亞納米的定義是什么？ 已有3人參與
|
|||
 向大家請教一個(gè)問題，我想知道“亞納米”的具體定義是什么？到底是定義為三個(gè)維度中有一個(gè)維度在1 nm以下或接近1 nm可以被稱為亞納米，還是只要三個(gè)維度中有一個(gè)維度低于10 nm都可以稱為亞納米？最好能提供相關(guān)的文獻(xiàn)。感謝大家�。� |

The word “sub-nanometer” is increasingly used recently. However, the size strictly confined within 1 nm is difficult to determine, since there might be errors in most of the size conventional characterization tools, and the featured size might not be even in the overall structures, especially at this extremely small scale. Moreover, whether there is or should be a critical size level to differentiate sub-nanometric material （SNMs） from conventional nanomaterials is not clear, in spite of the fact that it is well-accepted that the size of nanomaterials would certainly influence their properties. The size scale of sub-nanometer bridges the molecular level and the conventional nanoscale, and an increasing number of novel properties are being progressively researched. Specially specifying this size scale might help to attract wide interest on this special topic. We consider the materials as the so-called SNMs when two aspects are met: 1) the size of materials are confined at the level of a single-unit cell of crystals or molecular level; 2) some unique (size-related) properties comparing to nanomaterials at large sizes can be obtained. ——Ni Bing,Shi Yuang,Wang Xun,The Sub-Nanometer Scale as a New Focus in Nanoscience.[J] .Adv.

納米材料：至少有一維處于納米尺度范圍（0.1～100n）或由它們作為基本單元構(gòu)成的材料。有一維就可以了。 https://wenku.baidu.com/view/79adfabb960590c69ec37683.html 亞納米的意思是材料尺寸大一些，有一維快達(dá)到100納米了。比如200納米或500納米。都叫亞納米 |
