摘要: Different carbon and ceramic nanostructures (nanotubes, nanowires, nanofibres, nanorods, nanoencapsulates) have great potential for improving our understanding of the fundamental concepts roles both dimensionality size on physical properties, as well many applications. Carbon nanotubes (CNTs) were produced in arc plasma using different starting carbons, anode material. Low-graphitized carbons (including black) proved to be much more efficient comparing regular graphite The optical emission absorption spectroscopy was used spectral diagnostics arc. also produce onions containing magnetic nanocrystallites (Fe alloys) core. process optimized procedure isolate encapsulates elaborated. nanocapsules Fe obtained via combustion synthesis from mixtures NaN3-C6Cl6-Ferrocene. This technique very silicon carbide nanowires Teflon (PTFE) reductants (CaSi2, Si). protocol efficiently purify final product (up 98 wt%) proposed.
