An ultrastrong and superhard conductive carbon composite has been synthesized, which consists of ultrafine nanodiamond homogeneously dispersed in disordered multilayer graphene with incoherent interfaces. The microstructures of the composite suggest that the transition from amorphous carbon to diamond involves the extensive nucleation and diffusion-driven growth of nanodiamond.
Three-dimensional printing of hydrogels loaded with fungal mycelium can produce living materials with unique adaptive properties in shapes that are relevant for engineering applications. The metabolic activity of the living mycelial network allows the printed structure to grow autonomously and self-regenerate when it is provided with nutrients in water.
