The mol-ecule of the title compound, C(32)H(34)Si(2), is situated about a centre of symmetry. The whole diphenyl-ethene fragment is planar and the C(ar)-Si-C(3) group is rotated by ca 30° with respect to the plane of the benzene ring. The crystal structure is stabilized by some C-H⋯π contacts as well as van der Waals inter-actions.

Using a combination of Z-contrast imaging and atomically resolved electron energy-loss spectroscopy on a scanning transmission electron microscope, we show that the chemical bonding of individual impurity atoms can be deduced experimentally. We find that when a Si atom is bonded with four atoms at a double-vacancy site in graphene, Si 3d orbitals contribute significantly to the bonding, resulti...

Here we explore in silico an alternative to make planar eight π-electron bare ring systems with substitutions of some cyclooctatetraene ring carbon atoms by heavier group 14 elements. We found that the most stable eight membered rings with formulae C(4)Si(4)H(8), C(4)Ge(4)H(8), and C(4)Sn(4)H(8) have a perfect planar structure, enhancing delocalization energy as compared to cot.

Multiwall carbon nanotubes (MWCNTs) are grown via chemical vapour deposition method directly on a stainless steel substrate. Raman spectroscopy and transmission electron microscopy are the techniques chosen to characterize the structure of the synthesized carbon nanotubes: few structural defects are detected. After their removal from the stainless steel substrate, the as-grown MWCNTs are then a...

A density functional theory investigation has been presented in this work on M(5)H(5)X hydrometal pentagons (M = Ag, Au, Pd, P) with D(5)(h) planar pentacoordinate nonmetal centers (X = Si, Ge, P, S). The introduction of the nonmetal centers X introduces p aromaticity to M(5)H(5)X complexes. These novel planar complexes are favored in thermodynamics and confirmed to be aromatic in nature. They ...

For the development of reliable vertical GaN transistors, a detailed analysis robustness gate stack is necessary, as function process parameters and material properties. To this aim, we report breakdown performance planar GaN-on-Si MOS capacitors. The carried out on capacitors processed different bulk doping (6E18 Si/cc, 6E17 Si/cc 2.5E18 Mg/cc, p-type), structures (planar, trench-like) geometr...

The present work is a comparative study of possible adsorption structures of the conjugated molecule acrylonitrile on Si(001) employing the state of the art pseudopotential method, within a generalized gradient approximation to the density functional theory. In the recent literature it is proposed the interaction of acrylonitrile with Si(001) through a cycloaddition reaction of the cyano group,...

In the study, the chemically-derived reduced graphene oxide flakes on the pyramidal Si substrate to construct the heterojunction solar cells via simple spin-coating process have been presented. The total reflectance of chemically-derived graphene on pyramidal Si is ~12% at the wavelength of 550 nm which is remarkably reduced compared with that of reduced graphene oxide on planar Si. By modifyin...
