A comprehensive picture of the interface between aqueous solutions and (110) surface rutile (α-TiO2) is being developed by combining molecular-scale macroscopic approaches, including experimental measurements, quantum calculations, molecular simulations, Gouy−Chapman−Stern models. In situ X-ray reflectivity standing-wave measurements are used to define atomic arrangement adsorbed ions, coordination interfacial water molecules, substrate termination structure. Ab initio calculations dynamics...
Shale formations play fundamental roles in large-scale geologic carbon sequestration (GCS) aimed primarily to mitigate climate change and smaller-scale GCS targeted mainly for CO2-enhanced gas recovery operations. Reactive components of shales include expandable clays, such as montmorillonites mixed-layer illite/smectite clays. In this study, situ X-ray diffraction (XRD) infrared (IR) spectroscopy were used investigate the swelling/shrinkage H2O/CO2 sorption Na(+)-exchanged montmorillonite,...

Continental flood basalts are attractive formations for geologic sequestration of carbon dioxide because their reactive divalent-cation containing silicates, such as forsterite (Mg2SiO4), suitable long-term trapping CO2 mineralized metal carbonates. The goal this study was to investigate at a molecular level the carbonation products formed during reaction with supercritical (scCO2) function concentration H2O adsorbed surface. Experiments were performed 50 °C and 90 bar using an in situ IR...
Wollastonite (CaSiO~3~) dissolution rates were measured at 25°C in 0.01 M NaCl using a mixed-flow reactor as function of pH (5 to 12) and concentration forty organic ligands. Mostly stoichiometric was observed these conditions. For seven ligands (acetate, citrate, EDTA, catechol, glutamic acid, 2,4-dihydroxybenzoic glucuronic acid), batch adsorption experiments electrokinetic measurements performed ligand confirmed the interaction with \>CaOH~2~^+^ sites allowed quantification their...
