Hydrocarbon fluid inclusion fluorescence: A review
(Springer, 2007)Geological fluid inclusions are small voids that can contain a variety of liquids which are often found in natural minerals and rocks. Typically they are less than 10 micrometres in size that host fossil fluids which existed ... -
Liquid-crystal-mediated force between a cylindrical nanoparticle and substrate
(American Physical Society, 2007-10-25)Using classical density functional theory, the structure of a molecular fluid around a cylindrical nanoparticle near a solid substrate is studied. The solvent-mediated force between the nanoparticle and the substrate is ... -
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 ... -
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 ... -
Frequency domain fluorescence lifetime study of crude petroleum oils
(Springer Verlag, 2008-02-01)Frequency domain (FD) fluorescence lifetime data was collected for a series of 20 crude petroleum oils using a 405 nm excitation source and over a spectral range of similar to 426 to similar to 650 nm. Average fluorescence ... -
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 ... -
Interaction of nanoparticles with ideal liquid-liquid interfaces
(2009)Using molecular simulations the interaction between a noncharged nanoparticle and an ideal liquid-liquid interface is studied. The free energy profile as function of nanoparticle-interface separation is determined using ... -
Molecular structure and phase behaviour of hairy-rod polymers
(Royal Society of Chemistry, 2009)Using dissipative particle dynamics simulations the relationship between molecular architecture and phase behaviour in model hairy-rod polymers is studied. In agreement with experimental and theoretical studies the phase ... -
Stability of Janus nanoparticles at fluid interface
(Royal Society of Chemistry, 2009)Using Monte Carlo simulations the interaction of a nanometre-sized, spherical Janus particle (a particle with two distinct surface regions of different functionality, in this case showing amphiphilic behaviour) with an ... -
Measuring the micro-polarity and hydrogen-bond donor/acceptor ability of thermoresponsive N-isopropylacrylamide/N-tert-butylacrylamide copolymer films using solvatochromic indicators
(application/pdf, 2009)Thin polymer films are important in many areas of biomaterials research, biomedical devices, and biological sensors. The accurate in situ measurement of multiple physicochemical properties of thin polymer films is critical ... -
Quenched-annealed density functional theory for interfacial behavior of hard rods at a hard rod matrix
(AIP Publishing, 2009)We consider a system of mobile hard rods that are immersed in an isotropic matrix of hard rods with quenched positions and orientations. Using quenched-annealed density functional theory the disorder-averaged excess free ... -
