The storage capacity of rechargeable lithium batteries is limited by their electrodes, especially the cathode. A layered copper vanadate material, which reacts electrochemically with lithium ions in an unexpected and reversible way, greatly expands the range of cathode choices.
A new design for reprogrammable microprocessors based on single magnetoresistive elements has the potential to thrust magnetoelectronics from journal concept to everyday product.
Introducing fluorine into the chemical formula of self-assembling supramolecular systems usually makes for more stable and robust lattices. Now a dendron molecule has been found for which fluorination brings about a change in the self-assembly motif and an unexpected supramolecular architecture.
The nanometre scale is a brave new world for scientists — mixing materials at such small dimensions can cause all sorts of surprising effects. New studies of experimental systems on the nanoscale further our understanding of these complex phenomena.
