Disclosed is a positive electrode and a lithium battery including the positive electrode. The positive electrode includes a current collector, a first layer irreversibly deintercalating lithium ions, and a second layer allowing reversible intercalation and deintercalation of lithium ions. In one embodiment, the first layer further comprises a first sublayer and a second sublayer, in which the first sublayer is interposed between the current collector and the second sublayer. The first sublayer comprises a first active material represented by Formula 1 Li2Mo1-nR1nO3, and the second sublayer comprises a second active material represented by Formula 2 Li2Ni1-mR2mO2. In Formula 1, 0≦n≦1; and R1 is selected from the group consisting of manganese (Mn), iron (Fe), cobalt (Co), copper (Cu), zinc (Zn), magnesium (Mg), nickel (Ni), and combinations of at least two of the foregoing elements. In Formula 2, 0≦m≦1; and R2 is selected from the group consisting of Mn, Fe, Co, Cu, Zn, Mg, molybdenum (Mo), and combinations of at least two of the foregoing elements.

摘要:
A digital multimedia broadcast (DMB) receiver and a user interface including a processor that processes the received DMB signal and extracts information regarding ensembles and services from the DMB signal so that the user interface can display received services using the extracted information regarding the ensembles and services. The user interface can be a grid-type interface which includes an ensemble axis and a service axis to display multiple services linked to an ensemble along with the total duration of each service and the duration that each service has been viewed so that a user can easily determine the current status of each service.
摘要:
In a method and an apparatus for forming metal oxide on a substrate, a source gas including metal precursor flows along a surface of the substrate to form a metal precursor layer on the substrate. An oxidizing gas including ozone flows along a surface of the metal precursor layer to oxidize the metal precursor layer so that the metal oxide is formed on the substrate. A radio frequency power is applied to the oxidizing gas flowing along the surface of the metal precursor layer to accelerate a reaction between the metal precursor layer and the oxidizing gas. Acceleration of the oxidation reaction may improve electrical characteristics and uniformity of the metal oxide.

Phosphor mixtures for phosphor layers of plasma display devices are provided. The phosphor mixture includes a first compound selected from compounds represented by Gd1-yTbyAl3(BO3)4 (0.05≦Y≦0.8) and compounds represented by YBO3:Tb3+, and a second compound represented by Zn(Ga1-XAlx)2O4:Mn2+ (0.2≦X≦0.8). The first compound and second compound are mixed in a weight ratio ranging from about 3:7 to about 6:4. The inventive phosphor mixtures exhibit reduced decay times, thereby increasing color reproducibility and improving brightness characteristics.
