Systematic analysis of surface titration data from the literature has been performed for ten oxides (anatase, hematite, goethite, rutile, amorphous silica, quartz, magnetite, δ-MnO2, corundum, and γ-alumina) in electrolytes (LiNo3, NaNO3, KNO3, CsNO3, LiCl, NaCl, KCl, CsCl, NaI, NaClO4) over a wide range ionic strengths (0.001 M–2.9 M) to establish adsorption equilibrium constants capacitances consistent with triple-layer model complexation. Experimental same mineral different given mineral/...
In this study, a method for estimating site types and ionizable densities at mineral surfaces by consideration of ideal crystal has been developed. Periclase, rutile, goethite, hematite, corundum, kaolinite, andalusite, sillimanite, sanidine, albite, anorthite, quartz were considered, both because they represent wide range structures many adsorption dissolution studies have focused on these minerals. For each mineral, the predominant cleavage or growth faces studied. To avoid choosing...
A solvation and electrostatic model has been developed for estimating electrolyte adsorption from physical chemical properties of the system, consistent with triple-layer model. The is calibrated on experimental surface titration data ten oxides hydroxides in electrolytes over a range ionic strengths 0.001 M-2.9 M (Sahai Sverjensky, 1997a). assumes presence single type site, >SOH. It proposed that 1:1 M+L−, logarithms constants (Ks,M+and Ks,L−) representing equilibria >SO− + Maq+ = −...
Bone sialoprotein (BSP) is a highly phosphorylated, acidic, noncollagenous protein in bone matrix. Although BSP has been proposed to be nucleator of hydroxyapatite (Ca(5)(PO(4))(3)OH), the major mineral component bone, no detailed mechanism for nucleation process elucidated at atomic level date. In present work, using peptide model, we apply molecular dynamics (MD) simulations study conformational effect nucleating motif (a 10 amino-acid residue sequence) on controlling distributions Ca(2+)...
The mineral component of bone, dentin and calcified parts avian tendon, hydroxyapatite (HAP), has non-stoichiometric composition (idealized as Ca10(PO4)6(OH)2), plate-like morphology nanometer size. This unique crystal contributes to the physico-chemical biochemical properties bone. Thus, understanding mechanism for controlled growth HAP nanocrystals is significant in study bone biomineralization. Previous studies have shown that acidic non-collagenous proteins (ANCPs), which are enriched...
Face-specific interfacial energies and structures of water at ionic crystal surfaces play a dominant role in wide range biological, environmental, technological, industrial processes. Nanosized, plate-shaped crystals calcium phosphate (CaP) with nonideal stoichiometry hydroxyapatite (HAP, ideal Ca10(PO4)6(OH)2) comprise the inorganic component bone dentin. The shape size contribute significantly to these tissues' biomechanical properties. Plate-shaped HAP can be grown presence biomolecules,...
Understanding the molecular structural and energetic basis of interactions between peptides inorganic surfaces is critical to their applications in tissue engineering biomimetic material synthesis. Despite recent experimental progresses identification functionalization hydroxyapatite (HAP)-binding peptides, mechanisms with HAP are yet be explored. In particular, traditional method dynamics (MD) simulation suffers from insufficient sampling at peptide–inorganic interface that renders...
The single-site Solvation, Bond Strength, and Electrostatic (SBE) model accounts for the anomalous position of silica onthe surface acidity versus aqueous correlation developed metal oxides, by considering solvation energy change in protonation reaction implemented through dielectric constant (1/epsilon(k)) electrostatic Pauling bond strength to length ratio (s/r) oxide. I address here why inclusion solid's brings into same as other oxides like TiO2, Al2O3, Fe2O3. contributions are...
