  Plasmonic Devices for Electromagnetic Wave Concentration

  By Jyotsna Chauhan, Ufera Khan

  Abstract: The EOT effect is enhanced by the concentration of EM waves. We explored optical transmission through arrays of nanohole pairs and found that the EOT effect through subwavelength nanoholes is enhanced by the confinement of electric field, and that the transmission is substantially higher than predicted. The optical transmission capabilities of arrays of isolated nanohole pairs and bridging nanohole pairs in gold with various geometrical configurations were explored and investigated …

  Synthesis and characterization of bi metallic Nanoparticles by 2-thiotic acid for selective growth of SWCNT

  By Jyotsna Chauhan, Sandhya Yadav

  Abstract: Nanoparticles (NPs) are tiny materials having size ranges from 1 to 100 nm. They can be classified into different classes based on their properties, shapes or sizes. There are different types of NPs like men made NPs and Natural NPs but we are discussing about monometallic NPs and Bimetallic NPs. We deal with bimetallic NPs. NPs possess unique physical and chemical properties due to their high surface area and nanoscale …

  Synthesis and Characterization of Nickel Doped BFO Nanoparticles

  By Jyotsna Chauhan, Poonam Patel

  Abstract: In the present, work we have synthesized the pure and Nickle doped bismuth ferrite at different concentration by the chemical route method. Increasing in the doping concentration leads to generation of secondary phase, thus dopant concentration is maintained to 5mol%. XRD was used to confirm the phases transformation of nanocrystalline composite materials along with measurement of the crystallite size. Scanning electronic microscopy (SEM) was used to study the morphological properties …
