Secondary aerosols formed from anthropogenic pollutants and natural emissions have substantial impacts on human health, air quality, and the Earth’s climate. New particle formation (NPF) contributes up to 70% of the global production of cloud condensation ...
Herein, we report the synthesis and characterization of a series of terminal uranium(IV) hydrosulfido and sulfido complexes, supported by the hexadentate, tacn-based ligand framework (Ad,MeArO)3tacn3– (= trianion of 1,4,7-tris(3-adamantyl-5-methyl-2-hydrox ...
The detailed description of gas streams in biomass gasification plants is necessary for the correct design and operation of these units. Sulfur containing compounds are usually present in biomass gasification gas, since sulfur is typically found in the fee ...
This work is focused on the numerical analysis of pollutant formation in an aviation gas turbine engine at different values of power setting. The analysis is conducted on the basis of a comprehensive approach treating the reactor net model for description ...
Atmospheric emissions of gas and particulate matter from a large ocean-going container vessel were sampled as it slowed and switched from high-sulfur to low-sulfur fuel as it transited into regulated coastal waters of California. Reduction in emission fact ...
The reduction of protons into dihydrogen is important because of its potential use in a wide range of energy applications. The preparation of efficient and cheap catalysts for this reaction is one of the issues that need to be tackled to allow the widespre ...
Chlorobaculum (Cba) tepidum is a green sulfur bacterium that oxidizes sulfide, elemental sulfur, and thiosulfate for photosynthetic growth. As other anoxygenic green photosynthetic bacteria, Cba tepidum synthesizes bacteriochlorophylls for the assembly of ...
Modern analogs are commonly used to investigate the relationships between modern pollen rain and the surrounding present vegetation and to improve our interpretation of fossil data. We collected modern pollen and spore rain in 18 more or less grazed and/or ...
This study experimentally analyzes the performance and degradation issues of an anode supported (AS) Ni-YSZ solid oxide fuel cell exposed to thiophene (C4H4S). The impact of this organic sulfur compound on the performance of SOFC Ni-YSZ anodes is reported ...
The Neoproterozoic sedimentary successions of the Sierras Bayas Group (SBG) are situated within the Tandilia Belt, Buenos Aires Province, Argentina. The Loma Negra Formation (LNF) from the upper part of the SBG has been investigated using a combination of ...
