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 review on lithium recovery using electrochemical capturing systems
(
Elsevier
, 2021 , Article Review)
Resource recovery from natural reserves is appealing and Li extraction from different brines is in the forefront. Li extraction by membranes is reviewed in the literature much more than electrochemical processes. However, ...
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 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 ...
Social And Behavioral Risk Factors Influencing Driver's Involvement In Rd Traffic Accidents In Qatar
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference)
On average, traffic accidents kill around 137 people around the world every hour. In 2004, road injuries were the first leading cause of death and predicted to be the fifth leading cause of death by 2030. Although the ...
Production Of Size-selected Copper Nanoclusters For Petroleum Refinery Applications
(
Hamad bin Khalifa University Press (HBKU Press)
, 2014 , Conference)
Atomic nanoclusters exhibit large surface to volume ratio which enhances their ability to interact with external materials, thus, they can be utilized efficiently for catalysts and gas sensing applications. Copper (Cu) ...
