This article presents the results of comprehensive study on the structure and morphology of iron nanopowders synthesized by electric explosive evaporation of metal wire. The results of scanning and transmission electron microscopy showed that nanoclusters have a spherical shape with an average diameter of 65 nm. It was revealed based on the analysis of the diffraction patterns that nanoparticles of nanopowders obtained in electric explosion have a crystal lattice with a parameter less than a standard cell. The results of computer experiments are in good agreement with the findings of X-ray analysis. However, the question about the reasons of distortion of the crystal lattice of nanoclusters remains controversial.

В работе описаны результаты экспериментов по получению углеродных наноструктур методом химического осаждения из газовой фазы на поверхности медных пластин. В ходе проведённых экспериментов было изучено влияние температуры на структурообразование осаждаемых образцов. При температурах 500 °С, 550 °С и 600 °С наблюдался рост углеродных наноструктур. Анализ методами комбинационного рассеяния света и сканирующей электронной микроскопии показал, что при оптимальных параметрах серии экспериментов происходит синтез углеродных наноструктур. Углеродные нановолокна обладают различными диаметрами в диапазоне 50-200 нм и имеют различную морфологию от спиралевидных до разветвлённых и прямых. Медные кластеры располагаются на концах углеродных нановолокон, а также внутри. Спектроскопия комбинационного рассеяния света определила по отношению интенсивностей групп, таких как D и G, что синтезированные углеродные нановолокна обладают хорошей степенью упорядоченности и графитизации.

The article presents the results of experiments on the synthesis of carbon nanofibers by thermal chemical vapor deposition using copper nanopowders obtained by electric explosion of wire as catalysts. Stable growth of carbon nanofibers was carried out at temperatures significantly lower than normally used. The process parameters that are optimal for low-temperature growth of carbon nanofibers have been identified during the performed experiments. The synthesized samples have different diameters and morphology (from spiral to direct). Copper clusters are both at the ends and inside the fibers. The results of IR spectroscopy indicate that the structure of the obtained carbon nanofibers is polymeric. X-ray analysis revealed the presence of a halo on the diffraction patterns at small values of the angle 2θ, which proves that the grown structures have an amorphous nature. There are no groups that are responsible for long-range order in all Raman spectra. Studies by transmission electron microscopy showed that nanostructures do not have an internal channel and nanofibers are solid.
