Optical and nano-mechanical characterization of c-axis oriented AlN film
(19.05.2022)
This paper reports the temperature effects on the optical properties of metalorganic vapour-phase epitaxy
(MOCVD) grown c-axis oriented AlN epilayer thin film studied by in-situ high-temperature spectroscopic
ellipsometry. ...
Determination of Optical Properties of MOVPE‑Grown InxGa1‑xAs/ InP Epitaxial Structures by Spectroscopic Ellipsometry
(24.08.2022)
InxGa1−xAs epitaxial layers with different AsH3 flows have been grown on InP substrate with the MOVPE system. It has been found that AsH3 flow variation affects the In concentration of InGaAs/InP structure because the ...
Theoretical analyses of the carrier localization effect on the photoluminescence of In-rich InGaAs layer grown on InP
(2022)
The free buffer InGaAs/InP structure has been elaborated by Metal Organic Vapor Phase Epitaxy (MOVPE). High
indium content is chosen to reduce the bandgap energy of the ternary material with direct bandgap to be promoted ...
Prediction of average shape values of quartz particles by vibrating disc and ball milling using dynamic image analysis based on established time-dependent shape models
(2022)
Although grinding kinetics has been the subject of many researches, there is no research examining the shape kinetics of particles ground by different mills using dynamic image analysis (DIA) in the literature. In this ...
Türkiye’de 2015 ile 2022 yılları arasında meydana gelen orman yangınlarının coğrafi bilgi sistemleri ile zamansal ve mekânsal analizi
(01.11.2023)
Dünyada orman yangınlarının can ve mal kaybına neden olan sosyal, ekonomik ve ekolojik olmak üzere maddi ve manevi birçok sonuçları vardır. Son yıllarda dünya genelinde orman yangınlarında hem sıklık hem de büyüklük açısından ...
The effect of microwave and ultrasound activation on the characteristics of biochar produced from tea waste in the presence of H3PO4 and KOH
(01.07.2023)
The mechanism of chemical and physical activation during biomass pyrolysis is crucial for the more effective use of biomass and the preparation of functional porous biochemical materials. In this study, raw tea waste (RTW) ...
Cost-Effective and Fast Fabrication of Copper–Cobalt Electrochemical Glucose Sensor
(01.10.2023)
This study aimed to develop porous Cu and Cu-Co coatings using a rapid one-step electrodeposition technique. The coatings were characterized using scanning electron microscopy and x-ray diffraction. Pencil graphite electrodes ...
Investigation of structural, morphology, and conduction mechanism of GO–Fe3O4–TiO2 composite material
(2023)
The graphene oxide composite (GO), iron oxide (Fe3O4), and titanium dioxide
(TiO2) were prepared by the sol–gel process. The surface of GO is coated with
TiO2 and Fe3O4 nanoparticles, and the composite contains 10.26% ...
Comparison of Particle Shape, Surface Area, and Color Properties of the Calcite Particles Ground by Stirred and Ball Mill
(2023)
Since the particle size, shape, specific surface area, and purity of the ground calcium carbonate (GCC) decide its usability in the paper, paint, and plastic industries, the effect of grinding is important. However, the ...
