在每个理论中,其它原素原子的化学性质,都与从最近的单原子气体的电子构型得失电子,紧密相连。
In each theory, the chemical properties of atoms of other elements were tied to the gain or loss of electrons from the configuration of the nearest monatomic gas.
这些理论如此成功地解释了元素很广泛的化学性质,以致于,人们逐渐认为:在化学上,“单原子气体电子构型”不可违背。
So successful were these theories in accounting for a wide range of chemical properties of the elements that the monatomic-gas electron configurations came to be thought of as chemically inviolate.
但是美国化学学会期刊Nano上面刊登的一份文章显示,少量的碳单原子层可以解决这个问题。
But a paper just published in the American Chemical Society's journal, Nano, by Dr Corral and her colleagues, suggests a sprinkling of graphene may deal with that.
可操作反应器来以单原子层精度以及高速化学气相处理模式处理多个挠性或扁平衬底。
The reactor can be operated to process multiple flexible or flat substrates with a single atomic layer precision as well as high-speed chemical vapor processing mode.
单原子的结构是个基本极限:若要做得更小,基本上就得操控原子核了,这可是把一种化学元素转换为另一种。
A structure the size of an atom represents a fundamental limit: to make anything smaller would require manipulating atomic nuclei—essentially, transmuting one chemical element into another.
