Yielding and flow of highly concentrated, few-layer graphene suspensions
(2015)
For a wide range of applications of graphene suspensions, a thorough understanding of their rheological properties is crucial. We probe the microstructure of dense suspensions of micron-sized, few-layer, defect-free graphene ...
Production of Ni(OH)<inf>2</inf> nanosheets by liquid phase exfoliation: From optical properties to electrochemical applications
(2016)
Here we demonstrate that liquid phase exfoliation can be used to convert layered crystals of nickel hydroxide into Ni(OH)2 nanosheets in relatively large quantities and without the need for ion intercalation. While other ...
Transparent conducting films from NbSe(3) nanowires.
(2011)
We have developed methods to disperse and partially size separate NbSe3 nanowires in aqueous
surfactant solutions. These dispersions can easily be formed into thin films. Optical and
electrical studies show these films ...
Solvent Exfoliation of Transition Metal Dichalcogenides: Dispersibility of Exfoliated Nanosheets Varies Only Weakly between Compounds
(2012)
We have studied the dispersion and exfoliation of four inorganic layered compounds, WS2,
MoS2, MoSe2 and MoTe2 in a range of organic solvents. The aim was to explore the relationship
between the chemical structure of the ...
Very thin transparent, conductive carbon nanotube films on flexible substrates
(2010)
We investigate the morphological, electrical, and optical properties of carbon nanotube thin films, focusing on films with transmittance, T > 90%. For films with T approximate to 90% we measure sheet resistance of R-s<400 ...
The preparation of hybrid films of carbon nanotubes and nanographite/graphene with excellent mechanical and electrical properties
(2010)
We have prepared mixed dispersions of single walled nanotubes and nano-graphite / graphene in the solvent N-methyl pyrrolidone. This allows the deposition of hybrid films by vacuum filtration. Scanning electron microscopy ...
Hydrogen evolution across nano-Schottky junctions at carbon supported MoS 2 catalysts in biphasic liquid systems
(2012)
The activities of a series of MoS 2-based hydrogen evolution catalysts were studied by biphasic reactions monitored by UV/Vis spectroscopy. Carbon supported MoS 2 catalysts performed best due to an abundance of catalytic ...
Production of Molybdenum Trioxide Nanosheets by Liquid Exfoliation and Their Application in High-Performance Supercapacitors
(2014)
Here, we demonstrate a simple method to exfoliate layered molybdenum trioxide (MoO3) crystallites to give multilayer MoO3 nanosheets dispersed in solvents. Exfoliation is achieved by sonicating MoO3 powder in the presence ...
Thermoelectric behavior of organic thin film nanocomposites
(2013)
Organic thin film nanocomposites, prepared by liquid-phase exfoliation, were investigated for their superior electrical properties and thermoelectric behavior. Single-walled carbon nanotubes (SWNT) were stabilized by ...
