Turning a new leaf : Complex, hierarchical structures of magnetic and conductive iron carbide (Fe 3 C) have been synthesized from a biological template. By dispersing aqueous metal precursors over the surface of a leaf skeleton, the intricate vascular structure is replicated in the ceramic product (see picture: Fe 3 C leaf structures attached to a magnet).
