. Both materials form under conditions promoting ideal crystal growth, and may lack the Moss defects of quartz grains in granites....

phases obtained as ideal 3D photonic crystals in large volumes have been stabilized and produced with different controlled crystal lattice orientations...

In crystallography, crystal structure is a description of ordered arrangement of atoms, ions, or molecules in a crystalline material. Ordered structures...

particular AgBr) were a result of deviations from an ideal crystal structure. Factors such as crystal growth, impurities, and surface defects all affect...

Laue reflection. Topographs often reveal the irregularities in a non-ideal crystal lattice. X-ray diffraction topography is one variant of X-ray imaging...

scientist Jagadish Chandra Bose was the first to use a crystal for detecting radio waves in 1894. The crystal detector was developed into a practical device for...

single crystal. The interface between a crystal and its vapor can be molecularly sharp at temperatures well below the melting point. An ideal crystalline...

A crystal model is a teaching aid used for understanding concepts in crystallography and the morphology of crystals. Models are ideal to learn recognizing...

Crystal twinning occurs when two or more adjacent crystals of the same mineral are oriented so that they share some of the same crystal lattice points...

potential may or may not lead to a surface state in a band gap. An ideal one-dimensional crystal of finite length L = N a {\displaystyle L=Na} with two ends...
