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 ...

Imaging electron pairing in a simple magnetic superconductor

In the search for understanding how some magnetic materials can be transformed to carry electric current with no energy loss, scientists at the U.S. Department of Energy's Brookhaven National Laboratory, Cornell University, ...

Solving mysteries of metallic glass at the nanoscale

The matter of how metals deform or respond to external stresses has been extensively studied among metallurgists for centuries. When it comes to conventional metals—the crystalline kind with atoms that line up in neat patterns—the ...

New strategy to effectively prevent component failures in metals

When a metal is stressed far below its yield strength at elevated temperatures, a process known as creep can occur. Creep, the time-dependent deformation of materials, is responsible for a great number of component failures ...

Making plastic durable and degradable

Polyethylene is the most abundantly manufactured plastic in the world. Due to properties like durability, it has many diverse, and even long-term uses. Professor Stefan Mecking's team in the Department of Chemistry at the ...
