Elastoplastic stress analysis of functionally graded disc under internal pressure-complas XII
(2013)
The study deals with elastoplastic stress analysis of a hollow disk made of functionally graded materials (FGMs) subjected to an internal pressure. The material properties of disc are assumed to vary radially according to ...
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. ...
Effect of aging at different temperatures on LAOS properties and secondary protein structure of hard wheat flour dough
(Academic Press, 2020)
The effects of aging from t = 0–108 h at two different temperatures (4 and 25 °C) on the non-linear viscoelastic rheological properties and secondary protein structure of hard wheat flour dough (HWD) were investigated using ...
Multi-objective crashworthiness optimization of lattice structure filled thin-walled tubes
(Elsevier Ltd, 2020)
Thin-walled tubes have been mostly used in passive vehicle safety systems as crash energy absorber. With the use of additive manufacturing technology, it is possible to produce novel filler materials to further enhance the ...
Synthesis and characterization of silicon carbide powders converted from metakaolin-based geopolymer
(Blackwell Publishing Inc., 2016)
Silicon carbide (SiC) ceramic powders were synthesized by carbothermal reduction in specific geopolymers containing carbon nanopowders. Geopolymers containing carbon and having a composition M2O·Al2O3·4.5SiO2·12H2O+18C, ...
Structural, electronic, and electrochemical analyses of sputter-coated Pt and Pt–Co/GCE electrodes with ultra-low metal loadings for PEM fuel cell applications
(Springer Netherlands, 2017)
In this study, unsupported platinum and platinum–cobalt ultra-thin catalyst layers with varying metal loadings were prepared by a sequential magnetron sputtering technique. The deposited catalyst layers were characterized ...
Electrochemical copper (II) sensor based on chitosan covered gold nanoparticles
(Kluwer Academic Publishers, 2014)
This study outlines a new sensing platform based on glassy carbon electrodes modified by gold nanoparticles (AuNPs) for the determination of heavy metal. A glassy carbon electrode was modified by chitosan stabilized AuNPs. ...
Acoustic analysis of a liquefied petroleum gas-fired pulse combustor
(2008)
Experimental investigation of acoustic characteristics of a Helmholtz type liquefied petroleum gas-fired pulse combustor is presented. In the experiments, the length of the tail pipe was changed from 1.9 m to 1.3 m by 10 ...
Atom-economical synthesis of complex heterocycles with N-O moiety
(Wiley Blackwell, 2015)
A concise and facile method for the synthesis of heterocyclic compounds with N-O tether was introduced. The two important steps of the synthesis are a Mitsunobu reaction and C-H activation. The Mitsunobu protocol allows ...
Effect of electrolytic nickel coating on fatigue life of iron based powder metal parts
(2011)
Electrolytic coating is one of the methods mainly used to provide corrosion resistance for the powder metal parts. The coatings have strong effects on mechanical properties of coated parts as well as on surface properties. ...
