Characterization of atomic layer deposition coated cutting tools by X-ray photoelectron spectroscopy and examination of cutting performance
(Taylor & Francis Inc, 2019)
The performance of cutting tools was examined, involving synthesis of a 10 nm thin film of Aluminum oxide using atomic layer deposition. Characterization of coated and uncoated cutting tools was done by several methods. ...
Electrochemical activity enhancement of monodisperse boron nitride quantum dots on graphene oxide: Its application for simultaneous detection of organophosphate pesticides in real samples
(Elsevier, 2019)
Organophosphate pesticides are toxic chemicals and not allowed in nearly all countries. It accumulates in water and soil owing to its low solubility and bioaccumulation causing serious health problems. A novel voltammetric ...
Negative effect of protective bag on trawl codend selectivity
(Natl Inst Science Communication-Niscair, 2019)
This study investigated the differences of selectivity between a plain codend and a codend surrounded with a protective bag. The experiments were carried out in the Iskenderun Bay, located in the eastern Mediterranean Sea, ...
Basic Leaching Behavior of Mechanically Activated Zinc Plant Residue
(Springer, 2019)
Zinc plant residue is a secondary metal source because it has precious metals such as zinc and lead. However, since this residue contains partial ferrite structure, there is no large-scale recovery in metallurgy industry. ...
Performance Results of Photovoltaic/Fuel Cell Based Hybrid Energy System under Variable Conditions
(Ieee, 2019)
In this paper, dynamic operation and optimization of a grid connected hybrid system including photovoltaics (PV) and fuel cell (FC) is presented. For this purpose, abc/dq transform based power flow controller is used in ...
Investigation of microstructure and mechanical properties of friction stir welded dissimilar St37/St52 joints
(Institute of Physics Publishing, 2019)
Although friction stir welding (FSW) has widely been applied to aluminum alloys in several industries over the past three decades, it is not yet used in industry for joining of steels. The aim of this study is to characterize ...
Determination of seasonal metal concentrations in seawater of the Iskenderun Bay in the eastern Mediterranean, Turkey
(Parlar Scientific Publications, 2019)
In this study, seasonal variations of some heavy metal concentrations (Fe, Zn, Cd, Cu, Co, Ni, Al, Mn, Pb, and Cr) were determined. A total of 108 seawater samples were taken in three different stations with depths of about ...
Thiadiazoloquinoxaline and benzodithiophene bearing polymers for electrochromic and organic photovoltaic applications
(Taylor & Francis Ltd, 2019)
Two novel thiadiazoloquinoxaline and benzodithiophene (BDT) bearing copolymers were designed and synthesized. Different BDT units (alkoxy and thiophene substituted) were used as donor materials and the effect of alkoxy and ...
Properties and Corrosion Resistance of AISI H13 Hot-Work Tool Steel with Borided B4C Powders
(Korean Institute of Metals and Materials, 2019)
Abstract: In this study, the surface of AISI H13 steel was borided with powder blends of B4C and NaBF4 using the powder-pack method at 800, 900 and 1000 °C for 2, 4 and 6 h. The structural and mechanical characteristics ...
The Rheology and Performance of Geothermal Spring Water-Based Drilling Fluids
(Wiley-Hindawi, 2019)
In this study, the rheological properties and performances of mud prepared with geothermal spring water to be used by geothermal drilling operators were examined at ambient and elevated temperatures. In this context, mud ...
