Physicochemical Properties of Coconut and Waste Cooking Oils for Biofuel Production and Lubrication

Fuels
Vegetable oils are an important alternative to the massive use of fuels and lubricants from non-renewable energy sources. In this study, the physicochemical properties of coconut oil and waste cooking oil are investigated for biofuels and biolubricant ...

Electrodeposition of Ni, Fe and Ni-Fe Alloys in Two Ionic Liquids: (tri (n-butyl) [2-methoxy-2-oxoethyl] Ammonium bis (trifluoromethylsulfonyl) [BuGBOEt] [Tf2N] and (1-butyl-1-methylpyrrolidinium bis trifluoromethylsulfonyl) imide ([P1,4] [Tf2N])

International Journal of Electrochemical Science, 2016
Ni, Fe and Ni-Fe alloys electrodeposition were tested in two ionic liquids. The first one is a commercial (1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide ([P1,4][Tf2N])) and the second is a homemade (tri(n-butyl)[2-ethoxy-2oxoethyl ...
