A study of low-temperature CO oxidation over mesoporous Cuo-TiO2 nanotube catalysts
(
MDPI AG
, 2017 , Article)
Supported copper oxide nanoparticles have attracted considerable attention as active and non-precious catalysts for many catalytic oxidation reactions. Herein, mesoporous xCuO-TiO2 nanotube catalysts were fabricated, and ...
A novel method to identify initial values of chaotic maps in cybersecurity
(
MDPI AG
, 2019 , Article)
Chaos theory has applications in several disciplines and is focusing on the behavior of dynamical systems that are highly sensitive to initial conditions. Chaotic dynamics are the impromptu behavior displayed by some ...
Hydrogen Atom and Equivalent Form of the Levy-Leblond Equation
(
Institute of Physics Publishing
, 2017 , Article)
We discuss the equivalent form of the Levy-Leblond equation such that the nilpotent matrices are two-dimensional. We show that this equation can be obtained in the non-relativistic limit of the (2+1)-dimensional Dirac ...
Two-stage complete allocation sampling
(
John Wiley and Sons Ltd
, 2017 , Article)
An adaptive sample involves modifying the sampling design on the basis of information obtained during the survey while remaining in the probability sampling framework. Complete allocation sampling is an efficient and easily ...
Confined Interfacial Monomicelle Assembly for Precisely Controlled Coating of Single-Layered Titania Mesopores
(
Cell Press
, 2019 , Article)
The development of core-shell structures has been in great demand recently owing to their integrated functionalities. However, the progress in reliable coating of porous semiconductors remains unproductive. Here, we have ...
Recycling of Date Pits Into a Green Adsorbent for Removal of Heavy Metals: A Fractional Factorial Design-Based Approach
(
Frontiers Media S.A.
, 2019 , Article)
Date pits (DPs) have been recycled into a low-cost adsorbent for removing of selected heavy metals (HMs) from artificially contaminated aqueous solutions. Adsorption of targeted HMs, both by raw date pits (RDP) and burnt ...
Production of sensitive gas sensors using CuO/SnO2 nanoparticles
(
Springer Verlag
, 2019 , Article)
Metal oxide nanoparticles, such as CuO and SnO2, are outstanding systems for H2S gas sensing in air. In this work, those nanoparticles were deposited with different mixing percentages on substrates to form percolating ...
Improved photocatalytic decomposition of methyl ethyl ketone gas from indoor air environment by using TiO2/graphene oxide
(
Institute of Physics Publishing
, 2019 , Article)
This study investigates the potential application of synthesized TiO2-graphene (Ti/GO) for the decomposition of methyl ethyl ketone (MEKT) in an indoor air environment. XRD and UV-vis studies on the materials confirmed ...
Enhancement of Ethanol Production in Electrochemical Cell by Saccharomyces cerevisiae (CDBT2) and Wickerhamomyces anomalus (CDBT7)
(
Frontiers Media S.A.
, 2019 , Article)
Bioethanol (a renewable resource), blended with gasoline, is used as liquid transportation fuel worldwide and produced from either starch or lignocellulose. Local production and use of bioethanol supports local economies, ...
A semiparametric nonlinear mixed model approach to phase I profile monitoring
(
Taylor and Francis Inc.
, 2019 , Article)
When process data follow a particular curve in quality control, profile monitoring is suitable and appropriate for assessing process stability. Previous research in profile monitoring focusing on nonlinear parametric (P) ...
