The rational design of materials by organization at the atomic scale is attractive for delivering increased functionality, but there are practical difficulties in such precise construction. Nanocasting is an emerging technique that provides one way of solving the problem.
Knowing the temperature rise in shear bands with high spatial and temporal resolution is important for the development of materials with improved mechanical properties.
Systems in optoelectronics, (bio)sensors and actuators rely on the integration of heterogeneous components. Such integration will be aided by a simple technique — based on soft adhesion to an elastomeric stamp — for transferring microscopic objects to a wide range of surfaces.
Computing with molecules as building blocks for circuits is an exciting concept. To make it a reality, we need to understand all effects: both within the molecule and at the interfaces between molecule and contacts.
Electron microscopy reveals ordered layering imposed on liquid aluminium at the interface with a solid. A better understanding of this effect will have important consequences for applications ranging from fluid flow to casting.
