Though bulk titanium oxide (TiO2) is widely used in paints, the exciting properties of such material is realized only when it is in nanosize form and hence its nanostructure is being studied intensively all over the world for a large number of applic

The Alloy Process for making multifilamentary superconducting Nb 3 Sn is critically examined. It is shown the process itself has certain inherent limitations to realize a reasonably high overall J c . Further, the microstructure of the material produ
