Nanostructures feel the chill
TEM image of cerium oxide nanorod formed in an ice channel
EMSL researchers and their collaborators, the University of Central Florida, Pacific Northwest National Laboratory, and Defence Academy of the United Kingdom, have tested a new way to build nanostructures that is ‘green’ and simple.
Researchers grew cerium oxide nanostructures inside the tiny voids that form in aqueous solutions on freezing. By controlling the solution freezing rate, nanoparticle concentration and storage temperature, the team’s ice mould method may be used to produce nanostructures with tailored shapes and sizes suitable for a variety of applications – from biology to electronics.

Researchers have moved closer to being able to develop miniscule structures with application potential in sophisticated sensors, catalysis, and nanoelectronics.
Dr Manfred Buck and his team of researchers at St Andrews University, have developed a way of forming an easily modified network of molecules over a large area – the chemical technique provides an advantageous alternative to traditional methods which become increasingly cumbersome at the ultra small length scale.
The key to the development lies in the creation of robust and versatile surface – self-assembling structures just one molecule thick which can be exploited for further control and manipulation of nanostructures.
