A New 'Super Ice' Is 10 Times Stronger, Bringing It Close to The Strength of Concrete
Researchers have created a strengthened "BioPykrete" by combining ice with cellulose nanocrystals and a custom protein that binds the plant-based crystals to the ice structure. In small-scale tests, the material was about 10 times stronger than regular ice and absorbed 70 times more energy before breaking.

Scientists have developed a novel material known as BioPykrete, created by combining ice with cellulose nanocrystals and a specialized protein. In small-scale tests, the material proved to be around 10 times stronger than traditional ice and exhibited a remarkable ability to absorb 70 times more energy before breaking. The key to this strength lies in the cellulose nanocrystals, which act as microscopic reinforcing agents for the ice structure, effectively preventing cracks from spreading.
The protein used in this process, called CBM3a-AFPIII, serves a dual purpose. It's essentially a glue, binding the cellulose nanocrystals to the ice, and also functions as an antifreeze protein, ensuring the ice remains stable under various conditions. The researchers believe that by fine-tuning their ingredients and techniques, they can further enhance the strength of BioPykrete.
Moving forward, the team plans to conduct more extensive tests on the material's durability and investigate how cracks propagate through BioPykrete. This will help confirm the underlying strengthening mechanisms. Beyond its potential applications in packaging and construction, this innovative approach could pave the way for new materials capable of withstanding extreme environments. The study's findings have been published in the journal Colloids and Surfaces B: Biointerfaces.
