TL;DR: HMs emissions from specified anthropogenic sources under three different control scenarios for the target year 2015 are projected, and collaborative and specialized control strategies are proposed to meet the demand of emission reduction goals of different regions.
Abstract: A bottom-up inventory of atmospheric emissions of five precedent-controlled toxic heavy metals (HMs), including mercury (Hg), arsenic (As), lead (Pb), cadmium (Cd), and chromium (Cr), from primary anthropogenic sources in China is established for the period 2000–2010. Total emissions of HMs demonstrate a gradually ascending trend along with the increase of coal consumption and industrial production, which are estimated at approximately 842.22 t for Hg, 4196.31 t for As, 29272.14 t for Pb, 795.29 t for Cd, and 13715.33 t for Cr for 2010. Coal combustion is found to be the primary source of HMs emissions. Owing to the dramatic differences of coal use by industrial and power sectors among provinces, spatial allocation performs remarkably uneven characteristics, and spatial distribution features are demonstrated by allocating the emissions into 0.5° × 0.5° grid cells with GDP and population as surrogate indexes. Further, HMs emissions from specified anthropogenic sources under three different control scenarios for the target year 2015 are projected, and collaborative and specialized control strategies are proposed to meet the demand of emission reduction goals of different regions. In the future, a whole processes control management system will be the most effective way for control of HMs.

TL;DR: The result shows that both the surface-bound SO4- and OH play significant roles during the degradation process, where the electron transfer of Co2+/Co3+, Bi3+/Bi5+, and Ni2/Ni3+ realizes the sustained regeneration of the active radicals.

TL;DR: Porous phosphorized CoNi2 S4 yolkshell spheres (P-CoNi2S4 YSSs) were designed and synthesized by a combined hydrothermal sulfidation and gas-phase phosphorization strategy as discussed by the authors.
Abstract: Exploring earth-abundant electrocatalysts with excellent activity, robust stability, and multiple functions is crucial for electrolytic hydrogen generation. Porous phosphorized CoNi2 S4 yolk-shell spheres (P-CoNi2 S4 YSSs) were rationally designed and synthesized by a combined hydrothermal sulfidation and gas-phase phosphorization strategy. Benefiting from the strengthened Ni3+ /Ni2+ couple, enhanced electronic conductivity, and hollow structure, the P-CoNi2 S4 YSSs exhibit excellent activity and durability towards hydrogen/oxygen evolution and urea oxidation reactions in alkaline solution, affording low potentials of -0.135 V, 1.512 V, and 1.306 V (versus reversible hydrogen electrode) at 10 mA cm-2 , respectively. Remarkably, when used as the anode and cathode simultaneously, the P-CoNi2 S4 catalyst merely requires a cell voltage of 1.544 V in water splitting and 1.402 V in urea electrolysis to attain 10 mA cm-2 with excellent durability for 100 h, outperforming most of the reported nickel-based sulfides and even noble-metal-based electrocatalysts. This work promotes the application of sulfides in electrochemical hydrogen production and provides a feasible approach for urea-rich wastewater treatment.

TL;DR: In this paper, the authors considered the Fisher-KPP problem with a free boundary governed by a one-phase Stefan condition, and established the existence and uniqueness of the weak solution, and through suitable comparison arguments, extended some of the results obtained earlier in Du and Lin (2010) [11] and Du and Guo (2011) to this general case.

TL;DR: In this paper, the performance of CoFe2O4/HPC nanoparticles was investigated in the presence of peroxymonosulfate and showed that the graphitized structure and the synergistic effect between graphitized structures and CoFe 2O4 nanoparticles were the main factors responsible for the superior performance of the nanoparticles compared to other catalysts.
