Thermoelectric properties of SbNCa3 and BiNCa3 for thermoelectric devices and alternative energy applications
(
Elsevier B.V.
, 2014 , Article)
Thermoelectric properties of two antiperovskites SbNCa3 and BiNCa3 are calculated using first principles calculations. High values of Seebeck coefficients are observed for these materials. Electrical and thermal conductivities ...
Edge-Maximal Graphs Without θ2k+1-Graphs
(
Taylor and Francis Ltd.
, 2014 , Article)
Let σ(n; θ2k+1) denote the class of non-bipartite graphs on n vertices having no θ2k+1- graph and f(n; θ2k+1) = max{ ε(G): G ∊ σ (n; θ2k+1)}. In this paper we determine f(n; θ2k+1), by proving that for k ≥ 4 and n ≥ 36k. ...
Edge-Maximal θ2k+1-Edge Disjoint Free Graphs
(
Kyungmoon Publishing
, 2014 , Article)
For two positive integers r and s, G(n; r; θs) denotes to the class of graphs
on n vertices containing no r of edge disjoint θs-graphs and f(n; r; θs) = max{E(G) :
G ∈ G(n; r; θs)}. In this paper, for integers r, k ≥ 2, ...
The ramsey number for theta graph versus a clique of order three and four
(
University of Zielona Gora
, 2014 , Article)
For any two graphs F1 and F2, the graph Ramsey number r(F1, F2) is
the smallest positive integer N with the property that every graph on at
least N vertices contains F1 or its complement contains F2 as a subgraph.

Electronic vs Ionic limitations to electrochemical performance in Li4Ti5O12-based organic suspensions for lithium-redox flow batteries
(
Electrochemical Society Inc.
, 2014 , Article)
Here, we report the electrochemical response of the LTO/KB anolytes vs. lithium as function of the cycling rate in static mode (i.e. no flow) and using a home-made cell. The KB content was fixed at 3 wt% while the LTO ...
