Significance Exceedingly high levels of fine particulate matter (PM) occur frequently in China, but the mechanism severe haze formation remains unclear. From atmospheric measurements two Chinese megacities and laboratory experiments, we show that oxidation SO 2 by NO occurs efficiently aqueous media under polluted conditions: first, during 1952 London Fog via in-cloud oxidation; second, on PM with NH 3 neutralization China. We suggest effective mitigation is achievable intervening sulfate...
Layered rock masses with joints are widely found in nature. Their mechanical behavior plays a key role engineering applications. However, previous studies have concentrated on the single lithologic layer, and few reported crack coalescence mechanism layered joints. In this study, uniaxial compression tests were performed jointed rock-like specimens two dissimilar layers. The acoustic emission (AE) digital image correlation (DIC) techniques employed to investigate process of influence joint...
Abstract As one of the most common disasters in deep mine roadway, floor heave has caused serious obstacles to transportation and normal production activities. The third section winch roadway mining area Qitaihe Longhu coal a due large buried depths semicoal rock maximum is 750 mm. For problem stability, this paper establishes mechanical model analyze stability by analogy with basement foundation pit. It provides reference for analyzing heave. Aiming at mine, established using FLAC3D, after...
The NH 4 PbI 3 ‐based phase transformation is realized by simply adding I additive, in order to simultaneously control perovskite nucleation and crystal growth. Regarding the process, + with small ionic radius preferentially diffuses into [PbI 6 ] 4− octahedral layer form , which compensates lack of CH (MAI) precipitation. generation intermediate results extra heterogeneous sites reduces defects derived from absence MA . growth cation exchange process between instead MAs directly entering,...
Abstract. Composition and size distribution of atmospheric aerosols from Xi'an city (~400 m, altitude) in inland China during the spring 2009 including a massive dust event on 24 April were measured compared with parallel measurement at summit (2060 Mt. Hua, an alpine site nearby Xi'an. EC (elemental carbon), OC (organic carbon) major ions 2–22 times higher than those mountaintop whole sampling period. Compared to that non-dust period sharp increase was observed both sites period, which...
Underground projects are typically performed in nonpersistent jointed rock masses. Excavation of tunnels or chambers causes crack initiation, propagation and coalescence, resulting the instability destruction surrounding rocks. The failure behaviour rocks is complicated owing to interaction between holes joints. Therefore, understanding characteristics masses essential. In this paper, mechanical a mass with double circular under uniaxial loading was investigated using discrete element...
The low-cost inorganic–organic lead halide perovskite materials become particularly promising for solar cells with high photovoltaic conversion efficiency. uniform and pinhole-free films play an important role high-performance cells. We demonstrate antisolvent treatment by controlling the PbI2 morphology to enhance photophysical properties, including absorption, crystallinity, rapid carrier transfer. fabricated show tremendous PCE improvement about 16.1% from 12% less hysteresis, retain over...
To understand the chemical evolution of dust in current East Asian atmosphere, chemistry PM2.5 and size-resolved aerosols Shanghai, China, during 2019 storm event was investigated. Our results showed that concentrations SO42- city highly correlated with Ca2+ Na+ due to direct emissions CaSO4 Na2SO4 from upwind deserts. In contrast, event, NO3- linearly NH4+ at a molar ratio close 1:1, both almost entirely stayed coarse particles, suggesting they accumulated on surface as NH4NO3. Based field...
Air quality forecasting is a significant method of protecting public health because it provides early warning harmful air pollutants. In this study, we used correlation analysis and artificial neural networks (ANNs; including wavelet ANNs [WANNs]) to identify the linear nonlinear associations, respectively, between pollution index (API) meteorological variables in Xi’an Lanzhou. Evaluating twelve algorithms nineteen network topologies for ANN WANN models, discovered that optimal input an API...
The failure and mechanical behavior of transversely isotropic rock are significantly affected by the original bedding planes. Until now, few studies have been performed to investigate influence geometrical parameters planes on fracture characteristics rocks under planar shear loading conditions. For this purpose, experimental numerical compression-shear tests double-notched specimens conducted fracturing loading. study that focuses plane inclination load, pattern AE evolution, six angles is...
Abstract. Molecular distributions and stable carbon isotopic (δ13C values) compositions of dicarboxylic acids related secondary organic aerosols (SOA) in PM2.5 collected on a day/night basis at the summit Mt. Tai (1534 m a.s.l.) summer 2016 were analyzed to investigate sources photochemical aging process forested highland region North China Plain. The molecular SOA are characterized by dominance oxalic acid (C2), followed malonic (C3), succinic (C4) azelaic (C9) acids. concentration ratios...
