Commercializing direct methanol fuel cells (DMFC) demands cost-effective cation exchange membranes. Herein, a polymeric blend is prepared from low-cost and eco-friendly polymers (i.e., iota carrageenan (IC) and polyvinyl alcohol (PVA)). Zirconium pho

In this paper we provide exact formula for the commute times of random walks on spherically symmetric random trees. Using this formula we sharpen some of the results presented in Al-Awadhi et al. to the form of equalities rather than inequalities.

The speed of the random walk on a tree is the rate of escaping its starting point. It depends on the way that the branching occurs in the sense that if the average number of branching is large, the speed is more likely to be positive. The speed on so

We study the relationship between the type of the random walk on some random trees and the structure of those trees in terms of fractal and resistance dimensions. This paper generalizes some results of Refs. 8–10.

The speed of a random walk on a graph depends on the structure of that graph. We consider the simple random walks on infinite leafless trees, where the speed is closely related to the branching rate in such a way that the more the branching of the tr

In this article we study the commute and hitting times of simple random walks on spherically symmetric random trees in which every vertex of levelnhas outdegree 1 with probability 1−qnand outdegree 2 with probabilityqn. Our argument relies on the l
