8Where will 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？
Bismuth (Bi) seems to become a steel, but the quantity of electrons available for electrical conduction is analogous to that of semiconductors. In truth, bismuth is called a semimetal. Molecular solids tend to be crystals shaped from molecules or polymers. They are often insulating, semiconducting, or metallic, dependant upon the style of molecules during the crystal. New molecules are repeatedly remaining synthesized, and many are created into crystals. The number of unique crystals is gigantic.
These advances involve exotic constructions with programmable lattice symmetries and perfectly-described crystal behaviors, responsive supplies that leverage the intrinsic properties of nucleic acids to govern constructions on demand from customers, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals which offer insights into light-weight–matter interactions. Looking ahead, we obstacle the Neighborhood to leverage the remarkable structural Command afforded by crystal engineering with DNA to synthesize classes of purposeful elements that thrust outside of what continues to be doable with naturally developing crystalline supplies or those produced by more standard strategies.
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
Fig. 4: Creating blocks with various styles and surface chemistries immediate the formation of distinct crystal symmetries.
Encyclopaedia Britannica's editors oversee topic parts by which they may have extensive information, no matter if from yrs of experience received by focusing on that written content or by way of examine for a complicated diploma. They create new content and validate and edit information obtained from contributors.
Springer Nature continues to be neutral with regard to jurisdictional promises in revealed maps and institutional affiliations.
The elements are uncovered in a number of crystal packing preparations. The commonest lattice constructions for metals are Individuals acquired by stacking the atomic spheres into by far the most compact arrangement.
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。
say cheese something that somebody that is having a photograph of you lets you know to mention so that the mouth tends to make The form of a smile
16I opened the box and saw a piece of crystal snowflake plus a greeting card with "Satisfied Birthday" inside the blank paper.我打开盒子并看见在白纸中有一片水晶雪花和一张写着“生日快乐”的贺卡。
水晶形成后由于外力作用或某种人为原因使水晶产生大的裂隙或裂纹，这种裂纹有大有小，对水晶的影响也有大小之分。
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。
