Monte Carlo simulations of liquid crystals between microstructured substrates
(American Institute of Physics, 2008)
The structure of a model liquid crystalline fluid confined between two microstructured substrates is studied through Monte Carlo simulations. A simple model for a structured substrate, similar in spirit to those used for ...
Analysis of hydrocarbon bearing fluid inclusions HCFI) using time-resolved fluorescence spectroscopy
(Society of Photo-optical Instrumentation Engineers, 2005)
Hydrocarbon-bearing fluid inclusions (HCFI) are microscopic cavities within rocks that are filled with petroleum oil, the
composition of which may not have changed since the trapping event. Thus, the composition of that ...
Influence of chemical composition on the fluorescence lifetimes of crude petroleum oils
(Society of Photo-optical Instrumentation Engineers, 2003)
Fluorescence based methods are increasingly being used for the analysis of crude oils because they offer high speed, low
cost, non-contact, and non-destructive testing options. The fluorescence of crude oils is due to the ...
Syntheses of C-substituted icosahedral dicarbaboranes bearing the 8-dioxane-cobalt bisdicarbollide moiety
(Elsevier, 2009-11-20)
The treatment of 1,2-, 1,7- and 1,12-carbaborane lithiated isomers with [3,3′-Co-8-(CH2CH2O)2-(1,2-C2B9H10)-(1′,2′-C2B9H11)] (1) at molar ratios 1:1 or 1:2 at room temperature in THF leads generally to the formation of a ...
Metallacarboranes as building blocks for polyanionic polyarmed aryl-ether materials
(American Chemical Society, 2008-09-20)
Polyanionic species have been obtained in high yield by a new route in the ring-opening reaction of cyclic oxonium [3,3′-Co(8-C4H8O2-1,2-C2B9H10)(1′,2′-C2B9H11)] (2) by using carboxylic acids, Grignard reagents, and ...
Effect of substrate geometry on liquid-crystal-mediated nanocylinder-substrate interactions
(American Institute of Physics, 2008)
Using classical density functional theory, the liquid crystal (LC)-mediated interaction between a cylindrical nanoparticle and a structured substrate is studied. The surface is structured by cutting a rectangular groove ...
