Understanding the movement of domain walls is important for the development of fast spintronic devices. In nanowires, this domain-wall motion is found to show a complex behaviour.
Long-lasting charge separation is key to the performance of solar cells. A new design for larger conjugated dye-sensitizer molecules effectively retards the recombination of the charge-separated state and promises improved energy conversion efficiency.
Magnetic nanoparticles are useful for a wide range of applications from data storage to medicinal imaging. The large-scale preparation of FeCo nanoparticles boosts this potential.
The ability to change their dimensions in an applied electric field makes ferroelectric materials important for piezoelectric applications. The crystal symmetry and related strains of these materials are a strong influence on their switching behaviour.
