Effects of the Alkane on the Oxygen Reduction Reaction on Well-Defined Pt Surfaces

open access: yesElectrochemistry, 2020
Previous study shows that tetra-n-hexylammonium cation (THA+), which is composed of one nitrogen atom and four alkyl chains, increases the activity of the oxygen reduction reaction (ORR) on Pt(111) eight times as high as that of bare Pt(111).

Numerical investigations of C1-C3 alkanes and H2 premixed flame-wall interaction: Effectiveness of insulation wall on heat loss reduction

open access: yesJournal of Thermal Science and Technology, 2020
Conjugate heat transfer analyses of premixed flames propagating toward the insulation or Al alloy wall are performed for C1 to C3 alkanes and H2 flames at different equivalence ratios of φ = 0.6, 0.8, 1.0 and 1.2 under a high pressure condition of 2MPa ...

Charge Transport through Polyene Self-Assembled Monolayers from Multiscale Computer Simulations [PDF]

open access: yes, 2008
We combine first-principles density-functional theory with matrix Green’s function calculations to predict the structures and charge transport characteristics of self-assembled monolayers (SAMs) of four classes of systems in contact with Au(111 ...

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 ...

Insights into the Ecological Roles and Evolution of Methyl-Coenzyme M Reductase-Containing Hot Spring Archaea [PDF]

open access: yes, 2019
Several recent studies have shown the presence of genes for the key enzyme associated with archaeal methane/alkane metabolism, methyl-coenzyme M reductase (Mcr), in metagenome-assembled genomes (MAGs) divergent to existing archaeal lineages.

Hydrocarbon Desaturation in Cyanobacterial Thylakoid Membranes Is Linked With Acclimation to Suboptimal Growth Temperatures

open access: yesFrontiers in Microbiology, 2021
The ability to produce medium chain length aliphatic hydrocarbons is strictly conserved in all photosynthetic cyanobacteria, but the molecular function and biological significance of these compounds still remain poorly understood.

Performance of the major semiempirical, ab initio, and density functional theory methods in evaluating isomerization enthalpies for linear to branched heptanes [PDF]

open access: yes, 2010
The gas phase standard state (298.15 K, 1 atm) isomerization enthalpy prediction performance of the major semiempirical, ab initio, and density functional levels of theory was investigated using the linear to branched heptanes.

Generation and resource potential of abiogenic alkane gas under organic–inorganic interactions in petroliferous basins

open access: yesJournal of Natural Gas Geoscience, 2021
The generation mechanism of abiogenic alkane gas and whether the gas has industrial values are the focus of international attention. CH4 generated by Fischer–Tropsch synthesis is an important constitutent of abiogenic alkane gas.
