In the demanding era, we need more and more efficient materials for device fabrication.
For bulk materials, the bulk atoms dominate the properties of the materials whereas, in nanomaterials the surface atoms play a vital role in determining its properties.
This has been achieved by the capping of the nanocrystallites with organic and inorganic materials.
Starch based materials have been used as substituent for petroleum-based plastic material especially in packaging industries and thus offer an alternative solution to the disposal and biodegradability problem of petroleum based materials [27].

Introduction TiAl-based intermetallics are potential high-temperature structural materials for aerospace, automotive and other applications, due to their high specific strength, excellent oxidation and corrosion resistance, relatively low densities, and adequate creep resistance at high temperatures [1,2].
Experimental Powders of Al (200 mesh, 99.5% purity), Ti (280 mesh, 99.3% purity), TiO2 (0.5 μm, 99% purity), and Fe2O3 (320 mesh, 99% purity) were used as raw materials.
Some of the polished specimens were used for the measurement of the fracture toughness by a single-edge notched beam method with a universal material testing machine (PT-1036PC, Perfect Instrument Co.
