The nonlinear optical rectification, second and third harmonic generation coefficients of Konwent potential quantum wells
(Springer, 2022)
We have theoretically investigated the effect of structure parameters and applied external fields on the Ga1−xAlxAs/GaAs
Konwent quantum well structure. Results of theoretical simulation have clarified the impact of applied ...
Effective biosorption of Allura red dye from aqueous solutions by the dried-lichen (Pseudoevernia furfuracea) biomass
(International Journal of Environmental Analytical Chemistry, 2022)
Allura red (AR), which is known as the monoazo class of synthetic food colourant(E129) has been widely used in food industries. Due to the potential toxicity of azo dyes and pathogenicity, the removal of AR from industrial ...
Equilibrium, kinetics and thermodynamics of Pb (II) ions from aqueous solution by adsorption onto chitosan-dolomite composite beads
(International Journal of Environmental Analytical Chemistry, 2022)
This paper aims to investigate the adsorption process of a new composite adsorbent prepared from chitosan (Ch) and dolomite (Do) for removal of lead ions from aqueous solutions. The adsorp-tion process of Pb2+ions onto ...
Effects of applied external fields on the nonlinear optical rectification, second, and third-harmonic generation in an asymmetrical semi exponential quantum well
(Springer, 2022)
The asymmetric potential profiles are focus of interest for researchers who study semiconductor
optoelectronic devices. Therefore, in this study, the effects of structure parameters
(σ and V0)
and applied external ...
Nonlinear optical properties in AlxGa1-xAs/GaAs double-graded quantum wells: The effect of the structure parameter, static electric, and magnetic field
(Elsevier, 2022)
We present a theoretical simulation of the impact of applied external electric and magnetic fields, as well as of
the change in structure parameters, on the nonlinear optical rectification (NOR), second harmonic ...
Interband transitions and exciton binding energy in a Razavy quantum well: effects of external fields and Razavy potential parameters
(Springer, 2022)
In this paper, we theoretically investigated the influence of externally applied fields such as high-frequency non-resonant
intense laser fields, static electric and magnetic fields, as well as structure parameters, on ...
Investigation of optical and structural properties of tin-doped copper oxide thin films prepared by the drop-cast method
(Springer, 2022)
Tin-doped copper oxide (Sn:CuO) thin films produced by using the sol–gel drop-cast technique were examined and the effect
of Sn doping concentration on the optical properties and the energy band gap of Sn:CuO thin films ...
High-performance material for the effective removal of uranyl ion from solution: computationally supported experimental studies
(Langmuir, 2022)
Adsorption is a widely used method for pollution
removal and for the recovery of valuable species. In recent years, the
use of metal−organic compounds among the adsorbents used in
adsorption studies has increased. In ...
Synthesis and characterization of chitosan-vermiculite-lignin ternary composite as an adsorbent for effective removal of uranyl ions from aqueous solution: Experimental and theoretical analyses
(International Journal of Biological Macromolecules, 2022)
Chitosan (Ch), vermiculite (V) and lignin (L) were used as the components of a natural composite adsorbent (Ch-VL) for the removal of the UO22+ ions in aqueous solutions. During the study, we recorded and analyzed the ...
Bioremoval of Safranin O dye by the identified lichen species called Evernia prunastri biomass; biosorption optimization, isotherms, kinetics, and thermodynamics
(Biomass Conversion and Biorefinery, 2022)
Evernia prunastri (lichen), a novel, eco-friendly, cost-effective, wide availability, safe, renewable and easy collection biosorbent, has been utilized for the removal of Safranin O (SO) dye from an aqueous solution. The ...
