In present era of transportation, petroleum products like Petrol and Diesel are consumed at higher rate which tends to maximize the cost of fuel, pollution and depletion of conventional fuel. To solve this issue, there is need to identify the alternative fuels for automobiles. Biofuels like Biodiesel is an alternative fuel can be added in conventional fuel at 10 to 20 % and can be used without modification in design of Diesel engine. This may reduce the consumption of Diesel by some percentage. In present work, a study is conducted to identify the influence of adding Multi-Walled Carbon Nanotubes (MWCNTs) in Soybean oil-based Bio-diesel mixture on outcome of the Engine. The process parameters of engine are optimized using Taguchi method. Different blends Soybean oil biodiesel (B20, B40 and B60) along with MWCNTs (0.5%, 1.5%). It is observed that load is critical parameter which influences the engine performance, as load increases, the BP increase, BSFC decreases and EGT increases.

Machine shop layout can be designed and modelled using either traditional or modern techniques. Traditional techniques are time consuming and are not much superior so that manufacturing industry are facing real time problems. Machine shops designed in traditional way facing the problems like unavailability of sufficient space for material handling, back tracking issue and presence of bottleneck etc. Flexsim is a simulation software used to model, visualize, simulateand monitor the Machine locations and flow of activities. In present work a modern approach of modelling a machine layout is done by simulation. Flexsim software is implemented to measure and analyze the performance of machine shop layout by performing 5 iterations. Result of each iteration was recorded and it shows that productivity is improved at fifth iteration.Machine shop layout can be designed and modelled using either traditional or modern techniques.

Halloysite nanotubes (HNTs) are modified successfully using polyethyleneimine (PEI). The HNTs and HNTs modified using PEI filled 90/10 (wt/wt) polypropylene (PP) and acrylonitrile butadiene styrene (ABS) blends and its nanocomposites are prepared by melt mixing technique in presence of dual compatibilizer. Droplet morphology is refined in matrix as well as selective localization of HNTs modified using PEI shows increase in crystallinity of PP phase and formation of β-form of PP crystals. Uniform dispersion of HNTs modified using PEI in PP resulted in improvement in impact strength, tensile modulus and thermal stability. The enhancement in tensile strength, tensile modulus, and impact strength for 1 wt% of HNTs modified using PEI filled 90/10 (wt/wt) PP/ABS blends with dual compatibilizer are 14.9, 20 and 15%, respectively.

Abstract Halloysite nanotubes (HNTs) have been successfully modified using polyethyleneimine (PEI). HNTs and PEI-modified HNTs-filled 80/20 (wt/wt) polypropylene (PP)/acrylonitrile butadiene styrene (ABS) blends and its nanocomposites in the presence of dual compatibilizer have been prepared by melt mixing technique. The refinement in matrix–droplet morphology, selective localization of PEI-modified HNTs, increase in crystallinity of PP phase, formation of β-form of PP crystals and improved dispersion of PEI-modified HNTs in PP phase has resulted in a remarkable improvement in tensile modulus, impact strength and thermal stability of PEI-modified HNTs-filled 80/20 (wt/wt) PP/ABS blends in presence of dual compatibilizer. The increase in tensile modulus, tensile strength and impact strength for PEI-modified HNTs-filled 80/20 (wt/wt) PP/ABS blends in presence of dual compatibilizer are 28.8, 26.6 and 38.5%, respectively.

Abstract Halloysite nanotubes (HNTs) filled 80/20 (wt/wt) polypropylene (PP)/acrylonitrile butadiene styrene (ABS) blends and its composites in presence and absence of dual compatibilizer (polypropylene grafted maleic anhydride (PP-g-MA), and styrene-ethylene, butylene-styrene triblock copolymer grafted with maleic anhydrite (SEBS-g-MA)) have been prepared using twin screw extruder followed by injection moulding. Significant refinements in dispersed ABS droplets diameter and interparticle distance between dispersed ABS droplets were observed in case of HNTs filled 80/20 (wt/wt) PP/ABS blends and its composites in presence of PP-g-MA and SEBS-g-MA. This has resulted in significant enhancement in tensile and impact properties of HNTs filled 80/20 (wt/wt) PP/ABS blends and its composites in presence of PP-g-MA and SEBS-g-MA. Refinement in morphology of dispersed ABS phase results in decrease in crystallinity of HNTs filled 80/20 (wt/wt) PP/ABS blends and its composites in presence of PP-g-MA and SEBS-g-MA. In addition, HNTs act as heterogeneous nucleating agent for the growth of PP crystals, and hence crystallization rate of HNTs filled 80/20 (wt/wt) PP/ABS blends and its composites in presence and absence of PP-g-MA and SEBS-g-MA increases. Thermal stability also increases in case of HNTs filled 80/20 (wt/wt) PP/ABS blends and its composites in presence and absence of PP-g-MA and SEBS-g-MA.

Hexagonal boron nitride (hBN) nanoplatelets have attracted considerable interest recently. In this work, hBN nanoplatelets have been prepared using chemical exfoliation route. The exfoliation of hBN nanoplatelets takes place along the (0 0 2) plane without destroying the crystal structure. The hBN nanoplatelets are modified using polyvinylpyrrolidone (PVP), a non-ionic surfactant in order to achieve finer dispersion of hBN nanoplatelets in ethyl alcohol, and subsequently in the epoxy matrix. The enhanced dispersion of hBN nanoplatelets achieved using PVP is due to the adsorption of PVP over the hBN nanoplatelets, and PVP miscibility with epoxy resin in an uncured state. Due to the finer dispersion of hBN nanoplatelets in the epoxy matrix, the flexural properties are higher as compared to pure epoxy. PVP assisted dispersed hBN nanoplatelets reinforced with epoxy nanocomposites have higher flexural properties as compared to pure hBN nanoplatelets-reinforced epoxy nanocomposites. The enhanced dispersion of hBN nanoplatelets using PVA also limits the decrease in glass transition temperature (Tg). Further, thermal stability of the epoxy increase with an addition of PVP modified and unmodified hBN nanoplatelets in the epoxy matrix as compared to pure epoxy. Fractography studies reveal that addition of PVP modified and unmodified hBN nanoplatelets in the epoxy matrix depict rough surface with many small facets due to resistance offered by the dispersed nanoplatelets.
