Background Biosurfactants are naturally derived products that play a similar role to synthetic dispersants in oil spill response but are easily biodegradable and less toxic. Using a combination of analytical chemistry, 16S rRNA amplicon sequencing and simulation-based approaches, this study investigated the microbial community dynamics, ecological ...

CO2 reforming of methane was studied at medium temperature (700 °C) using a GSHV of 48,000 h–1 over nickel catalysts supported on ZrO2 promoted by alumina. The catalysts were prepared by a one-step synthesis method and characterized by BET, H2-TPR, XRD, XPS, TEM, Raman spectroscopy, and TGA. The NiO–10Al2O3–ZrO2 catalyst exhibited higher catalytic ...

In this paper, we report the first grand canonical Monte Carlo simulation study aiming at characterizing the competitive trapping of CH4 and C2H6 molecules into clathrate hydrates under temperature conditions typical of those encountered at the surface of Titan. Various compositions of the fluid in contact with the clathrate phase have been conside...

La migration des fines dans les formations fracturées est une cause majeure de la perte de production d’hydrocarbures. Ces fines vont adhérer à la surface des fractures et au proppant, et ainsi colmater les drains hydrauliques, réduisant localement la perméabilité des fractures ainsi que la production globale du puits. Il a été découvert que la sti...

The contamination of the environment by crude oil and its by-products, mainly composed of aliphatic and aromatic hydrocarbons, is a widespread problem. Biodegradation by bacteria is one of the processes responsible for the removal of these pollutants. This study was conducted to determine the abilities of Burkholderia sp. B5, Cupriavidus sp. B1, Ps...

Dolomitization in the Western Canada Sedimentary Basin (WCSB) has been extensively researched, with previous studies primarily focussing on hydrocarbon reservoirs hosted within differentially dolomitized Middle to Upper Devonian strata, and on Mississippi-Valley-Type lead-zinc deposits within pervasively dolomitized Middle Cambrian strata. This has...

The stereoselective germylzincation of internal alkynes delivering trisubstituted vinylgermanes is achieved via a radical chain process involving Ph3GeH and Et2Zn with AIBN as initiator. Excellent levels of regiocontrol are observed for non-symmetric (aryl, alkyl)-substituted alkynes, as well as for propargylic alcohols with aryl-, alkyl-, or silyl...

A bacterial strain was isolated from an oil-contaminated site and on its’ further characterization, exhibited the potential of synthesising metabolites and the ability to degrade crude oil. Its’ morphological, biochemical and 16S rRNA analysis suggested that the bacterium belongs to Dietzia maris AURCCBT01. This strain rapidly grew in the medium su...

Le comportement de phase des fluides de réservoir est une information cruciale pour prévoir des procédés de production pétrolière efficace. Selon les caractéristiques du fluide, le comportement de phase peut varier de simples équilibres liquide-vapeur à des systèmes multiphasiques plus complexes. Ces équilibres multiphasiques peuvent être rencontré...

A method for the visualisation of chemical shielding tensors (VIST) is developed, which provides a graphical representation of aromaticity and antiaromaticity, their local variations, and anisotropy. The method provides unique insight into fascinating phenomena such as the interplay of aromaticity and antiaromaticity in macrocycles with competing π...
