چکیده

A straightforward strategy has been used to construct large BN-embedded π-systems simply from azaacenes. BN heterosuperbenzene derivatives, the largest BN heteroaromatics to date, have been synthesized in three steps. The molecules exhibit curved π-surfaces, showing two different conformations which are self-organized into a sandwich structure and further packed into a π-stacking column. The assembled microribbons exhibit good charge transport properties and photoconductivity, representing an important step toward the optoelectronic applications of BN-embedded aromatics.

Carbon and BN nanocones as nano carriers for 5-Fluorouracil, a DFT study

5-Fluorouracil (5-FU) is an anticancer drug. In this work, we have investigated the electronic properties and topological analysis of interaction between 5-FU and carbon nanocone and BN nanocone. The structural stability of isomer complexes of 5-FU with carbon nanocone and BN nanocone have been investigated for two position of interactions. We have found that the most stable complexes are forme...

Load-Frequency Control: a GA based Bayesian Networks Multi-agent System

Bayesian Networks (BN) provides a robust probabilistic method of reasoning under uncertainty. They have been successfully applied in a variety of real-world tasks but they have received little attention in the area of load-frequency control (LFC). In practice, LFC systems use proportional-integral controllers. However since these controllers are designed using a linear model, the nonlinearities...

Structure and electronic properties of single–walled zigzag BN and B3C2N3 nanotubes using first-principles methods

The structure and the electronic properties of single-walled zigzag BN and B3C2N3 nanotubes (n, 0; n=4–10) were investigated using first-principles calculations based on a density functional theory. A plane–wave basis set with periodic boundary conditions in conjunction with Vanderbilt ultrasoft pseudo-potential was employed. The energy gap of ZB3C<su...
