Elucidating the mechanism for the chemical vapor deposition growth of vertical MoO2/MoS2 flakes toward photoelectrochemical applications
(
Elsevier B.V.
, 2020 , Article)
To control the growth of layered two-dimensional transition metal dichalcogenide (TMD) materials or complex structures such as heterostructures, it is important to understand the growth mechanism. In this study, we ...
Electrospun nanofibers of PVDF-HFP composites containing magnetic nickel ferrite for energy harvesting application
(
Elsevier Ltd
, 2020 , Article)
Nickel ferrite nanoparticles (NiFe2O4) synthesized by chemical co-precipitation method, are added to poly(vinylidene fluoride-co-hexafluoroproplyene) (PVDF-HFP) in specific concentrations (1, 2, and 3 wt%) and the composite ...
α-Fe2O3/ZnO nanocomposite as an efficient photocatalyst for wastewater treatment and flexible electronic device applications
(
Springer
, 2024 , Article)
In this work, we report the synthesis of α-Fe2O3, ZnO, and α-Fe2O3/ZnO nanomaterials by a simple sol-gel method for photocatalytic dye degradation and flexible electronic applications. X-ray diffraction results reveal that ...
Fundamental group and cycle space of dual graphs and applications
(
Elsevier
, 2010 , Article)
In this work, we study the fundamental group of dual graph of a planar graph. Moreover, we show that a planar graph G has no cut vertex if and only if N(Π(D(G))) = N(Π(D(G − v))) − 1 for any v ∈ V(G). Some applications ...
On the basis number of the wreath product of paths with wheels and some related problems
(
Charles Babbage Research Centre
, 2017 , Article)
In this paper, we investigate the basis number for the wreath product of wheels with paths. Also, as a related problem, we construct a minimum cycle basis of the same.
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. ...
Melt processing and properties of linear low density polyethylene-graphene nanoplatelet composites
(
Elsevier Ltd
, 2016 , Article)
Composites of Linear Low Density Polyethylene (LLDPE) and Graphene Nanoplatelets (GNPs) were processed using a twin screw extruder under different extrusion conditions. The effects of screw speed, feeder speed and GNP ...
A new upper bound of the basis number of the lexicographic product of graphs
(
Charles Babbage Research Centre
, 2010 , Article)
An upper bound of the basis number of the lexicographic product of two graphs from the basis number of the factors is presented. Furthermore, the basis numbers of the lexicographic product of some classes of graphs is determined.
Minimum cycle bases for direct products of K2 with complete graphs
(
University of Queensland Press
, 2009 , Article)
We construct a minimum cycle basis for the direct product K2 x Kp of two complete graphs where p > 2. For p > 3, these bases consists only of squares. This completes the work of R. Hammack, who treated the case Kp x ...
Correlating the rheological and magneto-optical properties of cobalt substituted magnetite ferrofluids (CoxFe1?xFe2O4) with theoretical studies
(
Elsevier B.V.
, 2023 , Article)
Magnetite ferrofluids are widely reported due to their outstanding physicochemical, magnetic and antibacterial properties. This study focusses on the synthesis of magnetite ferrofluids and the effect of Co2+ substitution ...
