The effects of glycerol, sorbitol and cinnamon essential oil on the physical and barrier properties (colour parameters, moisture content, water solubility, water vapour transmission rate of corn and rice starch edible films have been investigated. Corn starch composite films plasticized with glycerol and rice starch composite films plasticized with sorbitol, have demonstrated high colour change. The composite films have lower moisture contents. The control films containing only glycerol as plasticizer have higher moisture content than the control films containing only sorbitol. Glycerol is found to be a more suitable plasticizer for starch films as lower water vapour transmission rate values are preferred in the food industry and the composite rice starch films, has the highest water solubility. The interaction of film components has been evaluated by Fourier transform infrared spectroscopy.

J. Abstract: In the presence of biphasic medium, ethyl methacrylate has been polymerized using phase transfer catalyst under silent/ultrasonic condition (53 KHz, 100 W) at 60℃ (±1℃) as well as under inert atmosphere. A series of quaternary ammonium salts namely 1,4-Bis(dimethylhexyl)ethylenediammonium bromide (DMHEDAB), 1,4-Bis(dimethylheptyl) ethylenediammonium bromide (DMH1EDAB) and 1,4-Bis(dimethyloctyl) ethylenediammonium bromide (DMOEDAB) have been selected as phase transfer catalysts (PTCs). Rate of polymerization is assessed in silent and sonolytic conditions by varying the concentrations of monomer, initiator, PTCs, solvents, and temperature. The synergism of sonolysis and phase transfer catalysts increased the rate when compared to silent polymerization. Based on the results, thermodynamic values are measured, and the order of efficacy of all three catalysts are observed as DMOEDAB > DMH1EDAB > DMHEDAB.

This work alters the manufacturing process by utilizing various cellulose ratios derived from different agricultural residues. Craft papers have been made with the use of a fairly straightforward and environmentally benign process known as the handmade technique, which includes these raw residues in various ratios. The physico-mechanical properties are measured for synthesized sheets with an appropriate basis weight (63–80 g/m2), thickness (20–300 m), burst strength (58.9–105.2 kPa), burst index (1.03–1.67 kPa m2/g), and bulk (1.06 – 3.12 cm3/g), respectively. It is demonstrated that the used ingredients are cost-effective and eco-friendly. In addition, it is found that the quality of the handmade paper sample composition formed with a blend of 20% rice husk, 30% sugarcane bagasse, and 50% banana fiber, is relatively high. This study demonstrates that agricultural waste can provide viable alternatives for the industries that produce handmade paper.

Sowmya; Madhu, P. Abstract: The aim of this work is to assess the effect of graphene oxide (GO) nanoparticles on performance and emission characteristics of a ceramic coated diesel engine fuelled with ternary blends of pyrolysis oil-methyl ester-diesel. Tyre pyrolysis oil and hemp oil methyl ester (biodiesel) have been produced and PBD20 (10%pyrolysis oil + 10%biodiesel + 80% diesel) blend has been prepared for engine analysis. This work also evaluate the performance and emission characteristics of the engine operated with PBD20 with different dosage of GO in both conventional and partially stabilized zirconia (PSZ) coated engines. Initially, base diesel, 20% blend and 20% blend with different GO dosage level are tested in a standard engine and later, the same fuels are tested in a ceramic coated engine under varying load conditions from 0 to 100%. The performance parameters such as brake thermal efficiency (BTE), brake specific fuel consumption (BSFC), emission parameters such as carbon monoxide (CO), hydrocarbons (HC) and oxides of nitrogen (NOx) are all measured. The results showed that the engine is able to run on blends of tyre pyrolysis oil and hemp oil at different loads, showing similar performance to diesel. From the research, it is noted that PBD20 with 50 ppm GO in a coated engine showed 4.41% higher performance than diesel operated in a standard engine. The BSFC of the engine running on the same blend showed similar trend to diesel. The emission of CO and HC are reduced by 40% and 25.58%, respectively, when the engine operated using PBD20GO50 in coated engine. Page(s): 553-563 2024-06-01T00:00:00Z
