The transport properties of films assembled from metal nanoclusters can be significantly different from the metals in their bulk or thin film forms due to quantum confinement effects and several competing energy and length scales. For a film composed of metal nanoclusters as its building blocks, the cluster size and the inter-cluster separation are(More)
Mechanical alloying with a Spex 8000 mixer/mill was used to prepare several alloys of the Fe-6 composition, where the solutes X were from groups IIB, BIB, IVB, and VI3 of the periodic table. Using x-ray diffractometry and Mijssbauer spectrometry, we determined the steady-state phases after milling for long times. The tendencies of the alloys to form the bee(More)
In the recent past surface enhanced Raman scattering (SERS) based bio-sensing has gained prominence owing to the simplicity and efficiency of the SERS technique. Dedicated and continuous research efforts have been made to develop SERS substrates that are not only stable, durable and reproducible but also facilitate real-time bio-sensing. In this context(More)
