But this time she kept away too long, and stayed beyond the half-hour; so she had not time to take off her fine dress, and threw her fur mantle over it, and in her haste did not blacken herself all over with soot, but left one of her fingers white.
Then he got hold of the fur and tore it off, and her golden hair and beautiful form were seen, and she could no longer hide herself: so she washed the soot and ashes from her face, and showed herself to be the most beautiful princess upon the face of the earth.
When Dickon began to walk about, Soot stayed on his shoulder and Captain trotted quietly close to his side.
And the burning smell is there--and the soot is there, and the oil is there--and he is not there
No one looks after it now my father is gone, and it has got all smirched with soot during my own boyhood.
Soots differ from one another depending on their source, even as soots from the same source can differ depending upon the conditions of their formation, says Michael Zachariah, a professor of mechanical engineering and chemistry at the University of Minnesota in Minneapolis.
Soots are complex and variable mixtures of chemical compounds, says Michael Verkouteren, leader of the Atmospheric Chemistry Group at the National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland, and that makes them difficult to characterize.
The NIST research spray combustion facility, where the synthetic soots will be created, does not emulate real-world conditions of industrial reactors such as furnaces or gas turbines; such systems are far too complex to reproduce in the lab.
Heptane is convenient for its simple composition, and a lot is known about its chemistry and its soots.
Yet for all the growing body of evidence of its impact, soot remains a pestilentially difficult substance to study.
Clean tubes whenever soots, scale or any residue accumulate.
Although soot can include respirable particles and carcinogens, the toxicologic and epidemiologic consequences of exposure to environmentally relevant complex soots have not been well investigated.
We evaluated these residues to gain insight into the chemical fine structure of the mixture, particularly with respect to PAHs in the semivolatile [78-300 atomic mass units (amu)] and high molecular weight range (300-1,000 amu); the free radicals present in the butadiene soot; and the cytotoxic, genotoxic, and morphologic alterations in NHBE cells following acute exposures to a dimethylsulfoxide (DMSO) extract of this butadiene soot (BSDE).
Weighed soot samples were Soxhlet-extracted for 6 hr using dichloromethane.
For electron spin resonance (ESR) studies, we obtained solvent-extractable free radicals from 1,3-butadiene soot from brief liquid-solid extractions with ultra-pure toluene, DMSO:water (4:1, v/v), n-hexane, and 3% aqueous sodium dodecyl sulfate.
