compatibilization of toughened polypropylene biocarbon biocomposites a Full Factorial Design optimization of mechanical properties
Polymer Testing, 2017Co-Authors: Ehsan Behazin, Manjusri Misra, Amar K. MohantyAbstract:Abstract The structure-property relationships of toughened polypropylene/biocarbon biocomposites prepared via melt extrusion are investigated with a focus on the effects of biocarbon particle size, functional polymer type and concentration. A Full Factorial Design was utilized to study each factor's main effect and how their interactions with other factors affect the final mechanical properties of the biocomposites. The statistical analysis confirmed the synergistic interactions between the biocarbon and the functional polymer which improves the impact toughness of the composites by 120% while maintaining or improving the stiffness of the composite. Among the investigated factors, the type of functional polymers had the greatest impact on the properties by affecting the morphology of phases. Based on these analyses, the biocarbon with particle size range of 106–125 μm together with 5.0 wt% of maleic anhydride grafted polypropylene was selected as the optimum composite formulation providing the best stiffness-toughness balance among the tested samples.

investigation of promoted cu zno al2o3 methanol steam reforming nanocatalysts by Full Factorial Design
Chemical Engineering & Technology, 2012Co-Authors: Sharifi H Pajaie, Majid TaghizadehAbstract:A Cu/ZnO/Al2O3 nanocatalyst was applied for hydrogen production via steam reforming of methanol in a fixed-bed reactor. Modified forms of the catalyst were prepared by adding small amounts of Ba, Zr, and Ce oxides. The catalysts were characterized by means of N2 adsorption-desorption, X-ray diffraction, and scanning electron microscope techniques. Full Factorial Design was used to optimize the required number of experiments and evaluate the catalytic activity in a fixed-bed reactor. The oxide additives reduced the production of carbon monoxide and increased the selectivity of carbon dioxide as well as the yield of hydrogen production. Among the studied catalysts, the Cu/ZnO/Al2O3/CeO2/ZrO2 catalyst presented the best performance.

electrical discharge machining characteristics of nickel titanium shape memory alloy based on Full Factorial Design
Journal of Intelligent Material Systems and Structures, 2013Co-Authors: Ali Alidoosti, A Ghafarinazari, Fathollah Moztarzadeh, Newsha Jalali, Sina Moztarzadeh, Masoud MozafariAbstract:Among many shape memory alloys, nickel–titanium (NiTi) alloys are popular due to their superior properties in shape memory effect and superelasticity. They are presently often used in microengineering and medical technology especially in orthopedic and orthodontic implants due to their specific properties. In this study, the electric discharge machine characteristics of NiTi shape memory alloys have been Fully investigated by Full Factorial Design. Analysis of mean showed that the material removal rate of NiTi in the electric discharge machine process significantly related to the electrodischarge energy, involving the pulse current and pulse duration. Many electrodischarge craters and recast layers were observed on the electric discharge machine surface of NiTi samples. In addition, there was no significant difference between copper (Cu) and tungsten–copper (W-Cu) electrodes in material removal rate but work stability of W-Cu electrode was longer. On the contrary, quantity of impurity on the surface of th...

Investigation of Thermal Conductivity and Viscosity of Al2O3/Water Nanofluids Using Full Factorial Design and Utility Concept
NANO, 2016Co-Authors: Deepak Khurana, Rajesh Choudhary, Sudhakar SubudhiAbstract:In the present study, the effect of particle concentration, particle diameter and temperature on the thermal conductivity and viscosity of Al2O3/water nanofluids was investigated experimentally using Design of experiment approach (Full Factorial Design). Variables were selected at two levels each: particle concentration (0.1–1%), particle diameter (20–40nm) and temperature (10–40∘C). It was observed that the thermal conductivity of the Al2O3/water nanofluids increases with increasing concentration and temperature and decreases with increase in particle diameter, while viscosity increases with increasing particle diameter. Results showed that the interaction effect of concentration and temperature also has significant effect on the thermal conductivity of Al2O3/water nanofluids. For viscosity, the interaction of particle diameter and temperature was important. Utility concept was used to optimize the properties collectively for better heat transfer performance. The optimal combination for high thermal cond...
