ZigBee technology has been developed to provide capable wireless networking between numerous low-power devices for industrial monitor, industrial automated manufacturing, home automation and etc. and ZigBee products are getting more and more attentions in the world. Many research teams and manufacturers in these areas are focusing on development of advanced ZigBee applications for their good marketing prospect. But lacking of a standard communication interface between ZigBee applications and ZigBee network nodes is a big problem of developing ZigBee products at the software level because combination control of these two parts brings high complexity and high cost of product development and creates a barrier for further developer of ZigBee. In this paper we present a generic and united interface for ZigBee applications. Architecture of ZigBee network is blocked off from application developer, so modular development and convenient upgrade is provided for ZigBee products.

Correlation between the thermal stability and electro-affinity of a nanosolid has been explored from the perspective of surface and interface bonding. It turns out that the coherency of atoms at the boundary skin and the portion change of such skin atoms dominate the shift of critical temperatures (TC) for phase transitions of the nanosolid. Trapping potential well depression not only shifts the valence density-of-state positively but also enlarges the electro-affinity and hence the strength of bonds in the skins. In particular, bond-nature alteration at the junction interface, or with the reduced atomic coordination of atoms with valence 3 or 4, dominates the irregular TC shift of the embedded or the naked nanosolids. Atoms in the ‘superficial’ or the ‘interfacial’ skins play the core role in dictating the size effect on the thermal stability and electro-affinity of a nanosolid whereas atoms in the core interior remain as they are in the bulk.
