An approach to the usage of polyethylene terephthalate (PET) waste as roadway pavement material
(Elsevier, 2014)
This study investigates an application area for Polyethylene Terephthalate (PET) bottle waste which has become an environmental problem in recent decades as being a considerable part of the total plastic waste bulk. Two ...
Theoretical and experimental investigation of wear in internal gears
(2014)
Internal gears are commonly used in automotive and aeronautic industries as external sun gears of planetary mechanisms. Internal gears have some advantages such as low sliding velocities, low contact stresses, high contact ...
Tensile behavior of heat welded CNT network structures
(Elsevier, 2014)
In this study, a computational investigation on the mechanical properties of random carbon nanotube (CNT) networks is reported. For this purpose, atomistic models of 3-D CNT network structures are generated by an automated ...
The effect of anodization parameters on the formation of nanoporous TiO2 layers and their photocatalytic activities
(Elsevier B.V., 2014)
In this work, nanoporous titanium dioxide (TiO2) layers were successfully formed by electrochemical anodization method on titanium (Ti) surface in fluorine containing electrolytes with different processing parameters. The ...
A validated RP-LC method for salmeterol and fluticasone in their binary mixtures and their stress degradation behavior under ICH-recommended stress conditions
(Maik Nauka Publishing / Springer SBM, 2014)
Simple, accurate, precise and fully validated analytical methods for the simultaneous determination of salmeterol xinafoate and fluticasone propionate in combined dosage forms have been developed. These drugs were exposed ...
Experimental investigation of heat transfer in a channel with new winglet-type vortex generators
(Elsevier Ltd, 2014)
Both new punched triangular vortex generators (PTVGs) and punched rectangular vortex generators (PRVGs) have been developed. Both the triangular and rectangular vortex generators were directly punched from the longitudinal ...
Experimental and numerical investigation of geometry effects on multiple impinging air jets
(Elsevier Ltd, 2014)
The effect of jet geometry on the flow and the heat transfer characteristics was investigated experimentally and numerically for elliptic and rectangular impinging jet arrays. Detailed heat transfer measurements over a ...
Solid phase synthesis of anhydrous zinc borate from zinc and boron oxide and utilization as a flame retardant in dye and textile
(Gazi University, 2014)
Durability of materials against flame and stability at high temperatures are very important in order to increase the field of use. Non-flammability is not the only requirement; these materials should not have toxic gas ...
Synthesis and Characterization of Chitosan/Polyvinylpyrrolidone/Zeolite Composite by Solution Blending Method
(Springer New York LLC, 2014)
Polymer/clay composites have been studied for several decades; in the study, polymer/zeolite composite beads have been prepared by a simple solution blending method using chitosan, polyvinylpyrrolidone and zeolite particles ...
A new model for comminution behavior of different coals in an impact crusher
(Taylor and Francis Inc., 2014)
In this study, breakage behavior of three different coals in a laboratory impact crusher was investigated. The laboratory impact crusher carrying three rows of hammers is rotating at 2,840 rpm driven by a 1.1 kW motor. In ...
