Novel SnO(2)-In(2)O(3) heterostructured nanowires were produced via a thermal evaporation method, and their possible nucleation/growth mechanism is proposed. We found that the electronic conductivity of the individual SnO(2)-In(2)O(3) nanowires was 2 orders of magnitude better than that of the pure SnO(2) nanowires, due to the formation of Sn-doped In(2)O(3) caused by the incorporation of Sn into the In(2)O(3) lattice during the nucleation and growth of the In(2)O(3) shell nanostructures. This provides the SnO(2)-In(2)O(3) nanowires with an outstanding lithium storage capacity, making them suitable for promising Li ion battery electrodes.

The proposed method is a robotic system for behavior intervention of children with autism who have deficit in development of communication and interaction with others. This robotic system helps the social training of children with autism in that robot reacts as a social being.We aim to improve the eye contact skill of children with autism, one of main indicators of their development. This paper describes our hardware configuration and methods for analyzing a child behavior based on vision and auditory information, and our human-robot interaction (HRI) architecture. At the end, preliminary experimental results with a non-autistic child will be presented.
