Relationships between mechanical and tribological properties of Zn-15Al-based ternary and quaternary alloys
(Carl Hanser Verlag, 2016)
Five ternary Zn-15Al-(1- 5)Cu and six quaternary Zn15Al-3Cu-(0.5-3) Si alloys were prepared by permanent mold casting for this work. Their unlubricated sliding friction and wear properties were investigated at a pressure ...
Centri-voltammetric detection of epinephrine
(Royal Soc Chemistry, 2016)
The present study demonstrates a novel approach that has been proposed for epinephrine detection by using centri-voltammetry. the principle of the method is based on the accumulation of an analyte, here epinephrine, onto ...
Improving the stability of solar cells using metal-organic frameworks
(Royal Soc Chemistry, 2016)
Although Cu2S-containing chalcogenide solar cells are appealing and cost-effective for photovoltaics (PVs), these materials suffer from rapid performance degradation as a result of the diffusion of copper ions into the CdS ...
Investigation of photoluminescence mechanisms from SiO2/Si:SiO2/SiO2 structures in weak quantum confined regime by deconvolution of photoluminescence spectra
(Amer Scientific Publishers, 2016)
Si nanocrystals embedded in SiO2 matrix were prepared by co-sputtering method followed by a post annealing process in N-2 ambient. By fixing sputtering parameters, the effects of annealing time and annealing temperature ...
The investigation crack problem through numerical analysis
(Techno-Press, 2016)
This paper presents a comparative study of finite element method (FEM) and analytical method for the plane problem of a layered composite containing an internal perpendicular crack in literature. the layered composite ...
The investigation of stability of n-CdS/p-Cu2S solar cells prepared by cold substrate method
(IOP Publishing, 2021)
In this study, two different n-CdS/p-Cu2S solar cells were prepared by evaporating Cu at different substrate temperatures (200 K and 300 K) by vacuum evaporation method on a single crystal CdS semiconductor. Field emission ...
Stability investigation of a deep shaft using different methods
(ASCE- American Society of Civil Engineers, 2021)
The New Zigana Tunnel is, at 14.5 km long, the longest highway tunnel project in Turkey. In this project, it is planned to construct two service shafts to provide access to outside the tunnel and temporary ventilation. ...
Optimization of strength, ductility and wear resistance of low-carbon grade A shipbuilding steel by post-ECAP annealing
(EDP Sciences, 2021)
Effect of equal channel angular pressing (ECAP) and subsequent annealing on the microstructure, mechanical properties and tribological behavior of grade A shipbuilding steel was investigated. Coarse-grained microstructure ...
Effect of mineralogical composition of clinoptilolite-bearing tuffs on their performance as a natural pozzolan in cementitious systems
(Techno-Press, 2021)
In this study, pozzolanic reactivity and strength activity of zeolitic tuffs containing similar amount of zeolitic phase (clinoptilolite) and different types and amounts of impurities were examined in order to understand ...
Investigation of continuous and discontinuous contact cases in the contact mechanics of graded materials using analytical method and FEM
(Techno-Press, 2021)
The aim of this paper was to examine the continuous and discontinuous contact problems between the functionally graded (FG) layer pressed with a uniformly distributed load and homogeneous half plane using an analytical ...
