China
Focus issueSince the opening of the country to the outside world thirty years ago, the output of scientific publications in materials science from China has risen from almost nowhere into now being the third largest in the world. In this special issue of Nature Materials we take a look at this rapid development in China.

Boosting migration
Letter by Abécassis et al.Developing novel strategies to drive or manipulate the migration of particles in solutions is important for lab-on-chip technologies, especially in the context of biological and chemical analysis. A strongly amplified and tunable migration of large particles using a passive transport phenomenon is now reported.

Nanowire lasers
Letter by Qian et al.Nanowire lasers have so far consisted of homogeneous semiconductor structures. The achievement of lasing from a multi-quantum-well heterostructure deposited on a nanowire demonstrates a new complexity in nanophotonic devices.

Magnetic molecules
Article by Train et al.Magneto-chiral dichroism is an effect in which unpolarized light is absorbed differently for parallel and antiparallel propagation with respect to an applied magnetic field. Previous observations have only seen a rather weak demonstration of this effect. Following a challenging synthesis, strong magneto-dichroism has now been obsereved in enantiopure chiral ferromagnets.

Organic spins
Article by McCamey et al.The observation of Rabi-oscillations between single and triplet states in an organic light-emitting diode demonstrates the possibility of manipulating the spin states in organic electronic devices. The data also provide direct evidence of very slow spin-dephasing, which should prove crucial for the development of organic spintronics.

Visualizing Li motion
Letter by Nishimura et al.Geometric information on lithium diffusion is crucial to understanding electrode reactions for lithium ion battery applications. Combining high-temperature powder neutron diffraction and the maximum entropy method, experimental evidence for a curved one-dimensional chain for lithium motion in LixFePO4 is now provided.
