Journal ArticleDOI
Facile, Noncovalent Decoration of Graphene Oxide Sheets with Nanocrystals
TL;DR: In this article, the authors used an electrostatic force-directed assembly technique at room temperature for dry decoration of graphene oxide sheets with aerosol Ag nanocrystals synthesized from an arc plasma source.
Journal ArticleDOI
Reduced graphene oxide/tin oxide composite as an enhanced anode material for lithium ion batteries prepared by homogenous coprecipitation
TL;DR: In this article, a reduced graphene oxide/tin oxide composite is prepared by homogenous coprecipitation, which can be readily adapted to other composites containing reduced graphene dioxide as a conducting additive that, in addition to supporting metal oxide nanoparticles, can also provide additional Li binding sites to enhance capacity.
Journal ArticleDOI
Activated graphene as a cathode material for Li-ion hybrid supercapacitors
Meryl D. Stoller,Shanthi Murali,Neil Quarles,Yanwu Zhu,Jeffrey R. Potts,Xianjun Zhu,Hyung-Wook Ha,Rodney S. Ruoff +7 more
TL;DR: Results show that the activated graphene material works well in a symmetrical cell with the Li-ion electrolyte with specific capacitances as high as 182 F g(-1) for the active materials at operating potentials of 4 V.
Journal ArticleDOI
Thermoacoustic Sound Generation from Monolayer Graphene for Transparent and Flexible Sound Sources
TL;DR: Transparent and flexible loudspeakers are realized with large-area monolayer graphene and the substrate effect on the thermoacoustic sound generation is studied by controlling the surface porosity of various substrates.
Journal ArticleDOI
The Origin of Improved Electrical Double-Layer Capacitance by Inclusion of Topological Defects and Dopants in Graphene for Supercapacitors
Jiafeng Chen,Yulei Han,Xianghua Kong,Xinzhou Deng,Hyo Ju Park,Yali Guo,Song Jin,Zhikai Qi,Zonghoon Lee,Zhenhua Qiao,Rodney S. Ruoff,Hengxing Ji +11 more
TL;DR: This work fabricated planar electrodes from CVD-derived single-layer graphene with deliberately introduced topological defects and nitrogen dopants in controlled concentrations and of known configurations, to estimate the influence of these defects on the electrical double-layer (EDL) capacitance.
