| 1 | Role of NiMn_(9.3)Al_(4.0)Co_(14.1)Fe_(3.6)alloy on dehydrogenation kinetics of MgH_(2)显示文摘Hydriding and dehydriding properties of MgH_(2)-x wt.%NiMn_(9.3)Al_(4.0)Co_(14.1)Fe_(3.6)(x=10,25,50)nanocomposites have been investigated in present work.Doped alloy was prepared by arc melting method and ball milled with MgH_(2)to get nanocomposites.Onset temperature as low as 180℃was observed for MgH_(2)-50 wt%system which is 80℃lower than the as-milled MgH_(2)giving 131.34 KJ/mol activation energy.Structural analysis shows tetragonal,orthorhombic and monoclinic phases for MgH_(2),Al_(60)Mn_(11)Ni_(4)and Mg_(2)NiH_(4).Morphology by SEM were undertaken to investigate the effect of hydrogenation on nanostructured alloy.DSC studies show a single broad exothermic peak in the temperature range 48℃-353℃after alloy addition in MgH_(2).These results indicate that the hydrogenation properties of MgH_(2)nanocomposite have been improved compared to the as-milled MgH_(2). | Priyanka Meena Ramvir Singh V.K.Sharma I.P.Jain | 2018 | Journal of Magnesium and Alloys2018，6，3： | 3 |

| 3 | Densities and excess molar volumes of mixtures containing diesel,biodiesel and alkanols at temperatures from 288.15 to 313.15 K显示文摘The present work is focusing on the synthesization and physico-chemical properties of Jatropha curcas biodiesel with diesel and alcohols.The densities of binary diesel(2)+1-alkanols(C_(3) or C_(4))(3)and ternary Jatropha curcas biodiesel(1)+diesel(2)+1-alkanols(C_(3)or C_(4))(3)blends have been reported over full range of composition at temperatures within range 288.15 to 313.15 K.Also densities of Jatropha curcas biodiesel(1)+diesel or 1-alkanols(C_(3) or C_(4))(2)blends have been measured at 313.15 K.Excess molar volumes,V^E,V^E_(123)of binary and ternary blends were calculated from the measured data and the derived properties were correlated to composition using Redlich-Kister equation.A reasonable agreement was found between the measured and estimated values.Further,densities and excess molar volumes data were reasoned to discuss molecular interactions taking into consideration effect of composition and temperature. | Sunita Malik Poonam Jangra Darolia S.K.Garg V.K.Sharma | 2021 | Chinese Journal of Chemical Engineering2021，34，6： | 0 |
