The material family of 2D carbide MXenes could one day be used in hypersonic thermal protection systems, but first researchers need to develop a reliable method for handling defects generated during the acidic synthesis process. Researchers at Purdue University found that alkali cations can be used to fill these defects and improve MXene phase stability.

There is ample evidence that nanoparticles can affect the healthy growth of a fetus, but the mechanisms involved are largely unknown. An interdisciplinary team led by Empa researchers showed that nanoparticles can cause indirect harm by disrupting the production of messenger substances in the placenta, leading to impaired blood vessel formation.

In July 2023, researchers announced the creation of high-strength, lightweight glass nanolattices by coating DNA origami scaffolds with silica. Their new open-access paper, published in January 2024, describes the functionalization of these glass-coated scaffolds by infiltrating the nanolattice with metal and metal oxide particles.
