In-situ and ex-situ face-to-face annealing of epitaxial AlN
(2022)
AlN films have been deposited on c-plane sapphire substrates by metalorganic-vapor-phase-epitaxy (MOVPE).
The changes in the film structure have been investigated by applying different annealing processes which are exsitu ...
In-situ thermal cleaning of the sapphire substrate and temperature effect on epitaxial AlN.
(2022)
The impact of thermal surface cleaning on epitaxial AlN thin films grown on sapphire is investigated in this study
at various temperatures. The sapphire substrate is cleaned in a hydrogen environment. Structural, optical, ...

A kinetic study on the nitrification process in the upflow submerged biofilter reactor
(Environmental Technology, Taylor and Francis, 2022)
In extent of this study, ammonium removal from wastewater through biological nitrification
process was performed in upflow biofilm reactors. The effects of hydraulic retention time (HRT)
and nitrogen loading rate (NLR) ...
Thermal Protection Performances of the Macro and/or Nano Enhanced PCM in a Representative Battery Pack
(TAYLOR & FRANCIS INC, 2022)
This experimental study focused on the comparison of thermal protection performances of macro and/or nano enhanced organic PCM in a representative battery pack from low to high discharge rates. The macro/nano enhanced RT-44 ...
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
(Taylor and Francis, 4 Mart 202)
Although grinding kinetics has been the subject of many researches, there is no research examin- ing the shape kinetics of particles ground by different mills using dynamic image analysis (DIA) in the literature. In this ...
Engineering–geological investigation of the river bottom near a dam’s stabilization threshold based on two different evaluation methodologies
(Springer, 2022)
The article concerns engineering and geological studies of the river bed near the threshold stabilizing the water flow of the Włocławek hydroelectric power plant in Poland. We paid attention to the differences in river ...
The velocity of aseismic surface deformations between 2016-2020 detected by precise leveling surveys of the Akşehir Simav Fault System in the Bolvadin district, western Anatolia
(Instituto Nazionale di Geofisica e Vulcanologia, INGV, 2022)
In this research, the aim was to examine the aseismic surface deformations that occurred in the Bolvadin district center with a precise leveling technique. For this purpose, a geodetic leveling net-work consisting of eight ...
The experimental and numerical investigation on thermal responses of passive thermal protected batteries in different packs from low to high discharge rates
(Springer, 06.07.2022)
This study contains experimental and numerical investigation of the shape effect of the pack on the performances of PCM (or GNP/PCM) based passive thermally protected battery packs. Also, the performances of the PCM and ...
Investigation of adsorption properties of oxytetracycline hydrochloride on magnetic zeolite/Fe3O4 particles
(2022)
Iron oxides and ferrite-supported zeolites have been successfully used in the cheap and environmentally
friendly removal of organic pollutants such as antibiotics. In this study, the adsorption of Oxytetracycline
hydrochloride ...
