The thermal stability of both polymers decreases upon the incorporation of phosphorus flame retardants irrespective of oxidation state and a greater amount of residue was observed in the case of phosphite. Phosphate was found to be better flame retardant in polyurea, whereas phosphite is suitable for...
THE STATE OF ELECTRON CARRIERS AND THE ADENOSINE TRIPHOSPHATE-PHOSPHATE EXCHANGE REACTION 1. Using rat liver mitochondria the relation of the ATP-iP exchange reaction to oxidative phosphorylation was studied. 2. Extreme reduction of the carriers inhibited the exchange more than oxidation of the ...
SEM images reveal that the coating of sample A is full of micro-holes, micro-cracks and many piece-like crystal particles, while that of sample B is integrated and compacted in glassy state with a few of micro-cracks. The coating of sample A is almost exhausted only in 8 h oxidized-...
Chemical oxidation increases the oxidation state of a contaminant and decreases the oxidation state of the reactant. The following is an example of an oxidation reaction (Table 5.5): Table 5.5. Effectiveness of chemical oxidation on general contaminant groups for liquids, soils, and sludge ...
which is believed to be a model for aging of post-replicative, non-dividing cells in multicellular organisms. Replicative aging is defined as the number of divisions an individual cell can accomplish before it enters a senescent, post-replicative state, modeling the aging of proliferating cells and...
The Great Oxidation Event thus represents a tipping point, whereby primary productivity and O2 production overwhelmed the input of reduced species that consume O2, and its timing is determined by the input of phosphate, the major limiting nutrient, and the dynamics of the solid Earth. Here, we ...

2. Steady-state chemisorption of hydrogen sulfide and sulfur dioxide by ammonia-phosphate solution One of the challenges of mathematical simulation of the hydrogen sulfide oxidation is the development of a liquid-phase oxidation model. This model along with the gas-phase model available is adequate ...
