Thin wideband infrared metamaterial absorber with coplanar metallic patches of different sizes
(Institute of Electrical and Electronics Engineers Inc., 2016)
Infrared absorber concept is a vibrant research topic because of the importance of real world applications such as infrared detectors, thermal coolers and energy harvesters. In this paper, we propose and numerically analyze ...
Design of sma based actuators used in robotics
(2013)
This work introduces to Shape Memory Alloy (SMA) using in Robotics as actuators. We investigated a quadruped platform actuated by SMAs which act with variable elasticity. SMAs ought to prove necessary forces for all gaits. ...
On operator GA-convex functions in Hilbert spaces
(American Institute of Physics Inc., 2018)
In this paper, it is defined the operator GA-convex functions for continuous functions of self-adjoint operators in Hilbert spaces. And then it is obtained some new Hermite-Hadamard type inequalities for this class of ...
Effect of tooth profile modification on wear in internal gears
(IOP Publishing Ltd, 2018)
Internal gears are often used in the automotive industry when two gears are required to rotate in the same direction. Tooth shapes, slippage speeds at the beginning and end of meshing are different according to the external ...
Numerical investigation of amounts of heat, power and temperature distribution in IT-SOFC
(Electrochemical Society Inc., 2013)
In this study, thermodynamic and heat transfer concepts were combined to understanding correlation of heat, power and temperature gradient on the cell. All of heat sources and amounts has been determined for electrolyte ...
Electrical conductivity and corrosion performances of in situ and ex situ AA7075 aluminum composites
(Polish Academy of Sciences, 2017)
The present study investigates corrosion behaviors and electric conductivity of AA7075 in situ (TiAl3) and ex situ (B4C) composites produced by powder metallurgy method. In production of in situ composites, various amounts ...
Corrosion behaviour and electrical conductivity of reinforced TiAl3 and B4C hybrid aluminium composites
(Polish Academy of Sciences, 2017)
In this study, corrosion and electric conductivity of aluminum hybrid composites (in situ TiAl3 and ex situ B4C) produced by powder metallurgy are investigated. Hybrid (in situ and ex situ) aluminum composite powders are ...
Effect of surfactant types on the size of tin oxide nanoparticles
(Polish Academy of Sciences, 2017)
In this study, tin oxide (SnO2) nanoparticles were synthesized by hydrothermal method in the presence of hydrazine and ammonia by adding surfactant for 12 h in a Teflon autoclave at 100°C reaction temperature. Tin(II) ...
Preparation and swelling properties of zeolite-poly(2-hydroxyethyl methacrylate-co-acrylic acid) hydrogel composites
(Polish Academy of Sciences, 2016)
Zeolite-Poly(2-hydroxyethyl methacrylate (HEMA)-co-acrylic acid (AA)) hydrogel composite materials were synthesized by in situ free radical addition polymerization technique. The swelling values obtained highly for the ...
Synthesis, characterization and sensing behavior of WO3 nanocrystalline powder for toluene vapor
(Polish Academy of Sciences, 2017)
Tungsten oxide (WO3) nanocrystalline powder was successfully synthesized by direct precipitation technique starting from sodium tungstate dehydrate (Na2WO4•2H2O) as precursor at 80°C for 48 h. The morphological characteristics, ...
