Random close packing or jamming of spheres in a container

Scientists at the theoretical institutes, Chinese Academy of Science and Cybermedia Center at Osaka University performed extensive computer simulations to generate and examine random packing of spheres. They show that the ...

Innovative method enables new view into Earth's interior

An innovative X-ray method enables new high-pressure investigations of samples under deep mantle conditions. The technique, which was developed by a team led by Georg Spiekermann from DESY, the German Research Centre for ...

General principles to explain DNA brick self-assembly

(Phys.org)—DNA bricks are an odd phenomenon. They are nanostructures built from synthetic, single-strand DNA that self-assemble into 3D structures. Several years ago, researchers at Wyss Institute at Harvard demonstrated ...

Fullerene chemistry with silicon

Goethe University chemists have managed to synthesise a compound featuring an Si20 dodecahedron. The Platonic solid, which was published in the Angewandte Chemie journal, is not just aesthetically pleasing, it also opens ...

Opening a wide window on the nano-world of surface catalysis

(Phys.org) —Surface catalysts are notoriously difficult to study mechanistically, but scientists at the University of South Carolina and Rice University have shown how to get real-time reaction information from Ag nanocatalysts ...

Carbon dioxide study adds to picture of global carbon cycle

(Phys.org) —One of the most widely known compounds on Earth is carbon dioxide, or CO2. We learn as children that CO2 is a key component of photosynthesis, the process by which plants, algae, and bacteria convert light into ...
