چکیده

Capillary electrophoretic methods are traditionally used for the separation of charged species. A neutral compound is often used as a background (electroosmotic flow) marker. The assumption made is that no significant interaction occurs between neutral compounds and the various ions moving through the capillary. This is true for aqueous environments because the very polar nature of water overpowers any interactions that might occur. However, in a non-aqueous solvent such as methanol some interaction might occur between a neutral compound and ions in solution. This analysis was performed to determine the extent of these interactions between neutral species and ions, if any. These interactions, if significant, indicate that capillary electrophoresis could also be used for the separation of neutral species.

COMPUTING WIENER INDEX OF HAC5C7[p, q] NANOTUBES BY GAP PROGRAM

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.
