Scanning electron microscopy images of the starting material (from left), the material resulting from the high-concentration phosphoric acid treatment and the purified boron nitride nanotubes.

The key to understanding how a material will respond to specific conditions is a complete analysis of its properties. As well as the compositional and structural information offered by FIB-SEM and SEM ...

When preparing cross sections, the standard procedure using the FIB-SEM technique is the use of high currents to quickly remove material, then lower the FIB current for an improved beam profile and ...
