Optical Properties of a Tapered Optical Fiber Coated with Alkanes Doped with Fe3O4 Nanoparticles

open access: yesSensors, 2022
The presented research shows the possibilities of creating in-line magnetic sensors based on the detection of changes of light propagation parameters, especially polarization, obtained by mixing Fe3O4 nanoparticles with hexadecane (higher alkane ...

Compound-Specific Isotope Analysis of Diesel Fuels in a Forensic Investigation

open access: yesFrontiers in Chemistry, 2015
Compound-specific isotope analysis (CSIA) offers great potential as a tool to provide chemical evidence in a forensic investigation. Many attempts to trace environmental oil spills were successful where isotopic values were particularly distinct. However,

Wide diversity of methane and short-chain alkane metabolisms in uncultured archaea

open access: yesNature Microbiology, 2019
Methanogenesis is an ancient metabolism of key ecological relevance, with direct impact on the evolution of Earth’s climate. Recent results suggest that the diversity of methane metabolisms and their derivations have probably been vastly underestimated ...

From leaf to soil: n-alkane signal preservation, despite degradation along an environmental gradient in the tropical Andes [PDF]

open access: yesBiogeosciences, 2020
The relative abundance of n-alkanes of different chain lengths obtained from ancient soils and sediments have been used to reconstruct past environmental changes. However, interpretation of ancient n-alkane patterns relies primarily on modern plant wax n-

Enzymes and Genes Involved in Aerobic Alkane Degradation

open access: yesFrontiers in Microbiology, 2013
Alkanes are major constituents of crude oil. They are also present at low concentrations in diverse non-contaminated because many living organisms produce them as chemo-attractants or as protecting agents against water loss.

Plant n-alkane production from litterfall altered the diversity and community structure of alkane degrading bacteria in litter layer in lowland subtropical rainforest in Taiwan [PDF]

open access: yesBiogeosciences, 2018
n-Alkane and alkane-degrading bacteria have long been used as crucial biological indicators of paleoecology, petroleum pollution, and oil and gas prospecting.

Influence of the carbon atom numbers and the structure of collectors on the coal fines flotation

open access: yesCogent Engineering, 2017
This paper highlighted measuring the contact angle, the wetting heat and the IR spectrum before and after interactions between eight alkanes and coals to investigate the influence of the alkane structure and the number of carbon atoms on the coal surface

Arabidopsis CER1-LIKE1 Functions in a Cuticular Very-Long-Chain Alkane-Forming Complex1

open access: yesPlant Physiology, 2018
The characterization of a further cuticular alkane synthesis enzyme in Arabidopsis supports a model in which several alkane-forming complexes with distinct chain-length substrate specificities coexist in plants.

Bioengineering for the Microbial Degradation of Petroleum Hydrocarbon Contaminants

open access: yesBioengineering, 2023
Petroleum hydrocarbons are relatively recalcitrant compounds, and as contaminants, they are one of the most serious environmental problems. n-Alkanes are important constituents of petroleum hydrocarbons.
