Dibutyl phthalate aerosol particles evolution dynamics in a turbulent mixing layer is simulated by means of direct numerical simulation for the flow field and the direct quadrature method of moments for the aerosol evolution. Most particles are nucleated in a thin layer region corresponding to a specific narrow temperature range near the cool stream side. However, particles undergo high growth ...

A liquid obeys isochronal superposition if its dynamics is invariant along the isochrones in the thermodynamic phase diagram (the curves of constant relaxation time). This paper introduces two quantitative measures of isochronal superposition. The measures are used to test the following six liquids for isochronal superposition: 1,2,6 hexanetriol, glycerol, polyphenyl ether, diethyl phthalate, t...

A direct, sensitive, and rapid method for the detection of smokeless powder components, from five different types of ammunition, is demonstrated using laser electrospray mass spectrometry (LEMS). Common components found in powder, such as ethyl centralite, methyl centralite, dibutyl phthalate, and dimethyl phthalate, are detected under atmospheric conditions without additional sample preparatio...

The presence of N-nitrosamines was determined in samples of industrially manufactured liver patty stored at different temperatures for a variable period of time. Sample preparation included steam distillation and extraction of redistilled samples with dichlormethane. The extracts were analyzed by a gas chromatography--mass spectrometry system (GC-MS-SIM). Study results expressed as total N-nitr...

Abstract: This paper reports the results of an FT-IR and NIR study of N-methylformamide in carbon tetrachloride solution in presence of ethers as the O-electron donors, i.e., diethyl ether (DEE), diisopropyl ether (DiPE), methyl t-butyl ether (MtBE), dibutyl ether (DBE), dipentyl ether (DPE), tetrahydrofuran (THF) and tetrahydropyran (THP). The spectroscopic characteristics of the N–H···O hydro...

People are constantly exposed to phthalates, due their common use in the production of plastics, pharmaceuticals, cosmetics and skin care products. The ability phthalates disrupt endocrine signaling, leading developmental, reproductive metabolic defects, has been studied, yet how interfere with these biological functions is still unclear. To uncover DBP interacting molecular pathways, we raised...

Abstract Dibutyl ether (DBE) is a promising biofuel due to its high cetane number (~ 100) and volumetric energy density (31.6 MJ/L). It could either be used directly in compression ignition engines or blended with other conventional renewable fuels. Oxidation pyrolysis kinetics of DBE are not well known, particularly at pressures. In this work, we have experimentally investigated the chemical t...
