Field emission scanning electron microscopes studies

Are carbynes produced in laboratory carbon and C IC Ar vapors designed to simulate the properties carbon dust in astrophysical environments Field-emission scanning electron microscope (FESEM) and HRTEM studies of vapor-condensed carbon smokes showed a wide range of carbon morphologies that were free of metal impurities (at EDS detection limits), viz. 1. Ceo and higher fullerenes that agglomerated into amorphous soot grains, 2. fullerenic nanotubes and onions, 3. amorphous carbon sheets,...

TEM observations were performed in the as-received and deformed samples in order to reveal the effects of microstructure on the fatigue response of the studied alloy. Fracture surfaces of the deformed fatigue test specimens were comprehensively examined in a scanning electron microscope (JEOL JSM6500F) equipped with field emission gun to determine the macroscopic fracture mode and characterize the fine-scale topography and microscopic mechanisms governing fatigue fracture. 

Field Emission Scanning Elecfron Microscopy (FE-SEM) was performed in order to study the product morphologies of the samples. The aforementioned silica samples, which were suspended in water, were centrifuged (r. p. m. = 13400) and washed with ethanol. They were then placed on SEM sample holders and dried. The dried silica samples were sputter coated with gold and were then analyzed under the electron microscope. 

Samples with grooves obtained from multiple scratch testings were coated with gold. The sample surfaces were then studied using field emission gun scanning electronic microscope (FEG-SEM).
