Field emission from iron-filled carbon nanotubes observed in-situ in the scanning electron microscope

Acrylate/carbon nanotubes nanocomposites were prepared using sol-gel method. Carbon nanotubes with different percentage (0.2%, 0.4%, 0.6%, 0.8% and 1.0%) incorporated into acrylate and deposited on mild steel. Surface of acrylate/carbon nanotubes composites were characterized using by field emission scanning electron microscope (FESEM). Carbon nanotubes uniformly distributed in acrylate observed by FESEM shows increase in percentage of carbon nanotubes blend with acrylate the peak distribution become decreases.

AbstractWe report recent development of a three-probe micromachined nanomanipulator for manipulation and in-situ characterization of nanomaterials in scanning electron microscope (SEM). The nanomanipulator consists of three independent probes having thermal bimetallic actuators and nanoscopic end-effectors. Nanoscale end-effectors with sub-100-nm spacing are created using focused ion beam (FIB) milling to directly interface with nanoscopic objects (e.g., nanotubes, nanowires). Handling of individual carbon nanotubes (CNTs) was successfully realized with the nanomanipulator in an SEM.

An in situ thermal oxidation strategy was proposed for synthesizing different SnO2 nanostructures, using our homemade SnS2 nanoplates as a precursor. The characterization results from X-ray diffraction, energy dispersive X-ray spectroscopy, and field emission scanning electron microscope revealed that the heating temperature played an important role in the microstructure and composition of the resultant products. By heating the SnS2 nanoplates in air at 400, 600 and 800 °C for 5 h, nanoplates, a mixture of nanoplates and nanoparticles, and nanoparticles of SnO2 were synthesized, respectively. The residual S was about 2.2 mol % in the product synthesized at 400 °C, while no residual S was detected in the products synthesized at 600 and 800 °C.
