解析 首先句子后面是作定语的,由主句可以知道,修饰的是主语element.因为atoms是原子的意思,对于元素来说,逻辑关系自然是“元素里的原子”,所以element和atoms具有从属关系,用whose(注意啦!在定语从句表示从属关系的时候,关系词whose不仅仅适用于人,也可以适用于物) ...
Also, the nanocrystalline oxide layer has fast self-healing properties so that it can re-form instantaneously when damaged, thus maintaining the alloy’s corrosion protection47,48,49,50,51. The STEM and EDS analysis on the oxide in Supplementary Fig. 11 shows that the Zn-rich area beneath ...
First is the Hartree potential V_{\rm{H}}, another is the exchange-correlation potential V_{\rm{XC}}. 2.2. Hartree potential The Hartree potential is defined as: \begin{aligned} V_{\rm{H}}(\boldsymbol{r}) & = \int {\rm{d}}\boldsymbol{r}' \, \frac{n(\boldsymbol{r}')}{...
The nearly spherical fullerene molecules have high structural and chemical stability. For example, due to their large electron affinity, these molecules can form various derivative synthetic systems, such as hetero, endohedral fullerenes that encapsulate a single ion, atom, or even small molecules such...
Using calculated valence charge densities, we show that the valence electrons of the K atoms are almost completely transferred to the lowest unoccupied bands of the ${mathrm{C}}_{60}$ molecular solid... JL Martins,N Troullier - 《Physical Review B》 被引量: 210发表: 1992年 DENSITIES OF ...

In Python, iterating over the atoms in a Mol is 10-20x slower than it needs to be. It's ROMol is much slower than iterating over the atom indices and getting each one! I'm using a pre-beta version of the 2023 spring release candidate, bu...
Economical with the atoms
traditional magnets, large spins arise from the Hund’s coupling, and the spins of the localized electrons on the same lattice site are aligned to form a large spin. The leading order contribution to the couplings between different sites is the Anderson’s superexchange of a single pair of ...
