Experimental and theoretical investigation on the inhibition performance of disulfide derivatives on cobalt corrosion in alkaline medium
(2021)
Cobalt, as the barrier layer material for 14 nm copper interconnection, has been widely applied owing to its superior characteristics of low resistivity, excellent adhesion performance and blocking properties for copper. ...
Quantum chemical studies and electrochemical investigations of pyrogallol red modified carbon paste electrode fabrication for sensor application
(2021)
In order to develop a sensing platform, it is very important to understand the sensing mechanism of the modified electrode by locating the redox reactive sites of the modifier, for this better understanding we used the ...
Investigations on some coumarin based corrosion inhibitors for mild steel in aqueous acidic medium: Electrochemical, surface morphological, density functional theory and Monte Carlo simulation approach
(2021)
Two coumarin derivatives, namely, 3-(3-benzyl-4-hydroxy-2-thioxo-3,4-dihydro-2H-1,3-thiazin-6-yl)-8-methoxy-2H-chromen-2-one (BTMC) and 3-(3-benzyl-4-hydroxy-2 thioxo-3,4-dihydro-2H-1,3-thiazin-6-yl)-2H-chromen-2-one (BTC) ...
Experimental and In Silico studies on optical properties of new thiadiazole tetrasubstituted metal-free and zinc phthalocyanine compounds
(2021)
In this study, 2-amino-5-phenyl-1,3,4-thiadiazole substituted metal-free phthalocyanine (H2Pc) was synthesized by tetramerization reaction of the phthalonitrile derivative. The synthesized compound was characterized by IR, ...
Optical properties of a GaAs quantum well with new type of hyperbolic confinement potential: Effect of structure parameters and intense laser field
(Optics Communications, 1July 2021)
In this present study, we have investigated theoretically the effect of structure parameters (η and κ) and
high-frequency intense laser field (ILF) on the linear and nonlinear optical properties of a GaAs quantum well
(QW) ...
Application of levulinic acid-based natural deep eutectic solvents for extraction and determination of deltamethrin in food samples
(13 October)
In the study, a fast and green natural deep eutectic solvent based ultrasound-assisted liquid liquid
microextraction (NDES-UALLME) were proposed for the determination and extraction of
deltamethrin in food samples using ...
Bandgap engineering, monolithic growth, and operation parameters of GaSb-based SESAMs in the 2–2.4 μm range
(Optical Materials Express, 2022/6/1)
We present the detailed growth and characterization of novel GaSb-based semiconductor saturable absorber mirrors (SESAMs) operating in the 2–2.4 µm spectral range. These SESAMs at different wavelengths are bandgap engineered ...
High-power low-noise 2-GHz femtosecond laser oscillator at 2.4 μm
(Optics Express, 2022/2/14)
Femtosecond lasers with high repetition rates are attractive for spectroscopic applications with high sampling rates, high power per comb line, and resolvable lines. However, at
long wavelengths beyond 2 µm, current laser ...
Linear and nonlinear optical properties of semi-elliptical InAs quantum dots: Effects of wetting layer thickness and electric field
(Thin Solid Films, 2022/8/1)
In this paper, we have studied the optical properties of semi-elliptical InAs quantum dots (QDs) embedded in GaAs. Under effective mass approximation, the finite element method has been used to obtain wavefunctions and ...
Vortex assisted magnetic ionic liquid based dispersive liquid–liquid microextraction approach for determination of metribuzin in some plant samples with UV–Vis spectrophotometer
(26 July 20)
A vortex assisted magnetic ionic liquid based dispersive liquid–liquid microextraction (VA-MIL-DLLME)
approach was proposed using a tetrachloromanganate-based magnetic ionic liquid (MIL, as extraction solvent) for the ...
