    Abstract: Diatomic model, when is utilized to describe clusters of identical atoms, takes into account bonding only between neighboring pairs of atoms. According to the diatomic model, isomers of wrapped forms, e.g. built from nanotubular and/or fullerene-like structural fragments, have to be more stable energetically than their planar counterparts because p...

    Abstract: Today, nano-sized capacitors are widely used for storage of electric energy. Consequently, it’s too important the knowing how to estimate their capacitance theoretically. This can’t be done based on the standard formula useful for macroscopic capacitors with bulk dielectric layers. There is proposed a new formula determining nanocapacitance from ef... Show More
