As moves towards open-access schemes gain momentum, the choice between 'author pays' and subscription-based models may come down to fundamental business considerations rather than limits in access to original research.
Metamaterials have seen many exciting applications. A design that is able to circumvent singularities in refractive index now allows a broad range of new applications, including an omnidirectional retroreflector.
Solid liquid crystals couple orientational order and mechanical strain, enabling fundamentally new mechanisms of actuation. Depositing the materials using inkjet printing allows precise control of their shapes and composition, producing devices with new microfluidic applications.
Investigation of the phase diagram of the structurally simple compound FeSe may prove instrumental in raising the transition temperature in Fe-based superconductors and in understanding magnetic-mediated superconductivity.
With liquid-crystal displays now ubiquitous in everyday life, liquid-crystal research is moving beyond these applications and evolving in entirely new and unexpected directions.
Ionic liquids are room-temperature molten salts, composed mostly of organic ions that may undergo almost unlimited structural variations. This review covers the newest aspects of ionic liquids in applications where their ion conductivity is exploited; as electrochemical solvents for...
Superconductivity was recently observed in the binary iron-based compound, FeSe. It is now shown that under pressure, the transition temperature can rise above 36 K. In addition, no static magnetic ordering is observed for this system, contrary to FeAs superconductors.
The electric control of magnetism in magnetic devices has remained problematic, particularly as energy losses due to current flow can be large. The demonstration of electric control of magnetization in a non-centrosymmetric insulating magnetic material therefore represents a new strategy for...
