Ionic conductivity is a property where a material is able to conduct electricity through the movement of ions. Oxide ion conductors can be used in solid oxide fuel cells, which...

Materials that show fast oxide ion conduction have potential applications as electrolytes in devices such as solid oxide fuel cells (SOFCs), gas sensors and gas separation...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap andsafe cathodes. Recently, silicate-based cathodes have been described,...

Acceptor-doped perovskite oxides exhibit significant proton conductivity under humid or hydrogen containing atmosphere, which opens a unique possibility to be used as...

During the course of a PhD project funded by CCLRC's CMPC, we have developed a cell that allows electrical transport property measurements to be made simultaneously with the...

We have recently discovered that light metal amides and imides are excellent cattalysts for the decomposition of ammonia. We request 3 days on POLARIS to perform in situ neutron...

There has been recent interest in the use of cermets based on stabilised delta bismuth oxide based solid electrolytes as cathodes in solid oxide fuel cells. It has been shown...

CuI is well-known to exhibit the superionic behaviour in the high temperature solid state (α-phase), where the mobile Cu ions migrate among the interstices in the f.c.c....
