“…Currently, there are several competing methods for obtaining nanosized carbon (electric arc graphite spraying [27], laser evaporation of graphite [28], chemical deposition from vapor [29], etc.). We have proposed a relatively simple method for producing nanoparticles, the main advantage of which is its low cost (raw material is ethanol, medium electricity consumption) and high speed (2 L of colloid per minute from one plant).…”

An electrospark technology has been developed for obtaining a colloidal solution containing nanosized amorphous carbon. The advantages of the technology are its low cost and high performance. The colloidal solution of nanosized carbon is highly stable. The coatings on its basis are nanostructured. They are characterized by high adhesion and hydrophobicity. It was found that the propagation of microorganisms on nanosized carbon coatings is significantly hindered. At the same time, eukaryotic animal cells grow and develop on nanosized carbon coatings, as well as on the nitinol medical alloy. The use of a colloidal solution as available, cheap and non-toxic nanomaterial for the creation of antibacterial coatings to prevent biofilm formation seems to be very promising for modern medicine, pharmaceutical and food industries.

The diesel engines are energy efficient, but their particulate (soot) emissions are responsible of severe environmentaland health problems. This review provides a survey on published information regarding dieselsoot emission, its adverse effects on the human health, environment, vegetations, climate, etc. The legislationsto limit diesel emissions and ways to minimize soot emission are also summarized. Soot particles aresuspected to the development of cancer; cardiovascular and respiratory health effects; pollution of air, water,and soil; impact agriculture productivity, soiling of buildings; reductions in visibility; and global climatechange. The review covers important recent developments on technologies for control of particulate matter(PM); diesel particulate filters (DPFs), summarizing new filter and catalyst materials and DPM measurement.DPF technology is in a state of optimization and cost reduction. New DPF regeneration strategies(active, passive and plasma-assisted regenerations) as well as the new learning on the fundamentals ofsoot/catalyst interaction are described. Recent developments in diesel oxidation catalysts (DOC) are alsosummarized showing potential issues with advanced combustion strategies, important interactions on NO2formation, and new formulations for durability. Finally, systematic compilation of the concerned newer literatureon catalytic oxidation of soot in a well conceivable tabular form is given. A total of 156 referencesare cited. ©2010 BCREC UNDIP.

“…Therefore, the investigation of catalyst including its type, composition, and content is very important to control the synthesis of SWCNTs on large scale. Generally, SWCNTs are prepared by using catalysts which include transition single metal or multimetals, such as Fe, Co, and Ni or Co/Ni and Ni/Y [11][12][13][14]. All the catalysts are effective to improve the production of SWCNTs under certain conditions.…”

Single-walled carbon nanotubes (SWCNTs) were prepared by a modified arc discharging furnace using Fe-Ni-Mg powders as catalyst at600∘C. The effects of catalyst composition and content on the production rate and purity of SWCNTs are investigated in this paper. When the Fe-Ni-Mg catalyst composition is 2: 1: 2wt%and the catalyst content is 5wt%, the experimental results indicate that the production of SWCNTs is 12 grams per hour, and the purity and diameter of SWCNTs are70%and 1.22∼1.38 nm, respectively. The results indicate that the cooperative function of catalyst composition and content plays an important role in the production of SWCNTs. The aim of this work is to control the production process of SWCNTs efficiently.
