Carbon nanotubes (CNTs) were first discovered by Iijima in 1991 [1]. CNTs have sparked great interest in many scientific fields such as physics, chemistry, and electrical engineering [2, 3]. CNTs are composed of graphene sheets rolled into closed concentric cylinders with diameter of the order of nanometers and length of micrometers. CNTs are in two kinds, based on number of walls, the single-w...

Arc discharge is one of the most efficient and environmental friendly method to synthesize Single Wall Carbon Nanotube (SWCNT). However, due to the ultra-fast synthesis procedure, localization of the SWCNT synthesis in an arc discharge plasma volume in situ has been a long standing problem. This relates to the ability of controlling volumetric synthesis of nanostructures in plasmas in general. ...

following our interest in reaching for a molded rubber article with possible detergent contact applications, durable silver nanopowder (agnp) is synthesized by arc discharge, then mixed with varying ratios of ethylene propylene rubber (epr), affording novel agnp@epr nanocomposites. x-ray diffraction (xrd) patterns of agnp as well as agnp@epr show no trace of impurity, while scanning electron mi...

Abstract. Since electromagnetic (EM) noise resulting from an arc discharge disturbs other electric devices, parameters on electromagnetic compatibility, as well as lifetime and reliability, are important properties for electrical contacts. To clarify the characteristics and the mechanism of the generation of the EM noise, the current noise up to GHz band frequency generated by slowly breaking c...

This work was focused on the studies of gliding arc plasma discharge with respect to its use in decomposition of volatile organic compounds and on the solid phase microextraction analysis of the discharge products. The simple one stage gliding arc reactor was used for these experiments. The applied voltage generating the discharge was varied in the range of 3.5 – 4 kV, the dry air and its mixtu...

Submarine volcanism represents ~80% of the volcanic activity on Earth and is an important source of mantle-derived gases. These gases are of basic importance for the comprehension of mantle characteristics in areas where subaerial volcanism is missing or strongly modified by the presence of crustal/atmospheric components. Though, the study of submarine volcanism remains a challenge due to their...
