The solid complex [SnC1 4 (Et 2 O) 2 ] is instantly formed. The heat of reaction is sufficiently great to boil off some of the diethylether, sending clouds of the white complex into the air. As evident from the previous chapter, ammonia and related compounds such as trimethylamine form...

Microbial adaptation to salinity has been a classic inquiry in the field of microbiology. It has been demonstrated that microorganisms can endure salinity stress via either the “salt-in” strategy, involving inorganic ion uptake, or the “salt-out” str
Prediction of the Adsorption Capacity for Volatile Organic Compounds onto Activated Carbons by the Dubinin–Radushkevich–Langmuir Model were estimated simply from the properties of the VOCs using quantitative structure-activity relationship and from the pore size distribution of the adsorbent...

These polysaccharides are commonly depolymerized (Singh et al., 2016) by reactive oxygen species (ROS) which may lead to the aging of paper and wood (Ibn Yaich, Edlund, & Albertsson, 2012). ROS are a series of oxygen-containing compounds, such as hydroxyl radical (OH), superoxide (O2...
However, these ratios should be used with caution, because the degradation products of compounds may vary with time in the atmosphere14. Nitro-PAHs are formed directly from combustion processes such as those in diesel and gasoline engines, as well as by oxidants in the atmosphere through both ...
The biofilm and floc reactors both displayed distinct microbial community composition as determined by principal coordinate analysis (PCoA) on OTUs level (Fig. 2). Carbon source differences were mainly observed along the first principal coordinate (PCoA1), which accounted for 21.2% of total variation...
Professor As the earth developed, the concentrations of these pollutants were altered by various chemical reactions and become biogeochemical components, then they serve as air purification scheme by allowing the compounds to move from the air to the water or soil.Narrator Listen to part of a talk...
The main constituents of elastomers can often be analyzed with good accuracy by TGA. The technique can distinguish between volatile compounds, the polymer, carbon black and inorganic residues. Comments For accurate compositional analyses, a blank curve should be subtracted from the measured curve and ...
reducing bacteria (SRB) under anaerobic conditions. SRB can utilize the low molecular-weight organic matters as the carbon/energy substrates which are oxidized either completely to CO2and/or some intermediate compounds using sulfate as a terminal electron acceptor, consequently generating sulphide (Eq.1...
