Analytical techniques for particle size distribution and wettability of the powder
In the particle size distribution measurement of the powder, it is necessary to select an optimal measurement method matching to the range of the particle size and particle size distribution. Dispersibility of the powder depends on the interaction energy between the solvent and the particles (wettability, etc.). Wettability can be estimated from the heat of immersion obtained by micro-calorimeter .

Nanoscale Raman analysis of carbon materials using AFM-Raman microscopy
AFM-Raman microscopy is a method which allows for both topographic and Raman imaging with nanometer resolution. Here its excellent resolving power on nanoscale structural analysis on carbon materials, e.g. carbon nanotubes and graphene oxides, is demonstrated using highly-stable ‘next generation’ AFM-Raman probes.
