Abstract Selective oxidation of saturated C( sp 3 )–H bonds in hydrocarbon to target chemicals under mild conditions remains a significant but challenging task because the chemical inertness and high dissociation energy bonds. Semiconductor photocatalysis can induce generation holes oxidative radicals, offering an alternative way toward selective hydrocarbons ambient conditions. Herein, we cons...

In the present work, a new macrocycle materials (SB77) was selected and Langmuir-Blodgett thin films of this compounds were examined for its vapor sensing capabilities against aromatic BTX hydrocarbons (benzene, toluene, xylene) through Quartz Crystal Microbalance (QCM) technique. accordance with aim, calix[4]arene LB prepared onto quartz crystal substrates. The characterization SB77 film perfo...

Adult epicuticular hydrocarbon variation of 14 geographically isolated populations of cactophilic Drosophila mojavensis was assessed to further investigate mechanisms of sexual isolation. Hydrocarbon transfer experiments demonstrated that these compounds are part of the mate recognition system in this species. Sixteen of the 23 epicuticular hydrocarbon components studied differed in amounts bet...

Petroleum hydrocarbon contamination is a major global prevalent issue in the petroleum sector. This research focuses on evaluating biodegradation of three Gram-negative bacilli, isolated from cowpea planted soil, contaminated with kerosene. The Gram negative bacilli strains have been characterized and identified, using MicrobactTM ID24E systems for the identification of Enterobacteriaceae and c...

The authors report on Langmuir probe measurements that show that hydrocarbon surfaces in contact with Ar plasma cause changes of electron energy distribution functions due to the flux of hydrogen and carbon atoms released by the surfaces. The authors compare the impact on plasma properties of hydrocarbon species gasified from an etching hydrocarbon surface with injection of gaseous hydrocarbons...

Geophysical investigations documenting enhanced magnetic susceptibility (MS) within the water table fluctuation zone at hydrocarbon contaminated sites suggest that MS can be used as a proxy for investigating microbial mediated iron reduction during intrinsic bioremediation. Here, we investigated community composition over 5-year period hydrocarbon-contaminated site exhibited transient elevated ...

This present paper investigates the conversion of organic matter in carbonate rocks Semiluksko-Mendymsky horizon Volga-Ural Basin under hydrothermal conditions with excess water subcritical at 613–653 K and 170–200 Bar. It has been found that content hydrocarbon extracts increases (relatively) which indicates oil-generating potential studied deposits. Besides, it shown undergoes oxidation react...

The specification of gasoline 91, according to Dirjen Migas decree No. 3674 K/24/DJM/2006 dated March,17 2006 define the limit (maximum) aromatic content 50%volume, and benzene 5.0% volume, but does not boundary for olefin as its is regulated in others countries. Olefin compound happened be saturated hydrocarbon, has higher octane number, unstable, produces gum that later on could build up depo...
