Reversible hydration of CH(3)NH(3)Pbl(3) in films, single crystals, and solar cells [PDF]
, 2015 Solar cells composed of methylammonium lead iodide perovskite (MAPI) are notorious for their sensitivity to moisture. We show that (i) hydrated crystal phases are formed when MAPI is exposed to water vapor at room temperature and (ii) these phase changes

Research on the Distribution Network’s Single-phase Short-circuit Faults with Wavelet Transform [PDF]
Advances in Intelligent Systems Research, 2015 According to the problem that the single phase grounding fault location is difficult to detect, a novel method of identifying fault line for single phase grounding fault is presented, based on the detailed analysis of the transient zero sequence network's fault characteristics in the small current neutral grounding power system.
