Catalytic access to alkyl bromides, chlorides and iodides via visible light‐promoted decarboxylative halogenation

18-May-2016 | Lisa Candish, Eric Standley, Adrian Gomez-Suarez, Satobhisha Mukherjee, Frank Glorius, Chemistry - A European Journal, 2016

Herein is reported the catalytic, visible light‐promoted, decarboxylative halogenation (bromination, chlorination, and iodination) of aliphatic carboxylic acids. This operationally‐simple reaction tolerates a range of functional groups, proceeds at room temperature, and is redox neutral. By ...

Two Centuries of Coral Skeletons from the Northern South China Sea Record Mercury Emissions from Modern Chinese Wars

18-May-2016 | Ruoyu Sun; Holger Hintelmann; Yi Liu; Xiaohua Li; Brian Dimock, Environmental Science & Technology, 2016

The contemporary mercury (Hg) cycle in the world’s oceans has been greatly affected by human activities. However, we are still lacking reliable, long-term, and continuous records of Hg in seawater. Here, we report for the first time on using annually banded Porites coral skeletons from the ...

Experimental Study on Mercury Oxidation in a Fluidized Bed under O2/CO2 and O2/N2 Atmospheres

18-May-2016 | Hui Wang; Yufeng Duan; Ya-ning Li; Meng Liu, Energy & Fuels, 2016

The effects of the temperature, oxygen concentration, and excess oxygen coefficient on mercury oxidation under O2/CO2 and O2/N2 coal combustion were experimentally analyzed in a fluidized bed. The results suggested that both the concentration and proportion of Hg0 increased as the temperature ...

Sustainability, Vol. 8, Pages 480: Spatial Assessment of Cancer Incidences and the Risks of Industrial Wastewater Emission in China

14-May-2016 | Li, Yingru ; Li, Huixuan ; Liu, Zhongwei ; Miao, Changhong, Sustainability, 2016

China’s rapid economic growth and social transitions have deteriorated environmental conditions and caused further public health issues in last three decades. This study examines the complex mechanisms of how socioeconomic transitions and physical environmental conditions impact public health, ...

IJERPH, Vol. 13, Pages 495: Combined Effects of Prenatal Exposures to Environmental Chemicals on Birth Weight

12-May-2016 | Govarts, Eva ; Remy, Sylvie ; Bruckers, Liesbeth ; Den Hond, Elly ; Sioen, Isabelle ; Nelen, Vera ; Baeyens, Willy ; ..., International Journal of Environmental Research and Public Health, 2016

Prenatal chemical exposure has been frequently associated with reduced fetal growth by single pollutant regression models although inconsistent results have been obtained. Our study estimated the effects of exposure to single pollutants and mixtures on birth weight in 248 mother-child pairs. ...

Model‐based optimization of the feeding policy of a fluidized bed bioreactor for mercury uptake by immobilized Pseudomonas putida cells

10-May-2016 | Andreea Georgiana Şcoban, Gheorghe Maria, Asia-Pacific Journal of Chemical Engineering, 2016

ABSTRACT A model‐based analysis of a three‐phase continuously operated fluidized bed bioreactor is developed in order to determine the multi‐objective optimal feeding policy of the immobilized biomass used for removing mercury ions from wastewater. The analysis is focus on finding the optimal ...

Porous structure of fibre networks formed by a foaming process: a comparative study of different characterization techniques

09-May-2016 | AHMAD M. AL‐QARARAH, AXEL EKMAN, TUOMO HJELT, HARRI KIISKINEN, JUSSI TIMONEN, JUKKA A. KETOJA, Journal of Microscopy, 2016

Summary Recent developments in making fibre materials using the foam‐forming technology have raised a need to characterize the porous structure at low material density. In order to find an effective choice among all structure‐characterization methods, both two‐dimensional and three‐dimensional ...

Mechanism of Heterogeneous Mercury Oxidation by HBr over V2O5/TiO2 Catalyst

09-May-2016 | Zhen Wang; Jing Liu; Bingkai Zhang; Yingju Yang; Zhen Zhang; Sen Miao, Environmental Science & Technology, 2016

Catalytic oxidation of elemental mercury (Hg0) through a selective catalytic reduction (SCR) system is a promising method to reduce mercury emissions from coal-burning power plants. The density functional theory (DFT) and periodic slab models were used to study the reaction mechanism of Hg0 ...

Preparation of Fly-Ash-Modified Bamboo-Shell Carbon Black and Its Mercury Removal Performance in Simulated Flue Gases

05-May-2016 | Rui Tang; Wei Yang; Hui Wang; Jie Zhou; Zhixiao Zhang; Shengji Wu, Energy & Fuels, 2016

Toxic mercury emissions from various industrial sources, especially coal combustion, have become an increasing concern in recent years, and effective methods of removing these emissions from coal combustion flue gases are being sought. In this study, fly-ash-modified bamboo-shell carbon blacks ...
