Effect of Chemical Composition of Boriding Agent on the Optimization of Surface Hardness and Layer Thickness on AISI 8620 Steel by Solid and Liquid Boriding Processes
(08.10.2022)
Surfaces of cam shafts made of AISI 8620 steels were hardened by boriding processes in both solid and liquid mediums. Various chemical agents were used to achieve boride layers on the surfaces of the cam shafts in these ...
Vortex assisted magnetic ionic liquid based dispersive liquid–liquid microextraction approach for determination of metribuzin in some plant samples with UV–Vis spectrophotometer
(2022)
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 ...
Application of central composite design in parameters optimization of nano-structured supramolecular solvent based on liquid-liquid microextraction for determination of total lead in food, vegetables, grilled meat products, and water samples
(2022)
The main aim of this research article is to develop a new sample preparation method based on liquid-liquid microextraction using nanostructured supramolecular solvent for analysis of total lead in food, vegetables, grilled ...
ystematic optical study of high-x InxGa1-xAs/InP structures for infrared photodetector applications
(2022)
Optical and structural properties in high-x InxGa1-xAs (x > 0.65) samples with varying indium concentration
grown on InP (100) substrate are reported. By increasing the indium fraction, it was found by the high-resolution
X-ray ...
Sensitivity of indium molar fraction in InGaN quantum wells for near-UV light-emitting diodes
(2022)
InGaN-based quantum wells (QWs) have higher threading dislocation density (TDD) in InGaN
Light-emitting diode (LED). Despite of higher TDD, variation of Indium (In) molar fraction in the
QW generate localized excitons ...
The influence of TMGa pre-flow time and amount as surfactant on the structural and optical properties of AlN epilayer
(2022)
AIN is used as a template layer for deep UV (DUV) emitter and detector applications, because of
its wide bandgap and high thermal conductivity. In this study, trimethylgallium (TMGa) source is
used as surfactant to improve ...
Growth and characterization of PALE Si-doped AlN on sapphire substrate by MOVPE
(2022)
In this study, we report different SiH4 flow condition effects on crystal, surface, optical, and electrical characteristics of heteroepitaxial Metal-Organic Vapor Phase Epitaxy (MOVPE) grown AlN layers on sapphire substrates. ...
Synthesized of poly(vinyl benzyl dithiocarbonate-dimethyl amino ethyl methacrylate) block copolymer as adsorbent for the vortex-assisted dispersive solid phase microextraction of patulin from apple products and dried fruits
(2022)
A new and novel poly(vinyl benzyl dithiocarbonate-dimethyl amino ethyl methacrylate) block copolymer (Pvb-DMA-Xa) as adsorbent was synthesized for the vortex-assisted dispersive solid phase microextraction (VA-DSPME) of ...
Synthesized of a novel xanthate functionalized polypropylene as adsorbent for dispersive solid phase microextraction of caffeine using orbital shaker in mixed beverage matrices
(2022)
A newly synthesized xanthate functionalized chlorinated polypropylene (PP-Xa) was used as adsorbent for the orbital shaker based on dispersive solid phase microextraction (OS-DSPME) of caffein from several tea, coffee, ...
Performance enhancement of AlGaN deep-ultraviolet laser diode using compositional Al-grading of Si-doped layers
(2022)
Achieving high threshold current density and high optical confinement are big challenges in the realization of
high-performance aluminum gallium nitride (AlGaN)-based deep-ultraviolet (DUV) laser diode (LD). In this
work, ...
