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…
Bridging thermal and electrical transport in dielectric nanostructure based polar colloids
Purbarun Dhar, Arvind Pattamatta, Sarit K. Das
Heat and charge transport characteristics of nanocolloids have been bridged from fundamental analysis. The relationship between the two transport phenomena in dielectric nanostruct…
Trimodal Charge Transport in Polar Liquid based Dilute Nanoparticulate Colloidal Dispersions
Purbarun Dhar, Arvind Pattamatta, Sarit K. Das
The dominant modes of charge transport in variant polar liquid based nanoparticulate colloidal dispersions (dilute) have been theorized. Theories formulating electrical characteris…
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…
Particle fluid interactivity deteriorates buoyancy driven thermal transport in nanosuspensions : A multi component lattice Boltzmann approach
Savithiri S, Purbarun Dhar, Arvind Pattamatta +1
Severe contradictions exist between experimental observations and computational predictions regarding natural convective thermal transport in nanosuspensions. The approach treating…
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…
