Using Hg2+ as a Precursor to Calibrate Gaseous Elemental Mercury from Pyrolysis of Coal

Yankuang ceshi, 2017
Mercury is easily volatile and vaporizes in air. The monitor of mercury in gas phase provides insight for developing advanced Hg control technologies. However, the analytical method of gas mercury is rudimentary.

Lattice Strain and Built‐In Field Synergistically Boost Urea Oxidation via Dynamic NiOOH Mediation at Multiphase Heterointerfaces

Advanced Materials, EarlyView.
A sulfur‐doped lignin‐derived carbon‐coated Ni‐NiO‐MoO2 nanorod array was synthesized, exhibiting enhanced UOR performance ‐ due to lattice‐strain and built‐in electric field effects by multiphase heterogeneous interface in Ni‐NiO‐MoO2@SC, excellent corrosion resistance, mass‐transport ability, and long‐term stability (500 mA cm−2 at 1.53 V for 500 h ...

Spatial‐Compatibility‐Assisted Molecular Intercalation in MXenes

Advanced Materials, EarlyView.
This work demonstrates a solvent–free NH4F–mediated route for simultaneous Al removal and molecular intercalation in MXenes. Intercalants are selected by comparing their crystallographic X, Y, and Z dimensions with the MXene interlayer spacing, establishing a spatial‐compatibility criterion that rationalizes guest–host matching and enables predictive ...

Hazards of Mercury – Safety Perspectives and Measures

Chemical Engineering Transactions, 2015
Mercury is one of the most hazardous contaminants emitted to the atmosphere due to its toxic effects on the environment and human health. Anthropogenic and geological sources account for 30 % and 10 % respectively, whereas the rest is from re-emissions ...

Model analyses of atmospheric mercury: present air quality and effects of transpacific transport on the United States [PDF]

Atmospheric Chemistry and Physics, 2013
Atmospheric mercury is a toxic air and water pollutant that is of significant concern because of its effects on human health and ecosystems. A mechanistic representation of the atmospheric mercury cycle is developed for the state-of-the-art global ...

Atom–Cluster Synergy in Scalable Fe–Ru Dual‐Site Architectures Accelerates Alkaline Hydrogen Evolution

Advanced Materials, EarlyView.
A mechanochemically synthesized dual‐site electrocatalyst (RuNC@Fe1NC) accelerates alkaline hydrogen evolution via atomic‐level spatial decoupling. Oxophilic Fe single atoms effectively dissociate water, while adjacent Ru nanoclusters rapidly recombine hydrogen.

A 2-year record of atmospheric mercury species at a background Southern Hemisphere station on Amsterdam Island [PDF]

Atmospheric Chemistry and Physics, 2014
Although essential to fully understand the cycling of mercury at the global scale, mercury species records in the Southern Hemisphere are scarce. Under the framework of the Global Mercury Observation System (GMOS) project, a monitoring station has been

Airborne Vertical Profiling of Mercury Speciation near Tullahoma, TN, USA

Atmosphere, 2014
Atmospheric transport and in situ oxidation are important factors influencing mercury concentrations at the surface and wet and dry deposition rates. Contributions of both natural and anthropogenic processes can significantly impact burdens of mercury on

Long-Term Observations of Atmospheric Speciated Mercury at a Coastal Site in the Northern Gulf of Mexico during 2007–2018

Atmosphere, 2020
Atmospheric mercury species (gaseous elemental mercury (GEM), gaseous oxidized mercury (GOM), and particulate-bound mercury (PBM)), trace pollutants (O3, SO2, CO, NO, NOY, and black carbon), and meteorological parameters have been continuously measured ...
