Silver nanoparticles were prepared adopting microwave synthesizing method and coated on the optical fiber lateral utilizing a self-assembling technology. An optical fiber sensor based on localized surface plasmon resonant (LSPR) was developed. UV-vis extinction spectrum of the optical fiber modified nanoparticles was investigated with a fiber spectrometer. The results show that LSPR extinction peak...
This paper focused on the effects of waste activated sludge (WAS) and surfactant sodium dodecylbenzene sulfonate (SDBS) addition on primary sludge (PS) hydrolysis and short-chain fatty acids (SCFA) accumulation in fermentation. The results showed that sludge hydrolysis, SCFA accumulation, NH4+–N and PO43-–P release, and volatile suspended solids (VSS) reduction were increased by WAS addition to PS,...
An accurate network topology is important to network performance monitoring, configuration management, and fault locating. However, due to the rapid development of network technology, the traditional IPv4 topology discovery method can't satisfy the needs of network management any more. Moreover, many kinds of IPv4&IPv6 transition mechanism deployed in the network bring huge challenge to network...
