Experimental determination, theoretical modeling, and molecular simulation have been combined to describe the bulk phase equilibria (i.e., pressure, liquid, vapor saturated mass densities) interfacial properties concentration, adsorption, tension) for methane + n-decane, n-dodecane, n-tetradecane n-hexadecane binary mixtures at 344.15 K in a pressure range between 0.1 30 MPa. determinations are...

The Mn and Fe complexes of the cross-bridged tetraazamacrocyclic ligands, 4,11-dibenzyl-1,4,8,11-tetraazabicyclo[6.6.2]hexadecane (1), 4,10-dibenzyl-1,4,7,10-tetraazabicyclo[5.5.2]tetradecane (2), 1,4,8,11-tetraazabicyclo[6.6.2]hexadecane (3), and 1,4,7,10-tetraazabicyclo[5.5.2]tetradecane (4) provide new compounds of these elements for fundamental studies and applications. These unsubstituted ...

Solubilization of n-decane, dodecane, tetradecane and hexadecane by monorhamnolipid biosurfactant (monoRL) at concentrations near the critical micelle concentration (CMC) was investigated. The apparent solubility of all the four alkanes increases linearly with increasing monoRL concentration either below or above CMC. The capacity of solubilization presented by the molar solubilization ratio (M...

A series of synthetic 1,n-bis(3-aminopyridinio)-alkane fluorescent probes have been used to determine the ligand binding properties of the acetylcholine receptor purified from Torpedo californica electroplax. At equilibrium, the probes bound to a single class of sites. The binding affinity of the fluorescent decamethonium analogues increased progressively as the number of methylene groups (n) i...

A comparative experimental and numerical study is conducted to establish the significance of the use of single-component over multi-component representatives of biodiesel, diesel and their blend for predicting spray tip penetration. Methyl oleate and methyl laurate are used as single-component representative fuels for biodiesel. The pure components n-heptane, n-dodecane and n-tetradecane are us...

The adsorption of fatty acid, kerosene and acid-kerosene on fluorapatite (001) surface were investigated by density functional theory (DFT) calculations. results showed that the single acid could form stable chemisorption O acids bonding with Ca1 site. not be stably adsorbed because H did hydrogen bond PO<sub>4</sub><sup>3-</sup> (O<sub>surf</sub>). For coads...

Dilute solutions of two polar end-functionalized linear alkanes (1-hexadecylamine and palmitic acid), each dissolved in tetradecane, were confined between two mica surfaces and investigated using a surface forces apparatus modified to study shear nanorheology. These two solutions showed similar nanorheological properties that differed from those observed for pure n-alkanes. In static measuremen...
