Biodiesel, the methyl ester of vegetable oil is a renewable, low environmental impact and potential as a green alternative fuel for diesel engine. High oil prices and growing concerns over climate change are driving investment and innovation in the biofuels sector as countries and industry increasingly look towards renewable bioenergy to replace fossil fuels. This study examines fuel properties...

Polyetherimide (PEI) blends modified by either polycarbonate (PC) or polyethylene terephthalate glycol-modified (PETG) were prepared. The latter modifier (PETG) was an industrial grade widely used for fused deposition modelling (FDM) printing. PEI blends were compared to Ultem 9085, which is the standard PEI grade for FDM printing in advanced applications. All the blends were thoroughly charact...

The effects of chain architecture on the miscibility of polymer blends were studied by means of Monte Carlo simulations. Using the bond fluctuation model on a simple cubic lattice, we were able to simulate symmetric linear/linear andsfor the first timesstar/star blends with a moderate number of arms. The simulations were made at a volume fraction of occupied lattice sites æ ) 0.5, which corresp...

In this work, the thermal behavior of rice husk, sewage sludge, and their blends during combustion processes was investigated by means of thermogravimetric analysis (TGA), and the slagging characteristics were studied through X-ray fluorescence (XRF) and melting temperature. The effects of the proportion of rice husk and sewage sludge blends on the combustion process, ignition and burnout chara...

Vehicle Emission is one of the main causes of environmental damage. Vehicle engines produce carbon dioxide (CO2), hydrocarbon (HC), Nitrogen oxides (NOx) and many other harmful substances. An investigation was conducted using a compression-ignition engine fuelled with different ratios of blends of diesel and biodiesel at different EGR rates. The effects of different ratios of fuel blends and EG...

In this work, ternary polymer blends based on polypropylene (PP)/ polyethylene terephthalate (PET) /poly(styrene-b (ethylene-co-butylene)-b-styrene) (SEBS) triblock copolymer and a reactive maleic anhydride grafted SEBS (SEBS-g-MAH) at various compositions were prepared by co-rotating twin screw extruder. The effects of PET, SEBS and SEBS-g-MAH compatibilizer on morphology of the blends were ex...

This paper studies the effect of type and concentration selected frothers, gas flowrate, pore size porous frit on bubble sizes (Sauter mean diameter, SMD) bubbling flow produced in a micro-flotation cell, determination distribution (BSD) presence frothers. The commercial frothers polypropylene glycols (PPG 200, 400, 600), tri propylene glycol (BTPG), triethylene (BTEG), dipropylene (BDPG), Meth...

The compatibilities of polymer blends, Polypropylene(PP) and Polyamide12(PA12), was simulated by molecular dynamics(MD) simulations. Density, cohesive energy density (CED) ,and solubility parameters(δ) of pure substances and PP/PA12 blends were calculated by MD simulations with the COMPASS force field for the prediction of polymer blends compatibility . Results showed that PP/PA12 is not miscri...

The properties of blends of banana, potato, and rice starches were studied to assess their suitability as an alternate for chemically modified starches. The blends of banana, potato, and rice starches were prepared in the respective ratio of 1:3:2, 3:2:1, and 2:1:3. The blend with higher proportion of banana and rice starches (BPR213) showed highest water absorption capacity and oil absorption ...

Blends of poly(hydroxy ester ether) (PHEE), a recently developed bisphenol A ether-based synthetic biodegradable thermoplastic polymer, with a soybean protein isolate and two hydrolyzed wheat glutens were studied. Blends of the proteins with PHEE were produced from 20 to 70% by weight of protein content. Young’s moduli of the protein/PHEE blends fall in the range of 0.8–1.5 GPa with tensile str...
