چکیده
Based on the previous studies of RNA nanorings, in this contribution we computationally analyze the structure and properties of RNA nanotubes, where we focus on nanotubes consisting of up to five nanorings of around 20nm in diameter. We have developed a molecular dynamics (MD) method and implemented it by using the NAMD and VMD packages in a high-performance computing environment to study the structural and thermal properties of the nanotube in physiological solutions. In particular, we have analyzed such characteristics as the Root Mean Square Deviation (RMSD), the radius of gyration, the number of hydrogen bonds per base pairs, and the radial distribution function for the different nanoclusters in nanotubes of various sizes. Due to flexibility of RNA molecules, we can build various motifs which are essential in bionanotechnological applications such as scaffolding and drug delivery systems.

Use of Structure Codes (Counts) for Computing Topological Indices of Carbon Nanotubes: Sadhana (Sd) Index of Phenylenes and its Hexagonal Squeezes
Structural codes vis-a-vis structural counts, like polynomials of a molecular graph, are important in computing graph-theoretical descriptors which are commonly known as topological indices. These indices are most important for characterizing carbon nanotubes (CNTs). In this paper we have computed Sadhana index (Sd) for phenylenes and their hexagonal squeezes using structural codes (counts). Sa...

The Wiener index of a graph Gis defined as W(G) =1/2[Sum(d(i,j)] over all pair of elements of V(G), where V (G) is the set of vertices of G and d(i, j) is the distance between vertices i and j. In this paper, we give an algorithm by GAP program that can be compute the Wiener index for any graph also we compute the Wiener index of HAC5C7[p, q] and HAC5C6C7[p, q] nanotubes by this program.
