Microstructure and in-vitro test bioactivity behavior of Co-Cr-Mo (F-75)/hydroxyapatite in phosphate buffered saline solution
(Technical University of Košice, 2014)
Cobalt based alloys were the first metallic materials successfully used in orthopedic applications. However, these alloys are bioinert, it is necessary to make them bioactive in the human body to improve their application ...
Studies on Bare and Mg-doped LiCoO2 as a cathode material for Lithium ion Batteries
(Elsevier Ltd., 2014-05)
In this paper, we report on the preparation of bare and Mg-doped Li(Mg xCo1-x)O2 (x = 0, 0.03, 0.05) phases by a molten salt method and their electrochemical properties. They were prepared at 800 °C for 6 h in air. Rietveld ...
Reconfigurable four-parasitic-elements patch antenna for high-gain beam switching application
(Institute of Electrical and Electronics Engineers (IEEE), 2014-01)
A reconfigurable beamforming of a four-para-sitic-elements patch antenna (FPPA) for WiMAX application is presented. The proposed FPPA is successfully capable to steer the
radiation pattern in azimuth planes (0°,45°, 135°, ...
Aerial platforms to ensure communications reliability in disaster areas
(American Scientific Publishers, 2014-02)
Wireless mobile networking technology can be used to reduce a negative effect that occurs in disaster areas. This study, will present an innovative technique via utilize a Low-altitude platform, in order to provide expanded ...
Effects of heat slug shapes on the heat dissipation of high power LED
(Trans Tech Publications Inc., 2014-02)
High power light emitting diodes are currently challenged by thermal issue of high heat generation which limits the reliability and efficiency. Each component in the LED package has a significant role in heat dissipation. ...
Rapid clinical assessment to facilitate the triage of adults with falciparum malaria, a retrospective analysis.
(Public Library of Science, 2014)
Background: Most adults dying from falciparum malaria will die within 48 hours of their hospitalisation. An essential component of early supportive care is the rapid identification of patients at greatest risk. In resource-poor ...
Electron and ion densities measurement in reactive magnetron zinc sputtering plasma
(Trans Tech Publications, 2014)
Investigation on the plasma properties is an essential fundamental works in order to precisely control the growth of nanoscale thin film. In the present work, we produced and study the reactive magnetron sputtering plasma ...
A study on the effect of calcination temperature on the graphitization of carbon nanotubes synthesized by the decomposition of methane
(Trans Tech Publications, 2014)
The effect of calcination temperature for Fe2O3/MgO catalysts on the formation of carbon nanotubes (CNTs) was examined. CNTs were synthesized over Fe2O3/MgO catalysts calcined at different temperatures by catalytic ...
Effect of blends ratio on mechanical and morphological properties of LDPE/Thermoplastic soya spent powder blends
(Trans Tech Publications Inc., 2014)
This study investigates the properties of blends made from low density polyethylene (LDPE) with various levels of thermoplastic soya spent powder (SSP). The thermoplastic TPSSP content was varied from 5 to 20wt % whereas ...
Effect of carbon nanotubes on the compression test and energy absorption of aluminium/polyurethane-carbon nanotubes foam sandwich
(Trans Tech Publications, 2014)
The foam was prepared by mixing the polyols, isocyanate and carbonnanotubes (CNTs) at 1000 rpm speed. The different content of the CNTs are varies from 0 3 (0, 0.5, 1.5, 2.0, 2.5, 3.0) percent by weight. The foam sandwich ...
