Microstructural properties of particle-reinforced polytetrafluoroethylene composite bearings after wear
(Springer New York LLC, 2015)
High-performance engineering polymers that ensure the desired properties of journal bearings and give good wear results are investigated. We determine the microstructural properties of polymer-based particle-reinforced ...
Exergy analysis of R1234yf and R1234ze as R134a replacements in a two evaporator vapour compression refrigeration system
(Elsevier Ltd, 2015)
Exergy analysis is a useful way for determining the real thermodynamic losses and optimising environmental and economic performance in the systems such as vapour compression refrigeration systems. The present study deals ...
Processing of fireproof and high temperature durable particleboard from rice husk
(Walter de Gruyter GmbH and Co. KG, 2015)
The aim of this study is the recovery of rice husk waste by researching usability in industry as an alternative to wood. In this study urea formaldehyde resin was used mainly as binding agent for wood-panel used in industry. ...
Evaluation of QuEChERS sample preparation and liquid chromatography-triple-quadrupole mass spectrometry method for the determination of 109 pesticide residues in tomatoes
(Elsevier Ltd, 2015)
A multiresidue method based on modified QuEChERS (quick, easy, cheap, effective, rugged and safe) sample preparation, followed by liquid chromatography tandem mass spectrometry (LC–MS/MS) was developed and validated for ...
Large bandwidth mode order converter by differential waveguides
(Optical Society of American (OSA), 2015)
In this article, we propose a large bandwidth mode-order converter design by dielectric waveguides with equal lengths but different cross-sectional areas. The efficient conversion between even and odd modes is verified by ...
Second law analysis of different refrigerants in a two stage vapor compression cycle
(Turkish Society for Thermal Science and Technology, 2015)
In this study, the second law analysis has been made by means of the program developed using the software program EES (EES-V9.172-3D) in a two stage vapor-compression refrigeration cycle for the refrigerants such as R600 ...
Combined experimental and theoretical investigation of characterization and hydrogen storage properties of Zn(II) based complex and composites
(Elsevier Ltd, 2015)
Metal organic structured coordination complex was synthesized by using Zn(II), 1,10 Phenantroline and teraphtalic acid building blocks. Then the synthesized compound have been characterized with Ft-IR, TGA/DTA/DrTGA, EA, ...
Hydrogen storage in heat welded random CNT network structures
(Elsevier Ltd, 2015)
The objective of this study is to investigate hydrogen storage capability of heat welded random carbon nanotube (CNT) network structures. To achieve this objective, different three-dimensional random CNT network structures ...
Production of Ti-Fe based MgAl2O4 composite material by pressureless infiltration method
(Gazi University, 2015)
In spite of their high temperature and corrosion resistance, ceramics show a brittle nature under applied loads and this limits their usage areas. In order to compensate the weakness of ceramics with metals, which have ...
The effect of ball type in fine particles grinding on kinetic breakage parameters
(Polish Mineral Engineering Society, 2015)
In the study, the effect of different grinding media on breakage parameters was investigated. Ceramic and steel balls were used as the grinding media. It was observed that the grinding of ignimbrite obeyed first-order ...
