摘要: Although the formation of filamentous carbon requires a transition metal catalyst particle, gaseous environment containing carbon, and appropriate physical chemical conditions, such filaments are formed rather broadly in modern industrial processes [1]. Indeed, history their solar system may be more venerable than had previously been expected. Bradley, Brownlee, Fraundorf [2] have published transmission electron microscope image filament present chondritic meteorite. These researchers found several micrometeorites collected stratosphere which representative debris from planets were formed. filaments’ length quality inferior to those grown laboratory under optimum they contain magnetite crystals interior show clear evidence hollow core.
