The temperature dependence of the magnetic shifts in the normal state of the anion-doped superconductor Nd2CuO3.7F0.3 are presented. The shifts due to the neodymium moments are subtracted off, to leave magnetic hyperfine shifts with a linear temperat

Tin pyrophosphate was synthesised and tested as an anode in lithium ion batteries. This material has a very good reversible capacity of 360 mA h g −1 with good capacity retention. The source of this good cycling behaviour is thought to be related t

A novel aluminum methylphosphonate, formula Al3(CH3PO3)2·O·(OH)3, has been prepared hydrothermally. Its structure was solved by a combination of 1-D MAS NMR and 2-D five-quantum MAS NMR spectroscopies, computational energy minimization using densit

Polymer electrolytes are the subject of intensive study, in part because of their potential use as the electrolyte in all-solid-state rechargeable lithium batteries. These materials are formed by dissolving a salt (for example LiI) in a solid host po
