Sentence examples for planar clusters from inspiring English sources

Now we turn to aromaticity which, as already mentioned, is considered as the basis of stability for boron planar clusters.

The quasi-planar or fully planar clusters, for a change, will be often labeled as 2D structures.

The occurrence of nanostructured planar clusters is shown to be caused by the presence of excess manganese.

It has been suggested that the anomalous stability of the boron planar clusters depends on the aromaticity which arises from the delocalization of π-electrons and involves unoccupied 2p z atomic orbitals [11, 12, 14].

To examine the influence of charge on the structure and stability of the fully planar clusters, we have also studied charged 2D and 3D B12X6 (X = H, F) structures.

The atoms within the layer are likely 5- and/or 6- rather than 4-coordinated in view of the structure of planar clusters of Au [26] and the fact that gold (100) film reconstructs into a (111) film below ca. 8 atomic layers, whereas the (111) film can be thinned further layer by layer [27].

Encouraged by fellow physicists Freeman Dyson and Richard Feynman, he posited a "planar cluster" housing four billion people across 30,000km of space.

Additionally, Piazza et al.'s [14] study provide experimental evidence that the monolayer boron sheets are achievable based on their observations of B36 cluster; it was shown to be a highly stable planar cluster with a central hexagonal hole [14].

We have extensively used this approach in our earlier calculations on conjugated polymers [24 27] as well as on B12 icosahedral and quasi-planar clusters reported recently [28].

As can be seen from the figure, the quasi-planar clusters with up to four hydrogen atoms are more stable than the corresponding icosahedral structures (a similar result has been recently reported [11] for B12H n 0/- clusters).

In another theory--experiment study, Zhai et al. [8] reported the discovery of planar boron clusters B8 and B9 clusters with "molecular wheel -like structures and exhibiting both σ and π aromaticity.
