Israeli Researchers Develop "Super-Ice" 10 Times Stronger Than Regular Ice

Researchers at the Hebrew University of Jerusalem have engineered a novel material, dubbed BioPykrete, that is ten times stronger than regular ice and can absorb seventy times more energy before breaking. This breakthrough, led by Professor Ido Braslavsky of the Faculty of Agriculture, Food and Environment, addresses ice's primary weakness: its tendency to fracture and shatter rapidly. BioPykrete incorporates plant-derived nanocellulose crystals, which form a three-dimensional network within the ice during freezing. Additionally, an engineered protein acts as a molecular "glue," binding the ice crystals to the nanocellulose. This structure effectively halts the propagation of cracks, redirecting them and preventing catastrophic failure. The addition of this engineered protein doubled the material's strength and energy absorption capacity compared to a simple ice and nanocellulose mixture. Professor Braslavsky explained that the goal was to control the molecular-level interactions, resulting in a material that not only strengthens ice but also alters its fracture behavior, allowing it to deform gradually rather than shatter suddenly. This innovation could have significant implications for green construction and infrastructure in extremely cold regions, offering a sustainable and environmentally friendly alternative to traditional materials like concrete and steel, which are expensive and carbon-intensive to transport to Arctic and Antarctic areas. While this represents an initial proof of concept, further research will investigate the material's long-term stability, its response to freeze-thaw cycles, and potential enhancements through new freezing methods and additional proteins.
