Temporal variations in Gaseous Elemental Mercury at a contaminated site

, 2016
Mercury is considered to be a global pollutant and it has been globally transported as gaseous elemental mercury (GEM). International networks for the continuous monitoring of mercury, all of which are based on background sites, study the dispersion pattern of this metal and trends in its evolution in time and space. However, information about seasonal

Development and First Results of an Aircraft-Based, High Time Resolution Technique for Gaseous Elemental and Reactive (Oxidized) Gaseous Mercury

, 2016
We developed a high time resolution (2.5 min) aircraft instrument for gaseous elemental mercury (GEM) and reactive gaseous mercury (RGM). The system measures RGM with complementary denuder and difference techniques, which can be compared to check for ...

Ni–Pd Catalytic Synergy on Rod‐Shaped CeO2 for Boosting Low‐Temperature CH4 Oxidation

EcoEnergy, EarlyView.
Introducing Ni into Pd/CeO2 markedly accelerates deep CH4 oxidation by inducing a synergistic interaction between Ni and Pd species. This synergistic effect significantly improves low‐temperature activity and long‐term stability, providing a rational strategy for efficient CH4 abatement over Pd‐based catalysts under lean CH4 conditions while reducing ...
