Recently, the joint research group led by Peng Gao, Kaihui Liu (Peking University), and Yuyang Zhang from the University of Chinese Academy of Sciences employed transmission electron microscopy with electron energy loss spectroscopy and first-principles calculations, uncovered the twist-angle coupling effect in h-BN/graphene heterostructures.
Covalently bonded ceramics exhibit preeminent properties-including hardness, strength, chemical inertness, and resistance against heat and corrosion-yet their wider application is challenging because of their room-temperature brittleness.
