These developments include exotic buildings with programmable lattice symmetries and properly-outlined crystal behaviors, responsive products that leverage the intrinsic Qualities of nucleic acids to govern constructions on need, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals which offer insights into light-weight–make any difference interactions. Wanting ahead, we challenge the Neighborhood to leverage the amazing structural control afforded by crystal engineering with DNA to synthesize classes of practical materials that thrust beyond what is probable with The natural way occurring crystalline components or Individuals made by far more common methods.
Tetragonal: These crystals variety prisms and double pyramids. The framework is like a cubic crystal, apart from a single axis is for a longer period than the opposite.
Crystalline framework is characterized by a geometrical, repeating pattern of symmetric molecular composition. The arrangement of atoms types these ordered, repeating styles.
, has the exact same framework, but There are 2 decisions for choosing the holes which the atoms will occupy. The third layer may be put above the atoms of the main layer, producing an alternate layer sequence A
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。
Crystals may be grown beneath average circumstances from all 92 naturally transpiring factors apart from helium, and helium can be crystallized at reduced temperatures by utilizing 25 atmospheres of tension.
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。
Crystals with evident flat faces are referred to as euhedral crystals, when All those lacking defined faces are termed anhedral crystals. Crystals consisting of ordered arrays of atoms that aren't generally periodic are identified as quasicrystals.

水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
A different type of crystalline carbon relies Crystal with a molecule with sixty carbon atoms known as buckminsterfullerene (C60). The molecular condition is spherical. Just about every carbon is bonded to a few neighbours, as in graphite, as well as spherical condition is obtained by a mixture of 12 rings with 5 sides and twenty rings with 6 sides. Identical structures were very first visualized through the American architect R. Buckminster Fuller for geodesic domes.
