Lithium-doped plastic crystal electrolytes exhibiting fast ion conduction for secondary batteries
Article Abstract:
Doping lithium ions into a plastic crystalline matrix has made it possible to produce a class of materials that have fast lithium ion motion because of rotational disorder and the presence of vacancies in the lattice. These materials can be categorized as fast ion conductors because of the high conductivities seen in a crystalline lattice. NMR relaxation measurements currently being undertaken should identify the various motional timescales that exist in these materials.

Latest spin on the core
Article Abstract:
Laske and Masters have taken a new approach to the problem of whether the Earth's inner core is rotating slightly faster than the mantle and crust. They have described an alternative seismological method for measuring inner-core differential rotation which is based on temporal variations of the splitting of the Earth's large free oscillations. They have concluded that the higher estimates of relative rotation rate can be rule out.

Ice on the fast track
Article Abstract:
The West Antarctic Ice Sheet (WAIS) has the ability to shrink rapidly leading to a rise in sea level. Bell and colleagues and Anandakrishnan and colleagues propose that ice streams in the WAIS only exist over sedimentary basins in the underlying ground. The interpretation is speculative and it is questioned whether the association between the ice stream and sediment is just coincidence.
