This work reports a facile method for preparing the new photoactive In(2)O(3) films as well as their implementation in photoelectrochemical (PEC) application. We firstly investigated the relationship between oxygen vacancies (V(O)) and PEC performance and revealed a rule between them. We found that the optimized In(2)O(3-n) sample yielded a photocurrent(More)
IEEE 802.15.4 and IEEE 802.11b/g work in the same 2.4GHz ISM (Industrial Scientific and Medical) band, their coexistence is crucial to ensure both of them work efficiently under the interference of each other. In this paper we investigated the above issue through extensive indoor measurements in a systematic way. The experimental results show that (1)(More)

It is important to protect power supply grid system against various damages for national economics. A high-voltage transmission line monitoring system is an effective way to protect the power supply system. This paper presents an energy-efficient data gathering mechanism for such a system. Our contributions are two-fold: (1) a detailed measurement of the(More)
