Artists and scientists alike find inspiration in nature. But two recent scientific studies found inspiration in the same creature: the mantis shrimp. The creature’s incredibly tough materials and complex eyes inspired innovations that could lead to fracture-resistant biocomposites and highly advanced optical sensors.

MXenes hold potential as additives in ultrahigh-temperature ceramics to improve mechanical properties—but a gap in understanding the phase stability and transformation of MXenes at high temperatures limits this application. Researchers at Indiana University–Purdue University Indianapolis investigated these properties in titanium carbide MXenes.

The 2D material borophene holds a lot of potential due to its flexibility, strength, and diverse atomic structure—but rapid oxidation of borophene in air makes application difficult. Researchers led by Northwestern University experimentally investigated the hydrogenation of borophene to see how well it stabilizes the material for practical use.

People who have color vision deficiency see colors differently from others. Tinted glasses and contact lenses offer a way to manage the condition, but to date only the former option is reliably effective. Researchers developed a new type of tinted contact lens using gold nanoparticles that shows potential for commercial scale-up.
