Molecular dynamics simulations have been used to compute the surface tension of linear alkanes. The OPLS force field has been compared with the SKS force field for alkanes (n-hexane, n-decane and n-hexadecane) over two ranges of temperature: high temperatures where no experimental data are ...
The new low molecular weight gelator 1 can reversibly form stable gels in low concentrations (e.g., 1:800 for n-hexane) with isopropanol and a variety of apolar organic solvents. The gels were studied with differential scanning calorimetry and a combination of electron microscopy techniques, ...

Generally, hydrocarbon derivatives of low molecular weight, e.g., methane, ethane, and propane, are gases; those of intermediate molecular weight, e.g., hexane, heptane, and octane, are liquids; and those of high molecular weight, e.g., eicosane (C20H42) and polyethylene, are solids. ...
The effect of n-alkenes, i.e., propylene, 1-butene, 1-pentene, 1-hexane, and 2-octene, on the yield and molecular weight of polyisobutene obtained with AlCl3 catalyst in n-pentane solvent at â78°C has been investigated. It has been found that the lower 1-alkenes are ...
All fibers were obtained by extrusion in concentrations of 0.04 to 60% m/m of PAO100 oil, with screw rotation speed increasing from 20 to 60 rpm, leaving the extruder nozzle of 1.82 mm. Besides, n-hexane was used in the process of extracting oil from UHMWPE fibers. The fibers did not...
After the appropriate reaction time, the polymer was precip- itated in n-hexane and dried in vacuo up to a constant weight. Chemical Modification of the End-Group of PCL Hexamethyldisilazane in toluene (2.0 wt%) was added into toluene solution of PCL and subject to react on the oil-bath...
In particular, with long-chain hydrocarbons from n-octane to n-tetradecane a right shift was observed, whereas with short-chain or cyclic hydrocarbons such as n-hexane or cyclohexane the maximum viscosity increases. The two effects are interpreted via an extension of a recently developed ...
