Assoc Prof Raju Vijayaraghavan RamanujanNanomaterials are the focus of research work in Ramanujan?s group, especially magnetic and thermoelectric nanomaterials for energy, bioengineering, information storage and defense applications. Processing, characterization and property measurements are carried out in his group (presently 8 graduate students and 3 Research Fellows). Recent PhD theses include: Characterization and processing of cobalt based magnetic nanomaterials (Li Huafang),Microstructural evolution and processing of melt spun and mechanically alloyed Fe-Ni-B-Mo nanomagnetic materials (Du Siwei), Alloying effects on nanostructure formation in iron based soft magnetic materials (Yanrong Zhang) and Directed self assembly of patterned magnetic nanostructures (A. Srivastava). A strong emphasis is placed on electron microscopy and phase transformations are used as an important tool to tailor the microstructure. A bioengineering project, in collaboration with SingHealth, aims to develop magnetic nanoparticles for human liver cancer treatment. Synthesis of magnetic nanoparticles, coating these particles with a suitable polymer and cancer drug, followed by in-vitro and in-vivo testing of the coated particles is being carried out. MRI imaging is being used as an investigative tool in this work. Microelectronic reliability issues, e.g., stress-induced diffusive voiding in microelectronic materials are being studied. Magnetocaloric materials for energy applications, patterned nanostructures for ultra high density data storage media, giant energy product exchange coupled magnetic nanomaterials and nanomaterials for artificial muscles, targeted drug delivery and gene delivery are topics of ongoing research.
