The flow behavior of droplet on substrates is widespread in industry and nature, it a complex process multi-field coupling, involving two-phase droplet–substrate interaction. In this manuscript, we focus the fluid interfacial at junction gas–liquid–solid phases propose robust stable implementation algorithm to capture physical phenomena such as spreading with different wettability, using gas–liquid surface tension equilibrium contact angle input parameters. We apply under flat curved...

Abstract The northern region of Guangdong Province, China, has suffered from the extensive mining/milling uranium for several decades. In this study, surface waters in were analyzed by inductively coupled plasma optical emission spectrometry (ICP‐OES) concentrations (U), thorium (Th), and non‐radioactive metals (Fe, Mn, Mg, Li, Co, Cu, Ni, Zn). Results showed highly elevated studied radionuclides discharged effluents tailing seepage U sites. Radionuclide heavy metal also observed to be...

The distribution and the contamination level of uranium (U) thorium (Th) radionuclides potentially toxic metals, Cu, Li, Mn, Sr, Zn were investigated in surface sediments from aquifer systems around a industrial site northern Guangdong Province, China. Total contents these elements other major elements, including Fe, Al, Mg, Na, Ca, K, analyzed by inductively coupled plasma optical emission spectrometry. results show that U, Th, Mn are elevated recipient stream drains reservoir downstream....

Abstract Thallium (Tl) is a rare element of high toxicity. Sediments sampled in three representative locations near industries utilizing Tl‐containing raw materials from the Pearl River Basin, China were analyzed for their total Tl contents and four sequentially extracted fractions (i.e., weak acid exchangeable, reducible, oxidizable, residual fraction). The results reveal that (1.25–19.1 µg/g) studied sediments slightly to quite compared with those Chinese background sediments. This...

A multisite interface passivation material named 2-mercapto-4-methyl-5-thiazoleacetic acid (MMTA) is used to optimize the perovskite film top interface. DFT calculations and experiments show that MMTA can effectively passivate defects. Finally, champion device's photoelectric conversion efficiency reached 23.44%, which possessed long-term stability

Abstract Published annual‐to‐decadal‐resolution stalagmite δ 18 O records since AD 900 from six caves (Dongge, Furong, Heshang, Buddha, Shihua and Wanxiang) in China were analyzed to detect temporal spatial variability of the East Asian Summer Monsoon strength, which strongly affects wet/dry conditions eastern China. The empirical mode decomposition method was used obtain trends cave records. After base trend determined, anomalies each record computed by subtracting trend. Mean anomaly...

Abstract Four soil profiles were collected from locations with different distances (5, 50, 250 and 1000 m) a uranium mill tailings dam, Guangdong province, China, to investigate the pollution status of in mining/milling-related areas based on contents (U) thorium (Th), thus understand impacts industrial activities surroundings. The U Th concentrations determined by inductively coupled plasma mass spectrometry (ICP-MS) after conventional HF-HNO 3 -HClO 4 digestion procedures. results indicate...

For the problem that hard roof causes wider end‐mining coal pillar, and roadway is greatly affected by mining, this paper took Shanxi Luning Coal Mine as engineering background; based on stress distribution characteristics of calculation method limit pillar size was given; considering formation conditions transmission forms advanced abutment stress, a combining presplitting deep hole blasting proposed to weaken stress. The numerical simulation used analyze pillars, which verified on‐site...
