Abstract:
Nanocomposites with magnetic components possessing nanometric dimensions, lying in the range
1–10 nm, are found to be exhibiting superior physical properties with respect to their coarser sized counterparts.
Magnetic nanocomposites based on gamma iron oxide embedded in a polymer matrix have been prepared
and characterized. The behaviour of these samples at low temperatures have been studied using Mössbauer
spectroscopy. Mössbauer studies indicate that the composites consist of very fine particles of g-Fe2O3 of which
some amount exists in the superparamagnetic phase. The cycling of the preparative conditions were found to
increase the amount of g-Fe2O3 in the matrix

Abstract:
Catalysis is a technologically important field which determines the quality of life in future. Catalyst research in pharmaceutical industry,fine chemical synthesis and emission control demands supported catalysts in bulk quantities.In the present work it was observed that clay supported catalysts mentioned in various chapters could also be used for the synthesis of similar molecules. The K10Ti catalyst can be used for the synthesis similar substituted imidazole derivatives under solvent free conditions and synthetically important Mannich bases of substrates containing various substitutes.Al-pillared saponite can be used for acetalation of other polyhydroxy compounds like glycerol,mannitol etc.Cu-Pd KSF catalyst has found application in C-C bond forming reactions which can be applied to other reactions and similar methods can be adopted for the synthesis of other catalyst by changing the transition metals. Montmorillonite K10 catalysed synthesis of triarylpyridines can be extended to the synthesis tetrasubstuted pyroles.K10Ti can also be utilized for the synthesis of similar heterocycles.
