Our knowledge of electromagnetic heating’s effect on heavy oil upgrading is largely based very limited data. The aim the present research was thus to study in detail microwave exposure absence and presence nanosized magnetite composition oil. obtained data reveal that use improves not only radiation application as a result its absorption release thermal energy but also these nanoparticles have ...

As part of our systematic exploration of chemical determinants for the olfactory potency of vapors towards humans, we measured concentration-detection functions for the odor of the homologous n-alkylbenzenes toluene, ethylbenzene, butylbenzene, hexylbenzene, and octylbenzene. A vapor delivery device based on dynamic olfactometry and calibrated by gas chromatography, served to test groups of 16 ...

The Transferable Potentials for Phase Equilibria-United .+tom (Tra.PPE-LJ.A) force ficki for hydrocarbons is extended to alkenes and alkylbenzenes by introducing the followins pseudo-atoms: CHZ (sp2), CH(sp2), C(sp2), CH(aro), R–C(aro) for the link to aliphatic side chains, and C (are) for the link of two benzene rings. In this united-atom force field. the nonbonded interactions of the hydrocar...

In this study, the use of linear alkylbenzenes (LABs) was employed to pinpoint sources human activity that cause detrimental impacts on coastal environment and river ecosystems. LABs were detected using GC–MS in sediment samples assembled from Kim River (KKR) Port Dickson coast (PDC). To assess significance variations distribution concentrations across sampling sites, study utilized several sta...

Cyclic Ethers (CEs) belong to a class of compounds importance understand the chemistry both engine auto-ignition hydrocarbon fuels and combustion oxygenated biofuels. This article, divided in six parts, aims at systematically analyzing how up-to-date experimental theoretical methods were applied unveil gas-phase oxidation these compounds. The first part gives brief overview on significance CEs ...
