New York University Abu Dhabi completes research study to develop innovative impact-resistant materials

A new study by researchers at New York University Abu Dhabi has revealed promising prospects for developing advanced impact-resistant materials by analyzing the unique structure of the yarrow nut, the hard seed of a tree that grows in Western Australia and is distinguished by its exceptional ability to withstand harsh conditions.

This discovery highlights the growing role of nature as a source of inspiration for engineering innovation. The research team found that the secret behind the walnut's toughness lies not only in its strength but also in its multi-layered internal design, which combines a very hard outer shell with a softer, more flexible inner layer. This unique structure allows the walnut to absorb and distribute shock energy in a balanced way, preventing cracks from forming or spreading.

These results are an important step towards developing new synthetic materials based on similar principles, as this natural model can be employed in designing lightweight and highly efficient shock-absorbing components, thereby enhancing safety in multiple applications, including protective equipment.

Wujud Awad, a postdoctoral research fellow at New York University Abu Dhabi, explained that what distinguishes the walnut tree is its ability to combine strength and flexibility within a single structure, noting that this delicate balance offers valuable scientific insights for developing materials capable of absorbing shocks more effectively without being damaged.

For his part, Panchi Nomov, professor of chemistry at New York University Abu Dhabi and leader of the research team, confirmed that nature provides advanced models for understanding the concept of strength, explaining that the walnut does not rely solely on rigidity, but on a smart structure that controls how the shock energy is transferred and directs the cracks in a thoughtful way, rather than spreading randomly.

This study was conducted over five years at the Smart Materials Laboratory of the Center for Smart Engineering Materials at the university, where researchers used advanced 3D imaging techniques along with precise mechanical tests to analyze the nut's response to pressure.

Based on these results, the research team succeeded in developing a material inspired by this bio-design, paving the way for a new generation of engineering materials that combine lightweight construction with high impact resistance.

This research, which was published in the Global Advanced Science Journal, was conducted with the support of the Research Institute at New York University Abu Dhabi, as part of its efforts to push the boundaries of scientific knowledge and develop practical applications that serve various vital sectors.
