Optically active defects improve carbon nanotubes

The properties of carbon-based nanomaterials can be altered and engineered through the deliberate introduction of certain structural "imperfections" or defects. The challenge, however, is to control the number and type of ...

Discovery could lengthen lifespan of electronic devices

Nobel laureate Herbert Kroemer once famously asserted "The interface is the device." The observations by the Sydney researchers could therefore spark a new debate on whether interfaces—which are physical boundaries separating ...

Balancing between build-up and break-down of bone

Despite what some people think, bone is not merely a passive component of the body. The skeleton is structurally dynamic and responds to life's physical stresses with continual equilibration between bone mass loss and reformation. ...

The spintronics technology revolution could be just a hopfion away

A decade ago, the discovery of quasiparticles called magnetic skyrmions provided important new clues into how microscopic spin textures will enable spintronics, a new class of electronics that use the orientation of an electron's ...

Molecule could beat antibiotic-resistant infections

By using their knowledge of how bacteria co-exist and compete with one another in nature, Western University researchers have discovered a compound that can inhibit the growth of Staphylococcus aureus, a deadly bacterium ...

Nanoparticles reveal their location via mirror SELFI

Can a mirror turn an orange into a doughnut? The answer is definitely no in the real (macro) world. But at the nanoscale, a mirror can turn an 'orange' shaped pattern into a 'doughnut' shaped pattern by overlapping the 'orange' ...
