Transition from five-fold symmetric to twinned fcc gold particles by thermally induced growth

Research was conducted to examine the transition from five-fold symmetric to twinned FCC gold particles by thermally induced growth. The objective is to study the details of any structural rearrangement that may arise during thermal treatment of highly dispersed metal particles in a preceramic inorganic matrix using in situ X-ray diffraction method. Results indicate that accurate X-ray data and simulations using the Debye functions can provide valuable insight into the complex process of crystal growth for nanocrystals.
