Gas sensitivity of polyaniline/SnO2 hybrids to volatile organic compounds GENG Li-na(耿丽娜) Department of Chemistry, Hebei Normal University, Shijiazhuang 050016, China Received 10 August 2009... mixing. Compared with single PAn and SnO2, the gas sensitivity of PAn/SnO2 materials to volatile organic compounds (VOCs, methanol, ethanol and acetone) was studied. The possible response mechanism......
Three-phase flow of submarine gas hydrate pipe transportLI Li(李立)1, 2, XU Hai-liang(徐海良)1, 2, YANG Fang-qiong(杨放琼)1, 2(1. State Key Laboratory of High Performance and Complex Manufacturing (Central...-suction mining natural gas hydrate, when the temperature-pressure equilibrium of gas hydrate is broken, gas hydrates dissociate into gas. As a result, solid-liquid two-phase flow (hydrate and water......
