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 ...
ZnO/Al2O3 layered structures deposited by RF magnetron sputtering on glass: growth characteristics, optical properties, and microstructural analysis
(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. ...
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 Novel and Eco‑friendly Approach for the Simultaneous Recovery of Copper and Diamond from Waste Cutting Segments via Electrodissolution/Deposition
(2021)
A new approach is brought to diamond recovery from waste cutting segments. Unlike the commonly used hydrometallurgical processes, this approach offers the simultaneous recovery of copper with diamond. Besides, instead of ...
Development of new adsorbents via microwave treatment magnetic PET synthesis from waste PET and investigation of TC removal
(Elsevier, 2021)
In this study; new, economic and environment friendly adsorbents were synthesized using waste polyethylene
terephthalate based adsorbent, derived from waste PET bottles, WPET, nano-scale zero valent iron modified
adsorbent ...
Spatiotemporal Analysis of Cardiovascular Disease Mortality with Geographical Information Systems
(2021)
In the world, cardiovascular diseases (CVD) are known as the type of disease with the highest mortality. The mortality rate for this disease is very high in Turkey. Therefore, studies on this disease may direct the activities ...
