The cover picture shows a novel micro‐nano ferric perfluoroocate [Fe(PFO) 3 ] as an unusual catalyst multifaceted effects on AP/Al/HTPB composite solid propellant. Our study shows that Fe(PFO) 3 could improve the burning rate of the propellant as well as suppress the combustion agglomeration process. Fe(PFO) 3 could also decrease the thermal decomposition temperature of Al/AP/HTPB composite solid propellant and the heat release. Impressively, The decomposition products of Fe(PFO) 3 were proved to trigger the thermite reaction with Al at 635 °C leading to large heat release and formation of α‐Al 2 O 3 . Details are discussed in the article by Fei Zhen et al. on page 362 ff.
