New Entropic Routes for Nano‐Bands and Nano‐Particles

“…The sub-reactions shown below, especially when oscillatory (i.e., dissipative), offers a method of dispersing nano-particles and faulted regions in a manner similar to micro-particle and micro-band formation in lower temperature chemical reactions [7], We also compile evidence from the literature for the sub-reactions and BZ hypothesis from published synchrotron and fine-scale time-lapse XRD studies [24,26,27,32,46,60,61] for explosive micropyretic synthesis of NiAl and other compounds. A compilation of published data [24,25,41,47,[62][63][64][65] and new data on thermal oscillations also points to the BZ hypothesis [31,40,[66][67][68][69][70][71].
