Mega electrorheological phenomena in graphene nanogels
Purbarun Dhar, Ajay Katiyar, Arvind Pattamatta +1
Unprecedentedly massive electrorheology has been reported for dilute graphene nanoflakes based ER fluids that have been engineered as novel, readily synthesizable polymeric gels. P…
Enhanced dielectric breakdown performance of anatase and rutile titania based nano-oils
Ajay Katiyar, Purbarun Dhar, Lakshmi Sirisha Maganti +1
Nano oils synthesized by dispersing dielectric nanostructures counter common intuition as such nano oils possess substantially higher positive dielectric breakdown voltage with red…
The Role of Percolation and Sheet Dynamics during Heat Conduction in poly-dispersed Graphene Nanofluids
Purbarun Dhar, Arvind Pattamatta, Sarit K. Das
A thermal transport mechanism leading to the enhanced thermal conductivity of Graphene nanofluids has been proposed. The Graphene sheet size is postulated to be the key to the unde…
Magnetic field induced augmented thermal conduction phenomenon in magneto nanocolloids
Ajay Katiyar, Purbarun Dhar, Tandra Nandi +1
Magnetic field induced drastically augmented thermal conductivity of magneto nanocolloids involving magnetic oxide nanoparticles, viz. Fe2O3, Fe3O4, Nickel oxide (NiO), Cobalt oxid…
Superior dielectric breakdown strength of graphene and carbon nanotube infused nano oils
Purbarun Dhar, Ajay Katiyar, Lakshmi Sirisha Maganti +2
Nano oils comprising Graphene nanoflakes and CNTs have been experimentally observed for the first time to exhibit augmented dielectric breakdown strengths compared to the base tran…
