A THERMAL ANALYSIS METHOD FOR NANOPARTICLES

Analytica Chimica Acta, 2007
# For a small particle, probably it is more accurate, if we measure VOLUME of the particles, rather than WEIGHT, like a typical method: TG-DTA…液相中ナノ粒子のための熱分析法…..耐熱性を調べるには、粒子の重さより粒子の体積を計測。

NOVEL HEATING TECHNIQUES FOR PARTICLES & NANOMATERIALS
J. Am. Ceram. Soc, 2007
# Adding a (combustion type) shock-wave having hot gas fluctuating flow, into the cloud of sprayed aerosols/droplets enhanced the energy transfer during solvent evaporation and precipitation (then plus: crystallization and thermal decompostion). This route can also provide smaller particles than the predicted ones.
