Manganese tetraoxide based polyalkenoate cements.
(2006)
Polyalkenoate cements resulting from reaction between Mn3O4 with acrylic acid and poly(acrylic acid) have been analyzed by Fourier transform infrared spectroscopy (FTIR) and x-ray photoelectron spectroscopy (XPS). This ...
Characterization of hollow fiber properties during the melt spinning process.
(2000)
Substitution of hollow fibers for solid fibers would not only preserve the web properties (opacity and compression), but would actually improve the strength of each fiber. Hence, hollow fibers could be substituted for solid ...
Optimal design of crude oil distillation plants.
(2001)
Crude distillation is the first processing unit in the refinery. It separates the crude in to distillates, which are either intermediate products further processed or raw materials for the chemical industry. Crude distillation ...
An investigation into the properties and behaviors of alkyldiphenyl oxide disulfonate surfactants.
(2001)
An overview of surfactant adsorption included a discussion of the importance of surfactant adsorption in petroleum applications, a summary of the history of surfactant adsorption research and the mechanisms that have been ...
Solubilization of oil mixtures in anionic surfactant microemulsions.
(2004)
Surfactant enhanced aquifer remediation technology offers great potential to clean up oil contaminants. For oil mixture contaminants the remediation efficiency can vary significantly between the different oil components. ...
Novel platinum/KL catalysts for the aromatization of N-hexane.
(2000)
Finally, regeneration of Pt/KL catalysts was studied for sulfur poisoned catalysts. While air effectively burned off coke deposits, sintering of Pt resulted. An oxychlorination treatment effectively redispersed the Pt.
Characterization of admicellar polymerized and other thin films using scanning probe microscopy (SPM).
(2001)
Characterization techniques and results of polymer and inorganic thin films using Scanning Probe Microscopy (SPM) were presented. In view of principle, equipment and operation of SPM sample preparation, and surface ...
Adsorbed surfactant at the solid/liquid interface: Use of adsorbed surfactant aggregates in the synthesis of electrically conducting polymers.
(2003)
The underlying theme to this work is surfactant adsorption at the solid/liquid interface. More specifically, surfactant adsorption has been studied in relation to the critical micelle concentration (cmc) and to the ...
Single-wall carbon nanotubes production by heterogeneous catalytic reaction.
(2000)
A synergistic effect between Co and Mo has been observed. When both metallic species are simultaneously present, particularly when Mo is in excess, the catalyst is very effective. However, when they are separated they are ...
Simulation of small-angle scattering patterns via a Monte-Carlo technique.
(2000)
Small angle scattering (SAS) is sensitive to morphology on the nanometer length scale but data analysis can be somewhat difficult. Analytical models exist to analyze SAS data but some morphologies do not have realistic ...
