Determination of nano particle size is substantial since the nano particle size exerts a significant effect on various properties of nano materials. Accordingly, proposing non-destructive, accurate and rapid techniques for this aim is of high interest. There are some conventional techniques to investigate the morphology and grain size of nano particles such as scanning electron microscopy (SEM)...

The controllable preparation of nano-gold catalyst maintains a challenge. Except the parameters have been revealed before, here we'd like to show that controllable preparation of active nano-gold catalyst can be achieved using chlorine as an indicator. By tracing the chlorine concentration in the washing step, a series of Au/Fe2O3 catalysts were prepared with co-precipitation method. The applyi...

Preparation of micron and nano sized ammonium perchlorate (AP) particles in propellant formulation is required for access high burning rate propellants. The decomposition and burning rate of AP particles are mainly affected by decreasing the particle size, which can decrease the decomposition temperature, and increase burning rate.  AP particles at the micro and nano-scales, have a great influe...
