Experimental Investigations about the Effect of New Combination of Biofuels on Simultaneous Reduction Of NOx and Smoke Emissions in DI-Diesel Engine

In this study, various percentage of DEE was added to the optimum selected ethanol-diesel blend (D-E10) and optimized its blending ratio to overcome the poor ignition quality of ethanol when utilized in a single cylinder DI diesel engine. Some physicochemical properties of test fuels such as heating value, viscosity, and density and distillation profile were determined in accordance to the A...

Effect of Graphene Oxide Nanoparticles Addition on Mechanical and Biological Properties of Calcium Phosphate Cement

In the present study, we have evaluated the effects of graphene oxide (GO) addition on the physical-mechanical-biological properties of calcium phosphate cement (CPC). The in vitro cellular responses of MG63 and in vivo tissue responses after the implantation of CPC/GO in parietal bone defects of   wistar rats were also investigated. The brushite calcium phosphate cements were prepared by mixi...
