A new analytical approach for preconcentration, separation and determination of Pb(II) and Cd(II) in real samples using a new adsorbent: Synthesis, characterization and application
(Elsevier, 2021)
A green and efficient analytical approach was reported for simultaneous preconcentration, and separation of Pb(II) and Cd(II) in water, vegetables, and barbecue samples by dispersive solid-phase microextraction prior to ...
Ionic hydrophobic deep eutectic solvents in developing air-assisted liquid-phase microextraction based on experimental design: Application to flame atomic absorption spectrometry determination of cobalt in liquid and solid samples
(Elsevier, 2021)
This paper reports a new and simple microextraction procedure for cobalt determination using green ionic hydrophobic deep eutectic solvent in developing air-assisted liquid-phase microextraction and flame atomic absorption ...
An optimization approach for fast, simple and accurate determination of indigo-carmine in food samples
(Elsevier, 2021)
This study report optimization of vortex-assisted natural deep eutectic solvent based liquid-phase microextraction (VA-NADES-LPME) for determination of indigo-carmine in some food samples by UV–Visible spectrophotometer. ...
A numerical investigation of heat transfer from heated surfaces of different shapes
(Pleiades Publishing, 15.04.2021)
The object of this study was cooling of inverted and plain triangular profile copper
surfaces at a constant heat flux of 1000 W/m2. The cooling of these triangular profile surfaces
placed at the bottom of a rectangular ...
Heat affected zone and weld metal analysis of HARDOX 450 and ferritic stainless steel double sided TIG-joints
(https://www.degruyter.com, 2021)
In this study, AISI 430 and HARDOX 450 grade steel are joined using a double-sided tungsten inert gas welding process. The microstructural properties of weld metal and HAZ were evaluated by optical microscopy, energy ...
Analysis of different combustion chamber geometries using hydrogen / diesel fuel in a diesel engine
(Taylor Francis, 2021)
In this study, the effects on combustion characteristics and emission were
investigated in a direct injection diesel engine. In experimental and numerical
studies, the engine was operated at 2000 rpm. The analyzes were ...
Location selection for a textile manufacturing facility with GIS based on hybrid MCDM approach
(2021)
The establishment of a textile manufacturing facility in any city of a country is a very significant decision since it will have
a significant positive effect on the economy of both the city and the country and reduce ...
Different threshold levels of circulating total and free 25-hydroxyvitamin D for the diagnosis of vitamin D deficiency in obese adolescents
(Springer Nature, 2021)
The total serum 25-hydroxyvitamin D [25(OH)DT] level is lower in obese individuals than in their nonobese peers, despite similar bone turnover markers and bone mineral density. This study aimed to investigate whether the ...
