LaB6 aided spontaneous conversion of bulk graphite into carbon nanotubes at normal atmospheric conditions
Shalaka A. Kamble, Soumen Karmakar, Somnath R. Bhopale +6
Herein, we report a case study in which we saw the spontaneous conversion of commercial bulk graphite into LaB6 decorated carbon nanotubes (CNTs) under normal atmospheric condition…
Unveiling the mystery of nucleation and growth of carbon nanotube and layered graphene inside carbon arc-discharge
Soumen Karmakar
A model for the formation of carbon nanotubes (CNTs) and layered graphene in an arc discharge method is developed on the basis of observed erosion of graphite anode under various e…
Tailored conversion of synthetic graphite into rotationally misoriented few-layer graphene by a cold thermal shock
Soumen Karmakar, Ashok B. Nawale, Nilesh S. Kanhe +3
Following the discovery of graphene, keen attentions have been paid in comprehending the noticeably superior electromagnetic, optical and absorptive properties of few layer graphen…
Gas phase condensation of few-layer graphene with rotational stacking faults in an electric-arc
Soumen Karmakar, Ashok B. Nawale, Niranjan P. Lalla +4
We report the synthesis efficiency of few-layer graphene (FLG) in an external magnetic field modulated DC carbon arc in different non-reactive buffer gases. The effects of buffer g…
A novel approach towards selective bulk synthesis of delaminated graphenes in an electric arc
Soumen Karmakar, Naveen V Kulkarni, Ashok B Nawale +5
Here we demonstrate the selective bulk scale synthesis of delaminated graphene sheets by a proper choice of magnetic field modulating an electric-arc. An ultra-high purity glassy g…
DC transferred arc thermal plasma assisted growth of nanoparticles with different crystalline phases
Naveen V. Kulkarni, Soumen Karmakar, Indrani Banerjee +4
The control of the crystalline phases of the nanoparticles grown in a direct-current transferred-arc plasma-assisted reactor is reported. The crystalline phases of the as synthesiz…
