Low energy electron microscopy, scanning tunneling microscopy, and angle resolved photoelectron spectroscopy studies prove the millimeter-scale continuity and uniform thickness of the graphene synthesized on cubic-SiC(001)/Si(001) wafers. The graphene overlayer on SiC(001) consists of only a few monolayers with the atomic and electronic properties of quasi-freestanding graphene.

PdAg alloys have been controllably grown at different locations on gold nanorods, producing high-quality dumbbell-like and branched nanorods. The branched nanorods exhibit a higher electrochemical activity for ethanol oxidation, but a worse anti-poisoning performance than the dumbbell-like nanorods.

An advanced graphene-based Li-ion hybrid supercapacitor system, consisting of a high specific capacity graphene-inserted Li4Ti5O12 anode and a high surface area graphene每sucrose cathode, has been successfully fabricated and shows ultrahigh performance. Moreover, the graphene每Li4Ti5O12 nanocomposite also delivers excellent reversible capacities compared with the theoretical 175 mA﹞h﹞g每1 capacity of pure Li4Ti5O12 at the same rates.


Nanoplasmonic colloidal suspensions for the enhance¬ment of the luminescent emission from single-walled carbon nanotubes

Mareen Glaeske and Antonio Setaro (

Department of Physics, Freie Universität Berlin, Arnimallee 14, 14195 Berlin, Germany

DOI 10.1007/s12274-013-0335-5

Nano Research 2013, 6(7): 593每601

Address correspondence to

Here we introduce 羽-hybrids, a new class of hybrid nanoplasmonic colloidal systems that take advantage of the coupling between the excitons in single-walled carbon nanotubes and the plasmons in gold nanorods to overcome the low emission yield of carbon nanotubes. This simple, robust and flexible technique strongly enhances the luminescence of nanotubes, even for chiralities whose enhancement has never reported before.

We investigated the electron每electron interactions in monolayer graphene quantum capacitors by performing a simultaneous analysis of compressibility as function of temperature and carrier density. By considering the temperature-dependent charge fluctuations, we also established a model to explain the round-off effect near the Dirac point.
