Pt-Based Nanostructures for Electrochemical Oxidation of CO: Unveiling the Effect of Shapes and Electrolytes
(
MDPI
, 2022 , Article)
Direct alcohol fuel cells are deemed as green and sustainable energy resources; however, CO-poisoning of Pt-based catalysts is a critical barrier to their commercialization. Thus, investigation of the electrochemical CO ...
A Note on a Class of Generalized Parabolic Marcinkiewicz Integrals along Surfaces of Revolution
(
MDPI
, 2022 , Article)
In this article, certain sharp Lp estimates for a specific class of generalized Marcinkiewicz
operators with mixed homogeneity associated to surfaces of revolution are established. By virtue of
Yano’s extrapolation ...
Duration of immune protection of SARS-CoV-2 natural infection against reinfection.
(
Oxford University Press
, 2022 , Article)
The future of the SARS-CoV-2 pandemic hinges on virus evolution and duration of immune protection of natural infection against reinfection. We investigated duration of protection afforded by natural infection, the effect ...
Covid-19 Vaccine Protection among Children and Adolescents in Qatar.
(
Massachusetts Medical Society
, 2022 , Article)
The BNT162b2 vaccine against coronavirus disease 2019 (Covid-19) has been authorized for use in children 5 to 11 years of age and adolescents 12 to 17 years of age but in different antigen doses. We assessed the real-world ...
Rectangular eigenvalue problems
(
Springer
, 2022 , Article)
Often the easiest way to discretize an ordinary or partial differential equation is by a rectangular numerical method, in which n basis functions are sampled at m ≫ n collocation points. We show how eigenvalue problems can ...
Numerical investigation of a novel solar cell based on a modified perovskite with PPP polymer
(
Elsevier
, 2022 , Article)
In this paper, a new, highly efficient and eco-friendly solar cell device based on a modified perovskite material from CsMAFA, with a polymer as an absorber layer, is modelled and simulated by utilizing the SCAPS-1D. An ...
The relevance of supply side taxation for attracting foreign direct investment to developing countries: evidence from Egypt
(
University of New South Wales
, 2021 , Article)
Many developing countries commonly use tax incentives as a key instrument for attracting foreign direct investment (FDI). Empirical studies have identified a causal relationship between FDI and a number of determinants ...
The general solution for the relativistic and nonrelativistic Schrödinger equation for the δ(n) -function potential in 1-dimension using cutoff regularization, and the fate of universality
(
World Scientific Publishing
, 2022 , Article)
A general method has been developed to solve the Schrödinger equation for an arbitrary derivative of the δ-function potential in 1-d using cutoff regularization. The work treats both the relativistic and nonrelativistic ...
Simulation of natural convective heat transfer and entropy generation of nanoparticles around two spheres in horizontal arrangement
(
Elsevier
, 2021 , Article)
Herein, laminar convective heat transfer from two horizontally arranged spheres has been evaluated by using numerical models inside water-based fluids incorporated with alumina (Al2O3), copper oxide (CuO), and copper (Cu) ...
Numerical Simulation of Magnetic Dipole Flow Over a Stretching Sheet in the Presence of Non-Uniform Heat Source/Sink
(
Frontiers Media
, 2021 , Article)
The main objective of current communication is to present a mathematical model and numerical simulation for momentum and heat transference characteristics of Maxwell nanofluid flow over a stretching sheet. Further, magnetic ...
