The inside backcover picture shows a novel microcapsule with an organic‐inorganic nanocomposite shell which was designed and applied as a functional additive for modifying high energy propellants to reduce their erosion performance. As the addition of nanocomposites reached the maximum values of 5.1 %, the erosivity of modified propellant reduced by 37.0 %. The plausible anti‐erosion mechanisms for this microcapsule could be: the microcapsule with high heat absorption property could produce a lower flame temperature, and the nanoparticles deriving from microcapsule surface can be deposited on the erosion tube surface and formed a thermal‐protective coating. More details can be found in the Full Paper by N. Sun and Z. Xiao on page 1252 ff.
