Alkane Oxidation: Methane Monooxygenases, Related Enzymes, and Their Biomimetics.

Chemical Reviews, 2017
Methane monooxygenases (MMOs) mediate the facile conversion of methane into methanol in methanotrophic bacteria with high efficiency under ambient conditions.

Surface Freezing and Molecular Miscibility of Binary Alkane–Alkane and Fluoroalkane–Alkane Liquid Mixtures

The Journal of Physical Chemistry B, 2014
The surface freezing (SF) of liquid n-heptadecane (C17)-n-octadecane (C18) and 1-perfluorooctyl decane (F8H10)-C18 mixtures were studied by surface tension and external reflection absorption FTIR (ERA-FTIR) measurements. The surface tension versus temperature curves of all pure liquids show a sharp break point at Ts corresponding to a surface liquid ...

Perfluorocarbons and Semifluorinated Alkanes

Seminars in Ophthalmology, 2000
The introduction of perfluorocarbons (PFCs) and, more recently, semifluorinated alkanes (SFAs) has greatly facilitated vitreoretinal surgery. A distinction is made between the use of these substances as intraoperative tools and internal tamponade agents.

Nanoconfinement Effect on n-Alkane Flow

Journal of Physical Chemistry C, 2019
Nanoconfinement induces change of microscopic structures of n-alkanes, which, in turn, alters their dynamics.

Liquid−Liquid Interfaces of Semifluorinated Alkane Diblock Copolymers with Water, Alkanes, and Perfluorinated Alkanes

The Journal of Physical Chemistry B, 2008
The liquid-liquid interface between semifluorinated alkane diblock copolymers of the form F3C(CF2)n-1-(CH2)m-1CH3 and water, protonated alkanes, and perfluorinated alkanes are studied by fully atomistic molecular dynamics simulations. A modified version of the OPLS-AA (Optimized Parameter for Liquid Simulation All-Atom) force field of Jorgensen et al ...

Structure–Activity Relationships in Alkane Dehydrogenation on γ-Al2O3: Site-Dependent Reactions

ACS Catalysis, 2018
A promising route to produce olefins, the building blocks for plastics and chemicals, is the nonoxidative dehydrogenation of alkanes on metal oxides, taking advantage of the Lewis acid–base surface functionalities of the oxides.

Microbial Biosynthesis of Alkanes [PDF]

Science, 2010
Toward Alkane Synthesis Alkanes are major components of fossil fuels, and synthesis of alkanes remains a challenge in the conversion of renewable raw materials to fuels. Even though diverse organisms synthesize alkanes, synthesis pathways have remained elusive. Now Schirmer et al.

Gesättigte Kohlenwasserstoffe (Alkane)

1985
Das einfachste offenkettige Alkan ist das Methan, CH 4 . Durch sukzessives Hinzufugen einer CH2-Gruppe last sich daraus die homologe Verbindungsreihe der Alkane mit der Summenformel CnH2n+2 ableiten. Eine homologe Reihe ist eine Gruppe von Verbindungen, die sich um einen bestimmten, gleichbleibenden Baustein unterscheiden.

Interfacial alkane films

Physical Review Letters, 1992
Adsorbed {ital n}-hexadecane films of thickness {similar to}10, 20, and 40 A are studied at 350 K via molecular-dynamics simulations. In the thickest film periodic oscillations of the density extend {similar to}18 A from the solid-liquid interface, the roughness fluctuations at the liquid-vapor interface are Gaussian, and the density tail is fitted by ...
