8Where can we get this magic wand and crystal ball?我们到哪里获得这种魔棒和水晶玻璃球？
A basic strategy in crystal structures may be the device cell. It's the smallest unit of quantity that enables similar cells being organized jointly to occupy all readily available Room. The geometrical foundation of all crystals may be the lattice. A lattice could be seen as a daily and infinite arrangement of points or atoms, in which Each and every position or atom has An analogous surrounding ecosystem.
10This will be the silicon chip—a bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
Encyclopaedia Britannica's editors oversee issue places by which they have substantial information, whether from a long time of working experience received by focusing on that content material or through review for a sophisticated degree. They compose new content material and validate and edit written content been given from contributors.
. These four structures comprise many of the binary crystals with equal numbers of cations and anions.
Lattices may have just one lattice stage for each cell or more than one, yielding a total of fourteen Bravais crystal lattice types. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the three-dimensional array created by a set of discrete factors.
Crystals search distinctive from all kinds of other rocks and minerals, but �?barring several Distinctive cases �?almost all minerals disguise a crystalline structure underneath the surface.
As a warm Option cools or even a saturated Answer evaporates, particles attract close adequate for chemical bonds to variety. Crystals could also kind from deposition straight from the gasoline period. Liquid crystals have particles oriented in an structured fashion, like reliable crystals, however have the ability to circulation.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。

正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（expansion strains）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
This Critique chronicles above two decades of exploration into creating a genetic code for crystal engineering. In lieu of directing biological processes, this code website employs artificial varieties of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each facet of the resultant constructions could be systematically controlled. Inside of this conceptual framework, the structural and practical improvements are explained in order to determine the existing volume of sophistication and to predict potential directions from the platform.
crystal Alteration is variable: absent in several crystals, in others manufacturing dense sericite aggregates which can show some recrystallization outcomes to create coarser-grained white mica. With the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes arranged in aggregates. From the Cambridge English Corpus Also, haloarchaeal cells had been embedded within salt crystals beneath laboratory ailments and subsequently analysed by mild microscopy. From the Cambridge English Corpus The white clouds (ordinarily sparse) ended up also extensively thought to be becoming made up of small crystals of drinking water ice, somewhat like cirrus in our ambiance. In the Cambridge English Corpus They're present in evaporite salt lakes and can be trapped in salt crystals all through evaporation. With the Cambridge English Corpus For that reason, the cells (organelles and membranes) are wrecked mechanically by ice crystals, leading to Loss of life as a result of cell lysis. Within the Cambridge English Corpus The crystals had been Utilized in the first or next orders of reflection. From the Cambridge English Corpus Within our 8xperiments, the crystals ended up cubes using a foundation area of 8 e mm. Through the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : influence of temperature and force.
