Available in PDF, EPUB and Kindle. Book excerpt: Liquid-liquid interfaces serve as ideal 2-D templates on which solid particles can self-assemble into various structures. These self-assembly processes are important in fabrication of micron-sized devices and emulsion formulation. At oil/water interfaces, these structures can range from close-packed aggregates to ordered lattices. By incorporating an ionic liquid (IL) at the interface, new self-assembly phenomena emerge. ILs are ionic compounds that are liquid at room temperature (essentially molten salts at ambient conditions) that have remarkable properties such as negligible volatility and high chemical stability and can be optimized for nearly any application. The nature of IL-fluid interfaces has not yet been studied in depth. Consequently, the corresponding self-assembly phenomena have not yet been explored. We demonstrate how the unique molecular nature of ILs allows for new self-assembly phenomena to take place at their interfaces. These phenomena include droplet bridging (the self-assembly of both particles and emulsion droplets), spontaneous particle transport through the liquid-liquid interface, and various gelation behaviors. In droplet bridging, self-assembled monolayers of particles effectively "glue" emulsion droplets to one another, allowing the droplets to self-assembly into large networks. With particle transport, it is experimentally demonstrated the ILs overcome the strong adhesive nature of the liquid-liquid interface and extract solid particles from the bulk phase without the aid of external forces. These phenomena are quantified and corresponding mechanisms are proposed. The experimental investigations are supported by molecular dynamics (MD) simulations, which allow for a molecular view of the self-assembly process. In particular, we show that particle self-assembly depends primarily on the surface chemistry of the particles and the non-IL fluid at the interface. Free energy calculations show that the attractive forces between nanoparticles and the liquid-liquid interface are unusually long-ranged, due to capillary waves. Furthermore, IL cations can exhibit molecular ordering at the IL-oil interface, resulting in a slight residual charge at this interface. We also explore the transient IL-IL interface, revealing molecular interactions responsible for the unusually slow mixing dynamics between two ILs. This dissertation, therefore, contributes to both experimental and theoretical understanding of particle self-assembly at IL based interfaces.

Download or read book Polarization and Self assembly at Metal organic Interfaces written by Kshitij Chandra Jha and published by . This book was released on 2012 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation contributes to the understanding of driving forces of self-assembly processes leading to the growth and self assembly of metal nanostructures for nanoelectronic, sensor, and drug delivery applications. It remains difficult to image and characterize molecular-level processes by measurement alone so that we have employed molecular simulation to gain more insight into two aspects: (1) the contribution of induced charges in metal nanostructures to the interaction with biomolecules and ionic liquids, (2) and the mechanism of gold nanorod growth. Polarization at {111} and {100} surfaces of gold in contact with water and peptides of different charge state contributes to the binding strength and plays a role in the assembly of metal nanostructures. We computed the attractive energy using the concept of image charges and molecular dynamics simulation in all-atomic resolution. Attractive interactions amount to between -50 and -70 mJ/m2, corresponding to -0.6 kcal/mol per water molecule and variable amounts per amino acid in peptides depending on the charge state (0 to -10 kcal/mol). The main contribution to adsorption on {111} surfaces stems from soft epitaxial interactions and the net contribution of polarization to adsorption is smaller. On surfaces with poor epitaxial fit of the solute molecules such as {100} surfaces, the main contribution to adsorption can be made by polarization, particularly for charged peptides and ionic liquids. Therefore, the magnitude of interfacial polarization can modulate the binding strength of biomolecules or surfactants versus solvent to metal surfaces. The mechanism of shape regulation in the growth of gold nanorods in ionic liquids (ILs) such as 1-Ethyl-3-methylimidazolium ethyl sulfate is initiated by silver underdeposition and modulated by induced surface charge which decreases in the order {110}, {100}, and {111} for gold surfaces. Attractive effect of induced charges is quantified based on our previous work on polarization at metal-biomolecular interfaces in solution. Higher surface corrugation increases the induced charge so that the side surfaces of gold nanorods synthesized in imidazolium based ionic liquids are formed by {110} and {100} faces, in which a higher contribution of induced charges by -2.3 kcal/mol-molecule compared to {111} surfaces accounts for the thermodynamic stability observed in TEM. In a nonionic solvent like water, surface energies of all three faces {110}, {100}, and {111} are about the same and lead to different surface bounds of gold nanorods in combination with capping agents. The adsorption energy of IL molecules on the gold surfaces changes as a function of the number of molecules per unit area depending on packing constraints and network strength between cations and anions. The adsorption energy per molecule saturates once flat-on molecular multilayers are formed. We suggest that the balance between induced charges, soft epitaxy, and silver underdeposition contributes to the anisotropic growth of gold nanorods in a given solvent.
