Abstract: An anode active material and a lithium battery employing the same are provided. In one embodiment of the anode active material, a —(CH2CH2O)— repeating unit is bonded to the surface of metal particles that contain metals that can be alloyed with lithium. The repeating unit prevents reactions between the metal particles and the electrolyte solution. Also, due to its elasticity, the repeating unit absorbs part of the volume expansion of the metal particles. The repeating unit also prevents the metal particles from condensing, thereby enhancing dispersion properties. Accordingly, the inventive anode active material has high capacity and excellent capacity retention during repeated charging and discharging, thereby providing a lithium battery with a long cycle life.

Abstract: Provided are a cyclopentaphenanthrene-based compound and and an organic light emitting device employing the same. The cyclopentaphenanthrene-based compound can be easily prepared, has high thermal stability and excellent hole transporting capability, and can be efficiently used to form an organic layer, particularly, a hole transport layer.

Abstract: The present invention provides a method of using a processor to create a linked information object the information object being formed from content having a respective type. The processor is coupled to a display and a store, to allow the processor to obtain an information object and assign a unique identifier thereto in accordance with the information object type. One or more links are then defined between the information object and one or more other information objects, either using predetermined rules, or input commands from a user. The computer then generates link data defining the one or more links, which is stored in the store.
