It can be reasonably assumed that the enlarged space across the APB-I weakens the bonding strength of the Fe-O polyhedral sites, leading to the extra oxygen vacancies36,37,38,39. The EELS map in an enlarged view of APB-I (Supplementary Fig. 5a) further reveals that the oxygen ...

6. Each point in this figure represents a refined crystal structure, and the distance between points indicates their similarity. The majority of the refined structures form a loose cluster at the lower-right side of the figure, which means they are similar to each other. In the cluster, ...
Nevertheless, these observations provide an explanation of the promiscuity that one NSF can disassemble many different species of SNARE complex along with just a few SNAP homologues in vivo: electrostatic interactions are not as specific as hydrogen bonding interactions and only require conserved ...
Embedded cluster calculations at the MP2 electron correlation level of pure and Zn- and Ni-doped YBa 2 Cu 3 O 7 (Y123) ceramics reveal great changes of the local charge distribution and crystal bonding in the vicinity of impurities. In t... I Kaplan,J Soullard,J Hérnandez-Cobos - 《...
However, an isolated regular boron icosahedron is an electron-deficient structure—the total number of valence electrons of 12 boron atoms is not sufficient to fill all the covalent bonding orbitals corresponding to such a cage-molecule. Thus, if it were a stable structure, then intra-icosahedral...
On the other hand, there seemed to be insufficient bonding between the particles and the virgin matrix. GTR particles were present as a dispersed phase consisting of large grains with poor compatibility and weak interactions with the SBR, as can be observed in SEM micrographs (Figure 6b) [13]...
For examples, DFMAC uses an orientation-dependent potential term between two Cα-pseudo-Cβ vectors [21], and in OPUS-Cα, the distance-dependent pairwise energy term and hydrogen bonding energy term are also orientation-dependent [23]. These orientation-dependent potentials are sensitive to ...
