Richard Feynman's talk anticipating nanotechnology was inspirational, but no blueprint.
Cation binding is shown to trigger mesoscale domain formation within assembled mixtures of neutral and anionic polymer amphiphiles. The spotted and striped particles could be used for drug delivery or biomedical sensing.
Electron relaxation time in semiconductor quantum dots, for terahertz transition energies, can be slowed down to the nanosecond range — a very encouraging result for the development of quantum-dot-based quantum cascade lasers.
Secondary electron imaging in electron microscopy can achieve resolutions that compete with transmission electron microscopy, and allows imaging of both surface and bulk atoms simultaneously.
For more than 50 years, the International Conference on Magnetism series has been inspiring researchers in the field. At the latest meeting in Karlsruhe, Germany, the control exerted by nanostructured devices over magnetic properties was the centre of attention.
Control of the formation of nanostructures during their synthesis can be achieved using either equilibrium conditions, such as in nanostructure templating, or non-equilibrium conditions, such as in reaction–diffusion systems. This review analyses the different method types with the aim of...
High pressures have been very useful in stabilizing materials that cannot form at low pressure. However, often high-pressure phases are not stable when recovered in ambient conditions. Bombardment with high-energy heavy ions is now shown to stabilize a high-pressure phase of Gd2Zr2O7 in ambient...
In conventional metals, strong interactions between electrons and the atomic lattice, so-called polarons, often render metals electrically insulating. In the rare case of polaronic metals, however, polaronic properties survive even in the metallic state. Neutron-scattering experiments now reveal...
