Influence of the PALE growth temperature on quality of MOVPE grown AlN/Si (111)
(02.02.2021)
In the present study, the PALE-AlN (pulsed atomic layer epitaxy) epilayers were grown on the Si (111) substrates
at different growth temperatures by metal organic vapor phase epitaxy (MOVPE) technique. The oxygen (O) ...
Nucleation layer temperature effect on AlN epitaxial layers grown by metalorganic vapour phase epitaxy
(20.09.2021)
AlN samples have been grown on sapphire substrate using nucleation layers
(NLs) having different growth temperatures. The growth temperature of the NL
has been varied over a wide range of temperatures highlight the effects ...

(Online 202)
Background: Pregnancy is a very important period in the development
of attachment.
Objective: To determine the correlation between prenatal attachment
levels of healthy pregnant women and their styles of coping
with ...
Eco-friendly trace analysis of silver in beer/wine samples using a new co-polymeric nanocomposite based-ultrasound assisted-cloud point extraction combined with spectrophotometry
(ELSEVIER, 5 şubat 20)
In this study, a new magnetic nanocomposite based on the tris(2-hydroxymethyl)aminomethane-modified poly (styrene-co-N-maleimide) copolymer and Fe3O4 nanoparticles were prepared as a new micellar interface for preconcentration ...
ZnO/Al2O3 layered structures deposited by RF magnetron sputtering on glass: growth characteristics, optical properties, and microstructural analysis
(12.08.2021)
In this study, Al2O3 thin films of different thicknesses (50 nm, 100 nm, 150 nm, 200 nm, and 250 nm) were, first, grown using RF
magnetron sputtering technique on glass substrate at 30 °C temperature, with 120Wpower value. ...
Modeling of Schottky diode characteristic by machine learning techniques based on experimental data with wide temperature range
(18 Ekim 20)
In this study, 4 common machine learning methods have been used to model the I–V characteristic of the Au/Ni/n-GaN/undoped GaN Schottky diode. The current values of previously produced Au/Ni/n-GaN/undoped GaN Schottky diode ...
Half inverse problems for the impulsive quadratic pencil with the discontinouty coefficient

Use of new polymeric composites for preconcentration of trace Ag+ ions from the selected mushroom/vegetables by ultrasoundassisted cloud-point extraction coupled to microvolume UV-Vis spectrophotometry
(Taylor&Francis, 2021)
The magnetic nano-composites based on the tris(hydroxymethlmethyl)
aminomethane-modified maleic anhydride-co-styrene copolymers
and Fe3O4 nano-particles were prepared as new potential
chelating agents for ultrasound-a ...
A comparative study of hardness/scratch/wear properties of TiCN and TiAlN coatings on DIN 1.2842 steel by CA-PVD method
(2021)
In the present study, TiCN and TiAlN were deposited on DIN 1.2842 (AISI O2) steel, and their mechanical properties was compared by investigating coating thickness, adhesion strength, microhardness, and elastic modulus. To ...
A New Enrichment Method for Quantification of 5-Hydroxymethylfurfural by Indirect Flame Atomic Absorption Spectrometry in Honey and Jam Samples
(OXFORD UNIV PRESS INCJOURNALS DEPT, 2001 EVANS RD, CARY, NC 27513, 2021)
Background: Because of increasing amounts of 5-hydroxymethylfurfural (5-HMF) in processed foods and the complexity of the matrix, monitoring of trace 5-HMF requires accurate and reliable methods. Hence, an efficient sample ...
