Clumped isotopes geothermometry was applied to two dolomitic hydrocarbon reservoirs. Results indicate that late burial dolomitization occurred at ~110°C in the Albian Pinda dolostone (offshore Angola) and ~90°C in the Mano-Meillon dolostone (Aquitaine Basin, France), and did not continue on during subsequent burial/thermal evolution to present-day conditions (150160°C). This study illustrates t...

filamentous fungus, is one of several industrial strains known for the production of arachidonic acid. It is also of particular interest for hydrocarbon biofuel production since it is able to produce up to 50% of its mass in rich, long-chain polyunsaturated fatty acids [PUFA’s]. M. alpina already has mechanisms for accumulating significant concentrations of hydrocarbon compounds, making it a na...

The stabilities and hydrocarbon/fluorocarbon sorption properties of a zeolite-like metal-organic framework (MOF) Zn(hfipbb) with fluorinated channels has been studied. By the combination of thermogravimetric analysis (TGA) and powder X-ray diffraction (PXRD) measurements, we confirm that Zn(hfipbb) has exceptionally high hydrothermal and thermal stabilities. The adsorption behaviors of water an...

The global consumer demand for portable electronic devices is increasing. The emphasis on reducing size and weight has put increased pressure on the energy and power densities of available power storage and generation options, which have been dominated by batteries. The energy densities of many hydrocarbon fuels exceed those of conventional batteries by several orders of magnitude, and this gap...

The reaction between the radical and the stable hydrocarbon is one of the simplest 2 22 neutral-neutral hydrocarbon reactions in chemical models of dense interstellar clouds and carbon-rich circumstellar shells. Although known to be rapid at temperatures o300 K, the reaction has yet to be studied at lower temperatures. We present here ab initio calculations of the potential surface for this rea...

Numerous studies have been done to determine the hydrocarbon potential of Malaysia’s formations and basins due need identify more conventional or unconventional resources. Due fact that none these investigations were carried out with any prior knowledge in relevant regions potential, some them did not, however, yield expected results. This study aims provide researchers all necessary informatio...

A self-consistent environment-dependent tight binding method is presented that was developed to simulate eigenvalue spectra, electron densities and Coulomb potential distributions for hydrocarbon systems. The method builds on a non-selfconsistent environment-dependent tight binding model for carbon [Tang et al., Phys. Rev. B 53, 979 (1996)] with parameters added to describe hydrocarbon bonds an...

in this study, the effect of hydrocarbon and rosin ester resins combination on the physical and mechanical properties of thermoplastic road markings were evaluated. at first, two basic thermoplastic road marking formulations based on hydrocarbon and rosin ester resins were prepared. several samples of the blends of two basic formulations for thermoplastic road marking were characterized and com...
