Nanoscience and nanotechnology

The new 3D nanofabrication method makes it possible to manufacture complex multi-layered solids all in one step. In this example, seen in these Scanning Electron Microscope images, a view from above (at top) shows alternating layers containing round holes and long bars. As seen from the side (lower image), the alternating shapes repeat through several layers.

A new way to build nanostructures

Combining top-down and bottom-up approaches, new low-cost method could be a boon to research with a variety of applications.

When compounds of bromine or chlorine (represented in blue) are introduced into a block of graphite (shown in green), the atoms find their way into the structure in between every third sheet, thus increasing the spacing between those sheets and making it easier to split them apart.

Layer upon layer

Method holds promise for making two- or three-tier graphene films that could be used for new electronic devices.
