 | Scientists in Australia are the first to etch structures less than a hundred nanometres in size on the inclined surfaces of diamond by simply using a variable pressure scanning electron microscope (SEM). They believe their electron beam induced etching (EBIE) could make nanofabrication of diamond devices accessible to every nanotechnology laboratory in the world. |  |
 | Controlled fabrication of semiconductor nanostructures is an essential step in engineering of high performance photonic and optoelectronic devices. Diamond has recently attracted considerable attention as a promising platform for quantum technologies, photonics and high resolution sensing applications. |  |

 | Carbon nanotubes have the potential to be a wonder technology: their properties include a thermal conductivity higher than diamond. |  |
