One of the more studied manganese oxide-based cathodes is LiMn 2O 4, a cation ordered member of the structural family ( Fd3m). In addition to containing inexpensive materials, the three-dimensional structure of LiMn 2O 4 lends itself to high rate capability by providing a well connected framework for the insertion and de-insertion of Li ions during discharge and ch.

Thin-film solar cells are a type of made by depositing one or more thin layers ( or TFs) of material onto a substrate, such as glass, plastic or metal. Thin-film solar cells are typically a few nanometers () to a few microns () thick–much thinner than the used in conventional (c-Si) based solar cells, which can be up to 200 μm thick. Thin-film solar cells are commercially used in several technologies, including (.

Scientists have theorized that during the , Mars was created as the result of a of run-away accretion of material from the that orbited the Sun. Mars has many distinctive chemical features caused by its position in the Solar System. Elements with comparatively low boiling points, such as , , and , are much more common on Mars than on Earth; these elements were probably pushed outward by the yo.
