Structure of Barite (001)− and (210)−Water Interfaces

et al. 2001

The structures of the barite (001) and (210) cleavage surfaces were measured in contact with deionized water at 25°C. High resolution (∼1 Å) specular X-ray reflectivity and atomic force microscopy were used to probe the step structures of the cleaved surfaces and the atomic structures of the barite-water interfaces including the structures of water near the barite-water interfaces. The barite (001) and (210) cleavage surfaces are characterized by large (>2500 Å) domains separated by unit-cell steps (7.15 and 3.44 Å steps for the (001) and (210) surfaces, respectively). This observation was unanticipated for the (001) surface in which adjacent BaSO 4 layers are displaced vertically by c/2 and symmetry related through a 2 1 screw axis along (001). The atomic structures of the two cleavage surfaces derived by X-ray reflectivity reveal that near-surface sulfate groups exhibit significant (∼0.4 Å) structural displacements, while Ba surface ion displacements are significantly smaller (∼0.07 Å). Water adsorbs to the barite surfaces in a manner consistent, in both number and height, with the saturation of broken Ba-O bonds; no evidence was found for additional structuring of the fluid water near the surface.

“…22 Less soluble means a weaker interaction with water, and thus less ordering at the interface. The RuO 2 -water interface is the only other example in the literature studied in sufficient detail, 10 and it combines low solubility with little ordering beyond an icelike layer. Recent results by us on NaCl(100) also support this proposed correlation between liquid order and solubility.…”

“…Using transmission electron microscopy, lateral ordering was observed qualitatively in thicker films. 9 Recently, a single icelike layer was found at the RuO 2 -water interface, 10 and we derived the complete ordering components of a potassium dihydrogen phosphate (KDP) {101} surface in contact with water. 11 From these studies the picture emerges that a liquid in contact with a crystal surface has both solid and liquid properties.…”

Liquid ordering at the Brushite-{010}–water interface

et al. 2004

Using surface x-ray diffraction, we have determined the atomic structure of the ͕010͖ interface of brushite, CaHPO 4 ·2͑H 2 O͒, with water. Since this biomineral contains water layers as part of its crystal structure, special ordering properties at the interface are expected. We found that this interface consists of two water bilayers with different ordering properties. The first water bilayer is highly ordered and can be considered as part of the brushite crystal structure. Surprisingly, the second water bilayer exhibits no in-plane order, but shows only layering in the perpendicular direction. We propose that the low level of water ordering at the interface is correlated with the low solubility of brushite in water.

For benzene, there is a similar but slightly different mechanism of adsorption, in which the adsorbed molecule has a collective interaction with multiple surface atoms.…”

Hydrocarbon tribopolymer, a type of polymer formed due to friction between surfaces, is a major impediment to the development of micro-and nanoelectromechanical systems (MEMS/NEMS) devices for industrial application. Tribopolymer buildup can prevent MEMS and NEMS from making or breaking electrical contact. We describe the adsorption of benzene (C 6 H 6 ) on the RuO 2 (110) surface using density functional theory. This adsorption is an important initial step in the mechanism of hydrocarbon tribopolymer layer formation on MEMS and NEMS devices.The adsorption interaction is studied by considering three oxygen coverages of RuO 2 (110) and all the possible adsorption sites for benzene. We find that adsorption of benzene on O-poor RuO 2 (110) via C-Ru bonds is stronger than adsorption on the O-rich RuO 2 (110) via H-O bonds. For an in-depth study of the adsorption behavior, we include the van der Waals interaction for a holistic investigation. By incorporating the thermodynamic chemical potentials into the adsorption simulations, we describe a model that can provide guidance for realistic situations.
