چکیده

The functionalization and defect formation of SWNTs caused by isotropic plasma treatments were studied using oxygen desorption/adsorption kinetics by measuring the time dependence of the in situ thermoelectric power (TEP). It is shown that the plasma treatments result in the formation of low binding energy sites for oxygen adsorption. Raman and x-ray photoelectron spectroscopy (XPS) data are in good agreement with the results.

Is the intrinsic thermoelectric power of carbon nanotubes positive?

The thermoelectric power (TEP) of single-walled carbon nanotubes (SWNTs) is extremely sensitive to gas exposure history. Samples exposed to air or oxygen have an always positive TEP, suggestive of holelike carriers. However, at fixed temperature the TEP crosses zero and becomes progressively more negative as the SWNTs are stripped of oxygen. The time constant for oxygen adsorption/desorption is...

Kinetic study of CO desorption from cathodic electrochemically treated carbon paper supported Pt electrodes

Platinum particles were grown directly by an electrodeposition process on electrochemically treated carbon paper (CP) for kinetic study of carbon monoxide (CO) desorption. The treatment on CP was performed by applying −2 V for cathodic oxidation over 5 min. Treated CP was characterized by FTIR to investigate the oxygen groups on its surface. CO surface coverage at each temperature was determine...

Study of the Enhanced Precipitation of an Aluminium 6061 Alloy Reinforced by SiC Particles in the Range of β\" Phase Temperature (RESEARCH NOTE)

An experimental method to follow the evolution of the precipitation phenomena in the metal-matrix composites using the thermoelectric power measurements is described. It is shown that one can follow the kinetics of the precipitation during aging. The influence of the reinforcement on the precipitation kinetics is studied in case of an aluminum 6061- SiC, composite (where SiC, represents SiC par...

 Polycrystalline samples of NdBa2-xLaxCu3O7-δ with x=0, 0.05, 0.10, 0.15, 0.20, and 0.30 were made by standard solid state methods. The transport and superconducting properties have been studied by the resistivity measurements as a function of temperature and doping concentration. In order to measurements the hole concentration in CuO2 planes, the room temperature thermoelectric power was measu...
