This thesis describes efforts made on the development of an existing catalytic incinerator. The development work, called process characterization, consists of four general parts. These are the development of measurement methodology, the studying of construction materials, the selection of suitable catalysts and the testing of the effects of process operation conditions. The two application area...

UNLABELLED Although widely used in air quality regulatory frameworks, the term "volatile organic compound" (VOC) is poorly defined. Numerous standardized tests are currently used in regulations to determine VOC content (and thus volatility), but in many cases the tests do not agree with each other, nor do they always accurately represent actual evaporation rates under ambient conditions. The pa...

Numerous studies have revealed the extent of genetic and phenotypic variation between both species and cultivars of tomato. Using a series of tomato lines resulting from crosses between a cherry tomato and three independent large fruit cultivar (Levovil, VilB, and VilD), extensive profiling of both central primary metabolism and volatile organic components of the fruit was performed. In this st...

A dye-sensitized metal-organic framework, TMU-5S, was synthesized based on introducing the laser dye Rhodamine B into the porous framework TMU-5. TMU-5S was investigated as a ratiometric fluorescent sensor for the detection of explosive nitro aromatic compounds and showed four times greater selectivity to picric acid than any state-of-the-art luminescent-based sensor. Moreover, it can selective...

In this study, GC-MS and sensory evaluation were used to analyze the volatile components of fruits 2 white M. rubra purple . Meanwhile, their relationship among each other massion pine ( Pinus massoniana ) detected. The test results showed that, there 60 organic compounds (VOCs) in 8 categories, including aldehydes, acids, ketones, alcohols, esters, phenols, olefins alkanes, found four cultivar...

Chlorinated hydrocarbons and aromatics are the major volatile organic compounds that contaminate the ground water and industrial waste waters. The best way to overcome this problem is to recover the dissolved compounds in water. In order to evaluate the potential ability of granular activated carbon (GAC) for recovery of volatile organic compounds from water, the equilibrium adsorption was inve...

Bacteria use chemical signals to sense each other and to regulate various physiological functions. Although it is known that some airborne volatile organic compounds function as bacterial signalling molecules, their identities and effects on global gene expression and bacterial physiological processes remain largely unknown. Here we perform microarray analyses of Escherichia coli exposed to vol...
