Kinetic evidence for five-coordination in AlOH(aq)2+ ion.
Thomas W. Swaddle,Jörgen Rosenqvist,Ping Yu,Eric J. Bylaska,Brian L. Phillips,William H. Casey +5 more
TL;DR: The kinetics of proton and water exchange on aqueous AlIII, coupled with Car-Parrinello simulations, support a five-coordinate Al(H2O)4OH2+ ion as the predominant form of AlOH(aq)2+ under ambient conditions, which contrasts AlIII with other trivalent metal aqua ions, for which there is no evidence for stable pentacoordinate hydrolysis products.
Journal ArticleDOI
Dynamics and structure of hydration water on rutile and cassiterite nanopowders studied by quasielastic neutron scattering and molecular dynamics simulations.
Eugene Mamontov,Lukas Vlcek,D. J. Wesolowski,Peter T. Cummings,Wenyong Wang,Lawrence M. Anovitz,Jörgen Rosenqvist,C. M. Brown,⊥,# and,V. García Sakai +8 more
TL;DR: In this paper, the diffusion dynamics of hydration water in nanopowder rutile (TiO2) and cassiterite (SnO2), which possess the same crystal structure with the (110) crystal face predominant on the surface, were analyzed using time-of-flight and backscattering neutron spectrometers.
Journal ArticleDOI
Protonation and charging of nanosized gibbsite (α-Al(OH)3) particles in aqueous suspension
TL;DR: In this paper, a synthetic gibbsite was prepared and thoroughly characterized using X-ray diffraction, high-resolution transmission electron microscopy, atomic force microscopy and Fourier transform infrared technology.
Journal ArticleDOI
Surface protonation at the rutile (110) interface: explicit incorporation of solvation structure within the refined MUSIC model framework.
Michael L. Machesky,Milan Predota,Milan Predota,David J. Wesolowski,Lukas Vlcek,Lukas Vlcek,Peter T. Cummings,Peter T. Cummings,Jörgen Rosenqvist,Moira K. Ridley,James D. Kubicki,Andrei V. Bandura,Nitin Kumar,Jorge O. Sofo +13 more
TL;DR: The detailed solvation structure at the (110) surface of rutile (alpha-TiO2) in contact with bulk liquid water has been obtained primarily from experimentally verified classical molecular dynamics simulations of the ab initio-optimized surface and results are used to explicitly quantify H-bonding interactions, which are then used within the refined MUSIC model framework to predict surface oxygen protonation constants.
Journal ArticleDOI
Comparison of the adsorption of o-phthalate on boehmite (gamma-AlOOH), aged gamma-Al2O3, and goethite (alpha-FeOOH)
TL;DR: This work is concerned with the adsorption of o-phthalate (1,2-benzenedicarboxylate) at the water-metal (hydr)oxide interface, and identifies bonding mechanisms, stoichiometries, and stabilities of the formed complexes, and comparing these among the three systems.
