Exciting change is on the way! Please join us at nsf.gov for the latest news on NSF-funded research. While the NSF Science360 page and daily newsletter have now been retired, there’s much happening at nsf.gov. You’ll find current research news on the homepage and much more to explore throughout the site. Best of all, we’ve begun to build a brand-new website that will bring together news, social media, multimedia and more in a way that offers visitors a rich, rewarding, user-friendly experience.

Want to continue to receive email updates on the latest NSF research news and multimedia content? On September 23rd we’ll begin sending those updates via GovDelivery. If you’d prefer not to receive them, please unsubscribe now from Science360 News and your email address will not be moved into the new system.

Thanks so much for being part of the NSF Science360 News Service community. We hope you’ll stay with us during this transition so that we can continue to share the many ways NSF-funded research is advancing knowledge that transforms our future.

New nanoparticle superstructures made from pyramid-shaped building blocks

National Science Foundation-funded researchers have assembled complex macroscale superstructures from pyramid-shaped nanoparticle building blocks. The research demonstrates a promising new way to bring the useful properties of nanoparticles to macroscale materials and devices. The research group developed the building blocks used in the study a year ago. The particles are quantum dots -- nanoscale semiconductors that can absorb and emit light. Their tetrahedral shape has important advantages over spheres when using them to build larger structures. Tetrahedra can pack together with less void space than spheres, making structures potentially more robust. In addition, the particles used in the study are anisotropic, meaning they have different properties depending upon their orientation relative to each other. Spheres, on the other hand, are the same in every direction.
