Supramolecular engineering using self-assembly aims to develop complex functional materials and devices. The fabrication of acentric organic films by physical vapour deposition for electro-optic applications illustrates the potential of such bio-inspired approaches.
The spreading of metallic liquid drops on flat solid metal or ceramic substrates ranges from milliseconds — comparable to room-temperature spreading of water on glass — to hours. This varying timescale can be understood by what happens — or doesn't happen — at the foot of the drop where the...
Magnetic random-access memory (MRAM) has been touted as a universal memory with a wide range of potential applications in portable computers, consumer electronics and wireless devices. The use of certain combinations of materials that can now be deposited as thin-film layers with excellent...
Iron oxide-doped photonic crystals are a simple means to wrap fluid droplets and control their movement. But they are also clever because they can be 'bar-coded' and have in-built sensing capabilities, which makes them exceptional candidates for microfluidic devices.
Materials that exhibit both ferromagnetism and ferroelectricity could be useful, but they are unfortunately very rare. Could a new proposal for combining the two properties point the way forward?
Transition metal oxides with a perovskite-type structure constitute a large group of compounds with interesting properties. Among them are materials such as the prototypical ferroelectric system BaTiO3, colossal magnetoresistance manganites and the high-T
c superconductors. Hundreds of these...
