Revisit to the biodesulfurization capability of hyperthermophilic archeon Sulfolobus Solfataricus P2 revealed DBT consumption by the organism in an oil/water two-phase liquid system at high temperatures [PDF]

open access: yes, 2014
The ability of hyperthermophilic archaeon, Sulfolobus solfataricus P2, to grow on organic and inorganic sulfur sources was investigated. A sulfur free mineral medium has been employed with different sources of carbon.

Modelling of the Kinetics of Sulfure Compounds in Desulfurisation Processes Based on Industry Data of Plant [PDF]

open access: yes, 2016
Modelling of sulfur compounds kinetics was performed, including kinetics of benzothiophene and dibenzothiophene homologues. Modelling is based on experimental data obtained from monitoring of industrial hydrotreating set. Obtained results include kinetic

Easy Preparation of Carbon Nano Onion—Poly Ionic Liquid‐Like Hybrids Through the Deep Eutectic Monomer (DEM) Approach and Their Use in Heterogeneous Catalysis

open access: yesAdvanced Sustainable Systems, Volume 10, Issue 2, February 2026.
Carbon nano‐onions (CNOs) are rapidly functionalized using polymerizable deep eutectic solvents (PDESs), which serve as both dispersing media and reagents. This green approach introduces polymers endowed with –OH, –NH3⁺Br−, and –SO3− groups onto CNO surfaces.

Evaluación de la actividad desulfurizadora de aislados nativos de Pseudomonas spp. en presencia de hidrocarburo

open access: yesRevista Colombiana de Biotecnología, 2005
El principal inconveniente en la combustión de los hidrocarburos es la conversión del azufre y el nitrógeno a sus respectivos óxidos, los cuales participan en la formación de lluvia acida y deterioran el medio ambiente e infraestructuras.

Removal of refractory organosulfur compounds via oxidation with hydrogen peroxide on amorphous Ti/SiO2 catalysts [PDF]

open access: yes, 2010
Efficient removal of benzothiophene (BT), dibenzothiophene (DBT) and 4,6-dimethyldibenzothiophene (DMDBT) has been successfully achieved via oxidation with hydrogen peroxide in liquid phase using an amorphous silica-loaded titanium oxide catalyst.

Recent Advances in Mediator and Proton Relay Usage in Molecular Catalysis

open access: yesAdvanced Science, Volume 13, Issue 8, 9 February 2026.
The use of electron–proton transfer mediators, redox mediators, and proton relays in synergy with molecular catalysts in energy‐related small‐molecule and organic transformations is discussed, with a focus on recent advances. Linear free‐energy relationship and catalytic Tafel plots provide a systematic foundation for benchmarking these catalytic ...

Introducing the Cis‐2,3‐Bis(trifluoromethyl)cyclopropyl Chemotype: Late‐Stage Installation and Stereoelectronic Properties

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
The cis‐2,3‐bis(trifluoromethyl)cyclopropyl chemotype is introduced. The steric demand of this motif is intermediate between that of the heptafluoroisopropyl and prefluorotertbutyl groups; yet, it induces significantly less lipophilicity than these due to its facial polarity.

Enhancement of dibenzothiophene desulfurization by Gordonia alkanivorans strain 1B using sugar beet molasses as alternative carbon source [PDF]

open access: yes, 2014
There are several problems limiting an industrial application of fossil fuel biodesulfurization, and one of them is the cost of culture media used to grow the microorganisms involved in the process.
