Paper, Fracture-resistant cement inspired by the spines of sea urchins
A group of German researchers had developed a new type of cement inspired by the nanostructure of sea urchin spines. These spines are incredibly durable due to the crystalline blocks of calcite are covered by a layer of calcium carbonate. This layer serves as a dampening defense to an impact force. The team managed to translate this principle into cement using a negatively charged peptide combination to adhere to the cement allowing for a brick-and-motor effect to be replicated within the cement.
