Conformations of myoglobin-derived peptides at the air-water interface
Cheung, David L. (American Chemical Society, 2016-04-14)The conformational change exhibited by proteins at liquid interfaces, such as the air-water and oil-water interfaces, has long been of interest, both for understanding protein structure outside of native environments and ... -
Design principles for the formation of ordered patterns in binary mixtures of colloidal particles on spherical droplets
Fortuna, Sara; Cheung, David L. (Elsevier, 2017-03-11)We elucidate the design principles for the formation of ordered structures formed by binary mixtures of particles on spherical surfaces, such as emulsion droplets, polymer vesicles, and col- loidal nanoparticles. Using ... -
Effect of substrate geometry on liquid-crystal-mediated nanocylinder-substrate interactions
Cheung, David L.; Allen, Michael P. (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 ... -
How stable are amphiphilic dendrimers at the liquid liquid interface?
Cheung, David L.; Carbone, Paola (Royal Society of Chemistry, 2013)By means of molecular dynamics simulations the free energy of adsorption of model dendrimer characterized by monomers of different chemical affinity is predicted as a function of the number and position of the monomers. ... -
Interaction of nanoparticles with ideal liquid-liquid interfaces
Cheung, David L. (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 ... -
Liquid-crystal-mediated force between a cylindrical nanoparticle and substrate
Cheung, David L. (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 ... -
Molecular simulation of hydrophobin adsorption at an oil-water interface
Cheung, David L. (American Chemical Society, 2012-05-16)Hydrophobins are small, amphiphilic proteins expressed by strains of filamentous fungi. They fulfill a number of biological functions, often related to adsorption at hydrophobic interfaces, and have been investigated for ... -
Molecular structure and phase behaviour of hairy-rod polymers
Cheung, David L.; Troisi, Alessandro (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 ... -
Monte Carlo simulations of liquid crystals near rough walls
Cheung, David L. (American Institute of Physics, 2005-02-15)The effect of surface roughness on the structure of liquid crystalline fluids near solid substrates is studied by Monte Carlo simulations. The liquid crystal is modeled as a fluid of soft ellipsoidal molecules and the ... -
Stability of Janus nanoparticles at fluid interface
Cheung, David L.; Bon, Stefan A. F. (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 ... -
Structure of molecular liquids: cavity and bridge functions of the hard spheroid fluid
Cheung, David L. (American Physical Society, 2006-06-28)We present methodologies for calculating the direct correlation function c(1,2), the cavity function y(1,2), and the bridge function b(1,2), for molecular liquids, from Monte Carlo simulations. As an example we present ...
