The secret behind crystals that shrink when heated

Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have new experimental evidence and a predictive theory that solves a long-standing materials science mystery: why certain crystalline materials ...

1 + 1 does not equal 2 for graphene-like 2-D materials

Physicists from the University of Sheffield have discovered that when two atomically thin graphene-like materials are placed on top of each other their properties change, and a material with novel hybrid properties emerges, ...

Nanoribbons in solutions mimic nature

Graphene nanoribbons (GNRs) bend and twist easily in solution, making them adaptable for biological uses like DNA analysis, drug delivery and biomimetic applications, according to scientists at Rice University.

Measuring the magnetization of wandering spins

The swirling field of a magnet—rendered visible by a sprinkling of iron filings—emerges from the microscopic behavior of atoms and their electrons. In permanent magnets, neighboring atoms align and lock into place to ...

Switchable material could enable new memory chips

Two MIT researchers have developed a thin-film material whose phase and electrical properties can be switched between metallic and semiconducting simply by applying a small voltage. The material then stays in its new configuration ...

Symmetry matters in graphene growth

What lies beneath growing islands of graphene is important to its properties, according to a new study led by Rice University.
