Synthesis of porous NiO nanocrystals with controllable surface area and their application as supercapacitor electrodes
(2010)
We report a facile way to grow various porous NiO nanostructures including nanoslices, nanoplates, and nanocolumns, which show a structure-dependence in their specific charge capacitances. The formation of controllable ...
Metal-layer-assisted coalescence of Au nanoparticles and its effect on diameter control in vapor-liquid-solid growth of oxide nanowires
(2011)
By using the Au-catalyzed vapor-liquid-solid growth of ZnO and In2O3 nanowires as examples,we demonstrate the critical role of the coalescence of Au catalyst nanoparticles in determining the final diameter distribution of ...
Synthesis, characterization, and bipolar transporting behavior of a new twisted polycyclic aromatic hydrocarbon: 1′,4′-Diphenyl-naphtho-(2′.3′:1.2)-pyrene-6′-nitro-7′-methyl carboxylate
(2010)
An asymmetric twistacene, 1′,4′-diphenyl-naphtho-(2′.3′:1.2)-pyrene-6′-nitro-7′-methyl carboxylate (tetracene 2), was synthesized by using benzyne-trapping chemistry. Its structure, determined by X-ray crystallography, ...
Patterning colloidal metal nanoparticles for controlled growth of carbon nanotubes
(2008)
Single-walled carbon-nanotube (SWCNT) arrays are generated on catalyst patterns with controlled location, orientation, and spacing using a straightforward approach. Dip-pen nanolithography is used to fabricate catalyst ...
Synthesis, structure, and optoelectronic properties of a new twistacene 1,2,3,4,6,13-hexaphenyl-7 : 8,11 : 12-bisbenzo-pentacene
(2010)
We report the synthesis, optical and electrochemical properties, as well as the fabrication of
light-emitting devices for a new twistacene 1,2,3,4,6,13-hexaphenyl-7 : 8,11 : 12-bisbenzo-pen ...
An on-nanoparticle rolling-circle amplification platform for ultrasensitive protein detection in biological fluids
(2010)
An on-nanoparticle rolling-circle amplification (nanoRCA) strategy allows the visual detection of 30 molecules of carcinoembryonic antigen with at least 1010-fold selectivity over a range of noncognate proteins. The nanoRCA ...
Photochemically controlled synthesis of anisotropic Au nanostructures : platelet-like Au nanorods and six-star Au nanoparticles
(2010)
We report the shape-controlled synthesis of anisotropic Au nanostructures through TiO2-assisted photochemical reduction of HAuCl4. By using this method, we have successfully synthesized the platelet-like Au nanorods and ...
Graphene-based materials : synthesis, characterization, properties, and applications
(2011)
Graphene, a two-dimensional, single-layer sheet of sp2 hybridized carbon atoms, has attracted tremendous attention and research interest, owing to its exceptional physical properties, such as high electronic conductivity, ...
Binary-phased nanoparticles for enhanced thermoelectric properties
(2009)
Binary-phased PbTe-PtTe2 nanoparticles are synthesized by co-precipitation in a chemical process. These nanoparticles show much enhanced power factors as compared to that of pure PbTe nanoparticles, which may give impact ...
Amphiphilic graphene composites
(2010)
Both kinds of solubility: An amphiphilic reduced graphene oxide (rGO) composite is synthesized by using a novel coil-rod-coil conjugated triblock copolymer as the π–π binding stabilizer. Such a graphene-based composite can ...
