Investigations on the Hydrogenation Characteristics of Rare Earth Penta-nickelides Type Materials and its Use as Alternate Fuel in IC Engine

摘要

The present communication deals with the investigations made on synthesis,structural characteristics and the electrical resistivity variation in RNi_5 (R=rare earth,mischmetal) thin films on hydrogenation,the differential thermal analysis and application of RNi_5 hydrides in IC engines using hydrogen as a fuel.Explanation for the observed behaviour of resistivity variation of RNi_5 on hydrogenation has been advanced on the basis of the band structure of LaNi_5 and hydride of LaNi_5.The differential thermal analysis of the amorphous MmNi4.5Al0.5(Mm=mischmetal) has been discussed.
