Background and interest

Joanna Dziadkowiec pursues her PhD studies at the University of Oslo, working on the experimental project devoted to CaCO3 mineral – solution interfaces. Exposed mineral surfaces are critical regions in rocks and various materials, and possess a major contribution to the overall material strength. Thus, it is of great importance to better understand surface processes, where inorganic solid is in contact with geologically relevant fluids. An additional restraint in such system is spatial confinement, possibly contributing to alteration of mineral dissolution and growth processes occurring in pore spaces and microfractures. After recognizing the major interactions in the inorganic calcite-electrolyte solutions system, the subsequent goal is to manipulate the behavior of the calcite surfaces by the action of certain organic additives. The main experimental tool used in this study is Surface Forces Apparatus, which enables measuring adhesive and repulsive interactions between surfaces within nanometer-range separations.

Joanna graduated from the AGH University of Science and Technology in Poland, and IMACS - International Master in Advanced Clay Science, having background in mineral engineering and clay science. Previously, she was working on the clay mineral – polymer composites, in which a layered aluminosilicate mineral, smectite, was intercalated with polysaccharide molecules in order to modify the adsorptive properties of the clay mineral. Her main research interest is engineering and application of natural mineral materials.

Description of research in NanoHeal: ESR 6

Project title: Experimental determination of interface energy, adhesion and repulsion of nano-confined CaCO3 surfaces with aqueous solutions and organic polymers

Objective: Determine the effects of changing fluid chemistry and organic molecules on interface energy, adhesion and repulsion and dissolution/growth of nano-confined CaCO3 surfaces.

Description: A modification of the Surface Forces Apparatus (SFA) at UIO will allow work with calcite substrates (freshly cleaved Iceland spar calcite or calcite thin films grown on mica by chemical vapour deposition). Normal force measurements give insights into the properties of the confined fluid, such as layering, double layer (surface charge), ion correlations and ion surface adsorption. The challenge and originality of the proposed studies with the SFA is the additional reactivity of the calcite substrate (dissolution) and the nucleation of solids in the gap between the substrates. Besides measurements of the equilibrium thickness of the confined film upon applied stress, the dissolution rate and the force interacting between the surfaces across the confined fluid, the SFA at UIO provides direct 2D visualization of the contact region through the interference spectrum. Thus, crystallite formation and dissolution pattern can be directly observed. Based on these features, four main goals will be pursued: (A) The rate of calcite dissolution under constant load will be investigated upon changes of ionic strength and pH; the results on atomically smooth and rough (i.e. with atomic steps, characterized by AFM) calcite substrates will be correlated with the AFM studies performed by ESR3 and ESR4. (B) Surface forces across the confined fluid upon calcite passivation by controlled adsorption of selected organic molecules will be investigated, and will complement the studies in KU. (C) The conditions required for nucleation and crystallization in the calcite single pore (in the presence and absence of organic matter) will be elucidated. (D) Further objectives are (i) to determine the force of crystallization by determining the load that suppresses crystal growth in the single pore (gap) and (ii) to convert the repulsive structural force across the confined fluid into an attractive force that seals the gap between the surfaces. One attempt to achieve attractive (sealing forces) will consist of functionalizing one of the substrates with specific molecules (self-assembled monolayers or organic macromolecules), while exposing the opposite calcite surface to nucleation and crystallization conditions. This experimental project will be performed in close collaboration with the ESR1 & ESR2 at ICL and ESR5 at UCB.

Expected results: Experimental data that can be compared to model simulations at ICL and UCB.

Planned secondment(s): UCB, M22, 8 weeks, AFM exp. & modelling, LCR, M26, 2 weeks, private sector internship
