To explore the mechanisms for formation of aromatic hydrocarbons as precursors to soot, a model system using combustion of biphenyl in a fuel rich flame is studied. The soots acquired at three different temperatures are solvent extracted and the extr

A novel analytical method based on laser desorption postionization mass spectrometry (LDPI-MS) was developed to investigate the competence and sporulation factor-a pentapeptide of amino acid sequence ERGMT-within intact Bacillus subtilis biofilms. De

Laser desorption mass spectrometry (LD-MS) was used to measure three asphaltenes, their sub-fractions separated using gel-permeation chromatography (GPC), and model compounds to ascertain their molecular weight distributions and averaged molecular we

X-ray diffraction (XRD) and small-angle X-ray scattering (SAXS) measurements were made on asphaltenes and vacuum residua (denoted by the prefixes As and VR, respectively) isolated from three different crude oilsMaya (MY), Khafji (KF), and Iranian Lig

The objective of this study is to examine changes in the structures of petroleum asphaltene aggregates in situ with small-angle neutron scattering (SANS). Asphaltenes were isolated from three different crude oils: Maya, Khafji, and Iranian Light. An

Mayan crude, residuum, and hydrocracked asphaltenes have been separated into two fractions by extended Soxhlet extraction in n-heptane. Although the solubility, composition, and molecular structures differ slightly, the greatest difference between th

Small angle neutron scattering (SANS) was used to investigate the structural changes of a 5 wt % asphaltene solution in perdeuterated 1-methylnaphthalene (1MN-d 10 ) as a function of temperature. A special stainless steel cell was constructed and use
