Journal ArticleDOI

Large area few-layer graphene/graphite films as transparent thin conducting electrodes

Weiwei Cai, +4 more
- 24 Sep 2009 - 
TL;DR: In this paper, carbon atoms decomposed from methane in a metal substrate at high temperatures were precipitated on metal surfaces upon cooling, and large area uniform few-layer graphene (FLG)/graphite films were transferred to glass slides after dissolving the metal substrate in an aqueous solution of Fe(NO3)3.
Journal ArticleDOI

Incorporation of manganese dioxide within ultraporous activated graphene for high-performance electrochemical capacitors.

Xin Zhao, +6 more
- 10 May 2012 - 
TL;DR: Manganese dioxide particles 2-3 nm in size were deposited onto a porous "activated microwave expanded graphite oxide" (aMEGO) carbon scaffold via a self-controlled redox process to produce capacitors that yielded a specific capacitance of 256 F/g and a capacitance retention of 87.7% after 1000 cycles in 1 M H(2)SO(4).
Journal ArticleDOI

Toward Practical Gas Sensing with Highly Reduced Graphene Oxide: A New Signal Processing Method To Circumvent Run-to-Run and Device-to-Device Variations

Ganhua Lu, +6 more
- 04 Jan 2011 - 
TL;DR: It is suggested that the work reported here is a significant step toward the real-world application of graphene-based chemical sensors, including the sensor signal processing method and the inherent simplicity of device fabrication.
Journal ArticleDOI

Chemical structures of hydrazine-treated graphene oxide and generation of aromatic nitrogen doping

Sungjin Park, +13 more
- 24 Jan 2012 - 
TL;DR: These experiments suggest that hydrazine treatment of graphene oxide causes insertion of an aromatic N(2) moiety in a five-membered ring at the platelet edges and also restores graphitic networks on the basal planes.
Journal ArticleDOI

Nitrogen doping of graphene and its effect on quantum capacitance, and a new insight on the enhanced capacitance of N-doped carbon

Lili Zhang, +10 more
- 18 Oct 2012 - 
TL;DR: In this article, the area-normalized capacitance of lightly N-doped activated graphene with similar porous structure was measured and a trend of upwards shifts of the Dirac Point with increasing N concentration was observed.
