Perfluorocarbons and Semifluorinated Alkanes
Seminars in Ophthalmology, 2000The 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.

Journal of the American Society for Mass Spectrometry, 2022
Chemical characterization of complex mixtures of large alkanes is critically important for many fields, including petroleomics and the development of renewable transportation fuels. Tandem mass spectrometry is the only analytical method that can be used to characterize such mixtures at the molecular level.

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 ...

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 ...

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 ...

Ab initio computations, up to CCSD(T)/CBS on model systems, and MP2/cc-pVTZ and DFT calculations are performed on cation-alkane and cation-alkene complexes, cation = Li(+), Na(+), Be(2+), Mg(2+), Ca(2+), Cu(+) and Zn(2+); alkane = C(n)H2(n+2) (n = 1-10) and C6H12; and alkene = C2H4 and C6H6.

Positive ions in alkane and mixed alkane glasses
The Journal of Physical Chemistry, 1981Alkane and mixed alkane glasses have been studied by pulse radiolysis. The spectrum for squalane (SQ) was found to be made up of contributions from both the trapped electron and the primary positive ion of squalane (SQ/sup +/). Charge transfer between the solvent positive ion and solute has been directly observed for the first time in mixed alkane ...

Microbial Biosynthesis of Alkanes
Science, 2010Toward 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.
