Abstract

Outside back cover image: Advanced light-element inorganic foams, such as graphene or boron nitride foams, have the ability to deliver the outstanding nano-scaled properties upon the macroscopic foam bulks. Their 3D network structure can avoid the severe agglomeration and the weak interconnection between building blocks in previous powder state. Consequently, such 3D network confers large surface area and excellent mechanical, thermal, and electrical characteristics. These graphene or boron nitride foams are utilized in smart multi-functional applications such as supporters, elastomers, acoustic and electromagnetic shields or absorbers, thermal management, adsorbents, electro- and thermo-catalysts, and battery electrodes.
