Computer Simulations of Rare Earth Erbium Ion-Extractant Binding at Liquid-Liquid Interfaces
This thesis focuses on understanding the molecular mechanisms underlying the solvent extraction of trivalent lanthanide ions in bulk water and at the aqueous-organic interface. Solvent extraction is a critical process in the separation of rare earth elements, which are essential for technologies …

Chemistry at liquid-liquid interfaces: con- and counter-current extraction and biologically active membranes in microchannels
… (SAM) allows for the stable photo-patterning of liquid-air interfaces within the microchannel. It is also found that these hydrophobic/hydrophilic interfaces allow for stable interfaces between immiscible fluids. Chemistry can be conducted at these interfaces. Reversed-micelle extraction of metal …

A universal approach to stabilize water-oil interface via surfactant self-assembly
Liquid-liquid interfaces represent an advantageous setting for the confinement, manipulation, and controlled assembly of colloids. Stabilizing liquid-liquid interfaces, whether between miscible or immiscible liquids, is crucial for a wide range of applications, including energy storage, …

Characterization of surfactant adsorption at a liquid-liquid interface by drop volume tensiometry
… the adsorption behavior of surfactants at liquid-liquid interfaces. In this work, selected surfactants are tested at the mineral oil-water interface using a drop volume tensiometer. A model is developed to account for the neck formation in suspended drops under certain experimental …

Mineralized Bionanoparticle Pickering Emulsions
… to produce functional nanopatterned surfaces and interfaces by means of Pickering emulsions which were employed in biomimetic hydroxy apatite mineralization to produce inorganic biocompatible surfaces and hollow mineral spheres. The work accounts for the emerging interest and significant …

Janus Particles at Interfaces
… directly influences their adsorption behavior at liquid-liquid interfaces. The adsorption behavior of Janus cylinders at liquid-liquid interfaces was studied using the pendant drop technique. The interfacial tension decreases with increasing Janus cylinder length and concentration. From the time …

Dispersion of particles on liquid surfaces
… flour, pollen, etc.) come in contact with a liquid surface, they immediately disperse. The dispersion can occur so quickly that it appears explosive, especially for small particles on the surface of mobile liquids like water. This explosive dispersion is the consequence of capillary force …

DEVELOPMENT AND APPLICATIONS OF SCANNING ELECTROCHEMICAL MICROSCOPY (SECM)
… of electron transfer and ion transfer at liquid/solid, reactivity/conductivity, or liquid/liquid interfaces, imaging of surface surface fabrication or modification, etc. Therefore, improvements of the SECM technique should be beneficial to many research areas. For the first time, a new …

Interfacial self-assemblies of surfactants at water-oil interfaces
… and micrometer length scales. The immiscible liquid-liquid interfaces which are constrained environment have proved to offer ideal platforms for such endeavors where surface-active nanoparticles or molecules can accumulate and self-assemble. In this thesis, we focus on self-assembly of …

Novels materials based on 2-dimensional arrays of metal nanoparticles and microparticles
… to self-assemble into a monolayer at liquid-liquid interface with the assistance of “promotor” molecules such as TBA+ or TPB- which give a charge-screening effect. In the current work, the first investigation was centred on CTAB which was found to promote nanoparticle self-assembly in …

Electro-catalytic reactions
… of the electron transfer reaction occurring on liquid|liquid interfaces. This mechanism was studied in fully protonated and deprotonated conditions. The extent of the electrochemiluminescence production was shown to be dependent on the degree of the interfacial protonation. Moreover, thedata …

Computation of the rise or fall of a drop through a suspending liquid with no mass transfer: Axisymmetric, transitional and complex regimes
We investigate the buoyant motion of a liquid drop through a suspending liquid for three different liquid-liquid pairs and different drop sizes, covering a range of parameter space including axisymmetric, transitional and complex regimes, in cases for which there is no mass transfer between the …
