The dislocation mechanisms involved in nanoscale deformation have so far been largely studied theoretically from atomistic simulations. High-temperature nanoindentation measurements provide a new quantitative experimental method of studying the onset of nanoscale plasticity.
A low-power light image projected on a photoconductive layer can initiate non-uniform electric fields over a large area, and allow the manipulation and sorting of particles without wires and electrodes and in the absence of flow.
Progress in all-organic electronic circuits has been hampered by the intrinsic low speed of organic devices. The fabrication of a fast organic rectifying diode opens the gate to novel applications.
Commercialization of organic electronics has been limited by the complex processing required to make large-scale devices from single crystals. A new approach exploiting composite phase behaviour facilitates the manufacture of crystalline films from solution for high-quality devices.
