Long-Term Stability of Ferroelectret Energy Harvesters
(MDPI, 2020)
Cellular polypropylene (PP) has been recently used in energy harvesting applications. In this work, we investigate its viability and long-term stability under various operating conditions. Specifically, the effect of ...
The investigation of exergoeconomic, sustainability and environmental analyses in an SI engine fuelled with different ethanol-gasoline blends
(INDERSCIENCE ENTERPRISES LTD, 2020)
In this study, performance and emission values were obtained under full load by using ethanol-gasoline blends as a fuel at different rates in a spark-ignition engine, and exergy, exergoeconomic and environmental analyses ...
Theoretical and experimental investigation of acoustic performance of multi-chamber reactive silencers
(ELSEVIER SCI LTD, 2020)
The acoustic attenuation and performance analysis for blast flow field inside a silencer is investigated. In this regard, a silencer system is designed to reduce the exhaust noise. The effect of position and the number of ...
Influence of T5 heat treatment on the microstructure and lubricated wear behavior of ternary ZnAl40Cu2 and quaternary ZnAl40Cu2Si2.5 alloysEinfluss der T5 Warmebehandlung auf das Gefuge und das geschmierte Verschleissverhalten von der ternaren ZnAl40Cu2-und der quaternaren ZnAl40Cu2Si2,5-Legierung
(WILEY-V C H VERLAG GMBH, 2020)
A ternary ZnAl40Cu2 and a quaternary ZnAl40Cu2Si2.5 alloys were produced by permanent mold casting and subjected to T5 heat treatment at a temperature of 150 degrees C for 24 hours. The structural, mechanical and lubricated ...
Mechanical and microstructural features of autoclaved aerated concrete reinforced with autoclaved polypropylene, carbon, basalt and glass fiber
(Elsevier Sci Ltd, 2015)
Autoclaved aerated concrete (MC) is a construction material obtained by being pore-forming of the mixture prepared with finely crushed siliceous aggregate lime, water and limestone with the addition of aluminum powder and ...
Microstructural, mechanical and dry sliding wear properties of the MgO reinforced aluminium matrix composites produced by vacuum infiltration
(Redakcia Kovove Materialy, 2014)
Dry sliding wear properties of MgO (10-40 vol.%) reinforced aluminium matrix composites produced by vacuum infiltration method were investigated using a pin-on-disc test machine after examining their microstructural and ...
Optimization of Screw Elements by Genetic Algorithm
(Carl Hanser Verlag, 2014)
In the present study, dimensional optimization of screw system elements, like shaft diameter, arm length and nut height, has been performed by tensile, torsional, and shear strength calculations via genetic algorithm. ...
A comparative study of lubricated friction and wear behaviour of Al-25Zn-3Cu-3Si bearing alloy
(Sage Publications Ltd, 2014)
Lubricated friction and wear behaviour of Al-25Zn-3Cu-3Si alloy was investigated on a block-on-disc test machine in comparison with 60/40 brass and SAE 65 bronze. T6 heat treatment increased the hardness, strength and wear ...
Effect of Infiltration Pressure on Thermal Conductivity of Al 2014 Matrix Composite Powered by Silicon Carbide
(Asian Journal Of Chemistry, 2012)
By using pressure infiltration method, metal matrix composites are produced by saturating Al 2014 aluminum composite to the gaps among SiC powders. SiC powders filled into stainless steel tubes are fastened between the ...
Clamp fixation to prevent unfolding of a suture knot decreases tensile strength of polypropylene sutures
(Springer, 2012)
Purpose Although sutures evolved in last decade and the product spectrum broadened largely, they can be still classified into two: monofilament and multifilament. Sutures are the mainstay of orthopedic procedures like ...
