The density functional theory has been used to optimize the geometry and study the optical absorbance (molar extinction) spectra of molecular clusters based on C32H24 and C32H36 diamondene–graphene hybrid fragments with dangling bonds compensated b

We propose the idea of a heterostructure comprising a hybrid of diamondene and graphene and describe the principle of constructing these hybrids based on observed astrophysical data. A model is constructed, its geometry is optimized, and the stabilit

Calculation results of the electronic spectrum of carbon nanospiroid C300 are presented. The π-electron structure of the spiroid is calculated using the strong coupling method, in which the matrix element of the exchange interaction of neighboring e

We describe a model of a stable, metal-modified heteromolecule based on a hybrid of diamondene and graphene containing hydrogen atoms for the stabilization of sp3 bonds. Hydrogen atoms were replaced by atoms of carbide-forming metals (Fe, Co, Ni). Af

This paper demonstrates that a free electron gas model accurately simulates the spectral dependence of optical extinction spectra for carbon spiroids under the assumption that free electrons are confined in an homogeneous spherical particle owing to

The dependence between the variation of microwave losses by a−C : H(Co) films measured at 10 GHz and alteration of Co content in the film was investigated. It was shown that microwave losses attain maximal value at approximately 33at.% of cobalt. T
