Vegetable oil is considered as one among the promising alternatives for diesel fuel as it holds properties very close to diesel fuel. However, straight usage of vegetable oil in compression ignition (CI) engine resulted in inferior performance and emission behavior. This can be improved by modifying the straight vegetable oil into its esters, emulsion, and using them as a fuel in CI engine showcased an improved engine behavior. Waste cooking oil (WCO) is one such kind of vegetable oil gained a lot of attraction globally as it is generated in a large quantity locally. The present investigation aims at analyzing various parameters of single cylinder four stroke CI engine fueled with waste cooking oil biodiesel (WCOB), waste cooking oil biodiesel water emulsion (WCOBE) while the engine is operated with a constant speed of 1500 rpm. Furthermore, an attempt is made to study the impact of nanofluids in the behavior of the engine fueled with WCOB blended with nanofluids (WCOBN50). This work also explored a novel method of producing nanofluids using one-step chemical synthesis method. Copper oxide (CuO) nanofluids were prepared by the above mentioned method and blended with waste cooking oil biodiesel (WCOBN50) using ethylene glycol as a suitable emulsifier. Results revealed that brake thermal efficiency (BTE) and brake specific fuel consumption (BSFC) of WCOBN50 are significantly improved when compared to WCOB and WCOBE. Furthermore, a higher reduction in oxides of nitrogen (NOx), carbon monoxide (CO), hydrocarbon (HC), and smoke emissions were observed with WCOBN50 on comparison with all other tested fuels at different power outputs. It is also identified that one-step chemical synthesis method is a promising technique for preparing nanofluids with a high range of stability.

Polyamide 1010

Abstract The ternary blends of three versatile polymers of polyamide 1010 (PA1010), polypropylene (PP), and ABS resin (ABS) were studied. As a compatibilizer, PP was multimonomer melt grafted in the presence of maleic anhydride (MAH), styrene (St), and dicumyl peroxide. The effects of multimonomers melt grafting blends of MAH and St on the crystallization behavior, morphology, and mechanical properties of PA1010/ABS/PP blends were investigated. The results showed that the graft copolymer generated in situ by the anhydride groups of grafted PP (g-PP) and the amino end of PA1010 has reduced the interfacial tension of blends efficiently. The interaction of St groups of the graft copolymer with ABS was helpful to improve the compatibility of the three components during melt blending process. The size of dispersed phases in the blends was reduced remarkably and the mechanical pro­perties were greatly improved when the content of g-PP in PA1010/ABS/PP blends is increased to 10%. The tensile strength of the compatibilized PA1010/ABS/PP blends was improved by a factor of 11.7, whereas the impact strength and elongation at break were increased by 4 and 4.9 times, respectively. The introduction of multimonomer melt g-PP is shown to be an effective approach to modifying immiscible multipolymer blends, which have many potential applications.

Abstract In this study, nine ternary blends of polypropylene (PP)/poly [styrene-b-(ethylene-co butylene)-b-styrene] tri-block copolymer (SEBS)/polycarbonate (PC) were produced at different processing conditions through twin screw extruder. Accordingly, die temperature, screw speed, and blending sequences were altered based on L9 Taguchi experimental design as indications of processing variables. Consequently, the impact strength of each produced sample is considered as the responding variable. Analyzing two important aspects, namely main and interactive effects by using Taguchi analysis, was the especial point of view in our contribution; as a result, not only was the PP/SEBS/PC ternary system studied for the first time, but the SEBS-g-MAH compatibilizer also showed sufficient effects on morphology development. It was observed that the impact strength of PP/SEBS/PC ternary blends is not affected by die temperature significantly, whereas screw speed and blending sequence have had effective impacts. Besides, the optimum processing condition, which is proportional to the highest value of impact strength, is recommended through the mentioned ternary blends. These results are also confirmed while applying image analysis on morphology micrographs.

The Impact

In this paper, ternary blends of PVC mixed with α-methyl styrene-acrylonitrile (α-MSAN) and toughening modifier was prepared, with the aim to obtain a high performance PVC profile with an improved heat resistant temperature, better impact property and good processability. The results of dynamic mechanical analysis (DMA) showed the good miscibility owing to the additional intermolecular interaction between α-hydrogen of PVC and AN of α-MSAN. The glass transition temperature (Tg) and vicat softening temperature (VST) were improved remarkably with introduction of α-MSAN due to excellent heat resistant property of α-MSAN. With regard to mechanical and process properties, the impact strength and dynamic rheological property were evaluated.
