The inherently weak interactions between C60 and pentacene and the strong coupling of C60 with copper lead to a system reminiscent of a 2-molecule-thick Schottky diode, with a current rectification comparable with the best performers in the field of molecular diodes.
An X-ray microscopy technique recently developed has given scientists the ability to image nanoscale changes inside lithium-ion battery particles as they charge and discharge. The real-time images provide a new way to learn how batteries work, and how to improve them.
Self-destructing electronic devices could keep military secrets out of enemy hands. Or they could save patients the pain of removing a medical device. Or, they could allow environmental sensors to wash away in the rain.
Engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time.
An international team has introduced a three-dimensional X-ray diffraction technique for determining crystallographic texture - the preferred orientation of the little crystals in a solid - with previously unattainable spatial resolution.
