A comparative study of hardness/scratch/wear properties of TiCN and TiAlN coatings on DIN 1.2842 steel by CA-PVD method
(Springer, 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 ...
Gallium oxide films deposition by RF magnetron sputtering; a detailed analysis on the effects of deposition pressure and sputtering power and annealing
(Elsevier, 2021)
In this study, gallium oxide (Ga2O3) thin films were deposited on sapphire and n-Si substrates using Ga2O3 target by radio frequency magnetron sputtering (RFMS) at substrate temperature of 300 °C at variable RF power and ...
Evaluation of Arsenic and Nutrients Uptake of Tomato Plant at Various Arsenic Concentrations of Irrigation Waters
(2021)
Under various Arsenic (As) loads, growth of the tomato plant and changes in
elemental uptake were investigated in this experimental study. Plants were
transplanted into the As free soils and the loads of As were ...
Activity and stability of TiO2 samples with different phase compositions in the decomposition of formaldehyde in SCW
(ELSEVİER, 6 January )
TiO2 samples with different crystal sizes and compositions were synthesized using a sol-gel method at different calcination temperatures (350–900 °C). The activity and stability of TiO2 samples were determined by the ...
Effects of Concrete Strength and Openings in Infill Walls on Blasting Responses of RC Buildings Subjected to TNT Explosive
(2021)
The explosions caused by terrorism and/or accidental lead to serious damage and/or collapse in structures, economic losses, and most importantly endanger public safety. The blasting loads that can be larger than design ...
Optimal sensor placements for system identification of concrete arch dams
(2021)
This paper investigates the optimal sensor placements and capabilities of this procedure for dynamic characteristics identification of arch dams. For this purpose, a prototype arch dam is constructed in laboratory conditions. ...
Modal identification and fatigue behavior of Eynel steel arch highway bridge with calibrated models
(2021)
In this paper, modal parameters of the Eynel steel arch highway bridge are identified and the fatigue behavior of the bridge is investigated. Modal parameters were extracted from three ambient vibration tests carried out ...
Optimal Sensor Placement for Laminated Composite and Steel Cantilever Beams by the Effective Independence Method
(2021)
In modal testing, the quality of vibration signals and clarity of peak points to extract the natural frequencies, corresponding mode shapes and damping ratio depend on the number and location of the sensors. High measurement ...
A novel classifier architecture based on deep neural network for COVID-19 detection using laboratory findings
(Elsevier, 2021)
Unfortunately, Coronavirus disease 2019 (COVID-19) is spreading rapidly all over the world. Along with causing many deaths, it has substantially affected the social life, economics, and infrastructure worldwide in a negative ...
Templated grain growth of Bi(Zn0.5Zr0.5)O3 modified BiScO3−PbTiO3 piezoelectric ceramics for high temperature applications
(Taylor & Francis, 2021)
2.5Bi(Zn0.5Zr0.5)O3−37.5BiScO3−60PbTiO3 (BZZ-BS-PT) ceramics were successfully textured in the [001] by templated grain growth (TGG) process using 5 vol% <001>-oriented BaTiO3 (BT) plate-like templates. The templates were ...
