Hydrogenated and oxygenated nano-crystalline boron-doped diamond (BDD) films were prepared by hydrogen-plasma treatment and boiling in the strong acids, respectively. Surface characteristics of the two diamond films have been investigated by scanning electron microscopy (SEM) and Raman spectroscopy. In order to clarify detailed electronic structures of surface-treated nano-crystalline diamond films,...
A facile approach to the surface oxidation of multi-walled carbon nanotubes (MWCNTs) is presented using oxidation solution to decorating MWCNTs, sonication to promote this effect and increase the population density of surface oxide groups. The sonication short time for MWCNTs oxidation /functionalization is desirable for minimizing structural damage to the MWCNTs that could lead to changes in their...
A novel room temperature synthesis of carbon nanotubes (CNTs) by liquid phase deposition of methanol is firstly reported. Nanotube samples were characterized with field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and Raman spectroscopy. FESEM micrographs revealed that nanotubes with diameter in the range of 20-200 nm were grown at room temperature. HR-TEM...
Nanojet means that the liquid is forced to pass through the nozzle with the nanosize diameter, we report here that nanojet was formed for the first time in lab by heating the PbO coated Pb clusters. In this experiment, the coated clusters are heated to more than 200 C and it was found that the inner Pb core melted and ran out from the cracked outer shell with a 200-nm-long(as long) trail. The in situ...
Nd3+ doped PbZr0.52Ti0.48O3 (PNZT) nanopowders were prepared by sol-gel methods in ethylene glycol system. Neodymium nitrate was used as Nd3+ source. The reaction mechanisms of nanopowder preparing process from the sol were discussed through using FTIR, XRD, TG-DTA, and it was proved that the heating temperature of PNZT was 50degC-100degC higher than PZT. PNZT lattice structure was characterized...
Two kinds of novel zinc/CNT composites were prepared by composite electrodeposition. The codeposition of carbon nanotubes and zinc was verified by the Raman spectrometry analysis. Scanning electron microscopy images illustrated the continuous and uniform zinc coverage on CNT, which were unique interfacial features in the currently known metal/CNT composites
This study produces low-temperature poly-silicon (LTPS) film by aluminum induced crystallization (AIC) method on Corning Eagle2000 glass substrate. Through the control of different sputtering power in depositing aluminum film, five kinds of specimens with sputtering power of 100, 200, 400, 800 and 1600 Watts, respectively, are made. Crystal quality, surface morphology, roughness and film residual...
