PbS/CdS heterojunction quantum dot solar cells
(
Springer New York LLC
, 2016 , Article)
The present work investigates the effects of combination of lead sulfide PbS quantum dots and cadmium sulfide CdS nanoparticles (NPs), with n-type and p-type semiconductors, on the photovoltaic performance of heterojunction ...
Standard numerical schemes for coupled parallel flow over porous layers
(
Elsevier
, 2007 , Article)
In this work, we develop finite difference schemes of various orders of accuracy that are suitable for the simulation of flow through and over porous layers. The flow through the porous layer is assumed to be governed by ...
Strange non-dissipative and non-chaotic attractors and Palmer’s deterministic quantum mechanics
(
Elsevier Ltd
, 2008 , Article)
Analytical approach to the Darcy–Lapwood–Brinkman equation
(
Elsevier
, 2007 , Article)
Three exact solutions are obtained for flow through porous media, as governed by the Darcy–Lapwood–Brinkman model, for a given vorticity distribution. The resulting flow fields are identified as reversing flows; stagnation ...
Investigation of Proton Diffusion Coefficient for PbO2 Prepared from Intermediate Oxides
(
Pleiades Publishing
, 2019 , Article)
Lead dioxide was extracted from used batteries, and used to synthesize the following intermediate oxides by heating at different temperatures: Pb12O19, Pb12O17, and Pb3O4. Each of the prepared intermediate oxide was subject ...
Positron annihilation study on polyaniline nanocomposite used for Pb(II) ion removal
(
Taylor & Francis
, 2016 , Article)
Nanocomposites of polyaniline (PANI) with three different concentrations of micrometre-sized sawdust are prepared in aqueous media via chemical casting method at room temperature. Thereafter, the removal efficiency of the ...
Effective action study of the PT-symmetric (iϕ3)6−ϵ theory and the Yang–Lee edge singularity
(
World Scientific Publishing Co. Pte Ltd
, 2019 , Article)
We use the effective potential method to study the PT-symmetric iϕ3 field theory in 6−ϵ space–time dimensions. For ϵ=0, we obtained the first two energy levels which are real as well as reflecting the stability of the ...
Solving systems of fractional differential equations using differential transform method
(
Elsevier B.V.
, 2007 , Article)
This paper presents approximate analytical solutions for systems of fractional differential equations using the differential transform method. The fractional derivatives are described in the Caputo sense. The application ...
Simpler is also better in approximating fixed points
(
Elsevier
, 2008 , Article)
In this paper we demonstrate that a number of fixed point iteration problems can be solved using a modified Krasnoselskij iteration process, which is much simpler to use than the other iteration schemes that have been defined
On the nonexistence of degenerate phase-shift multibreathers in Klein–Gordon models with interactions beyond nearest neighbors
(
Elsevier B.V.
, 2019 , Article)
In this work, we study the existence of, low amplitude, phase-shift multibreathers for small values of the linear coupling in Klein–Gordon chains with interactions beyond the classical nearest-neighbor (NN) ones. In the ...
