Intramolecular Hg[three dots, centered][small pi] interactions of d-character with non-bridging atoms in mercury-aryl complexes

26-Aug-2016 | A. Lannes; A. Manceau; M. Rovezzi; P. Glatzel; Y. Joly; I. Gautier-Luneau, Dalton Transactions, 2016

Mercury 5d-orbitals are involved in intramolecular π-interactions with carbon and sulfur nearest and next-nearest neighbors in mercury–aryl complexes. This unexpected character of the electron cloud of mercury was revealed by high energy-resolution XANES spectroscopy readily interpreted in terms ...

In situ crystalline transformation of bis(halo)mercury(II) coordination polymers to ionic chloro-bridged-bis(halo)mercury(II) species via UV irradiation in chloroform media

26-Aug-2016 | Eunkyung Choi; Haeri Lee; Tae Hwan Noh; Ok-Sang Jung, CrystEngComm, 2016

Self-assembly of HgX2 (X− = Br− and I−) with new 1,1,2,2-tetramethyl-1,2-di(pyridin-3-yl)disilane (L) ligand affords single crystals consisting of sinusoidal-strand coordination polymers, [HgX2L]. Specifically, 350 nm UV irradiation of crystalline products [HgBr2L] and [HgI2L] in chloroform media ...

IJERPH, Vol. 13, Pages 832: The Distribution and Health Risk Assessment of Metals in Soils in the Vicinity of Industrial Sites in Dongguan, China

19-Aug-2016 | Liu, Chao ; Lu, Liwen ; Huang, Ting ; Huang, Yalin ; Ding, Lei ; Zhao, Weituo, International Journal of Environmental Research and Public Health, 2016

Exponential industrialization and rapid urbanization have resulted in contamination of soil by metals from anthropogenic sources in Dongguan, China. The aims of this research were to determine the concentration and distribution of various metals (arsenic (As), cadmium (Cd), chromium (Cr), copper ...

Understanding the Impacts of Water Vapor on CaO Sulfurization in a Laboratory-Scale Fluidized Bed

19-Aug-2016 | Hui Wang; Shuai Guo; Dunyu Liu; Li Yang; Xing Wei; Shaohua Wu, Energy & Fuels, 2016

Limestone has been widely used to remove SO2 from circulating fluidized bed (CFB) boilers. As the main component of limestone, CaCO3 first undergoes calcination to CaO, which is then sulfated by SO2 to form CaSO4 in the furnace. Water vapor accounts for a high concentration in coal-fired CFB ...

Unsteady-State Diffusion of Gas in Coals and Its Relationship with Coal Pore Structure

19-Aug-2016 | Haijun Guo; Yuanping Cheng; Liang Yuan; Liang Wang; Hongxing Zhou, Energy & Fuels, 2016

Coalbed methane (CBM) is under consideration as a potential energy resource because of its global abundance. The exploitation and development of CBM depends on the correct characterization of coal structure and gas migration properties. In this paper, four coal samples with different degrees of ...

Current and Potential Future Bromide Loads from Coal-Fired Power Plants in the Allegheny River Basin and Their Effects on Downstream Concentrations

19-Aug-2016 | Kelly D. Good; Jeanne M. VanBriesen, Environmental Science & Technology, 2016

The presence of bromide in rivers does not affect ecosystems or present a human health risk; however, elevated concentrations of bromide in drinking water sources can lead to difficulty meeting drinking water disinfection byproduct (DBP) regulations. Recent attention has focused on oil and gas ...

Isotopic Composition of Atmospheric Mercury in China: New Evidence for Sources and Transformation Processes in Air and in Vegetation

17-Aug-2016 | Ben Yu; Xuewu Fu; Runsheng Yin; Hui Zhang; Xun Wang; Che-Jen Lin; Chuansheng Wu; Yiping Zhang; Nannan He; Pingqing F ..., Environmental Science & Technology, 2016

The isotopic composition of atmospheric total gaseous mercury (TGM) and particle-bound mercury (PBM) and mercury (Hg) in litterfall samples have been determined at urban/industrialized and rural sites distributed over mainland China for identifying Hg sources and transformation processes. TGM and ...

Mass-Dependent and -Independent Fractionation of Mercury Isotope during Gas-Phase Oxidation of Elemental Mercury Vapor by Atomic Cl and Br

17-Aug-2016 | Guangyi Sun; Jonas Sommar; Xinbin Feng; Che-Jen Lin; Maofa Ge; Weigang Wang; Runsheng Yin; Xuewu Fu; Lihai Shang, Environmental Science & Technology, 2016

This study presents the first measurement of Hg stable isotope fractionation during gas-phase oxidation of Hg0 vapor by halogen atoms (Cl•, Br•) in the laboratory at 750 ± 1 Torr and 298 ± 3 K. Using a relative rate technique, the rate coefficients for Hg0+Cl• and Hg0+Br• reactions are determined ...

The OH-Initiated Oxidation of CS2 in the Presence of NO: FTIR Matrix-Isolation and Theoretical Studies

17-Aug-2016 | A. Bil; K. Grzechnik; M. Sałdyka; Z. Mielke, Journal of Physical Chemistry A, 2016

We studied the photochemistry of the carbon disulfide–nitrous acid system with the help of Fourier transform infrared (FTIR) matrix isolation spectroscopy and theoretical methods. The irradiation of the CS2···HONO complexes, isolated in solid argon, with the filtered output of the mercury lamp (λ ...

Importance of Relativistic Effects and Electron Correlation in Structure Factors and Electron Density of Diphenyl Mercury and Triphenyl Bismuth

16-Aug-2016 | Lukáš Bučinský; Dylan Jayatilaka; Simon Grabowsky, Journal of Physical Chemistry A, 2016

This study investigates the possibility of detecting relativistic effects and electron correlation in single-crystal X-ray diffraction experiments using the examples of diphenyl mercury (HgPh2) and triphenyl bismuth (BiPh3). In detail, the importance of electron correlation (ECORR), relativistic ...
