This schematic drawing shows the apparatus, with the cryogenic ion trap shown in the inset, used to predict the behavior of ions more accurately.
New approach to studying ions accurately predicts behavior, providing insights for biological systems, environmental processes, materials development.
On the left, a computer model depicts a self-assembled tetrahelix made up of tetrahedral quantum dots. On the right, a skeleton view of the tetrahelix demonstrates the chiral structure of the assembly.
Scientists image complex superstructures self-assembled from tetrahedral quantum dots, expanding our understanding of forming small, complex crystals.
In a novel simultaneous clean-and-repair mechanism, flowing oil-in-water droplets move nanoparticle (NP) debris, shown as green spheres, into the cracks. The droplets pick up the NPs, then deposit them in the cracked regions.
Simple fluid-driven nanoparticle catch-and-release process directs repair of cracks with debris from the damage.
