Photophysical characterization of toluene and 3 pentanone for quantitative imaging of fuel/air ratio and temperature in combustion systems
… K) and absolute fluorescence quantum yields of 3-pentanone in dependence on excitation wavelength have been determined. A photophysical model that predicts toluene-LIF intensities in dependence on external variables (i.e. temperature, oxygen concentration, excitation wavelength) is developed. This …

New approaches for optical and microoptical diagnostics in IC engines
… (LIF) of the fuel tracers toluene and 3-pentanone. The respective total fluorescence signal and its spectral dis-tribution yield information about temperature, pressure and mixture composition (i.e. fuel/air-equivalence ratios). The fiber-optic spark plug is designed to perform LIF …

In cylinder liquid fuel visualization during cold start
… indolene and iso-octane doped with acetone and 3-pentanone was used to examine volatility effects. Images were taken on three planes through the cylinder and a number of post-processing techniques were used to analyze the results. The results were analyzed on both a time and crank-angle (CA) …

An Assessment of Perceived Crop Damage in a Tanzanian Village Impacted by Human-Elephant Conflict and an Investigation of Deterrent Properties of African Elephant (Loxodonta Africana) Exudates Using Bioassays
… Ranch in northern Tanzania, (E,E)-farnesol and 3-pentanone were bioassayed with wild African elephants. The compounds tested did not elicit bioactivity, but the importance of continued research on biologically meaningful signals is essential to effectively reducing HEC.

Equivalence Ratio Gradient Effects on Local Flame Front Topology and Heat Release Rate in Stratified, Iso-Octane/Air Turbulent V-Flames
… unique windowing approach was devised in which 3-pentanone tracer planar laser induced fluorescence (PLIF) was used to determine an analysis region of interest (ROI) within the flame. Iso-contours of equivalence ratio were traced up to the mean position of the flame front to define the width of …

The effects of solvents and nucleophiles on heteroaromatic SRN1 reactions
… Lastly, the SRN1 reactions of 2,4-dimethyl-3-pentanone with 2-bromopyridine and iodobenzene were accompanied by a reductive dehalogenation process. That these reactions involved the abstraction of s-hydrogens from the nucleophile was supported by the isolation of …

Hydrolysis and Atmospheric Oxidation Reactions of Perfluorinated Carboxylic Acid Precursors
… pathways. The compound perfluoro-2-methyl-3-pentanone (PFMP) is a new fire fighting fluid developed by 3M that is designed as a Halon replacement. The environment fate of PFMP with regards to direct photolysis, abiotic hydrolysis and hydration was determined using a combination of laboratory …
