Research team models new atomic structures of gold nanoparticle

They may deal in gold, atomic staples and electron volts rather than cement, support beams and kilowatt-hours, but chemists have drafted new nanoscale blueprints for low-energy structures capable of housing pharmaceuticals ...

Observing the random diffusion of missing atoms in graphene

Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging non-repeating atomic arrangements ...

Local icosahedral order in metallic glasses

(Phys.org) —Metallic glasses are essentially a frozen, supercooled liquid. They are amorphous metals, often alloys, which are non-crystalline and therefore have a highly disordered atomic arrangement. They are true glasses ...

Cerium's unusual behaviour

(PhysOrg.com) -- Livermore researchers have found that a crystal of cerium -- the chemical element that can be used for catalysts and fuel additives -- behaves in very unique ways when subjected to high pressures.
