Physicists creates 'recipe book' for building new materials

By showing that tiny particles injected into a liquid crystal medium adhere to existing mathematical theorems, physicists at the University of Colorado Boulder have opened the door for the creation of a host of new materials with properties that do not exist in nature.

Graphene on nickel: Electrons behave like light

Scientists investigated the electronic properties of nickel coated with graphene and achieved an astonishing result. They could show that the conduction electrons of the graphene behave rather as light than as particles.

Researchers discover unexpected charge properties of single dopants

Researchers found that the precise location of the donor atom in the surface determined whether a positive or negative charge was induced in the surface, which was contrary to expectation because donors in bulk silicon are either neutral or positively charged, depending on sample temperature.

Could wood replace damaged bones?

Presently, finding biomimetic materials (the structure and function of biological systems), which are similar to bone in terms of strength, flexibility and density, is an ongoing concern for medical scientists. The hope is that it might be possible supplement metal alloy implants using such materials.

Molecular levers may make materials better

In a forced game of molecular tug-of war, some strings of atoms can act like a lever, accelerating reactions 1000 times faster than other molecules. The discovery suggests that scientists could use these molecular levers to drive chemical and mechanical reactivity among atoms and ultimately engineer more efficient materials.
