Transient and intermediate carbocations in ruthenium tetroxide oxidation of saturated rings

open access: yesBeilstein Journal of Organic Chemistry, 2019
The ruthenium tetroxide-mediated oxidation of cyclopentane, tetrahydrofuran, tetrahydrothiophene and N-substituted pyrrolidines has been studied computationally by DFT and topological (analysis of the electron localization function, ELF) methods.

Salix purpurea and Eleocharis obtusa Rhizospheres Harbor a Diverse Rhizospheric Bacterial Community Characterized by Hydrocarbons Degradation Potentials and Plant Growth-Promoting Properties

open access: yesPlants, 2021
Phytoremediation, a method of phytomanagement using the plant holobiont to clean up polluted soils, is particularly effective for degrading organic pollutants.

Comparative Genomic Analysis and Functional Identification of CER1 and CER3 Homologs in Rice Wax Synthesis

open access: yesBiology
Alkane is a predominant wax component, whose production requires the aids of CER1 and CER3. In rice, OsCER1 and OsCER3 are present in multiple copies. Until now, the roles of these genes have been studied individually; however, a systematic comparison of

Features of the Hydrocarbon Distribution in the Bottom Sediments of the Norwegian and Barents Seas

open access: yesFluids, 2021
The results of the study of hydrocarbons (HCs): aliphatic (AHCs) and polycyclic aromatic hydrocarbons (PAHs) in bottom sediments (2019 and 2020, cruises 75 and 80 of the R/V Akademik Mstislav Keldysh) in the Norwegian-Barents Sea basin: Mohns Ridge ...

Paired genomic and proteomic analysis of Acinetobacter towneri from waste sludge reveals an extensive repertoire of enzymes for breakdown of hydrocarbons

open access: yesMicrobiology Spectrum
Crude oil, primarily consisting of alkanes, and plastic derivatives are integral to modern society, yet their widespread use has led to persistent pollution that devastates ecosystems worldwide. Enzymatic and microbial biodegradation are highly desirable

Characterization of the Mycoremediation of n-Alkanes and Branched-Chain Alkanes by Filamentous Fungi from Oil-Polluted Soil Samples in Kazakhstan

open access: yesMicroorganisms, 2023
For decades, researchers have focused on containing terrestrial oil pollution. The heterogeneity of soils, with immense microbial diversity, inspires them to transform pollutants and find cost-effective bioremediation methods.

Corksorb Enhances Alkane Degradation by Hydrocarbonoclastic Bacteria

open access: yesFrontiers in Microbiology, 2021
Biosorbent materials are effective in the removal of spilled oil from water, but their effect on hydrocarbonoclastic bacteria is not known. Here, we show that corksorb, a cork-based biosorbent, enhances growth and alkane degradation by Rhodococcus opacus

On the shear-thinning of alkanes

open access: yesTribology Letters, 2023
Abstract The approximate power-law dependence ofthe apparent viscosity of liquids on shear rate is of-ten argued to arise from a distribution of energy barri-ers. However, recent work on the Prandtl model, whichconsists of a point mass being dragged by a damped,harmonic spring past a sinusoidal potential, revealed asimilar dependence of the ...

Novel Cage-Like Hexanuclear Nickel(II) Silsesquioxane. Synthesis, Structure, and Catalytic Activity in Oxidations with Peroxides

open access: yesMolecules, 2016
New hexanuclear nickel(II) silsesquioxane [(PhSiO1.5)12(NiO)6(NaCl)] (1) was synthesized as its dioxane-benzonitrile-water complex (PhSiO1,5)12(NiO)6(NaCl)(C4H8O2)13(PhCN)2(H2O)2 and studied by X-ray and topological analysis.
