Journal ArticleDOI
Polyaniline-grafted reduced graphene oxide for efficient electrochemical supercapacitors
Nanjundan Ashok Kumar,Hyun-Jung Choi,Yeon Ran Shin,Dong Wook Chang,Liming Dai,Jong-Beom Baek +5 more
TL;DR: Electron microscopic studies demonstrated that the resultant composite has fibrillar morphology with a room-temperature electrical conductivity as high as 8.66 S/cm and capacitance of 250 F/g with good cycling stability.
Journal ArticleDOI
Biomass derived carbon nanoparticle as anodes for high performance sodium and lithium ion batteries
Rohit Ranganathan Gaddam,Dongfang Yang,Ramanuj Narayan,Kothapalli V S N Raju,Nanjundan Ashok Kumar,Xiu Song Zhao +5 more
TL;DR: In this paper, a flame deposition method was used to obtain surface-carboxylated carbon nanoparticles (c-CNPs) from coconut oil and they were further modified with a piranha solution.
Journal ArticleDOI
Preparation and characterization of carbon nanotube-grafted-chitosan – Natural hydroxyapatite composite for bone tissue engineering
TL;DR: Observations suggest that the novel chitosan/HAp and f-MWCNT-g-chitOSan/ HAp composite scaffolds are promising biomaterials for bone tissue engineering.
Journal ArticleDOI
Functionalization of chemically derived graphene for improving its electrocapacitive energy storage properties
TL;DR: A review of the latest developments in the functionalization of chemically derived graphene for improving its electrocapacitive properties is presented in this article, where a discussion on how to functionalize chemically derived GAs for improving their double-layer capacitance and pseudocapacitance is provided.
Journal ArticleDOI
Plasma-assisted simultaneous reduction and nitrogen doping of graphene oxide nanosheets
Nanjundan Ashok Kumar,Hugo Nolan,Niall McEvoy,Ehsan Rezvani,Richard L. Doyle,Michael E. G. Lyons,Georg S. Duesberg +6 more
TL;DR: In this article, an environmentally benign and scalable route for the production of gram scale quantities of nitrogen-doped graphene using a downstream microwave plasma source is reported and simultaneously reduction and doping of graphene oxide is achieved and the process negates the need for high temperatures and toxic solvents associated with existing methods.
