Secondary organic aerosol (SOA), formed in the photooxidation of diesel fuel, biodiesel fuel, and 20% biodiesel fuel/80% diesel fuel mixture, are prepared under high-NOx conditions in the presence and absence of sulfur dioxide (SO2), ammonia (NH3), and relative humidity (RH). The composition of condensed-phase organic compounds in SOA is measured using several complementary techniques including...
Fossil melanin granules (melanosomes) are an important resource for inferring the evolutionary history of colour and its functions in animals. The taphonomy of melanin and melanosomes, however, is incompletely understood. In particular, the chemical processes responsible for melanosome preservation have not been investigated. As a result, the origins of sulfur-bearing compounds in fossil melano...
The present work is related to predicting the pKa values of organosulfur compounds through density functional theory (DFT). In this study, 22 were considered calculate theoretical values. main emphasis was given on substitution different groups sulfur atom. computations performed in presence dimethyl sulfoxide (DMSO) as solvent. Experimentally, order increase acidity is; sulfides < sulfoxide...
Organosulfur compounds classified as dibenzothiophenes (DBTs) and their derivatives are contained in petroleum. When used fuel, these substances release SOx emissions, thus contributing to air pollution, acid rain, climate change. Therefore, it is necessary reduce the content of organic sulfur fuels one way achieve this through bacterial desulfurization. This study reports biodesulfurization pr...
