As a significant equipment in power system, the operation condition of transformers directly determines the safety of power system. Therefore, it has been an indispensable measure to detect and analyze the dissolved gases in transformers, aiming to estimate the early potential faults in oil-insulated transformers. In this chapter, the adsorption processes between modified carbon nanotubes (CNTs) (CNTs-OH, Ni-CNTs) and dissolved gases in transformers oil including C 2 H 2 , C 2 H 4 , C 2 H 6 , CH 4 , CO, and H 2 have been simulated based on the first principle theory. Meanwhile, the density of states (DOS), adsorption energy, charge transfer amount, and adsorption distance of adsorption process between CNTs and dissolved gases were calculated. Moreover, two kinds of sensors, mixed acid-modified CNTs and NiCl 2 -modified CNTs, are prepared to conduct the dissolved gases response experiment. Then, the gas response mechanisms were investigated. Finally, the results between response experiment and theoretical calculation were compared, reflecting a good coherence with each other. The CNTs gas sensors possess a relatively high sensitivity and fine linearity, and could be employed in dissolved gas analysis equipment in transformer.

“…The mathematical dependence of qt versus t 1/2 is obtained if the process is considered to be influenced by diffusion in the particles and convective diffusion in the solution. According to the intra-particle diffusion model proposed by Weber and Morris [22], the root time dependence may be expressed by Equation (6).…”

KEYWORDSSilica-carbon nanoparticles (SCNP) were prepared from sonication of silica and anthracene. The size of homogenous nanoparticle is around 5-20 nm confirmed by Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). SEM analysis indicated surface porosity. SCNP were used to remove lead ions (Pb(II)) from aqueous solutions. Adsorption isotherm of Pb(II) on SCNP was well fitted in terms of the Freundlich and Langmuir models. The maximum adsorption capacity of SCNP for Pb(II) was found to be 385 mg/g (1.86 mmol/g) in batch experiment. Thermodynamic studies indicated that sorption process of lead onto SCNP was spontaneous and exothermic. A pseudo-second order model has been employed in order to describe the kinetic adsorption processes, and the thermodynamic activation parameters were calculated. In a column studies, qy the Yan adsorption capacity of SCNP for Pb(II) was found to be 130.66 mg/g (0.63 mmol/g).

“…When solar energy is focused (flux 500 -1000 W/cm2 and the temperature reaches 2800 -3000° C) on a carbon-metal target in an inert atmosphere, SWNTs and MWNTs can be produced [12][13][14]. It is also possible to use solar energy in a pyrolytic processes to produce MWNTs, particularly, the catalytic decomposition of CH 4 and C 4 H 10 in the presence of Ni/Al 2 O 3 or Co/MgO [15].…”

The first publication on the Buckminsterfullerene carbon molecule (C60) was in 1985 by Kroto et al. [1]. Not much else happened right after that since samples of C60 were not available for further study. It was the discovery of Krätschmer and Huffman's group [2] in 1990 that really opened up the field. They found a method to produce C60 in gram quantity. This made it possible for researchers around the world to investigate C60 properties and further advanced the field of nanocarbon research. Establishing the existence of a third crystalline form of carbon is one of the most exciting fundamental discoveries in science to date.
