This idea applies equally in a single, two, and three-dimensional spaces. The entire crystal lattice can be manufactured by repeatedly reproducing the pattern in the unit mobile in all Instructions.
12He tried all over again in quite a few other metropolitan areas and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
These improvements involve unique constructions with programmable lattice symmetries and well-defined crystal patterns, responsive resources that leverage the intrinsic Qualities of nucleic acids to govern structures on desire, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals that supply insights into gentle–make any difference interactions. On the lookout forward, we obstacle the Local community to leverage the amazing structural Management afforded by crystal engineering with DNA to synthesize lessons of useful elements that thrust further than what has been possible with Normally happening crystalline elements or Those people made by far more typical tactics.
Significant crystals of diamond are worthwhile gemstones. The crystal has other appealing Qualities; it's got the best sound velocity of any solid and is the greatest conductor of heat. In addition to diamond, another frequent sort of carbon is graphite, and that is a layered material. Each carbon atom has a few coplanar in the vicinity of neighbours, forming an arrangement known as the honeycomb lattice. 3-dimensional graphite crystals are acquired by stacking identical levels.

From your Cambridge English Corpus We are saying the chain topology in the superior w area functions since the proverbial ' scratch-on-theglass ' wanted from the natural and organic chemistry laboratory to create crystals. In the Cambridge English Corpus Frequent-stress and temperature molecular-dynamics simulations of crystals of your lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Through the Cambridge English Corpus Besides these, dust particles happen to be observed in lower-temperature plasmas, like Individuals used in plasma processing and plasma crystals. With the Cambridge English Corpus The final Component of the e-book focuses on peculiarities of strongly coupled dusty plasmas, including the development of dust crystals and involved attractive forces. From the Cambridge English Corpus Complete characterization of injury threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, Most important morphologies weren't observed. Through the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from sources on the web. Any opinions from the illustrations tend not to symbolize the impression in the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
You will discover other minerals and molecules which can kind these crystal lattices. Snowflakes are a traditional example more info of a roughly symmetric and geometrically patterned framework from ice crystals, and gemstones of all versions are generally crystals.
玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
