Activities in this TWA will advance the measurement of nano-particles (NP) populations such as metal nano-wires, single-walled carbon nanotubes, magnetic nano-particles, nanopowders and quantum dots. The focus of the TWA is standardization and cross-comparison of measurement techniques for determining the defining dimensional, electronic, chemical, optical or magnetic characteristics of the nano-particles.
Projects within the TWA may be defined for single classes of dispersed nano-particles. Activities have been initiated with a project on refining the measurement of chirality distribution in polydisperse single-walled carbon nanotube samples. Other characterizations of polydisperse nanoparticle populations, such as the measurement of titanium dioxide nano-powders, magnetic nanoparticles, or general measurements of particle size and dispersion state are also considered to be within the bounds of this TWA.
