Porous Silicon (PS) is one of the established materials and can be used in variety of applications in its different forms. Use of monolayer PS film for synthesis of Si QDs is reported here. Nanometer-sized silicon particles are produced by ultrasonic dispersion of thin films in DI water. PS films are characterized using cross sectional scanning electron microscopy and gravimetric analysis while the...
Ball milling is an effective way of producing defective and nanostructured graphite. In this work, graphite was milled under 3 bar hydrogen in a tungsten carbide milling pot, and the effect of milling conditions on the microstructure and hydrogen storage properties was investigated by TGA-Mass Spectrometry, XRD, SEM and Raman spectroscopy. After milling for 10 hours, 5.5 wt% hydrogen was released...
In this work, a simple, efficient and cost-effective in situ purification method has been developed based on gas-phase oxidation, in an effort to increase purity of single-walled carbon nanotubes (SWNT) in the course of SWNT synthesis by induction thermal plasmas. This newly developed purification method has the following advantages compared with the conventional off-line gas-phase oxidation techniques;...
The effect of thermal annealing on the field emission properties of double-walled carbon nanotubes (DWCNT) grown by chemical vapour deposition is studied. The properties of the DWCNTs were examined using SEM, TEM, Raman and TGA analysis. It was found that high-temperature annealing enhances the field emission performance of DWCNTs
