For comprehensive utilization of CO contained in closed carbide furnace tail gas, the purification of HCN in the artificial tail gas mixed with pure gases was studied by means of adsorption using modified activated carbon. In range of this study the optimum conditions for preparing modified activated carbon are: NaOH concentration is 10 wt% and sulfonated cobalt phthalocyanine (CoPcS) concentration...
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...
Multi-wall carbon nanotubes (MWCNTs) were grown by spray pyrolysis of acetylene as the carbon source in the presence of Au-Co as catalyst precursors. A high yield of network-shaped carbon nanotubes (CNTs) with further purification has been obtained in the optimal conditions. The optimum synthesis parameters included a synthesis temperature of 700degC, growth time of 30 min, and a flow rate of acetylene...
Summary form only given. Amorphous carbon or diamond-like carbon (DLC) films have attracted much attention recently due to their good biocompatibility and have been proposed for use in blood contacting medical devices. The behavior of cultured cells is a good indicator of the surface biocompatibility and biological responses. In this study, amorphous hydrogenated carbon films were produced and a series...
As IC performance increases, many technical challenges appear in the areas of power delivery, thermal management, I/O density, and thermal-mechanical reliability. To address these problems, the use of aligned carbon nanotubes (CNTs) is proposed in IC packaging as electrical interconnect and thermal interface materials. The superior electrical, thermal, and mechanical properties of CNTs promise to...
