Close oxygen coupled low-pressure chemical vapor deposition growth of high quality β-Ga2O3 on sapphire
(2022)
We report on the close oxygen coupled low-pressure chemical vapor deposition (COC-LPCVD) hetero-epitaxial growth of atomically smooth (− 201) oriented β−
Ga2O3 on c-plane sapphire. Utilizing a dedicated line within the ...
Assessment of arsenic in water, rice and honey samples using new and green vortex-assisted liquid phase microextraction procedure based on deep eutectic solvent: Multivariate study
(2022)
The aim of present study was to determine the arsenic in water, honey and rice samples using a new and green vortex-assisted liquid phase microextraction (VA-LPME), which is based on deep eutectic solvent (DES) by hydride ...
Effects of Heavy Iodine Atoms and π-Expanded Conjugation on Charge Transfer Dynamics in Carboxylic Acid BODIPY Derivatives as Triplet Photosensitizers
(2022)
Borondipyrromethene (BODIPY) chromophores are composed of a functional-COOH group at meso position with or without a biphenyl ring, and their compounds with heavy iodine atoms at −2, −6 positions of the BODIPY indacene ...
A new approach considering temporal correlations for GPS campaign time series
(Mayıs 2022)
GPS campaign-mode surveys are periodically collected measurements and their time series has a considerable percentage of data gaps unlike continuous time series. Studying error characteristics of a time series is imperative ...
Chemometric approach for the spectrophotometric determination of chloramphenicol in various food matrices: Using natural deep eutectic solvents
(2022)
A novel, simple and green temperature controlled-natural deep eutectic solvent emulsification liquid–liquid microextraction (TC-NADES-LLME) coupled with UV–vis spectrophotometry was optimized for preconcentration and ...
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) ...
Risk-targeted design of seismically isolated buildings
(Nisan 2022)
Seismic isolation has been used to improve the seismic performance of buildings for the last decades. However, it has been shown that the code-based displacement capacity of isolation members does not provide adequate ...
Brain tumor classification by using a novel convolutional neural network structure
(2022)
Brain tumors located in the skull are among the health problems that cause serious consequences. Rapid and accurate detection of brain tumor types will ensure that the patient receives appropriate treatment in the early ...
