Back Cover: First, hexagonal boron nitride nanosheets functionalized with hydroxyl groups are prepared, and a schematic diagram of the molecular structure of BNNSs is shown in the cover design. As a special engineering plastic, polyether ether ketone (PEEK) is widely used in aerospace, automobile, highspeed rail industry, and 5G fields. In article number 2100532 by Yanhua Yang and co-workers, PEEK fiber is used to prepare high thermal conductivity composite materials with filler orientation structures. The picture shows that PEEK fibers are coated by BNNSs in the cover design. The diagram of the Tai Chi demonstrates it has broad and bright prospects for applications in a range of emerging electronic devices. The light in the background reflects the phonons are transmitted at high speed inside the composite.
